GB/T 19437-2004 in English

《GB/T 19437-2004印刷技术 印刷图像的光谱测量和色度计算》由TC170（全国印刷标准化技术委员会）归口，主管部门为国家新闻出版署(国家版权局)。
本标准建立了对平版、凸版、凹版和孔版等印刷方式的印刷图像进行反射与透射光谱测量和色度参数计算的方法。本标准不适用于三滤色片(三刺激值)色度计，虽然附录B、D、E、F和G可能涉及此类仪器。本标准适用于通过摄影、喷墨、热转移、扩散、静电照相、机械转英色粉(脱机打样)等技术得到的有限批量复制的彩色图像。本标准不涉及视频监视器发射光谱的测量，也不能代替适用于特殊应用需要的其他测量几何条件的规范要求，例如，印刷材料(油墨、纸张)的评价。

Scope

This standard establishes methods for measuring reflection and transmission spectra and calculating chromaticity parameters for printing images of lithographic, letterpress, gravure and stencil printing methods. This standard does not apply to three-filter (tristimulus value) colorimeters, although Appendices B, D, E, F and G may refer to such instruments. This standard applies to color images reproduced in limited batches by techniques such as photography, inkjet, thermal transfer, diffusion, electrophotography, mechanical transfer, toner (off-line proofing). This standard does not deal with the measurement of the emission spectrum of video monitors, nor does it replace the specification requirements for other measurement geometries that are suitable for special application needs, for example, the evaluation of printed materials (ink, paper).
