Computer to Plate Basics Explained 
In Europe and the US, Computer to Plate (CtP) seems to be a fast growing market. In some areas of the print market the majority of printers have already made the transition from traditional plate techniques to CtP. The reason why is easy to see: CtP gives almost instant colour register on the press, and there is no need to worry about stopping the press for removal of dust marks and scratches that sometimes would plague traditional film.
