What will affect the absorption capacity of sublimation paper ink?

Effect of ink viscosity on absorption properties of sublimation transfer paper.

The image of the sublimation paper coating results in ink absorption not only related to the structure of the paper, but also to the viscosity of the ink itself. If the viscosity of the ink is too small and the penetration is strong, it is easy to penetrate the paper to produce a dim phenomenon; if the viscosity of the ink is too large and the penetration is weak, it is easy to accumulate on the surface of the paper accumulation phenomenon. Both enthalpy and accumulated ink can have a serious impact on the transfer effect of the product and should be prevented during the production process. Specifically, to ensure print quality of the pattern, process parameters for printing pressure, temperature and time can be combined with reasonable ink viscosity.

Effect of paper surface coating on ink absorption performance of dye sublimation transfer paper

Since the production process of the dye-sublimation transfer paper is subjected to a high temperature environment, the strength properties of the paper are greatly reduced. Therefore, it is necessary to increase the speed of inkjet printing and drying, and to shorten the time in which the paper stays in a high temperature environment to maintain sublimation as much as possible. The strength properties of the transfer paper meet the requirements of the product. This puts higher demands on the ink absorbing performance of the paper. Under the condition of ensuring a certain amount of ink absorption, it is necessary to improve the ink absorbing performance of the paper and increase the ink absorbing speed of the paper.

To this end, a layer of paint is applied to the surface of the paper as a coating to achieve rapid ink absorption. In order to meet the requirements of the national environmental protection policy, most of the inks used to produce sublimation paper are water-based inks. The ink components are mainly alcohols and poly-amides. In order to ensure the quality of the transfer pattern, it is required that the surface coating does not contain a component which can react with the ink used, and the surface coating of the coating is usually made of silicone or polyvinyl acid.
