摘要
GRACoL 7是商业胶版印刷检测方法的新规范,是实施国际胶印印刷标准ISO 12647-2的基本要求,它针对CTP为基础的商业印刷流程,设定灰平衡、中性印刷密度曲线、亮度等概念的定义和测试方法,最终获得准确的数据,依此调整CTP制版机或照排机的RIP输出校正曲线,从而在保证系统重复性工作基础上,改善印刷品的阶调和彩色再现质量。本文对此作系统介绍。
GRACoL 7 is a new standard of testing methods applied in commercial offset printing businesses and also the requisites for implementing ISO 12647-2 for offset printing;aimed at the printing process flow based on CTP,it defines a series of new concepts and testing methods capable of yielding accurate data for adjusting the output curve of RIP of CTP or phototypesetting printing plate making equipment thus improving the image gradation and color rendition of printed matter on the basis of high system repeatability..
