makes good enough sense. i used ulano's QTX emulsion for the screens, knowing full well the resolution capabilities are limited on an ultra-fast emulsion. I mean to get a good emulsion for my exposure setup and will probably consult someone over to Ulano today or tomorrow. right now i am only holding a line weight of 0.3, positive and negative.

There is a downside to using the levels command, rather than a transfer function.
okay. i will focus on using the transfer function as opposed to the levels adjust. (something that is still somewhat of a mystery to me...)

i use both corel and photoshop. for the image above i output from corel with 55 lpi across the board and Jeff Proctor's CMYK angles 55, 22, 5, and 80, respectively. i think i'd like to try adobe's default screens for the next go, based on the info you had posted earlier in this thread about mathematical inconsistencies between the software and the RIP.

Also Fred-
just wondering if you've expirimented with other underbases for your process work besides a 110 "bulletproof" white... I saw someone post about a halftone underbase and thought about how much sweeter that could be...

thanks for the help and encouragement.
