                            General

Please  note:   the  first task you should perfom after installing
Studio  is  to  adjust  the  gamma  value  of  your monitor in the
printing  program.   In the past, people complained about too dark
output  of  Studio.   Please  note that the gamma value determined
using  the gamma window of Studio only describes the value for the
screen  mode  used  for  displaying  the  gamma  window (ie.  your
Workbench  screen  mode).  This screen mode usualy has a different
gamma value than the value used for displaying your image.

We  will address this problem in one of the next releases.  in the
meantime:   if  your  output of Studio is too dark even if you are
sure  all CMS settings are correct for your setup, LOWER the gamma
value  in Studio's Monitor window until the output has the correct
brightness.   Once  done,  all  your  prints  should  be  fine  in
brightness and color hue.

------------------------------------------------------------------

                             Canon BJC

You   must  have  a  Studio  CanonBJEC  driver  and  CanonBJECPref
installed  in order to get the driver updated by this update disk.
So  first  install  your  Canon  driver  using the standard Studio
disks.   Afterwoods  run  this  update  disk and add new Canon BJC
software  if  wanted.   You  do  not  need  to  have CanonBJEC and
CanonBJECPref installed if you add the Canon BJC4100 and Canon BJC
610 software offered by this update disk.

Different  to  the  manual (V2.09 an ealier), Custom ResX and ResY
defines  the  page  size  for  the  CanonBJ5-230 and CanonBJ-EC in
1/360inch.   The  page  size does include the unprintable margins.
The  driver  will  automaticly  subtract the margins for you.  The
margins  depend  on  the printer and emulation (Extended Emulation
offers a larger printable page size).

Canon  BJC 610 users:  please note that printing 720 dpi using the
Studio Workbench driver requires major color adjustments.  Use the
menu  presets  for  adjusting the driver for 720dpi support.  Note
that  the  Canon  bJC 610 will only print 720 graphics in BJC mode
(extended   emulation).    Whenever  possible,  use  the  printing
program's CMS for printing 720dpi.  BJC 610 should use the BJC 600
profiles  with  the  printing  program.   So  when  installing the
profiles,  select  the BJC 600 and BJC 610 profiles as recommended
by  the  installation  program.   More  Canon  BJC 610  720dpi and
720*360dpi profiles for various dither methods and paper types are
under  development  (see  CompuServe's AmigaUser forum library for
the latest profiles updates).

If you experience strong stripes/banding of 1mm height in your BJC
610  output:   make  sure you run the print head alignment test as
described in the BJC manual.  Also make sure the print head is ok.
Perform  a  printer  nozzles  test  as described in the manual and
clean  the print head several times.  In some cases it can help to
print  20-30  fully  colored pages if the print head was new.  The
stripes are not caused by the printer driver.  However, your print
mode,  dither  method  and paper used are important.  Don't try to
print  high resolution on bad paper.  You rather get worse results
compared  to  360  dpi  dumps.   If  you  do experience 1mm height
stripes,  try  switching  the dither method.  The BJC often prints
less  horizontal  stripes  when  using  an error diffusion (Floyd,
Stucki,...) or Blue Noise dither method.

Canon BJC 4100 users:  please note that printing 720*360 dpi using
the  CanonBJ-EC Workbench driver requires major color adjustments.
Use  the  CanonBJECPref  menu presets for adjusting the driver for
720dpi  support.   Note  that  the  Canon BJC 4100 will only print
720*360dpi  graphics  in  BJC mode (extended emulation).  For best
image  dumps  on  the  Amiga  use  CanonStudio's  CMS for printing
720*360dpi  (only  available to registered users).  BJC 4100 users
should  use  the  BJC  4000 profiles with the printing program for
printing  360dpi.

