Re: Wrong colors when creating color AFP overlays

I wonder if it might work better if you limited the pallet to 256 colors?

Hi,

After spending nearly eight hours on this problem, i'm ready to give up.

I'm trying to create a color AFP overlay, which I can print to any
IPDS-enabled color printer which supports FS45.

The problem is that the colors in the AFP file I get are already wrong,
before I even upload the file to our iSeries (270, V5R4).

I try to generate the AFP using the IBM printer driver, supplied here:

http://www-1.ibm.com/support/dlsearch.wss?rs=95&apar=exclude&q=afp+drive
r+psd1*&dc=D430

(I'm using the Generic 600 dpi Printer driver)

I also tried the Infoprint Server gif2afp, tiff2afp, jpeg2afp commands.
These don't work at all.

There is some documentation on this issue:

https://www-912.ibm.com/s_dir/slkbase.NSF/acf2ee1e9d64b16e8625680b000203
89/f6ce4719a31214d68625710f005d87da?OpenDocument

It mentions printing from Word, which will generate RGB output, which
the printer driver will misinterpret. So I tried to use several
CMYK-Printing enabled applications, like Adobe Illustrator, Adobe
Photoshop and Adobe Acrobat.

Not one of them worked.

The problem is clearly visible in this screenshot:

document, on the right the AFP)

It also happens in the CMYK enabled illustrator in this screenshot:

However, printing the pure CMYK-colors works fine:

This is our Logo, in a CMYK EPS file:

I've systematically tried all settings available in the printer driver.
Some of them didn't work at all, but all of them created wrong colors.

Using the black and white mode works fine, of course. The problems only
there with color printing.

Anyone got any ideas on this? I've searched the web for hours, and tried
all possible settings. I didn't find any mentioning of people with the
same problem.

Thanks for any feedback in advance!
