Seven characteristics of screen printing compared with other printing methods

There are many characteristics of screen printing, the most fundamental point is that the printing adaptability is strong, so it is called that except air and water can not be printed, it can be printed on all substrates with different materials and different surface shapes, and it is not affected by Limitation of printing area. Compared with other printing methods, screen printing has the following characteristics.

(1) Low cost and quick results.

Screen printing can be either mechanized production or manual operation, its investment can be large or small, from thousands of yuan to individual manual production, to tens of millions of yuan to build a modern screen printing factory. Because this printing method requires lower equipment and material costs than other printing methods, and its plate making method and printing method are also relatively simple, it is currently particularly interesting to Shikaoka personnel to create a good opportunity for them to re-employment. Those simple printing that cannot be completed by flat printing, embossing and gravure printing can be completed by silk screen printing. Shanghai printing screen printing can be divided into industrial screen printing and art screen printing. Fine art screen printing can be used to print exquisite prints and copy precious oil paintings. Its products have bright colors and thick ink layers. The strong sense of the picture is unmatched by other printing methods.

(2) Adapt to the printing of irregular substrate surface.

The silk screen is very flexible. In addition to printing on flat objects, it can also be printed on the surface of curved, spherical or uneven shaped objects, such as various glassware, plastic, bottles, lacquerware, wood, etc. It can be printed if it cannot be printed by offset printing, embossing or gravure printing.

(3) Strong adhesion and good ink sticking.

Due to the characteristics of the silk screen version, the ink penetrates the silk screen hole and directly adheres to the surface of the substrate. According to the requirements of the substrate material, it can be printed with ink, or with various paints, pastes, glues, etc. Other printing methods are limited due to the fine requirements of the pigment particle size in the ink.

(4) The ink layer is thick and solid.

Among the four printing methods, the ink layer of screen printing is thicker, rich in texture and strong in three-dimensional. The offset printing ink layer is 1.6 microns, the relief printing is about 5 microns, the gravure printing ink layer is about 12.8 microns, the flexographic printing ink layer thickness is 10 microns, and the screen printing ink layer thickness can reach 60 microns. Thick film screen printing ink layer thickness can reach about 1 mm. Screen printing is used to print Braille, and the thickness of the ink layer can reach 300 microns. The method is to directly make a positive picture on the screen version according to the original through a braille machine, and after printing on the screen printing foaming ink, heat and dry immediately, and then the braille can be formed.

(5) Strong light resistance and good color formation.

If you compare the range of maximum density measured with black ink on copperplate paper after one embossing, offset printing is 1.4 relief printing is 1.6 gravure printing is 1.8, and the maximum density value range of screen printing can reach 2.0. Screen prints are extremely lightfast and have better color formation than offset printing. In offset printing, if you want to use the proofing mechanism to take the opaque printing surface covered by white, you need to reverse the paint in the same part 3-4 times, and the screen printing only needs to be printed once. In terms of the color formation of printed products, the texture and color of screen printing far exceed that of offset printing, even for the same color printed product with fairly light colors.

The thickness of the screen printed ink layer can be thicker or thinner. For example, in four-color screen printing with screen printing, Shanghai Printing requires that each color ink layer is not thick, but a thin ink layer. The method of thinning the ink layer is to change the printing speed, ink viscosity, screen thickness, squeegee shape, printing pressure and inking angle and other variable factors to make the screen printing ink layer thinner, or even thinner.

(6) Extensive printing materials.

It can be paper, cardboard, wood, metal, textiles, plastic, cork, leather, fur, ceramics, glass, decals, transfer paper, and a combination of various materials, so screen printing is not only in the printing industry. In addition to the application of everything, it is also widely distributed in the printing and dyeing, clothing, signage, radio, electronics, ceramics and packaging and decoration industries.

(7) Large printing area.

Lithography 'relief printing, gravure printing and flexographic printing are now restricted by the size of the printing format, while screen printing can be used for large format printing. In particular, with the rapid development of the advertising market, the large-scale outdoor printing of screen-printed outdoor advertising has become an increasingly important part of the advertising market. The largest screen-printed outdoor advertisements can now reach 2.2 × 3.8 meters and 2.2 × 4 meters.

Temperature and humidity data loggers are among the most popular, and a range of product solutions exist to adapt to any application. Environmental temperature and humidity data loggers generally feature built-in sensors and are used to measure ambient temperature and humidity in many settings. Popular applications include calibration rooms, greenhouses, warehouses, basements, attics, and even cigar humidors.
