Screen printing ink is a kind of printing ink, which has a wide variety and a variety of classification methods. However, there are several main classification methods.

According to the characteristics of inks, they can be divided into fluorescent inks, bright inks, fast-fixing inks, magnetic inks, conductive inks, fragrance inks, ultraviolet drying inks, sublimation inks, transfer inks, etc.

Classification according to the state presented by the ink; Colloidal inks, such as water-based inks, oil-based inks, resin inks, starch pastes, etc. Solid inks, such as toner for electrostatic screen printing.

Classification according to the substrate:

Paper inks: oil-based inks, water-based inks, high-gloss inks, semi-glossy inks, volatile drying inks, naturally drying inks, coating paper inks, plastic synthetic paper inks, cardboard carton inks.

Ink for fabrics: water-based inks, oil-based inks, emulsion-based inks, etc.

Inks for wood: water-based inks, oil-based inks.

Metal inks: special inks for different metals such as aluminum, iron, copper, stainless steel, etc. Leather inks: special inks for printing leather.

Inks for glass ceramics: inks for glass instruments, glass crafts, and ceramic utensils.

Inks for plastics: inks for polyvinyl chloride, inks for styrene, inks for polyethylene, inks for propylene, etc.

Inks for printed circuit boards: conductive inks, corrosion-resistant inks, electroplating-resistant and fluorine-resistant and alkali-resistant inks.

The characteristics of screen printing can be summarized in the following aspects:

There are many types of inks that can be used for screen printing. That is: oil-based, water-based, synthetic resin emulsion type, powder and other types of inks.

The layout is soft. The screen printing layout is soft and has a certain elasticity, which is not only suitable for printing on soft items such as paper and cloth, but also suitable for printing on hard items, such as glass, ceramics, etc.

Screen printing has a low imprint power. Due to the low pressure used in printing, it is also suitable for printing on fragile shopping bodies.

The ink layer is thick and has strong coverage.

It is not limited by the shape of the surface of the substrate and the size of the area. From the foregoing, it can be seen that screen printing can not only be printed on a flat surface, but also printed on a curved or spherical surface; It is not only suitable for printing on small objects, but also for printing on larger objects. This printing method has a lot of flexibility and a wide range of applicability.

1. What is silk screen printing ink?

5. For fabrics.

What is screen printing ink and an overview of the uses of screen printing ink.

Silk screen printing ink generally refers to mesh ink, screen screen printing ink refers to the ink of various substrates printed through various mesh plates, screen printing ink is widely used, all kinds of household appliances panels, film buttons, high-grade nameplates, adhesive stickers, all kinds of decal printing, electronic product printing, at the same time, according to the different substrate materials, choose different inks, such as untreated or treated PET materials, transparent PET, scratch-proof PET, etc., self-adhesive paper, these types of inks are somewhat different.

3.The viscosity of screen printing ink and gravure printing ink is different, gravure ink is thinner, and screen printing ink is much thicker! Hello!

A look at the pp forum, a lot of gravure information, there are a lot of friends who do gravure printing If it is helpful to you, hope.

Abstract Hello. The screen printing ink thinner has the diluent isophorone, which is relatively good in dilution. Tiannashui 783 These are all blended, and these are not. Isophorone works well.

Silk screen ink thinner, which thinner is there.

Hello! The screen printing ink thinner has the diluent isophorone, which is relatively good in dilution. Tiannashui 783 These are all blended, and these are not. Isophorone works well.

These diluents are mainly divided into fast-drying solvents, slow-drying solvents, and medium-dry solvents.

Screen printing is mainly divided into solvent inks (oil-based) and water-dispersed inks, screen inks generally require a small amount of viscosity, and the ink is not easy to extract yarn. The components of inks are pigments, resins, fillers, additives.

Silk screen printing ink is a kind of ink specially used for screen printing, and its formula ratio is crucial for the quality and use effect of the ink. The following will introduce several commonly used screen printing ink formula ratios and their advantages and disadvantages.

Proportion of ordinary screen printing ink formulation.

This is a common screen printing ink formula ratio, the formula is: pigment 30%, resin 10%, solvent oil 60%. The advantage of this ink is that it is cheap and has a wide range of applications, but there are also some shortcomings, such as its printing effect in general, not bright enough.

Formulation ratio of high-performance screen printing inks.

The proportion of pigment in the formula ratio of this silk screen printing ink is high, usually using the ratio of 50% pigment, 20% resin, and 30% solvent oil. The printing effect of this ink is better, the color is bright, and the pattern is clear. However, there are also some disadvantages, such as high **, which is not suitable for mass production and popular product use.

Proportion of environmentally friendly screen printing ink formulation.

With the gradual improvement of environmental awareness, environmentally friendly screen printing ink has become an emerging type of ink. The formula ratio is usually 30% pigment, 25% resin, 25% solvent oil, and 20% reducer. The advantages of environmentally friendly screen printing ink are environmental protection and safety, and it is also suitable for mass production.

However, due to the addition of reducer, it will lead to a slight reduction in its printing effect.

Ratio of metal screen printing ink formulation.

Metal screen printing inks usually use pigments containing metal powders, so some special additives need to be added to their formulations. The formula ratio is usually 30% metal powder, 25% chaotic resin, 25% solvent oil, and 30% special additives need to be added. The printing effect of this ink has a high gloss, which can imitate the effects of metal drawing, copper wire, etc., but it is higher and requires more stringent printing conditions and technology.

Proportion of fluorescent screen printing ink formulation.

Fluorescent screen printing ink is often used in advertising, safety warnings and other fields, and its formula is usually 40% pigment, 15% resin, and 45% solvent oil. It is characterized by bright colors and high contrast, which is easy to attract people's attention, but it is necessary to pay attention to the light situation and the impact on the human body when using it.

In general, different screen printing oil Kaisheng ink formula ratios are suitable for different printing needs and industries, and need to be selected according to the specific situation. At the same time, it is also necessary to pay attention to the storage and use conditions of the ink to ensure its quality and effect.

Summary. 1. Directly use cheap water-based diazo photosensitive adhesive to dry the screen, first coat the hardened water and then coat the solid film solution, from now on, any screen does not need to use expensive oil-based or water-oil dual-purpose photosensitive adhesive, nor do you use other screen protection agents to directly print a variety of water-based or oil-based slurries and high acid and alkali slurry.

2. The use and characteristics of solid film solution A and B.

Sex; The normal ratio of solid film liquid A and B is 1: 1, A is easy to wash and anti-sticky after plugging, and the adhesive paper does not stick to the countertop, B is wear-resistant and corrosion-resistant.

Third, even if it is 120 lines x 350 mesh fine.

As long as the pattern is on the O-protection firming solution, there is no need to worry about wiping the screen and delaying the work.

Fourth, the amount of solid film liquid is particularly provincial, the coating area of 1 square meter does not exceed yuan, and the 5 cm cotton cloth is soaked in the upper and lower sides of the screen and wiped once, and then the cold wind blows away the film-like solid film liquid in the flower position, and then the whole screen can be used immediately after drying or drying the whole screen, and the screen within 150 meshes. It is not easy to form a film between the meshes, which can avoid blowing wind and will not block the flower position. Therefore, it is more cost-effective, time-saving and easy to use than various traditional protective materials.
