Many of you may already be completely aware of this and I may be just
looking like a hayseed right now, but I put a stuffed file and PDF on my server
space for those who have to build or rebuild in Quark 4.xx and want to
append their palette to include Rich Black, Super Black and Stayaway
White that traps every time.
The Quark doc can be used to append into the color prefs of any
doc or better yet in the app prefs itself (append the color palette with
no document[s] open) and have it there everytime you make a new doc. The
PDF is a greatly magnified result of how (in this case) rich black and
stayaway white rasters out and shows the trap. Not as good perhaps as
the Agfa/Avantra preview, but you get the gist.
Quark link (about 4K) is here:
