This disk contains Studio Professional V2.10. Version numbers
shown by the programs on this disk may differ and are only updated
in case the program itself was changed.
This file contain notes about changes made after printing the
manual. We also feel that it is your right to have the
information about changes made to previous versions:
------------------------------------------------------------------
Installation problems?
Please note that the Commodore installer sometimes shows problems
with various other sized system fonts. Temporarily switch back
your system to the default Topaz 8 font for installation, in case
the Installer doesn't show you all text in a proper format.
We had some (6) cases of bad devices/filesystems causing the
installer to crash during/after installation. Avoid these bad
devices/filesystems as they are likely to cause other crashes on
your system too. This warning is especialy for Emplant users. In
most cases you are still able to install Studio after booting from
an orig. Workbench disk. In this case, select "Expert" mode
during installation. After installation, you are required to
setup the Studio driver manualy by either using the Preset menu of
the installed driver preferences program.
------------------------------------------------------------------
DESKJET NOTES
Dear Deskjet 6xx/8xx (xx = 00, 60, 50, ...) user. WARNING: The
current drivers are able to print 600*600dpi in greyscale mode.
Please note that the printer is unable to print 600*600dpi in
color mode. Don't try to print color in 600dpi mode (Density 2 or
6 with the 600x600 option set in DeskPref/DeskPref4c) or you might
mess-up your printers output. The driver will automaticly print
in SuperGrey mode when trying to print 600x600dpi.
In order to print 600x600dpi, set the 600x600dpi gadget in
DeskPref/DeskPref4C. This will double the print resolution from
Density 1, 2 and 6. Use Density 2 or 6 for 600 dpi printing.
Deskjet 8xx users should NEVER use density 5 (600*300) dpi for
printing. This mode is not supported by the Deskjet 8xx family
and can currently only be used with the Deskjet 6xx family.
Deskjet 6xx and Deskjet 8xx should always enable the 600x600
gadget in the DeskPref 4C preference program. This will enlarge
the printable area for graphics. Please note that the printers do
have an unprintable margin of roughly 1.5 cm (1.2 cm plus 3 mm
tolerance because of mechanical reason). It also avoids printing
offsets between different graphic pages.
DeskPref4C offers two presets in the menu for Deskjet 6xx and 8xx
users. "Set I" adjusts the driver for 300dpi greyscale printing
and 300 dpi color using an Ordered dither method. "Set II" adjust
the driver for 600 dpi greyscale printing (Ordered dither) and 300
dpi color using the slower Blue Noise dither. Simply try out wich
one fits your needs (and paper!) best. Or make your own settings
starting with one of these two presets.
------------------------------------------------------------------
STYLUS COLOR NOTES
Please note that Studio does output very good ESC/P2 code. If
your Stylus Color printer shows stripes in the output, try
cleaning your print head several times. It's definitly not a
problem of Studio. We received several reports from users that
turned out to be problems with bad ink heads and mechanical
reasons.
So, clean your ink head several times as described in the printer
manual. In case this doesn't solve your problem, try using the PC
calibration tool that comes with the Stylus Color. We will try to
ship a similar calibration tool for Studio in the next upgrade if
possible.
And as a final note: please note that stripes in the output also
depend on the printing speed and the dither method used. Some
dither methods do show more banding than others. This is a
general effect on all ink jet printers.
As described later, improved Studio software for the Stylus Color
family is currently under development (mainly specialised output
modules and measured profiles offering superb color quality). We
hope to release this update within the next months and it is most
likely the first cause for an update notice sent to Studio users
since the release of V2.00.
------------------------------------------------------------------
Canon BJC and BJ
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).
Studio now offers several profiles for the Canon BJC 70 and BJ 30
printer. Users may also use the BJC 4000 profiles with minor
differences.
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 Cnaon 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.
The Canon BJC 4100 printer is already mentioned in the manual.
Please note that this printer is only announced in the US.
