What is the difference between the ink used by ordinary pens and the ink used by cartoonists to draw cartoons?
It is the difference between dye ink and pigment ink: dye ink is completely dissolved at the molecular level and is a complete composite solution, and the probability of blocking the ink head is very small; Figuratively speaking, pigment ink is BLACKPINK. Of course, this is just a metaphor, which is not accurate enough. To be precise, it grinds solid pigments into very fine particles and dissolves them in special water solvents. It is a suspended solution or semi-solution, which has the same properties as the pigment of our printing and dyeing clothes.
