PressPerCent is an ink key presetting solution for offset presses that runs on Macintosh computers. PressPerCent allows to improve make-ready times, reduce paper and ink waste. PressPerCent processes each page of job in either TIFF, EPS, PPF, PostScript or PDF input format and calculates appropriate settings for ink key zones. PressPerCent could be configured for any plate size and ink key zones. PressPerCent output could be viewed as graphics on computer screen, printed or saved as CIP4 Print Production Format file. PPF files could be used with new press control systems from major press manufacturers: Heidelberg, KBA, KOMORI, Man Roland and others. PressPerCent Pro has exactly same features as standard PressPerCent application, with additional support for automatic file processing of jobs placed in so-called ‘Hot Folders’. It allows to use PressPerCent as a part of workflow in printshops with larger volume of production.
