I have a new Mac running 10.5.6 to an old Viper Rip 1.9.2 (running on a Mac with OS9) then to an Agfa Accuset 1000 imagesetter. I've used special ppds available for 10.4.11 and earlier and they worked fine-the AGFA AccuSet 1000-A. Always got the proper line screen from Illustrator, any version. Now with the new computer running Leapard, my line screens are not what they are supposed to be. Any ppds available for this upgrade in operating system? This just won't do at all.....please help!
