The Study on Color Reproduction of Fluorescent Inkjet Ink

At present, the fluorescent ink has been widely used in security printing and packaging, as well as the interior. However, in view of the fluorescent ink color control is still lack of perfect standard, even for basic information collection of fluorescent ink color piece have no standard test method, which hindered the development of fluorescent ink. In early, we have realized the fluorescent ink jet ink printing output. The paper makes a further study on the printing methods and color test methods of fluorescent inkjet ink. First, we design different ladder color patch and print proof, choose RF-5301PC and PR-655 for color block information acquisition and compare the test precision. Using self-developed dot coordinate software and dot trapping software (Photoshop) respectively print proofs, and analyze color reproduction ability of the two kinds. Finally, we explore the influence of different substrates on the color reproduction range of fluorescent ink. The experimental results show that the PR-655 is more accurate than the RF-5301PC. Since the ink layer for inkjet printing is thin, the dot trapping and dot coordinate have little difference with the same amount of ink output. The performance parameters of the paper have a significant effect on the color reproduction of the UV fluorescent inkjet ink.
