illus trapping and overprint

[Shanavaz]

Never use multiply for any trapping operations. Just overprint the top colour. The habit of multiplying can be a disaster if any one of the overlaping colour is spot colour. Your rip will convert all multiplied areas into CMYK.

Ours doesn't. It maintains spot colors that have been multiplied over a process. I just wish the designers would get the clue that they shouldn't a screen of a spot color to print over a 4 color image. There are only so many screen angles people.

Thats always a tricky thing and not just for spot colors on images. What about this scenario:
Semi metallic backgrounds (image printing on a screen of white on silver substrate). Its the same thing, best thing would be to try and elimate a color out of the cmyk.

Open to any other suggestions...

I watched the demo movie and PowerTrapper looks great.
Are there any competitors to this product? just want to check them all before spending $6200.

(I see that Esko also makes Instant Trapper, but i would want the full features of Power Trapper.)

Heidelberg has a nice trapping plug-in for Acrobat.
