PressPerCent started out more than 10 years ago as a simple ink key pre-setting software tool — a popular subject at the time when press manufacturers and printers were searching for less expensive, space-saving solutions to replace hardware plate scanners. Since then PressPerCent evolved to include more features the customers and OEM partners required such as support for the job format of virtually every press type and model, total ink calculations, spot color preview, automatic job processing and flexible press configurations.
Made for the graphic arts industry standard Apple Macintosh computers, PressPerCent evolved with the Mac OS operating systems. The application that once ran under classic Mac OS 8 and was closely integrated with the Adobe Acrobat package now takes advantage of Mac OS X built-in PostScript conversion and PDF rendering features. The current version is a universal binary application that works with Mac OS X 10.5 (‘Leopard’), 10.6 (‘Snow Leopard’) and 10.7 (‘Lion’) system versions (a separate build for Mac OS X 10.4 (‘Tiger’) is also available).
