What is the difference between inkjet printer ink and photo machine ink

一、 airbrush ink

Airbrush ink belongs to the oil-based ink. Also divided into solvent and weak solvent ink. Weak solvent ink and waterproof and sunscreen. The chemical composition of the inkjet ink consists of ink base and coloring agent, can be classified according to the coloring agent, and can be classified according to the ink base.

1, according to the colorant to divide the type of inkjet ink

a, dye ink: dye ink is the molecular level of the full dissolution of the formation of ink is a complete composite solution is not easy to plug the head: its water and UV resistance is weak, mainly for indoor spray painting.

b, pigment ink: pigment ink is also often called PIGMENT ink. It is a small solid particles ground into very fine particles dissolved in a special water-based solvent (containing polyol components), the formation of a gel-like suspension solution or called semi-solution, waterproof, UV protection, with UV protection supplies to do outdoor use.

2, according to the ink base divided into types of inkjet ink

a, water-based: according to its characteristics can be divided into solution-type ink, diffusion-type ink, micro-emulsion ink.

b, non-water-based: according to its characteristics can be divided into oil-based ink and solvent-based ink.

c, phase change type: according to its characteristics can be divided into liquid to gel and liquid to solid two types.

d, reactive: mainly UV-curable type and other general for printing on glass, rubber and other appendages.

Second, the portrait ink

Writing ink, also known as indoor ink, mainly with water-based ink, odorless and environmentally friendly, not waterproof and sunscreen. Indoor also divided into thermal foam and piezoelectric two kinds of ink.

Writing machine mainly two kinds, water-based and oil-based. Subdivision and divided into four-color machine and six-color machine with four colors is C (blue), M (red), Y (yellow), K (black), six-color machine and two more LM (light red), LC (light blue).

1, pigment ink: the advantage of good light resistance, the disadvantage is that the color is darker.

2, water-based dye ink: the advantage is that the color is bright, because it is made of water, evaporated water, there is no harm to the environment, more environmentally friendly, the disadvantage is that it is easy to fade, generally only used indoors.

3, water-based sublimation ink: the advantage is that it can be transferred to different media, not only on paper. Such as ceramics, glass, sand and gold film, silk and silver film, photo non-woven, cotton canvas, etc.

4, soluble ink: As the oil-soluble ink is made of pigment, the advantage is odorless, good light resistance; disadvantage is that it is expensive, and must be printed on the media with Xu layer.

5, solvent ink: because it is pigment-based, so the advantages of light resistance, good water resistance, and can be printed on any media. The disadvantage is that this ink itself with the oil base are flammable, is dangerous, there is a strong smell, there is a certain harm to the human body.

6, UV-curable ink: The advantage is that the ink itself does not contain volatile solvents, and after curing, light resistance, water resistance are very good, so it is very suitable for the printing industry; water-based programs are mainly users of indoor as well as textile printing; use water-based dyes or water-based pigment ink.

Now the domestic advertising photo machine can also use oil-based ink, but generally do not allow the use of water-based ink, or nozzle easy to burn out. With water-based ink can not use oil-based ink.

Simply put, the biggest difference between the inkjet ink and photo ink is as follows：

1, the ink itself: the inkjet belongs to the oil-based ink, while the photo belongs to the water-based ink.

2, ink features: spray ink waterproof and sunscreen, photo ink clarity.

3, ink use: inkjet ink is commonly used in large outdoor screen, portrait is often used for indoor screen spray painting.
