The influencing factors of ink absorption performance of sublimation transfer paper(part one)

The ink absorption of paper refers to the ability of the paper surface to receive the transfer ink at the moment of imprinting, the ability of the paper surface to be wetted by the printing ink, the ability of the paper surface to absorb certain ink components, and the ability of the paper surface to fix and retain a uniform ink film. The comprehensive embodiment. Paper absorption ink is divided into two stages, one is the pressure infiltration stage: at the moment of printing press imprinting, depending on the printing pressure, part of the ink transferred to the surface of the paper, including pigments, binders, etc., is simultaneously pressed into the paper. In the pores. The second is the stage of free infiltration. This stage is from the paper leaving the embossing area until the ink is completely dry, mainly relying on the capillary action of the paper fibers to absorb the ink. At this stage, the absorption rate of the ink on the paper determines whether the printed matter has g...
