Data Compression Techniques

Data volumes relating to graphic images contained within an Electronic Prepress System are high, and this leads to the requirement for large amounts of mass storage and extended processing and telecommunication times. The following paper quantifies the data volumes required when various classes of graphic arts originals are digitized and stored within a Prepress System and describes in outline two specific techniques for reducing those data volumes by an order of magnitude.
