The Performance Of The Coated Ink-jet Ink Analysis And Research To Improve It

Prospects for the development of digital printing, has become the consensus of theprinting industry. In this context, the study of domestic digital printing water-based inkis especially important. The research on coated paper ink-jet ink aimed at breaking thebarriers of the imported digital printing ink, and lay a solid foundation for thedevelopment of domestic digital printing ink.Paper on the basis of preliminary studies gives a further improvement, mainly inthe apparent increase in color gamut and stability optimization, by replacing the dye,the dye compound and formulation improvements, inkjet ink on coated paper.Through the printing method of multi-Mexico Road characterization of onecolor, using Matlab software, the coated paper inkjet ink color management solutionswas designed, focusing on the chromaticity characteristics and color gamut of the newand improved coated paper ink-jet ink. Experiment to determine the best use of densitywithin the maximum density range, to make a colored wedge, measured athree-dimensional color gamut for coated paper inkjet ink. Select five kinds of existingdigital printing and offset printing standards, the results showed that, in addition tosmall3.5%than the HP’s four-color digital printing standard color gamut, compared tooffset printing standards in Japan and the United States, coated paper inkjet ink’s colorgamut volume number large1.0%and7.83%respectively, compared to normaloperation of the Heidelberg four-color offset printing color gamut, large3.86%. Which,due to the limitations of the yellow dye, the saturation of yellow ink is low, theremaining tri-color ink showed good saturation characteristics. The analysis shows thatthe new improved coated paper inkjet ink can meet the need for printed colorreproduction.Through stability test, anti-aging test, Physical and chemical testing of the inkthrough level by level heavy volume, stability testing of the ink before and after lowtemperature and heated to high temperatures storage, and fluency test of continuousprinting and intermittent printing, results show that further improved coated paperinkjet ink has good stability.
