I am using the Print RGB extension for Quark 4.04 and things are working fine
for me with CMYK and RGB imports. What you stated above is incorrect
according to the supplied PDF. The PDF file states that PrintRGB will output
RGB Tiffs without converting them and will not effect CMYK files. This part
of my workflow is working fine for me since I control all color conversions
with my output software, Onyx Postershop.
I have Quark 4.1, but decided to stick with 4.04 since I'm not experiencing
any problems to date. With v4.1 of Quark it seems to give the operator only
two choices for composite output, CMYK or RGB, I get documents at times that
have both RGB and CMYK tiffs.
If I choose CMYK composite in Quark 4.1 when postscripting does this then
convert my RGB files - I prefer it not - and if I choose RGB composite what
does Quark do with the CMYK tiffs, convert them to RGB? Quark CMS is turned
off.
My original post concerned what to do with DCS files that contain a spot
plate and how to handle them when printing composite postscript rather then
separations.

I did test a DCS file with a 5th plate in Quark 4.1 but got the same results,
the image dropped out when treated as a composite postscript.
Is my above method of merging the spot color my best solution?
