printing from cinepaint

I was interested in using cinepaint for photo editing, but
I'm having 
trouble printing.

I followed the instructions here (more or less):

http://www.behrmann.name/cm
s/cinepaint/bildbearbeitung/cinepaint_ccorrection_1.3.html

The separation processes seems to be work OK, but the actual
printing 
produces something that looks like a negative.


I tried cinepaint-0.21 and cinepaint-0.22. I tried linking
against both 
gutenprint 5.0.0 and 5.1.0.

I tried a whole slew of things, among them using different
icc profiles, 
different printer drivers, printing to a file and uploading
to the 
printer correctly to no avail.

Any ideas on what's going on?


Thanks!

The description is for 0.21, and printing itself did not
change since.

This could be possibly by exchanging RGB against CMYK.
Anyway it seems to 
be a bug.

At least 5.0.0 should work.

Some questions:
A. Is the second image, the CMYK image, looking right? 
B. Is the preview in the second print dialog right?
C. How does a print of the RGB/CMYK image behave, while
setting the first 
   print dialogs "Direct printing" option to RGB
or CMYK? Does this manual 
   setting conform to the images colour space?

Which hardware platform do you use, ppc or intel?

Thanks for the response.

Yes.

Yes, always.

So If I set the colorspace to rgb and I direct print to rgb,
that looks 
OK.  That's not using the printers color profile, though.

Setting the colorspace to CMYK and printing to CMYK doesn't
work.

For what it's worth, the output postscript seems to be 
_always_ rgb.

What part of the code (or what library) is responsible for
outputing the 
postscript?  I could try to step though it to see what's
going on, but 
it's hard to know where to begin.

The postscript code lays in the Gutenprint driver. I'd think
it is not 
well tested. The CinePaint part is only about the colour
conversion and 
expects you to run basically with native output not PDF/PS.

So to create a CMYK Postscript file is not possible with
this bug.
Alternatives are TIFF, eighter save the separated image as
such or use the 
Save Tiff button in the first print dialog. Or use a native
device 
driver. For Postscript currently bypass colour management
with the Direct 
print option.

If you need absolutely colour management in a Postscript,
you'd have to 
convert to Cmyk, 
than back to RGB, best sRGB, and 
print without colour management as Postscript.

I filled a bugreport to Gutenprint about the Postscript
output.

Robert Krawitz informed me that cmyk postscript will be
written correctly 
in version 5.1.2. Unfortunedly we need to do something with
our print 
dialog as it is not longer part of the Gutenprint package
since 5.1.x

Does this mean I have to wait a while to use cinepaint from
printing? Is
it possible to print via some other software? (an article I
read
mentioned Scribus).

If you want to print over a postscript file you'd eighter
have to patch or 
to wait.

Anyway, as long as your printer is localy connected and
supported by 
Gutenprint, I would recommend to manage the print file
generation in 
CinePaint and avoid postscript at all. Thus, Gutenprint
renders the print 
file from up to 16-bit data source in CinePaint itself with
more control.

CinePaint  ->  Gutenprint (printer language file rendered
from 16-bit)  -> 
spooling (CUPS/Lprng)  ->  
(local) supported print device


Using postscript adds an intermediate step with 8-bit
precission. Then 
the rendering into the print language happens after
spooling. You can do 
such in Scribus. Scribus has as well considerable good PDF
output.

CinePaint  ->  Gutenprint( Postscript 8-bit )  ->  
spooling with CUPS / transport with DVD  ->  
remote ripping (print file rendering)  ->  whatever print
device

I'm really sorry, it seems I misunderstood. I thought you
were
responding to an earlier email of mine in this thread. I'm
having
trouble getting Cinepaint 0.2.2 to compile. (The Ubuntu
package does not
have printing compiled in for some reason, and so far no
response from
them.) Below is my email from previously:

On ubuntu, gutenprintui seems to be called gutenprintui2, so
I created a

the latest

gutenprintui2.pc
lrwxrwxrwx 1 root root  16 2007-06-10 15:56 gutenprintui.pc
->
gutenprintui2.pc


Any suggestions?

thanks again, David.
