Water-based sublimation ink, also known as water-based heat transfer ink, is to make low-energy, easily sublimated disperse dyes into digital printing ink, and then print on transfer paper.Through heating, it can produce images in the shortest time on exquisite porcelain, metal, silk, chemical fiber fabric and other materials. It is very suitable for personalized development of the market needs and environmental requirements.
Because water-based sublimation ink is water-based ink, it is mainly made of water-based resin, organic pigments, solvents and related additives by composite grinding maching. Water-based ink is especially suitable for packaging and printing products with strict hygienic conditions such as tobacco, wine, food, beverage, medicine, children's toys, etc.
The main difference between water-based ink and oil-based ink lies in the different solvents, one is water as solvent, the other is organic solvent as solvent.
The difference between the two kinds of ink is as follows:
1.Water-based ink is concocted by water-based resin, which is soluble in water and can be diluted by water. The advantages of water-based ink are that it does not need organic solvents, reduces solvent volatilization, prevents air pollution, does not affect human health, and is not easy to burn. It belongs to environmentally friendly ink. Oil-based ink and solvent-based ink, insoluble in water, can soluble in organic solvents, but these organic solvents will react with some substances in the air, causing pollution.
2.Water-based ink,is stability amd can make bright color. Cheap price, good adhesion after printing, fast dry and strong water resistance. Oil-based ink is characterized by high ink viscosity, fast dry, water resistance, softness and light resistance. When used, the ink is more economical and the cost is effectively saved.
3.Water-based ink is usually used in food, medicine, beverage and other industries, packaging printing industry is also widely used. Oil-based ink is mostly used for metal, plastic, wood, aluminum foil, carton and building materials.
4.Oil-based ink can be diluted by organic solvents, and printed on absorbent and non-absorbent surfaces. It is not easy to fade after printing. Water-based ink can not be diluted by organnic solvent.
