In color printing, how to rationally arrange the order of color overprinting is an important subject studied by process technicians. An important function of printing is to copy original manuscripts artistically, which requires printing workers to have a certain degree of artistic appreciation and the ability to master color changes. Improper color sequence arrangement may cause problems such as color shift, color mixing and reverse overprinting of printed products; scientific color sequence arrangement will make the color of printed products closer to the original, and even strengthen a certain color atmosphere, so that the level is clear, the dots are clear, and the overprinting is accurate. The colors are true, natural and harmonious.

Global Printing Ink Industry Analysis — 2026 The global printing and packaging sector is undergoing profound and rapid transformation driven by aggressive green manufacturing policies, continuous high-speed production line upgrades, and increasingly stringent international safety and environmental compliance standards. As two irreplaceable core ink materials supporting commercial printing and industrial packaging manufacturing across the globe, offset ink and flexo ink together occupy over 70% of the entire global printing ink market share, serving countless printing factories, packaging manufacturers, brand enterprises, and international procurement teams worldwide. For industry practitioners and global buyers, systematically distinguishing the essential differences between offset ink and flexo ink is no longer merely a basic technical understanding, but a critical strategic step in controlling overall production costs, stabilizing finished product quality, improving market competitiveness, and meeting global environmental certification and food safety standards. Although both ink types are developed for color rendering, pattern reproduction and surface decoration in printing processes, they possess fundamental differences in physical properties, core chemical formulations, printing adaptation principles, drying and curing mechanisms, industrial production efficiency, final printing quality, substrate compatibility, environmental protection performance, and mainstream application scenarios. This in-depth professional industry guide systematically sorts out the core distinctions between these two mainstream printing inks, combines the latest 2026 global printing industry development trends, and provides targeted, practical selection suggestions for global industrial users. The content helps enterprises effectively avoid material selection errors, reduce defective product rates and unnecessary production losses, and optimize overall printing and packaging solutions to adapt to diversified international market demands.

The ink you're looking for is called thermochromic ink. It's a special type of dye that changes color based on temperature.

Thermochromic ink is also called thermochromic ink, heat sensitive ink or temperature display ink.
