Embodiment Construction
[0011] Such as figure 1 As shown, the present invention is realized in this way, and it is characterized in that the emulsified ink 2 and the original ink 1 are respectively placed above the polyester base 3 with two rectangular frames, and the polyester base 3 is cushioned with For paper 4, evenly scrape emulsified ink 2 and original ink 1 into the rectangular frame from top to bottom, remove the polyester film base 3, leave ink color blocks on paper 4, put the ink color blocks into a After 20 minutes in the oven, cover the scraping paper on the ink color block, use a mechanical constant force on each ink color block in the same direction for ten times, lift the scraping paper, and observe the sticking or dirt on the scraping paper Use a colorimeter to judge ink viscousness, and compare and judge the change of drying performance of several pieces of ink when one of the condition variables is changed.
