Colour reproduction and pre-press technologies

Abstract

The various printing processes and types of equipment used in the decoration of metal packaging are described in earlier chapters together with a review of some of the materials used in these processes. However, preceding the printing process is a number of important stages that are often referred to as pre-press; these include graphic reproduction technologies. In the case of conventional printing processes, pre-press includes the various stages leading up to the manufacture of a printing plate whilst in the new evolving technologies, such as electrophotography for example, it involves the creation of data to drive the laser scanning heads that create the latent image on the photo-receptor.
