① The three printing methods of lithography, relief printing and gravure printing can only be printed on the substrate of the plane. Screen printing can be printed not only on flat surface, but also on curved surface, spherical surface and convex surface substrate for printing. On the other hand, screen printing can be printed not only on hard materials, but also on soft materials, which are not limited by the texture of the substrate. In addition, screen printing in addition to direct printing, but also according to the need to use indirect printing method printing, that is, the first screen printing on the gelatin or silica gel plate, and then transfer to the substrate. Therefore, screen printing can be said to be very adaptable, a wide range of applications.
② Thick ink layer, strong three-dimensional sense, rich texture. The thickness of the ink layer of offset and relief printing is generally micron, gravure is about micron, the thickness of the ink layer of flexo printing (aniline) is micron, and the thickness of the ink layer of screen printing is far more than the thickness of the above ink layer, generally up to about micron. Thick screen printing for printed circuit boards with ink layers up to micron in thickness. With foamed ink printing Braille dot Yu, foamed ink layer thickness up to micron. Screen printing has thick ink layer, rich texture and strong three-dimensional sense, which is incomparable to other printing methods. Screen printing can not only monochrome printing, but also color printing and screen printing.
③ Because the screen printing has the characteristics of through printing, so it can use a variety of inks and coatings, not only can use paste, adhesives and various pigments, but also can use pigments with coarse particles. In addition, screen printing ink deployment method is simple, for example, the light pigment can be directly into the ink deployment, which is another major feature of screen printing. Screen printing products have the great advantage of strong light resistance. The practice shows that by using the black ink in coated paper last impression after comparing measured maximum density range, offset printing, embossed, intaglio printing, screen printing and one of the biggest range of density value, so the light fastness of silk screen printing products than other kinds of printing products of light fastness is strong, more suitable for the outdoor advertising, signs.
④ At present, the printing area of general offset printing, letterpress printing and other printing methods is the largest size of the full sheet, more than the full sheet size, is subject to the limitations of mechanical equipment.And screen printing can be large area printing, screen printing products today up to 3.65 meters, or even larger.
The above four points are the differences between screen printing and other printing, as well as the characteristics and advantages of screen printing. Understanding the characteristics of screen printing, in the selection of printing methods, you can develop strengths and circumvent weaknesses, highlight the advantages of screen printing, in order to achieve a more ideal printing effect.
