1. INTRODUCTIONWeb-offset printing has shown strong growth in recent years because itimproves the competitive positions of both folding-carton and flexible-packagingconverters. For the carton printer, instead of four separate, low-speed operationsfrom roll to finished carton (sheeting, printing, die-cutting and stripping), theyare choosing higher s

Raw materials'for lithographic offset printing must meet, apartfrom viscosity and rheology,a number of requirémeñts related tothe printing process. The process is based on a chemicaldifference between image and non image areas (in contrast toprinting 'systems with a physical 'relief differentiation). Toobtain an the lithographic ink is in competiti
