Q: CMYK-JPEG positive/negative problem
|

| Christian Westphalen 2005-05-25, 7:14 pm |
| Hi,
Photoshop supports the out-of standard CMYK-JPEG format and depending on
the version of PS itīs often rendered in third-party-applications as a
negative. I recommend to use EPS JPG-coded, but what i really would like
to know:
How can i decide, if i have to render the JPEG positive or negative? Is
it a decision based on the creator or is there another tag that i could
use for the decision?
Thanks in advance,
Christian Westphalen

Why? If you're using EPS files, odds are good your intentions are to
take them to press. Why bother with lossy compression that degrades
image quality? Anyone who's doing professional print production in this
day and age should be able to handle uncompressed files; hard drives and
RAM are cheap, cheap, cheap.

Itīs a question of bandwith, there are still some places where DSL is
not available and itīs "good enough" f.e. for newspaper print.

Moreover JPEG-encoded EPSFs may not separate properly from certain
applications (e.g. QuarkXPress) or on certain RIPs. Uncompressed files
are much more portable IME.

In that case, the files can be sent compressed but should probably be
uncompressed before placement and output; as someone else has already
mentioned, JPEG-compressed EPS files do not separate reliably.
