The National Standard for the Printing Industry Primarily Drafted by CHNSpec Has Been Officially Approved

Recently, the national standard Printing Technology—Color and Transparency of Four-Color Printing Inks—Part 2: Coldset Web Offset Printing (Plan No.: 20232426-T-421), led and primarily drafted by CHNSpec, has been officially approved and released. This standard is administered by the National Printing Standardization Technical Committee (TC170) and supervised by the National Press and Publication Administration (National Copyright Administration). Its implementation will inject critical momentum into the standardized and internationalized development of color quality control in China’s printing industry.

As a technical specification that is identical to the international standard ISO 2846-2:2007, this standard precisely focuses on the core indicators of color and transparency of four-color printing inks in coldset web offset printing scenarios. It successfully fills the gap in China’s seamless alignment between technical requirements in this segmented field and advanced international standards, helping elevate the industry’s technical level to international benchmarks.

Throughout the entire standard development process, CHNSpec fully leveraged its technical expertise and accumulated strengths in spectral measurement and colorimetric calculation, serving as a core technical support contributor. Drawing on many years of in-depth practice in the field of color measurement, the team deeply participated in the optimization of test methods for color uniformity and transparency tailored to the characteristics of coldset web offset inks. In particular, in key aspects such as measurement accuracy control and data repeatability verification, CHNSpec provided a large amount of detailed and reliable practical data, laying a solid foundation for the scientific rigor and practicality of the standard. CHNSpec worked closely with Shandong Taibao Information Technology Group Co., Ltd., Anhui Xinhua Printing Co., Ltd., Xi’an University of Technology, and other drafting organizations. Through multiple rounds of technical discussions, laboratory validation, and text revisions, all parties jointly promoted the continuous improvement of the standard content, ensuring that it not only meets real-world industry application needs but also maintains strict technical authority.
