Implementation of Colorimetry in Measuring Color Quality in Graphic Products

Abstract

This study aims to initiate the application of colorimetry as a method of measuring color quality in graphic products. With the development of the printing industry, the need for color consistency is increasingly urgent, and colorimetry offers an objective solution in color quality control. The measurement method using the parameters L*, a*, and b* was carried out on various types of printed materials, including glossy and matte paper, to identify the effect of material type on color perception. The measurement results showed that the colorimetry method was able to detect small color variations, with an average delta E value of 1.9, which is still within the tolerance limit for industry standards. In addition, the study identified that production conditions, such as temperature and humidity, had a significant effect on color consistency. The implementation of colorimetry has proven effective in improving the quality and consistency of printed products, but also faces challenges in terms of cost, tool calibration, and the need for skilled operators. Recommendations for the application of colorimetry in the graphic industry include an integrated color monitoring system and increased control over production factors. This study is expected to contribute to improving color quality standards in graphic products, as well as strengthening the industry's position in meeting consumer expectations.
