Are you really using transparencies?  That should be media=3DMEDIA_PLAI=
N for
plain paper.

> printmode=3DPRINT_MODE_8_CMYK

This is causing the problem.  You are using 8 bits or 256 colors to
represent all possible colors.  While this might be okay for saving on
memory usage, it is not a good representation of the best that the omni=

driver can print.  You should be using printmode=3DPRINT_MODE_24_CMYK. =
 This
will use 24 bits and will allow 16 million colors.
As for what is causing your problem, it is the 8 bit color mode.  If yo=
u
switch to 24 then it will work.

> dither=3Ddither=3DDITHER_LEVEL

This is the worst dither mode available.  I should remove it from the o=
mni
driver.  Also, the double dither=3D is odd.  You should be using a diff=
usion
dither.  For example, dither=3DDITHER_STUCKI_DIFFUSION.  Perhaps the do=
uble
dither=3D is causing no change to occur and you will use the default of=

Stucki.

Can you send me a copy of the ppd file that you are using?  It should b=
e
located in /etc/cups/ppd/PRINTERNAME.ppd where PRINTERNAME is the name =
of
the CUPS printer.

A skilled user could edit that file to correct the mistakes.

What is the value of *OmniJobProperties in that file?  The *DefaultDith=
er
and *DefaultMedia should be altered as well.
