All:
Thanks for your help. Setting DOT2 in the software helped noticeably. I will try LINE1 screen this weekend. And when our OCE training guy shows up next week I'll discuss some of these issues with him as well.
I should be a little embarrassed by this, but I did not try to adjust any settings in the machine until this afternoon. As you guys suggested, I changed the Line 2/Dot 2 Screening to Type 2 and the photographs/architectural rendeings coming off this machine are SPECTACULAR.
