HPChrome v1
(Unregistered Version)
HPChrome works on any Atari ST, with a H-P DeskJet 500C colour
printer, or with a standard DeskJet, DeskJet Plus or DeskJet 500
fitted with the Colour Kit.
HPChrome prints 16-colour picture files in DEGAS (normal or
compressed) and NEO formats. It offers a choice of size and
position on the page, with accuracy to 0.003in (0.08mm). Page
layout can be either Portrait (upright) or Landscape (sideways).
The whole image, or just a section of it, can be printed at Draft,
Normal, or Best quality. Colour-correction can be applied to
compensate for the differences between screen and paper colours.
What you need
=============
Any Atari ST computer (512K RAM upwards, colour or mono).
Hewlett-Packard DeskJet, DeskJet Plus, or DeskJet 500 printer,
with colour kit,
- or -
Hewlett-Packard DeskJet 500C, with tri-colour ink cartridge, H-P
part number HP51625A.
HPChrome runs in High resolution (on an Atari mono monitor) or
Medium or Low resolution (on a colour monitor or TV). To make use
of all the features, please use either High or Low resolution.
What you get
============
*HPCHROME.PRG - the program
*CONVERT.BIN - colour picture conversion module
*HPCHROME.TXT - the manual (this file)
The file CONVERT.BIN converts colour pics to mono so that they can
be viewed on an Atari mono monitor. All files are needed for the
program to run (this is to prevent distribution of incomplete or
modified copies, and does not apply to the registered version).
Shareware
=========
HPChrome is SHAREWARE. It is NOT FREE.
However, you are welcome to test and evaluate HPChrome v1 free of
charge. This version can also be freely distributed, subject to
the normal shareware distribution practices.
If you find HPChrome a valuable addition to your collection of
software then please send £5.00 to Rufus Developments. You will
then be registered as a user, and will receive the following
additional benefits:
(1) Registered version of the program, without the 'shareware
nags' that are built into this version.
(2) Printed fully illustrated manual, giving full instructions,
explanation of all features and options, and hints and tips.
(3) Desk accessory version, for use within DEGAS Elite, allowing
you to print your art creations without the need to save your work
or quit the DEGAS Elite program.
(4) JETALOG, a picture cataloguing program, to print 'thumbnails'
of your DEGAS and NEO pics, up to 15 per page, for loose leaf
binding.
(5) Technical support (if needed) and updates (as available) of
HPChrome. Support and updates are ONLY available to registered
users.
(6) Your money back! We are currently working on a complete
revision of HPChrome, an entirely new program, with full GEM event
driven user interface, able to print file types including Tiny,
GEM .IMG, Spectrum 512, and GIF. As a registered user of HPChrome
you will receive a £5.00 discount on the purchase price of its
successor! What a deal.
Colour Kit
==========
On the DeskJet 500C, full colour output uses the Hewlett-Packard
Tri-Colour Cartridge, which contains Cyan, Magenta and Yellow ink.
For other DeskJet models, the Colour Kit converts any DeskJet,
DeskJet Plus or DeskJet 500 printer into a full colour printer,
creating output of the same quality as the new DeskJet 500C - or
better!
The Colour Kit consists of ink cartridge refills in Yellow, Cyan
(blue), and Magenta (red), with which you can refill your empty
black ink cartridges. Cleaning solvent, to remove all traces of
black ink from the empties, is included.
To print in full colour, you simply use HPChrome with the
appropriate printer option. When prompted, change cartridges and
re-insert the paper. Yellow, Cyan (blue), Magenta (red), and
Black are printed on separate passes through the printer.
When used with the Colour Kit, but not with the DeskJet 500C,
HPChrome includes a Black ink pass. Black and other dark areas in
your picture will be printed in a more solid, monochromatic black
than is possible with the DeskJet 500C (which creates black by
combining Cyan, Magenta and Yellow inks).
We use and recommend the Inkmun Colour Kit, distributed in the UK
by System Insight. However, other brands of Colour Kit may also
be available. For further information, please contact your local
computer dealer, or:

============
Shingling and Depletion
Applicable to the DeskJet 500C only. Normally determined by the
Quality setting (Draft/Normal/Best). Depletion removes dots from
the printed image to reduce ink coverage. Shingling prints the
image in narrower stripes to avoid 'banding'.

in one pass, with data compression.
DeskJet Plus, DeskJet 500 (with Colour Kit) - prints the page in
four passes (yellow, cyan, magenta, black), with data compression.
