5101Re: Halftones and photopolymer
- Dec 17, 2005Ed
Actually, I'm just processing plates, I rarely use halftones for
letterpress work. I'm mainly hoping for some useful information to
teach folks who want halftones how to configure them properly. I've
gotten some very good responses offline but that doesn't exactly help
Can't imagine a four color halftone with photopolymer; sounds like a
registration nightmare, but I would agree with your instruction,
though to do it properly a lot of old school technique is required.
And while many folks know how to make wonderful photographs many do
not know how to configure them for print reproduction.
I've gotten a number of responses offlist--- In