                 The SetupBJL-BJC4100 Program
                 ----------------------------

For  some  Canon  BJC  4100  users  a  SetupBJL-BJC4100 program is
installed.     The    program   SetupBJL   may   also   be   named
SetupBJL-BJC4100  or  similar identifying the printer to use with.
The  program  can  usualy  be  found  in your systems Prefs drawer
beside the drivers CanonPref program.  The SetupBJL program may be
used  by  Canon  BJ  and  BJC  users  for controlling the printers
permanent settings.  It also allows you to perform certain printer
functions  like test dumps and ink head cleaning.  The use of this
program is very similar to the MS-DOS or Windows program described
in  your  printers  user  manual or DOS print guide.  This chapter
will  only  cover  the  additional Amiga specific functions of the
setup software.  See you printer manuals for more details.

In  most  cases  the printer is shipped to you by the manufacturer
already  setup right for use with the Amiga.  Anyway, if you start
SetupBJL for the first time, it's recommended to run the Setup For
Amiga/EU  action  first.   This  will  setup  the  printer  for ou
automaticly.


SetupBJL   can  be  started  with  various  Tool  Types  or  Shell
arguments:


PUBSCREEN:   SetupBJL opens a window on the default public screen.
You  may  specify a special public screen by setting the Tool Type
"PUBSCREEN=screenname".   The  screen name is case sensitive.  and
the  SetupBJL  program will open its windows on your application's
screen.

TOPAZ:  SetupBJL is font independent.  All text is displayed using
the  system font.  If TOPAZ is specified, only the topaz 8 font is
used.

SAVE:   When  using  this option, SetupBJL will set-up the printer
without  showing  the  set-up  window  first.   This is useful for
controlling  printer  settings  from  batch files.  You can enable
certain  printer  settings  without  user interaction by using the
FROM  option in combination with SAVE.  Settings can be saved from
SetupBJL by using the Save As menu item.

SetupBJL will automaticly quit after 10 seconds if your printer is
off or not connected.

FROM:   SetupBJL  saves the settings sent to the printer in a file
named  SetupBJL.prefs,  placed  in the same drawer as the SetupBJL
program.   Next  time  you  start  SetupBJL,  the  current printer
settings are read from this file and displayed.

FROM  allows you to specify a different settings file for reading.
You  can  save  other settings files than SetupBJL.prefs using the
Save As menu item.


DEVICE:   SetupBJL  usually  sets  up the output device defined in
Workbench  2.04 printer preferences.  Since Workbench 2.04, nearly
any  output  device  can  be  defined  in  preferences for printer
output.   Usually  serial.device  or parallel.device is used.  You
may  alter the device using the case sensitive DEVICE Tool Type or
Shell argument.

UNIT:  Workbench 2.04 (or higher) Printer preferences programs may
enable  you  to  specify a printer port unit to print to.  Most of
the  current multiport cards enable you to specify a port to print
to  using a unit number (0 = internal port, 1 = external port A, 2
= external port B ...).  Using the UNIT tool type or Shell keyword
you can define a unit (port) to print to.

POWEROFF:   When  using  this  option,  SetupBJL will turn off the
printer  without  showing the set-up window first.  This is useful
for  controlling  the  printer  from  batch  files.  SetupBJL will
automaticly  quit  after 10 seconds if your printer is already off
or not connected.



SetupBJL  saves  the  settings sent to the printer in a file named
SetupBJL.prefs, placed in the same drawer as the SetupBJL program.
Next  time  you  start  SetupBJL, the current printer settings are
read from this file and displayed.  This method works only so long
as  SetupBJL  is  used  for all printer setting changes and is not
moved to another directory without the SetupBJL.prefs file.


SetupBJL  offers some printer functions and settings not available
in the MS DOS software:


                      Setup For Amiga/EU

This  Printer Action function will setup the Canon printer for use
with  the Canon Amiga Workbench driver.  The setup is for use with
DIN A4 sized paper wich is mainly used in Europe (EU).

                      Setup For Amiga/US

Same as Setup For Amiga/EU for use with US Letter sized paper.

                       Enable Hex Dump

This Printer Action will set the printer to hex dump mode.

                          Auto On

When  enabled,  the printer will automaticly turn on if you try to
transfer   data   to  the  printer.   The  option  is  usefull  in
combination  with  the Auto Off setting.  It allows you to let the
printer automaticly turn itself on and off as needed.

