provide anyone the results of this poll if you're interested. (Please
let me know whether or not I can use your name and/or your company name
in the posting of results)

    b) 100-500
    c) 500-1000
    d) 1000-5000
    e) 5000+

2) To make up for unreliable traps in SNMP our company does the
    a) Doesn't worry about it
    b) Polls for reliability and use traps
    c) Polls for reliability and ignores traps
    d) Sends redundant traps
    e) Sends traps over a TCP session
    f) Uses a sequential number within the traps to determine if any

1. Question Regarding In-Rip Trapping

I have been having some real problems with the trapping on the last
few editions of the product our company prints. I send a pagemaker
file with nothing but CMYK Tiffs and EPS files generated in
Illustrator and Freehand. The prepress has just recently (last seven
months or so) switched to a Scitex with in-rip trapping. The last job
they did for us was hideous; ugly white casts around the majority of
non-black text. The registration looked off by up to a point on some

Their head technician told me not to do *any* trapping from my end. I
was dubious to say the least. I usually work chokes on the text with
an overprint in both Illustrator and Freehand (the tiffs have always
printed very cleanly; no casts whatsoever). Our designs involve a lot
of text with drop shadow effects, or highlighted by an outlined text
block pasted in behind a solid text block. We use only process
colours, and now print at 133 lpi.

What I am wondering is (since the prepress we deal with seems very
confused and evasive about this subject) is there any point in my
placing trapping on all the text and lines from my end? Will the
in-rip trapping cancel what overprints I have set? Or do they not deal
well with EPS files, or EPS files in Pagemaker 6.5? When I did it
before manually (and ripped on their Agfa) the trapping was very
crisp. Should our company look into buying some inhouse software like
Trapwise, as opposed to dickering with chokes and spreads in
Illustrator/ Freehand? Or should the in-rip work well, and they are
just making errors from their end?

Any comments or input would be greatly appreciated.
