THE OFFSET PRINTING PROCESS
Offset continues to be the predominant printing process for small and larger run printing jobs due to its flexibility, its variability, the high quality standard that can be achieved by it, and its cost effectiveness.
Contrary to other printing processes, offset uses a printing form (printing plate) considered to be flat. The plates, specially treated by chemicals, are able to accept inks and repel water (hydrophobic) in the image areas and able to accept water (hydrophilic) in the non-image areas. To achieve a sharp separation of the printing areas from the non-printing ones of the plate, it is essential to use an aqueous damping solution in conjunction with the offset printing ink. The water used for this purpose as well as the employed damping solution additives must conform to certain specifications.