WARNING:   there have been some reports of Canon BJC 4100 printers
refusing  to  turn off manualy after turning off the computer.  If
you do have such a problem with your printer, turn "Auto On" OFF.

Please note that turning on your computer can cause the printer to
go  on  too.   This  is  a  normal behaviour with Auto On enabled.
Turning  your  printer  on and off too often is also no good idea.
The  printer  does  consume  a  small amount of ink for a cleaning
procedure everytime it is turned on.  It is recommended to use the
Auto Off feature with at least 10 minutes.

                    STUDIO PRINTING PROGRAM

After  three  years  work  Studio's  V2.10  CMS printing system is
finaly  done.   With  release  V2.10  we  finaly have CMYK support
built-in  and  various  precise  profiles.  The system now basicly
allows  you  to  control any color aspect of your printer.  We can
now  concentrate on the rather "simple" things.  V2.11 adds an ink
limit control function.
                             ----

Beside  offering  new Stylus software, the Studio (V2.11) printing
program update is mainly a speed update.  In the worst case, speed
of  Studio  will  only increase by roughly 10%.  But under certain
conditions,  Studio  can  get  10 times  faster than it's previous
2.10d version.

The  speed  increase  depends  on  your settings and the image you
print.   Mainly  the  IFF  ILBM and dither routines offer improved
speed.  So printing large IFF ILBM images - especialy in landscape
mode  -  can  get  much  faster.   The  dither  routines  now skip
left/right   margins   in   the  output  where  no  primary  color
(C,M,Y,K,...)  is  printed.   This  can  dramaticly  improve speed
depending  on the image.  In order to do this - and other upcoming
optimizations - all dither routines had to be completly rewritten.

                             ----

Studio  (V2.11)  now  offers  you to limit the amount of ink/color
printed  using  the  former  Separation window.  The window can be
selected   with   the   "Color..."   windows   using  the  "Color:
Separation, Weights, Usage" gadget.

Note:   you  can  only  limit the amount of ink with disabled CMS.
Otherwise  it's  the CMS profiles task to limit the amount of ink.
When  should  you  use this function?  Usualy whenever your output
without  CMS  becomes  to muddy/dark because of too much ink being
printed.  For instance, let's assume you want to print without CMS
on  a  Stylus  Color  or Canon BJC 610 printer at 720dpi.  In this
case,  limit the amount of ink to 50% per print color.  50% is the
smallest  amount  giving  you full ink coverage on these printers.
In  most  cases,  you  only  have  to  use the gamma slider in the
"Color..."  window  in  order to get good results without CMS.  As
described  in  the  Studio  manual,  there are special cases where
printing without CMS might be wanted.

Users wanting to create profiles should first find out the correct
ink  usage  for the printers before printing the color calibration
images.   Enter the limits into CMSScan afterwoods.  The ink limit
for  your  printer can usualy easily be seen when printing the b/w
greyscale calibration picture with 100% ink usage.

                             ----

Studio   (V2.08)  now  supports  the  PNG  image  format  (PNG  is
pronounced  "ping").   The  PNG  format  is  intended to provide a
portable,  legally  unencumbered,  well-compressed, well-specified
standard  for  lossless  bitmapped  image files.  We hope PNG will
soon  replace  the  well  known  GIF format.  Beside offering more
features   than   GIF,  PNG  also  offers  a  very  good  lossless
compression.   We  are  sure  PNG  will  soon  become a well known
standard beside JPEG/JFIF format used for lossy compression

                             ----

Studio  (V2.09) now supports the PCX image format.  This format is
very  popular  on MS DOS PC's.  Studio supports 1,2,4,8 and 24 bit
PCX  files.   Studio  is also able to print the first image of DCX
images.  DCX images are mainly generated by fax software.

                             ----

Studio  (V2.10)  now  offers a saturation slider in the "Color..."
window.  An additional separation window allows you to control the
separation used by Studio when printing color images without CMS.


                             ----

The  new  separation functions offered are used for converting RGB
screen  colors  to  CMYK  printer  colors.   Please  note that the
separation  settings  are  used  only  if  you print a color image
without  using the CMS.  CMS profiles provide their own separation
settings  as  the  profiles  are  made  for  a specific separation
process.   Changing  the separation process would result in faulty
colors  in  the  output.   However,  you can change the separation
function  used  by  the CMS by changing the profile settings using
CMSEdit.