However, we will support this printer once it is sold. The BJC
4100 does not offer any dip-switches. However, the CanonBJ-EC
driver in Canon BJC 4000 mode will run fine with the printer right
out of the box. A setup program similar to the PC Windows version
is under development. So use the BJC 4000 software meanwhile -
wich runs fine on the BJC 4100.
------------------------------------------------------------------
LASER PRINTER
Lexmark Optra 1200 users can now enable a 1200dpi PJ-Language
setting. Additionaly setting the "Max Res" gadget to 1200 dpi
will allow you to print 1200dpi on the Lexmark laser printers.
Please note that PCL 5e does not define a 1200dpi resolution yet.
However, the Lexmark's implementation most likely will be used by
other 1200 dpi PCL printers in the future. So try it and if
doesn't work, write a letter!
------------------------------------------------------------------
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.
So what's the very near future (3 months)? Most important, we
will start releasing color profiles with measured values. These
profiles will finaly show the power of Studio's CMS. We will
start with new profiles for the Stylus Color family. If you think
the color in the output is not perfect now, than wait for these
new profiles ;-) Also you can expect further speed increases and
more functions combined with improvements to the user interface in
the very near future.
----
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 {\it
weak}\footnote{Weak means less black is used} non linear grey
component replacement function. 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:
VERSION
Returns the version of the Studio ARexx interface. Up to version
2.09 Studio returns 1 in PRTSTUDIO_RESULT. Version 2.10 and
higher returns 2.
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
01.11.94 V2 E - Release of the German (not English) version
07.11.94 V2.01 E - Serial number check failed on some
serial numbers (only affected 20 users with
serial #xxxxxxx9 and #xxxxxxx0).
E - Defining a custom dither in the driver
preference editors may lead to an endless loop.
(only affected color drivers).
E - Color output using density below 3 and
an error diffusion dither may lead to a crash.
21.11.94 V2.02 E - Printing a JPEG image from Studio with
histogram/clipping AND landscape function
enabled may caused a crash. All other image
formats were not affected.
28.11.94 V2.03 I - Release of the English version
I - Error buffer is initialised at margins,
avoiding stripes with strip-printing programs
19.12.94 V2.04 I - 40-50 percent speed increase while using
the printing programs Blue Noise dither methods.
26.01.95 V2.05 I - minor enhancement to the installation script
avoiding problems with bad system software
I - minor enhancement to the report program
C - Studio Gadgets are now ghosted at all places
when an error requesters appear.
I - New Mitsubishi monitor CIE data added.
20.02.95 V2.06 I - Canon BJC600e output module added.
I - CanonBJ-EC driver now supports 600e print modes.
I - minor improvements to installation.
27.02.95 V2.07 I - MAJOR speed improvements (2-3 times faster)
in the Studio printing program:
+ all dither routines are written in assembler.
(driver routines have always been in assembler)
+ Canon and Epson ESC/P2 output module now supports
double buffering with async. IO.
+ optimized printing with Workbench module
if image doesn't cover complete page.
E - IFF DEEP images sometimes didn't load
correctly (only when landscape/effect or
poster function was enabled).
E - Gamma correction of monitor values were done
after clipping/histogram. This resulted in a
too dark output with clipping/histogram and
CMS enabled.
E - Sierra3 and Sierra2 dither routines were swaped.
Selecting Sierra2 resulted in Sierra3...
E - A fault made it into the Stucki color binary dither
routine in V2.04. Ouups.
I - Canon BJC 70, BJ 30, BJ 200ex Extended mode
Workbench driver added.
I - Studio Extended Emulation output module added for
BJC70, BJ 30 and BJ 200ex
I - Canon BJC 70 CMS profiles added
I - 600x600dpi mode added to DeskDriver/DeskDriver4C
I - Laserjet 5P/5MP support added to LaserDriver/SetupPJL
C - Defining custom pages sizes for CanonBJ5-230 and
CanonBJ-EC changed.
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.
