In prepress, computer to plate (CTP) is a system in which electronic page information is used to process graphics and artwork direct onto a printing plate. There are many benefits with the CTP process:

• eliminates film and reduces processing chemicals and cleaning solutions
• use of digital proofing systems
• cost effective and increases productivity speed
• fingerprints the press for reprints with precision print values which reduces make ready and ink wastage

Other environmental initiatives:

• thermal direct (processless plates) eliminates the use of water and chemicals
• water recirculation units are available which is fitted to the plate processor and reduces water usage by 95%