Studio currently offers five different separation functions:

   Internal  UCR/GCR:   Uses the default internal separation.  The
method  is  simple:   Studio  will  print  a  black dot if a cyan,
magenta  and  yellow  dot  would  otherwise be printed at the same
place.

   Custom   UCR/GCR:    Uses  the  standard  linear  UCR  and  GCR
percentage  settings  defined  by the UCR and GCR integer gadgets.
The  meaning  of  this  setting  is  very  similar to that used by
various DTP and image processing programs on the Amiga.

Under  color  removal  (UCR)  describes  the  practice of removing
quantities  (here  defined  in percentages) of yellow, magenta and
cyan  from where the black is printing -- literally removing color
from under the black.

Greyscale  component replacement (GCR) removes yellow, magenta and
cyan  ink  from  where all three inks print together, and replaces
them  with black.  The black plate carries most of the tone in the
reproduction,  therefore  neutrals  (greys)  are  easier to print.
Again,  you  define  the  percentage  of  how much color should be
replaced.

   Custom  UCR  / Weak GCR:  This setting uses the standard linear
UCR  setting  as  described  above,  but  with a preset "weak" non
linear  grey component replacement function (Weak means less black
is used).  The non linear function results in composite grey being
used  for  bright  shades  and black is only used for dark shades.
This  gives  you  fewer distrurbing black dots in lighter areas of
your output.  The output will look less grainy.

Instead  of  offering  a GCR setting, this method offers a setting
for  defining  the  maximum  percentage of black being used by the
replacement  function.  Usually a value between 80 and 100 percent
gives good results.

"Custom  UCR / Medium GCR":  This setting is similar to Custom UCR
/ Weak GCR.  However, the GCR function will use black for brighter
shades.

"Custom UCR /Strong GCR":  This setting is similar to Custom UCR /
Medium  GCR.   However, the GCR function will use black for bright
shades and the increase of black is nearly linear to the amount of
composite grey of the processed color.

So, when do you need the separation functions?

Mainly  when  not using the CMS or when generating a profile using
the tools (CMSScan) described later in an extra chapter.  There is
no  general  rule  for  which  type  of  separation  is best.  The
"Internal  UCR/GCR"  function  is  very  fast  and  offers  decent
quality.   The  "Custom  UCR/GCR"  function  is mainly offered for
compatibility  with  other  programs.   The  last three non-linear
separation  functions  offer good quality.  If your printer offers
good  ink  coverage  without bleeding and similar problems, Custom
UCR  /  Weak  GCR  gives best results.  For instance, if you own a
normal  inkjet printer, Custom UCR / Weak GCR often gives the best
results  when  using  coated  paper.  Plain paper often results in
rather  worse  output  as too much color ink is being printed.  In
those  cases Custom UCR / Strong GCR might be better.  Simply give
it  a  try  and see what you think is best for your printer, paper
and dither method.

Again  note:   when  generating a CMS profile make sure you select
the  correct  separation  function for your set-up.  Otherwise all
printed calibration pages might be useless because they would have
been made with a bad separation function.

                           ----

Studio  (V2.10)  now  includes  several  output  modules  for  PCL
compatible  printers  (mainly DeskJets and LaserJets).  All output
modules use Hewlett-Packard's "Printer Command Language" (PCL)
in  various  forms.   The  installation  program  will install the
proper output module for your printer.  However, if you can't find
an output module listed for your specific model of printer, choose
an  output  module  that matches your printer's emulation.  We get
many letters asking for output modules for specific printers, even
if  a  generic  module  is available.  In most cases these letters
have  been  unnecessary.   For  instance,  there is not one single
drawback  if  you  use a generic PCL 5C output module instead of a
specific  DeskJet  1200C module.  (PS:  You can use this module in
b/w  mode on Laserjet PCL 5 printers too!!!) The PCL 5C module was
designed  to  work  with  several printers, including the PaintJet
300XL.

