In the inkjet printing industry, the curing speed and quality of ink are crucial. Especially when using high-speed printing or special inks, the selection of the appropriate photoinitiator significantly affects the finish of the printed materials. Incorrect selection of photoinitiators can lead to poor ink curing and a decline in quality. Our photoinitiator light absorption wavelength chart allows for a comprehensive overview of the absorption wavelengths of various photoinitiators, supporting the selection of the optimal initiator. 【Application Scenarios】 - Inkjet printer manufacturers - Printing companies - Companies using UV-curable inks 【Benefits of Implementation】 - Improved print quality through optimal selection of photoinitiators - Optimization of ink curing time - Cost reduction
