ADOBE SCREENREADY POSTSCRIPT

Font Substitution
The substitution font is Tekton MM.  If your computer doesn't already have it, ScreenReady PostScript installs the PostScript font in your System Fonts folder.

Memory requirements
6 MB will allow you to process EPS files up to 100 x100 pixels
8 MB will allow you to process EPS files up to 640 x480 pixels

ScreenReady PostScript requires 1 MB free on your startup volume, but it's a good idea to have 5–10 MB free.

We recommend that you turn virtual memory off if you are running ScreenReady PostScript on a 68K Macintosh.  Many operations are very slow with virtual memory on, including starting up, changing the render cache, and processing files.

Folders
By default, no input or output folders are set up.  Choose “Set File to Render” from the File menu and select an EPS file to get started.

ScreenReady Log File
The “ScreenReady Log” is not visible by default.  To bring it to the front, choose it from the Windows menu or press Command-L.  This file is saved incrementally as you process files— you never need to save it.  You will want to clear the log periodically because it only records up to 1000 items.  At any time (when the log window is in front) you may save a copy (on the File menu).  Log files are read-only, but you may save a copy as text (same menu item, check “Save as plain text” in the dialog box).

When a log is saved as text, it is formatted as a SimpleText file.  If it is bigger than 32K, SimpleText will not open it, but most other word processing applications will.  Note that in SimpleText the columns will not line up vertically, but you may open the file in most word processing or spreadsheet programs to format it as a table.  

PostScript Cache
The PostScript interpreter uses this amount of memory while processing files.  If it needs more memory, it will use some free hard disk space on your startup volume.  If you notice the “Startup Disk free space” shown in the main window diminish while you render a file, you can get better performance by increasing the PostScript cache.

Render Cache
This cache is used to store each band of the image as it is being rasterized.  When this is larger, EPS files will process faster with less overhead (ScreenReady PostScript may not have to use the PostScript cache or disk space as much).  

Standard Macintosh Patterns
Dot patterns are processed into a solid color.  If the EPS file uses standard Macintosh patterns, they may appear as a solid color instead of the pattern.

Adobe PageMaker and Color Images
Adobe PageMaker 5.0 and earlier saves images in EPS files according to the color setting of your current printer device.  If you find color TIFF files being rendered in grayscale, resave your EPS file in PageMaker with a color PPD selected.

CMYK Conversions
Note that a color shift may occur when converting CMYK images to RGB.  You will get more predictable results if you save your EPS file in RGB format before converting.

Errors that may appear in the ScreenReady Log
The following are error messages that might appear in the ScreenReady Log file while converting, along with more detailed information and solutions:

render cache too small
The render cache is too small for an image of this size—use the Render Cache Worksheet in the Preferences dialog to calculate a new size.  When in doubt, increase the cache size one level.

increase PostScript cache
Increase the PostScript cache in the Preferences dialog.

out of memory
There is not enough RAM for an image of this size (smaller images may work).  Increase the application partition or decrease the caches (in Preferences).

disk is full
There is not enough space to save a PICT file on the destination volume.

not an EPS file
The file that was processed had a missing or invalid EPS header.

job canceled by user
Processing was canceled (Command-period or Stop was pressed).

name conflict – job skipped
“Prompt” was selected in the “if name already exists” popup menu, and when the dialog came up, you selected “Skip this file”.

image too wide – max image width is 4096
The maximum image size that can be rendered is 4096 x 4096 pixels.

one or more items not logged
Over 1000 items have been logged.  You should clear the log file.

PostScript error
The PostScript interpreter encountered an error.  An “.out” file is created and saved in the destination folder where the PICT file would have been saved (see below).

Errors that may appear in  the  “.out”  file for a particular job
The following are messages that may appear in an ".out" file following a PostScript error, along with more detailed information and solutions:

%%Error: limitcheck
%%Error: vm error
%%Error: MaxDisplayList, MaxSourceList, or disk space too small
The above error messages indicate that the PostScript cache is too small and/or there is not enough space on your startup volume.  It is not unusual for a complex file to require 10 MB of disk space or PostScript cache memory.

