The Characterization of Web Offset Equipment Based on the Measurement of Chromaticity

Article Preview

Abstract:

t would be a large effort to use traditional methods of calibration procedures for Web Offset Press equipments. In this paper we proposed a convenient process calibration, which will not only guarantee the product quality meeting the ISO standards, but also save financial and material resources. Firstly, the measurements for determining the best ink thickness in Web Offset Press are discussed. The chromaticity values on solid fields with corresponding combination of paper and ink required by ISO Standards were achieved. Through a optimization process for gray balance, the printed tone values were adjusted to meet the requirements of ISO Standards. Finally several standardized test targets on sampled sheets ware measured, then the ICC profiles were created. This paper proposed an innovative process calibration, therefor using methods of chromaticity measurement, characterization of Web Offset Press can be put to effect to optimize printing processes.
