Is UV ink oil based or water based, what is UV ink ink

UV inks are neither oil-based nor water-based.

Generally speaking, oil-based and water-based are based on the dispersion medium of ink, and simply put, oil-based ink is to disperse pigments in oil, such as mineral oil.

Vegetable oil, etc., the ink fixes the pigment on the medium through the penetration and evaporation of oil on the printing medium; Water-based ink uses water as the dispersion medium, and the ink fixes the pigment on the medium through the penetration and evaporation of water on the printing medium.

Oil-based and water-based inks have different dispersion media, so the dilution and cleaning media are also different. Oil can usually only be diluted and cleaned with solvents, water-based ink can be diluted and cleaned with water, we know that the decomposition of grease and ** is more troublesome, so water-based ink is more environmentally friendly.

Both oil-based and water-based inks need to be dried or natural to achieve a dry surface.

On the outside, UV ink is similar to oil-based ink, but the use and curing process is completely different.

UV inks, on the other hand, use a different principle, i.e., light-curing resins.

It is a dispersant that is irradiated with UV light energy to cause a chemical reaction.

Solidify the resin into a film. UV ink adheres to the printing medium by the adhesion of resin, and can form a film even if it does not penetrate, so it can be printed on metal, glass, ceramics and other materials. UV ink cures for a short time and does not volatilize solvent substances, so it is also an environmentally friendly and harmless ink.

But light-solid resin.

The decomposition and ** are also big problems, so UV ink is not 100% environmentally friendly ink.

Since we are talking about solvent-based inks, we are dispersants or diluents that use solvents as dyes or pigments.

The solvents used are usually very volatile in order to shorten the drying time of the ink. The problem is that solvents usually have a strong smell and are sometimes harmful to the human body and the environment, so solvent-based inks are not environmentally friendly inks, and it is necessary to pay attention to maintaining the ventilation and human protection of the working environment when using them.

UV inks are neither oil-based nor water-based.

UV ink and co-solvent ink determine their respective application methods and application fields due to their own essential characteristics. Because UV ink can be used together with white ink, many manufacturers can print some beautiful relief effects, which is to first use white ink to pile up with relief effect, and then use color UV ink to print again to achieve the relief effect. The weak solvent cannot be mixed with white ink, so there is no way to print the embossing effect.

In addition, due to the weakly soluble ink, many materials need to be coated when printing, and the printed products that have not been coated are easy to fade; UV ink can be directly used to print many materials, without any coating treatment, simple, convenient and solid.

UV ink is oil-based, not water-based.

UV ink is a kind of LED light emitting ultraviolet rays for fixed phone patterns, the ink itself contains a small amount of toxicity, can not enter the mouth, nose, eyes.

Neither is UV ink, a quick-drying, chemically formulated ink that is cured by ultraviolet light.

1. The characteristics are different.

The characteristics of ordinary ink: it has a certain fluidity, and meets the properties required by various printing processes, and can be quickly dried on the printed matter, and the dried ink film should have the corresponding resistance to various water, acid, alkali, light, rub, and wear.

The characteristics of UV ink: bright color (except for special circumstances), good printability, suitable curing and drying rate. At the same time, it has good adhesion, and has the characteristics of wear resistance, corrosion resistance, weather resistance and so on.

2. Different classifications.

Classification of ordinary inks: Inks have different properties depending on the binder used. There are mainly resin inks, solvent-based inks, water-based inks and UV-curing inks.

The use of organic solvents as ink binders has a negative impact on the environment. In order to make the ink meet the requirements of environmental protection, environmentally friendly materials should be used as the binder of the ink. Environmentally friendly inks mainly include water-based ink, UV ink, water-based UV ink and some alcohol-soluble inks.

Classification of UV inks:

1) Classification of printing technology: UV offset printing ink, UV screen printing ink, UV pad printing ink, UV water-based inkjet ink.

2) Application field classification: UV printing iron ink, UV metal ink, UV glass ink, UV plastic ink, UV circuit plate ink, UV photosensitive ink.

3) Artistic effect ink: UV ink can show a unique texture effect on the print due to the curing characteristics of UV ink, which is not available in other curing inks. Foaming ink, ice flower ink, hammer ink, crack ink, crystal ink, varnish, wrinkle ink, etc.

3. The application is different.

1. Application of ordinary ink: widely used in packaging, newspapers, commercial printing, etc.

2. Application of UV ink: With the development of UV technology, the combination of luminescent powder and UV ink to prepare UV luminescent ink has been gradually adopted by the majority of oak dust printing manufacturers, especially in the production of luminous signs, the use of UV luminescent ink instead of thermosetting luminescent ink has considerable advantages. The printing of UV luminescent inks using screen printing technology is a common method for preparing luminescent signs.

The main differences between UV ink and ordinary ink are as follows:

Drying speed: UV ink dries fast because it dries by ultraviolet light, while ordinary ink needs air drying, so it takes a long time to dry imitation ink.

Quality: UV ink has a harder texture and brighter color after curing, and it is not easy to fade, while ordinary ink is easy to fade.

Environmental protection: UV ink does not contain pollutants and is more environmentally friendly; Whereas, ordinary inks contain toxic substances that are not good for the environment.

Applications: UV ink is mainly used in printed electronic products, packaging and other fields; The general bypass ink is suitable for printing and brushing paper, albums and other fields.

UV ink is very different from ordinary ink. UV ink is irradiated by special ultraviolet light, which has the advantages of digging and anti-water-soluble, abrasion resistance, good air permeability, and can better fit the surface of the object. Ordinary inks do not have these advantages.

