Traditional screen printing is screen printing cloth, synthetic fabrics or metal screen taut on the screen frame, the use of hand engraved lacquer film or photochemical plate making methods to produce screen printing plates. Modern screen printing technology has improved, the use of photographic materials to take photographic plate making method of screen printing plate, in the printing, through the squeegee extrusion of the ink through the graphics part of the mesh transfer to the substrate, the formation of the same graphics as the original. In order to adapt to the increasingly fierce market competition, to meet more and higher customer requirements, screen printing technology has been rapidly improved and enhanced in recent decades, compared with other printing methods mainly presents the following five characteristics.

1.Applicable to various types of inks
Screen printing can use a wide range of inks, including pastes, pastes, paints, adhesives, and solid powders, beyond the usual definition of ink. Therefore, screen printing inks are sometimes referred to as “printing materials”. In addition, compared to other printing methods, screen printing is not very demanding on the fineness of the pigment particles in the ink, as long as the ink and coating can pass through the screen mesh fineness can be used.

2.Good outdoor performance
Since screen printing has a wide range of inks, it is possible to use inks with light-resistant pigments or fluorescent pigments, so that the printed image is not affected by the temperature and sunlight and maintains its luster, and can even glow at night. This feature determines that screen printed products can be used outdoors for advertising and signage.

3.Not subject to enterprise restrictions
Screen printing, like lithography, letterpress and gravure printing, can be produced on an industrial scale. At the same time, it also has the other three printing methods incomparable ease of plate making, cheap, flexible and diverse printing methods, easy to grasp the technical characteristics, so it can not be restricted by the size of the enterprise, even if the individual operation is also feasible.

4.Wide range of printing
Screen printing has great flexibility and wide applicability. With screen printing, printing can be done on flat surfaces, on substrates with special shapes, and even on concave and convex surfaces. In addition, screen printing has a wide printing area, which can be printed on large areas, up to 3m x 4m or more, and on ultra-small, ultra-precise items. Because the screen printing plate is soft and flexible, the printing pressure is low, so if you need to print on soft substrates such as textiles, as well as a variety of glass and ceramic vessels that are easily damaged by pressure, you can choose screen printing.

5.Wide range of adjustable ink layers
Screen printing is actually quite a wide range of applications, as many people jokingly say, in addition to air and water can not be printed, it can be printed on a variety of materials and surface shapes of different substrates. Its substrates include paper, plastic, wood products, metal products, glass, ceramics, signs, textiles, leather products, CDs, magnetic cards, etc.. What has attracted attention in recent years is perhaps its application in the high-tech electronics industry.

What are the types of materials for screen printing mesh?

1 nylon polyester screen warp weft uniformity is very poor, the mesh size is inconsistent, the shape varies, the surface finish is also very poor, the tensile strength is very low, the quality of the production of the screen plate is not ideal, the resolution of the image is poor, the printing resistance is also unsatisfactory, so it has been rarely used! The disadvantage is that the elongation is too large, easy to age and deteriorate, the light resistance is not good, and it is easy to become brittle when exposed to light for a long time!

2. Nylon wire mesh is made of chemical synthetic fibers, belonging to the polyurethane system. Nylon wire mesh has strong abrasion resistance, chemical resistance, water resistance, and elasticity, and because of the uniformity of the silk warp and smooth surface, the ink passability is also good! Its shortcomings are, nylon mesh stretching, this screen in a period of time after the taut screen, the tension has been reduced, so that the screen printing screen slack, precision decline, so not suitable for printing size precision requirements of the industry!

3. stainless steel wire mesh made of stainless steel materials, stainless steel wire mesh is characterized by good wear resistance, high strength, small stretching, due to the fine wire diameter, the ink through the performance of good mechanical properties of stainless steel wire mesh, chemical properties, stable dimensional accuracy, its shortcomings are, poor elasticity, more expensive, screen stretching can not be restored to its original state! Stainless steel wire mesh is suitable for circuit boards and integrated circuits and other high-precision printing!

4. Monofilament polyester screen yarn, suitable for general screen printing factory, garment printing factory, handbag screen printing, organic glass, plastic panels and other screen printing polyester screen, also made of chemical synthetic fibers, belongs to the polyester screen, with the advantages of high temperature, water resistance, chemical resistance, polyester screen in the external pressure, its physical properties are stable, small stretch, its shortcomings are and nylon screen The disadvantage is that it is less wear-resistant than nylon wire mesh. In addition to the advantages of nylon screen printing, polyester screen is also suitable for printing in industries that require high dimensional accuracy, such as printed circuit boards!

How to choose high quality screen printing mesh

/0 Comments/in /by

Screen printing mesh is an indispensable material in the screen printing process. The quality of screen printing mesh is related to the screen and production efficiency. Buyer also hope to choose the screen printing mesh that best meets their own requirements, but during the process of selection, many customers have misunderstandings about these aspects, and do not know which screen print mesh products and brands are better. Today, Jusda will explain to you further about what kind of screen printing mesh is better.

Everyone’s choice of screen printing mesh products and brands should be compared correctly. We should have a certain comparison of different brands, pay attention to the quality of them, and also understand our own needs. In the process of comparison, if you correctly consider various situations and have a better understanding of your actual needs, then the entire selection will be in the right way.

Generally, the pigment particles of the ink are relatively fine, and the ink has good passability. This ink can also pass well when using a high-mesh screen; while the ink with high pigment concentration has fine particles, but its permeability will be relatively low.

Absorptive substrates with rough surfaces require more ink to achieve the best coverage of the ink layer, so a thicker screen is used; non-absorbent substrates with smooth surfaces require relatively less ink, so a higher mesh screen print mesh should be used.

There are many different screen printing mesh brands and manufacturers on the market. If you need to purchase in large quantities, you must carefully understand various screen printing mesh products and brands. This is the premise of making a good choice. Different people will have certain differences in their needs. If you can make a choice based on your actual needs, it will be more suitable. If the choice you make does not take into account your own needs at all, then will be greatly affected.

Based on the above, screen printing mesh manufacturers will definitely develop towards a more diversified perspective in the future development process, and at the same time, they should better conform to some methods of the development of the times. After understanding all aspects correctly and knowing more aspects, then the future will be guaranteed.

Jusda exerts its comprehensive competitiveness and develops an excellent screen printing screen that is accurate in every production process, from yarn to mesh, and provides reliable and affordable screen printing mesh product and accessories for various screen printing manufacturers.