%%Error: Offending Command
An offending command usually indicates that there is a problem with your EPS file.  Either the file is damaged or some required resources were not saved with the file.  If you have this problem, try re-exporting the EPS file from the application that created it.

ADOBE SCREENREADY QUICKDRAW

Deferred Rendering
ScreenReady QuickDraw works in two steps. During the printing process it creates a spool file in a folder named “ScreenReady” in the Preferences folder. Then it launches the ScreenReady Monitor to process the spool file into the output image files. If there is insufficient memory for the ScreenReady Monitor to launch, these spool files accumulate in the ScreenReady folder. The next time the ScreenReady Monitor is successfully launched, it will process all the accumulated spool files, possibly in an order different from that in which they were created. In low-memory conditions, you can launch the ScreenReady Monitor by closing as many applications as possible, and then double-clicking on the ScreenReady Monitor's icon.

Screenready Quickdraw And Memory
ScreenReady QuickDraw works best when at least 6MB of RAM are available after starting up the application you will be printing from. Available RAM can be examined by selecting "About This Macintosh…" from the Finder's Apple menu and looking at the number for "Largest Unused Block." With less than 6MB of RAM available, ScreenReady QuickDraw will work more slowly. With less than 3MB of RAM available, there will not be enough memory for the ScreenReady Monitor to launch and you will have to quit applications and launch it directly (as described above). With around 1MB of RAM or less available, some documents will not print at all and you will receive an alert. If this happens, you will need to make more memory available either by closing applications or by turning off some extensions and restarting your computer.

For improved performance on machines with lots of memory, change the "Preferred size" setting for the ScreenReady Monitor to more than 6MB. Do this by selecting the ScreenReady Monitor from the Finder, choosing Get Info, and editing the "Preferred size" box to something larger than 6000K.

Changing Antialiasing Settings
For some documents with some applications, the first print job after checking or unchecking the "Antialiasing" checkbox may yield incorrect results. Symptoms include incorrectly scaled images, and graphical elements that are not antialiased when they should be. If you change the state of the "Antialiasing" checkbox and receive results that are not what you expect, try printing a second time.

Don't Save To The Move&Rename Folder
A folder called "Move&Rename" will occasionally be visible in the dialog for selecting the output folder. This folder is created by the system and is normally invisible. Files saved to this folder will not be accessible and will be deleted by the system.

Must Close The Chooser After Selecting Screenready
After selecting ScreenReady from the Chooser, you must close the Chooser before ScreenReady becomes active. The "Page Setup" and "Print" dialogs will not appear with the Chooser still open.

Using Screenready Quickdraw With Adobe Acrobat
When printing from Adobe Acrobat Exchange or Adobe Acrobat Reader, ScreenReady QuickDraw will rotate the pages by 90 degrees if the orientation of the output images (as set in Page Setup) does not match the orientation of the document. For example, if a document is taller than it is wide but is to be rendered to an image size that is wider than it is tall, ScreenReady QuickDraw will rotate the image. To prevent rotation, make sure that the output size set in Page Setup matches the size of the document.

Using Screenready Quickdraw With QuarkXPress
When using ScreenReady QuickDraw with QuarkXPress 3.2, the controls that QuarkXPress adds to the bottom of the Print dialog are inactive. This problem does not occur when using ScreenReady QuickDraw with QuarkXPress 3.31.

Using Screenready Quickdraw With Microsoft Excel 5.0
When printing a multi-sheet workbook from Excel 5.0 using the "Entire Workbook" option, ScreenReady QuickDraw will place files from some sheets in the wrong place and give them the wrong base name. To prevent this from happening, print each sheet of a multi-sheet workbook separately.
