Classification And Characteristics Of Inkjet Printer Ink

Sep 03 , 2020

Inkjet ink is a special colored colloid whose function is to record patterns on substrates such as paper or light box cloth. The three main components of ink include colorants (pigments), crosslinking materials (resins) and solvents. The ink mixture including the solvent is spray-printed on the substrate. As the solvent evaporates, the crosslinking material firmly combines the colorant (pigment) with the substrate to form a pattern.



Classification of inkjet ink



Digital inkjet ink can be divided into water-based and solvent-based. According to the solvent, it can be divided into water-based and non-water-based inks. Water-based inks can be classified into pigment-based, dye-based, and sublimation inks according to color materials; non-water-based inks can be divided into oil-based pigment inks and solvent-based  Pigment Ink. From a chemical point of view, oil is also one of the solvents. We collectively refer to them as non-water-based inks. In addition, there is a UV-curable ink that is rarely mentioned in China. The ink of Inkjet Printers can be roughly divided into these 6 types.

Advantages and disadvantages of various inkjet inks




1. Water-based dye ink:



The advantage is that the color is bright, because it is made of water, evaporates the water, and has no harm to the environment, and is more environmentally friendly; the disadvantage is that it is easy to fade and is generally only used indoors.



2. Pigment ink:



The advantage is good light resistance; the disadvantage is that the color is relatively dark.



3. Water-based sublimation ink:



The advantage is that it can be transferred to different media, not just paper. Such as ceramics and glass. Many different media can be transferred; the disadvantage is that the operating procedures are more troublesome and the price is higher.



4. Oil-soluble ink:



Since the oil-soluble ink is made of pigments, it has the advantage of being odorless and good light resistance; the disadvantage is that it is expensive and must be printed on a coated medium.



5. Solvent ink:



Because it is pigmented, it has the advantages of good light resistance and water resistance, and it can be printed on any medium. The disadvantage is that the oil base used in this ink itself is flammable, dangerous, and has a strong smell, which is harmful to the human body.



6. Ultraviolet curing ink:



The advantage is that the ink itself does not contain volatile solvents, and after curing, it has good light resistance and water resistance, so it is very suitable for the printing industry; the disadvantage is that some of its monomers can easily cause some people’s problems before curing. Allergic reaction.
