Printing ink according to the plate type is mainly divided into relief ink, lithographic ink, gravure ink, screen printing ink four categories According to its own characteristics can be divided into two categories of water-based ink and oily ink So what is water - based ink and oil - based ink? What's the difference? Usually see a lot of books, albums and other paper printed matter are used what ink? 1.Water-based ink and oil-based ink concept Water-based ink Water-based ink is referred to as water ink, is a kind of water-soluble ink, flexible version of water-based ink is also known as liquid ink, it is mainly made of water-soluble resin, organic pigments, solvents and related additives by complex grinding processing. Oil-type Ink Oil-based Ink (Oil-type Ink), also known as oil-based ink or oil-based ink, is a kind of pigment particles dispersed in non-polar connectors and non-polar solvents in the ink. It is mainly composed of pigment particles, non-polar binders and non-polar solvents. 2.The difference between water-based ink and oil-based ink The biggest difference between water-based ink and oil-based ink is that the former can melt in water, and the latter can only melt in specific organic solvents.Therefore, water-based ink can be diluted with water, the benefit is no organic solvent, reduce solvent volatilization, can prevent air pollution, does not affect human health, not easy to burn, belongs to environmental protection ink. Oily ink can be diluted with organic solvent, can be absorbent surface and non-absorbent surface printing, printing is not easy to fade, the use of ink more economical, effective cost savings. In addition, oil-based ink also has environmental protection oil-based ink, no need to dissolve can be jet code. 3.the application of water-based ink and oil-based ink Application Water-based ink is characterized by low price, good adhesion after printing, quick drying, strong water resistance, coupled with it does not need organic solvents, especially received health requirements of the industry favor, such as especially suitable for tobacco, alcohol, food, beverages, drugs, children's toys and other strict sanitary conditions of packaging and printing products Oil-based ink is characterized by large ink viscosity, fast drying, water resistance, soft, light resistance is quite good, ink is more economical, effective cost saving. In addition, there are now environmental protection, so the application is also quite extensive, such as often used in books, albums and other paper substrates printing, in addition, there are metal, plastic, wood, aluminum foil, carton and building materials and other materials printing. Raw material of ink. Widely used in environmental water-based ink, flexo printing ink, UV gloss, water-based glazing oil. Whether it is printing or edible marking ink, or high-end paint such as car paint and refrigerator paint,Our company can provide this material Water-based acrylic emulsion  is a high-perfor...

Water - based ink is also known as water - based (oil) ink, referred to as ink.Water-based ink is made of water-soluble or water-dispersed polymer resin, colorant, surfactant and other related additives through chemical process and physical processing. Water - based ink containing a small amount of alcohol water as solvent, ink stability.Therefore, it is especially suitable for food, medicine and other packaging industries. Water-based ink can be cleaned with water, non-flammable, non-explosive, no adverse effects on the atmospheric environment and the health of workers, and no fire hazards caused by static electricity and flammable solvents, with production safety. Water-based ink is a new type of printing ink with high color concentration, no longer soluble, good gloss, strong printability, good leveling and high solid content.Water-based ink is easy to operate. In printing, only according to the demand in advance to add tap water allocation of good ink. In the printing process directly add a proper amount of new ink, do not need to add additional water solvent, can prevent the color of different shades. Water-based ink dry after the general no longer soluble in water. When printing, the printing plate must be immersed in the water-based ink to keep rotating at all times. Otherwise, the water-based ink on the printing plate will dry quickly, causing the plate roller to be blocked, resulting in the inability to print. In view of the increasing price of organic solvents caused by the depletion of petroleum resources, the cost of solvent ink production and environmental use will be increasing. The solvent of water-based ink mainly uses tap water, and because of the high concentration of water-based ink, gravure printing depth can be shallow. Therefore, from the cost point of view, although the price of water-based ink is high, its comprehensive use cost is estimated to save about 30% than solvent ink, and there are few concerns about residual toxicity of solvents on the surface of printing materials. Water-based ink has successfully explored the application of plastic intaglio printing, which is undoubtedly a good news for color printing and packaging factories.

The addition of wetting dispersant has obvious effect on the foam of some water-based ink.For example, polyacrylic acid wetting dispersants foam more than other types of wetting dispersants.Generally speaking, wetting dispersant foam with low dispersion capacity is also less. If diisobutyl sulfonate is based on disate, there is little foam at its content of 0.1-0.25%. The use of thickeners will make the defoaming work of high viscosity ink especially difficult, this type of ink has its own special defoaming agent.The drying time of ink film is closely related to the selection of defoamer. In the printing process, the ink film is required to dry quickly, so the defoaming agent with strong defoaming power should be selected in ink painting. Latex ink has a high pH value.Not good for controlling bubbles.Emulsion polymer is used as film forming agent in acrylic ink, usually the particle of emulsion is very fine, resulting in defoaming work is difficult.Pigment particles such as carbon black, phthalocyanine blue and phthalocyanine green organic pigments have a tendency to increase foam in water-based ink, which is also caused by the pigment particles are too fine, and defoaming is also difficult. Because many defoamer will affect the dispersion of pigment, pigment particles will adsorb defoamer particles, so the selection of defoamer, storage stability test must be carried out.The addition of filler in ink and wash also affects the existence of foam, for example, the use of silica instead of talc foam will increase. But this problem can be solved by increasing the amount of antifoaming agent.
