Re: Wrong colors when creating color AFP overlays

Sorry that I haven't any other ideas, Lukas.

The colors don't look the way they should in the generated AFP file.
There's no "real" printer involved in that process, yet.

That was illustrated quite clearly on the screenshots linked in my
original mail. When I print the resulting AFP files, they look the same
as the AFP on the screen.

You mean it doesn't reproduce the colors you want, or that the AFP output does not match the original?

Tried that. But doesn't produce the right color.

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!