The differences between the various DeskJet and PCL output modules
are minor.  Often the output module will offer you settings in the
Config  window  which are already known by the preferences program
for the Workbench driver.  So if you don't find a specific setting
described  here, use the index of the Studio manual to learn about
the meaning of the setting.

First  some  general notes.  Most modern DeskJet printers are able
to  print  600 dpi maximum in greyscale mode, while the color mode
supports only 300 dpi maximum.  If you own Studio V2.10 or higher,
the  program  will  automatically  switch  from color to greyscale
printing if you choose a density of 600 dpi.

When  it comes to color printing, the DeskJet 8xx output module is
a  little  different.  Please note that a printer like the DeskJet
850C  offers 300 dpi color printing similar to the cheaper DeskJet
660C  printer.   But the DeskJet 850C printer also offers 64 color
shades  per  addressable  printer  dot,  compared  to the normal 8
colors.   This  results  in  a  much  better  output  quality when
printing  images.   So  once  the  DeskJet  8xx  output  module is
selected,  the  "Density"  gadget in Studio will also show you the
printable color shades per addressable printer dot.

                           ----

Following  additions  have  been  made  to  the ARexx interface of
Studio V2.10 and V2.11:

VERSION

Returns  the version of the Studio ARexx interface.  Up to version
2.09  Studio  returns 1 in PRTSTUDIO_RESULT.  Version 2.10 returns
2.  Version 2.11 and higher returns 3.

INKLIMIT (GREY|CYAN|MAGENTA|YELLOW|BLACK|TOTAL)
INKLIMIT (GREY|CYAN|MAGENTA|YELLOW|BLACK|TOTAL) Value

Reads or writes the amount of ink limit used for a specific output
color.   Values  of  0 to 100% are supports for all colors.  TOTAL
supports 0-400%.

The  commands  require  Studio  V2.11  or higher.  Use the Version
command for detecting the Studio version.

COLOR
GREYSCALE

Selects  the  default  output print mode.  The previous setting is
returned in PRTSTUDIO_RESULT.  No error is reported.  Note that it
is valid to select COLOR even if the image selected is a greyscale
one  or  the  printer  driver selected doesn't support color.  The
setting   mainly   reflects   the  default  preset.   Studio  will
automatically switch to greyscale printing if required.

The  commands  require  Studio  V2.10  or higher.  Use the Version
command for detecting the Studio version.

SEPARATION
SEPARATION 0-4

Sets  the  type  of  separation  used  when printing a color image
without  using  the  CMS.   The  previous  setting  is returned in
PRTSTUDIO_RESULT.   If  there  was  an  error, RC is set to 10 and
PRTSTUDIO_RESULT  to  "Illegal  value".   The following values are
supported:

0:  Use the default internal separation.

1:  Use the standard linear UCR and/or GCR settings defined by the
UCR and GCR commands.

2:   Use  the standard linear UCR setting with a preset weak (Weak
means less black is used for replacing composite grey.) non linear
grey component replacement function.  The GCR command can be
used  for  defining the maximum percentage of black ink being used
by the replacement function.

3:   Use  the standard linear UCR setting with a preset medium non
linear  grey  component replacement function.  The GCR command can
be  used  for  defining  the maximum percentage of black ink being
used by the replacement function.

4:   Use  the standard linear UCR setting with a preset strong non
linear  grey  component replacement function.  The GCR command can
be  used  for  defining  the maximum percentage of black ink being
used by the replacement function.

The  Separation  command requires Studio V2.10 or higher.  Use the
Version command for detecting the Studio version.

UCR
UCR 0-9999

Sets  or reads the amount of under color removal (UCR) in percent.
The  setting is used depending on the type of Separation selected.
The  previous  setting  is returned in PRTSTUDIO_RESULT.  If there
was  an  error,  RC  is set to 10 and PRTSTUDIO_RESULT to "Illegal
value".

The  UCR command requires Studio V2.10 or higher.  Use the Version
command for detecting the Studio version.

