Main features and advantages of screen printing

Screen printing is a kind of printing method which emerged gradually after 1970 and was widely used in the world.Due to its own advantages and a wide range of applications, screen printing has so far had many advantages, and has developed into a printing method that is indispensable to the production of various industries. Some of its advantages are incomparable to other printing methods, and generally have the following advantages:

1 is not subject to the size and shape of the substrate

The big difference between screen printing and general printing is that it can not only be printed on the plane, but also on special shape surface, surface, sphere, concave surface, convex surface. Almost all shapes and things can be printed with screen.Silk screen printing is the preferred way for a variety of three-dimensional printing the irregular shape, such as plastic or metal square rectangle and circle, conical, elliptical, etc., because the silk screen printing on different substrates in the form of different size can adopt different ways of printing, even can go to pure manual printing, depending on the printing workers feel is to guarantee the quality of printing and graphic uniformity, so it when printing there is no requirement for the size of the substrates form, can be printed.This makes screen printing greatly expand the range of printing substrate.

Screen printing can not only be done on small objects, we can see a lot of large advertising posters, curtains and other large outdoor advertising rely on screen printing to achieve.Printing that is commonly used in letterpress, gravure, offset printing – a maximum size of the limit can be printed by mechanical equipment is the size of the whole paper, big can’t print again, and then when screen printing plate making screen frame size can be controlled by itself, but can small, can print can reach the maximum size of 12 square meters even bigger, it proves that screen printing on the printing size at least has more advantages than other printing way.When the size and shape of the substrate is not limited, for the designer’s design: for a wider space, such as printing a large visual impact of the work.Or the combination of printing shapes and patterns on special shapes to convey the design concept, which is better than the simple plane, is equivalent to three-dimensional graphic design.

2 layout soft small printing press is suitable for all kinds of silk screen printing plate soft and full of elasticity, small printing pressure compared with other means, and whether the manual printing or mechanical, can according to actual substrates for printing pressure adjustment, is – “carrot and stick” way of printing, because of the flexibility of screen layout and printing press can be regulatory, compared with other ways of printing it on – some pressure easily broken broken material for printing, such as ceramic and glass.It is no exaggeration to say that screen printing can be printed on almost any substrate except air and water.In soft or hard on a special form of printing has always been serious problems in the printing industry for many years, solved the problems of silk screen printing, because it can be in leather cover cloth printing on the soft material, and can carry on the printing of hard material in special form, it satisfies people of hard and soft printed on different material requirements, since the emergence of silk screen printing, people not only can be printed on the silk fabrics, also can be in – some brittle material, such as glass, ceramics on printing, fully shows the silk screen printing

Be able to withstand less pressure on fragile items printing advantage.

3 thick ink layer, strong three-dimensional sense, strong covering force, rich texture

Silk screen printing is different from other ways of printing and plate making, the plate making, blot out the more sensitive glue, printing ink when the higher the cover thickness, and can be repeated printing substrates to need the thickness of the printing, so the silk screen printing ink thickness from 6 mm to 300 mm, like the thickness of letterpress and offset printing only a few microns no comparable, or even noted gravure printing the administrative levels touch only can reach 15 microns, contrast can be seen, silk screen printing ink covering force relative to the other way is better.The finished product printed by screen printing has a thick layer of brightly colored ink, because it can add the chemical components to keep the color bright for a long time, so the color preservation life is longer, these advantages compared to offset gravure letterpress is that they can not be compared.In screen printing, the ink layer is thick and three-dimensional, so screen printing is the best choice for oil painting with high quality requirements. In addition, screen printing is also responsible for the printing of circuit boards in electronic industry printing.Screen printing can use a variety of printing coatings for printing, to achieve a special touch, foaming ink is one of them, after printing convex and surface texture is obvious, widely used in braille books, easy to touch.With the innovative development of screen printing technology, we can see a lot of silk screen printing on market now copy the way of oil painting, traditional Chinese painting, posters, etc., these high level arts and crafts is the use of screen printing layer printing method, repeating the printing step by step a complete copy of artwork, finally to achieve the effect of the west networks without genuine.This kind of high – level reproduction of art works is also other printing methods can not achieve.

The ink layer of screen printing is thick, and the color of printing has a double sense of touch and vision, which is very different from the other three printing methods. Other printing methods can only achieve planar printing or relatively subtle sense of touch.In general, if you want to do pure white printing on all-black paper, you have to repeat printing on the same part for 3 or 4 times, while screen printing, because of its strong printing coverage, only needs to print once.Look carefully screen printing products, not only strong ink layer effects and tactile feel is good – set of stereo feeling, and silkscreen printing ink layer thickness can be according to the number of printing, or plate making, photosensitive glue daub thickness to determine when the thickness of the silk screen printing can change between from 6 mm to 1000 mm, the visible screen printing ink layer can be adjustable for different designs can be applied to different thickness, different printing effect.

Suitable for all types of inks or coatings

Screen printing ink, in fact, is a variety of types of paint, the use of ink, has been beyond the scope of the definition of ink.Screen printing can be used by the type of paint oil, water, solid powder, paste, paste, adhesive, synthetic resin type and so on, therefore, sometimes the screen printing ink collectively as “printing”.In general it has can use any kind of coating on the characteristics of the printing, the printing paint smooth almost no requirement, as long as you can through the wire net hole fineness of the ink and coating can be used, both toppan gravure plate offset printing limited by plate and machine used for printing ink were required to be higher, grain fine and smooth.Screen printing can be monochrome, multi – color overprint, multi – color block overlay printing, hanging mesh color printing.

5. Strong light resistance

Due to silk screen printing is suitable for all kinds of coating is not affected by coating grain size, even grain is also can use a thick coating, because of the significant characteristics of silk screen, we in order to achieve light fastness or fluorescent effect of the printing effect, can be directly to the coarser particles of light fastness or fluorescent paint in printing coating, allocate to print directly, not need through complex steps, keep printing product permanent gloss is not affected by light and temperature change, can even join the reflective material has enabled glow at night.Silk screen printing ink in the deployment is also very convenient, you can directly add the composition of the paint.Because screen printing process can simply add light resistant coating, screen printing printed matter light resistance, can be widely used in a long time exposed to some of the advertising, such as large outdoor advertising, trademark so that its long-term fadeless and strong retention.

Flexible and varied printing methods

Screen printing, like lithography, intaglio and letterpress, is an industrial-scale, mass-produced printing process designed to produce printed products in large quantities.At the same time, it has the advantages of being easy to learn, convenient, cheap in material price, flexible and diverse in printing mode, quick and labor-saving in printing process, simple and easy to master in technology, etc., which cannot be compared with the other three printing modes, so it has developed particularly fast in recent years.It is not limited by the size of the enterprise, mechanization can be printing production, manual printing can also be mass production.

Of course, quite a lot of screen printing products are achieved by hand printing, which is also the main reason for the rapid development of screen printing, the investment is much smaller than other printing methods.

Screen printing provides designers with a variety of creative design means.Because of its wide range of applications, it is compatible with almost all inks and substrate.Moreover, it has great design potential, and the experimental results of innovative design and application are endless.If a newly discovered or newly invented material is introduced into the field of graphic design, then the first experimental process worth trying is screen printing, which can give designers unexpected fresh results.Screen printing can be done by automated machinery, or on a traditional manual printing pad.It can be mass-produced or printed by hand to produce different effects.