Good evening, UV ink composition is relatively simple, mainly with ultraviolet light-triggered photosensitive acrylate, mineral pigment particles and leveling additives three compositions, the main solvent is liquid resin is also cured into a hard coating of the functional acrylate monomer, mineral particles for the chromogenic material is generally common CMYK four colors, leveling additives are used to adjust the viscosity, adhesion and drying speed of inkjet. The main types of acrylates commonly used in UV inks are as follows, please refer to (UV ink is actually an ordinary solvent-based pigment ink, and the co-solvent is replaced with a photosensitive monomer, which is generally 1-3 functional acrylates, which are low cost and have good curing performance).

What is the chemical composition of UV ink: there are a lot of this, and there are more than ten kinds of them.

Ink is a combination of solvent and colorant. Therefore, ink can be roughly divided into water-based ink, solvent-based ink and UV ink according to its main components, that is, ultraviolet curing ink.

Water-based ink has no pollution, Shanbi is colorful, but the weather resistance is poor, indoor products are water-based ink, mainly used in paper and various fibers, that is, cloth as the substrate, coated media.

The main component of solvent-based ink is organic solvent, compared with water-based ink, solvent-based ink can be printed directly on uncoated media, and the printing cost is low. However, solvent-based inks contain VOC volatiles, which pollute the environment, and the pungent smell of solvent-based inks can also cause damage to the human body. Solvent-based inks are generally used in advertising and industrial fields.

At present, the concept of co-solvent ink is proposed, and the biggest change of co-solvent ink is the friendliness of the environment, which is mainly reflected in the reduction of volatile VOCs and the no longer use many toxic organic solvents. However, the main component of co-solvent ink is still organic solvent, objectively speaking, co-solvent ink is a classification of solvent-based ink, is an environmentally friendly version of it.

Water-based ink is environmentally friendly, but the weather resistance is poor and needs to be printed on the coated medium, solvent-based ink has good weather resistance, although it does not need to be coated, but it is not environmentally friendly, and the proposal of UV ink is to integrate the environmental protection of water-based ink and the weather resistance of solvent-based ink, and at the same time, there is no need to coat, that is, UV ink is a substitute product for solvent-based ink in the future, and it is also a new direction of development.

Summary. UV ink is a special type of ink, which is a mixture of highly active substances and organic molecules. This ink must be exposed to ultraviolet light after being applied or sprayed to cure.

Often, UV ink is not compatible with water. Because the chemical properties of ink and water molecules are different, after mixing, it will cause damage to pigments, machines, etc., which will affect the printing effect and equipment life. Therefore, contact with water should be avoided when using UV ink, and a special cleaning agent is required to keep the device clean.

Therefore, when using UV ink, contact with water should be avoided, and special cleaning agents should be used to keep the equipment clean and sensitive.

In addition to the special properties of UV ink, it also has many other advantages. First of all, since it can be hardened immediately after curing, the finished product can be used immediately without waiting for drying time. In addition, UV inks are colorful, stable, and non-fading, making them ideal for printing high-quality images and text.

However, there are some issues that need to be paid attention to when using UV ink. For example, during the processing process, attention should be paid to controlling the amount of ink spike residue, adjusting the nozzle height and nozzle angle and other parameters to ensure the printing quality. In addition, since UV ink is a type of organic substance, it is also necessary to pay attention to environmental protection and personal safety when disposing of waste liquid groups.

Waiting. What are the dangers of having a little mineral water in the ink?

UV ink is a chemical substance that contains some specific components to produce its color and printing effect. If mineral water or other liquids are added to UV ink, it may affect the chemical properties and stability of UV ink. Specifically, here are a few of the hazards that can result from the addition of boiling mineral water:

1.Affect the color effect: UV ink and mineral water contain substances that may react and cause the color to light or fade.

2.Coagulation: If too much mineral water is added, it will cause the ink to solidify or lose its original fluidity.

In this way, it will not be able to print properly. Li Beiyou3Damaged printer:

UV inks are designed for specific types of printers. If you add mineral water or other untested liquids to the ink, it may cause some parts to be damaged or malfunction, affecting the entire printing system. In conclusion, since UV ink is specially designed and manufactured for a specific purpose, it is best not to add any other substances (including mineral water) to it.

The differences between the performance of UV system inks and varnishes in cold water and hot water resistance are as follows:1UV system inkUV system ink is a curing printing ink, which needs to be cured by ultraviolet radiation.

Because it uses a curing agent, it has relatively good water resistance, and it is not prone to problems such as discoloration and blurring even when it comes into contact with water. 2.Varnish varnish varnish is a solvent-based or water-based printing ink, the main components are organic solvents and resins, and water-based varnish will also contain some additives.

Compared with UV system inks, varnish has poor performance in water resistance, and is prone to problems such as decolorization and blurring after contact with water. Compared with varnish, UV inks have better water resistance, but their curing process requires the use of ultraviolet radiation equipment, and the production cost is higher. Varnish, on the other hand, is cheaper, but performs relatively poorly in terms of water resistance.

Hello dear. The difference between the performance of UV system ink and varnish on cold water and hot water is: ink:

Under the condition of low temperature sensitive old acacia, UV ink has the phenomenon of particle aggregation, which is easy to react and polymerize. At high temperatures, UV inks also volatilize, making it easy to lose their properties. 2.Varnish:

The cold water resistance of the varnish is very bridge-friendly, and the high temperature resistance also has heat resistance to a certain extent, which can effectively prevent the occurrence of particle aggregation and maintain the stability of product performance. In addition, the varnish also has good adhesion properties, and can achieve a good anti-aging effect after use. Dear, thank you for your support, the above is my reply, I hope to help you, I wish you a happy life