GCR
GCR 0-9999

Sets or reads the type of grey component replacement (GCR) used by
the  separation  function.   The  meaning  of the GCR value mainly
depends  on  the separation function being used.  The value either
defines the percentage for black generated from a color by the GCR
function,  or  it  defines  the  maximum amount of black ink to be
used.

The  previous  setting  is returned in PRTSTUDIO_RESULT.  If there
was  an  error,  RC  is set to 10 and PRTSTUDIO_RESULT to "Illegal
value".

The  GCR  command  requires  Studio  V2.10  or  higher.   Use  the
"Version" command for detecting the Studio version.

Studio Prof. History:

E = removed bug
C = changed
I = improvement

10.07.95 V2.08  I - Support for the new PNG image format added.
        E - Problem with reading compressed Targa images fixed
        E - Version 2.07 didn't install the SetupPJL program
            for Laserjet 4L users. Users had to select PCL 5e
            during installation for getting SetupPJL.
21.07.95 V2.09  I - PCX file format support added
        I - DCX file format support added
27.11.95 V2.10  I - Switched to SAS/C V6.56 compiler. Optimizer now
            seems to work fine and thus was fully enabled.
        I - This is the major improvement in V2.10:
            Scaling,
            Dithering,
            Border handling,
            Effects,
            CMS,
            and much more...
            rewritten for complete CMYK(!!!) processing.
            Slightly faster too.
        I - And this is the second major step:
            CMS now accepts CMYK profiles and profiles with
            various precission.
        I - Saturation control added to the color window.
        I - Update to PNG compression library
        E - BNoise b/w dither method was not reentrant
            since V2.07. Now reentrant again.
        I - Separation functions/settings added.
            Binary CMY->CMYK and CMYK->CMY functions
            added beside the standard UCR/GCR functions.
        I - SEPARATION [0-4], UCR [0-9999], GCR [0-9999],
            GREYSCALE, COLOR and SATURATION [-50 - 50]
            Arexx commands added. Arexx Version command
            will now report "2" to reflect the changes.
        E - A problem reported by a user when printing from ARexx
            hopefully got fixed - even though I couldn't repeat
            the problem on my machine. The problem seems to cause
            dark/black images being printed when not using the
            the PANEL command prior to PRINT or PRINT WAIT.
        I - Blue Noise non binary dither method (previously
            only used by Fargo output module) now much faster.
            Also fixed: BNoise 30% was printed as 50%.
        I - Studio Version is now supplied to the output module.
        I - Studio will now switch to greyscale printing
            for a specified print density if output module
            doesn't support color printing for a specific
            resolution. For instance, a Deskjet 660C can
            only print greyscale at 600dpi.
        I - Added additional functions to Studio server
            for upcoming PageStream V3 server printer driver.
            These functions offer an easy way to a
            future setup window of the PageStream driver.
        E - Canon BJC800 output module didn't allowed
            paper width greater 8.5 inch. Because of this,
            users had to use the slower Workbench driver
            for printing A3. Similar problems with right
            margin do exist with other Canon modules
            when printing 180 dpi. Fixed.
        I - A bug in the BSC/Alpha Data Multiface III
            pit.device can cause a lockup of any print
            program with a priority below 0. All output
            modules will now open pit.device with
            a changed priority of zero unless priority
            was set to high by user (in this case
            pit.device is always accessed with
            priority 0 anyway).
        I - Canon BJC 610, Deskjet 8xx, 6xx, 1600 and
            PCL 5C output module with CRet and TES (REt)
            support added. Also drivers and profiles
            added for these new printers.
        E - CanonBJ-EC right margin problems when using
            a different density than 360dpi fixed.
        I - 1200 dpi PJL and Max Res setting added to
            LaserDriver for Lexmark Optra 1200dpi laser
            printers. (not included with this update disk)
23.12.95 V2.10b C - Recompiled without SAS/C Peephole Optimizer
            (just to make sure... as it seems the Optimizer
            still didn't worked right).
        E - DeskDriver4C might print 3-4 unwanted characters
            on a page with some programs. Fixed.
        E - Fargo Primera greyscale printing problems fixed.
        I - PCL_5C output module now works with some
            none 100% compatible PCL 5 printers. Faster too.
20.02.96 V2.10c
20.02.96 V2.10d C - Recompiled with SAS/C Peephole Optimizer
        E - Fixed a CMS bug introduced with V2.10 causing
            minor color faults for certain colors/profiles.
        E - Fixed histogram/clipping function. Output
            was far to dark for certain images.
        I - Added CanonBJC4100 driver, output module
            and profiles (update disk only).
        I - Added CanonBJC 4100 SetupBJL software.
21.04.96 V2.11    I - ALL dither routines completly rewritten in
            order to suit upcoming optimize functions
            and image preview.
        I - Right/Left margin handling of dither
            routines is optimized depending on
            image contents. When effectiv,
            can lead to 1000% speed increase...
        I - Following functions have been translated
            to fast assembler code (% faster):
            - serpentine binary dither routines (30%)
            - IFF ILBM read routines (50%)
            - sharp/blur functions (10%)
            - 3d interpolation of CMS (10%)
        I - Added Epson SetupStylus software.
        I - Added StylusColor/IIS/II output module.
        I - Added 360*720 dpi mode to EpsonP2
        I - New Stylus Color/II/IIS profiles
        I - Some DJ 6xx/8xx profiles changed/added
        I - Output modules are now listed
            in alphabetical order. Doubleclick
            can be used for selection.
        E - The blur/sharp filter wasn't giving
            full quality with Fargo Primera.
        I - CMSScan ink limit settings added.
        I - CMSScan now applies a filter to CMYK
            profiles removing unwanted dots
            in the output. This means introducing
            faults to the profile for the benefit
            of better output.
        E - DJ 6xx printers don't print correct
            at 600*600 dpi without presentation
            quality turned on. Drivers now
            automaticly enable presentation mode
            when needed.
        E - DeskDriver V2.10/V2.10b sometimes
            printed 3 chars on a gfx page. Fixed.
21.04.96 V2.11b E - Fixes the Error 50 problem in V2.11 after
            selecting top output module from the list.
        E - Added a check avoid bad ink limit setups
            causing blank pages without CMS.
05.05.96 V2.11c E - Printing program V2.11(b) didn't load
            8 Bit IFF ILBM greyscale image with colormap
            correctly. Works again now...
        I - Installation program avoids "String To Long"
            error message reported by users who
            accidently removed the ENVARC:STUDIOPATH
            var.
10.06.96 V2.12  I - PageStream 3.0i Server driver added
        I - Improved server interface
        E - 2 color IFF ILBM images were not loaded
            correctly by new V2.11 routines. Fixed
        E - print dimension rectangle in window was wrong for
                    VERY large (>900 inch!) posters. Fixed
05.10.96 V2.13    I - PageStream 3.2 beta 6,7,8,9 driver added
        I - All binary dither routines are now up to their final
            speed. This increases the Studio printing program
            speed further by 5-60%.
        I - Recompiled for 68060 and full optimizer.
        I - Now supports progressiv JPEG/JFIF files.
            Note: progressiv images currently must be printed
            from memory.
        I - PNG read routines rewritten for new PNG library
            Version 1.0 beta 3-V0.89 and ZLIB 1.04
        I - Faster image file access implemented in: IFF ILBM,
            IFF DEEP, PBM, PGM, Targa, Gif, PCX, PNG.
        I - Fargo output module (Ver3 Rev0) now writes/reads the
            temporary files much faster (10-15% speed increase).
        E - Effect window gadget scaling didn't worked for some
            fonts when opening the window multiple times. Fixed
        E - Landscape poster printing for small image on computers
            with much memory and a high memory setting might cause
            the second row of pages to get inverted. Fixed
        E - Studio could have crashed if an error occured while
            reading the image data of a PNG file. Fixed.
        E - IFF read buffer underrun could cause Error 48 while
            reading IFF ILBM images. A rare bug in the original
            Commodore IFF source. Fixed.
        E - Following serpentine(!) dither had a bug that might
            have caused a crash in Studio V2.11&2.12: Stucki,
            Jarvis and Sierra3. Again, only serpentine methods
            were affected. Fixed.
