What kinds of printing the current main method? - Printing, screen printing, rotary screen printing - screen printing industry, especially web

Textile Printing There are several ways in which considerable commercial importance, there are two printing methods: screen printing and roller printing. The third way is to heat Transfer printing , The relatively low importance. Other rarely used in the textile production of the printing method: wooden template printing, wax valine (ie, wax) printing, tie-dyed yarn, cloth printing and resist printing. Many textile printing factory using screen printing method and printed fabric roller printing method. Most printing plant thermal transfer printing is also produced in this way.

1, screen printing Screen printing, including printing screen preparation, printing screen (for screen printing process had been made with a thin silk, the process is called screen printing. Although no longer used silk screen , but the printing process screen printing is still frequently used name.) by the tension in the wood or metal frame with fine mesh nylon, polyester fiber or metal wire fabric. Mesh fabric coated with a layer of opaque to non-porous film. A pattern Office, to remove the opaque film, leaving a fine mesh screen, this region is part of the pattern to be printed. Most commercial mesh fabric is coated with a layer of photosensitive films first, and then remove the pattern through the light-sensitive parts of the film method and show patterns. Printed fabrics in place to screen for printing. Pour the printing paste printing frame, by Scraper (A kind of similar to windshield wiper such tools) to force them from office through the mesh screen.

Prints in each color requires a screen alone, the purpose of different colors were produced. Example 3 needs 3 Color Printing Network box The 3 colors are printed on the fabric up. In addition, the pattern in every color of the pattern to be so precise positioning in the sieve after the printing pattern position accuracy, to avoid such as a rose is printed on a green stem red petals in the middle of this phenomenon. Printed on the flower is the color accuracy of all printed pattern to the fabric industry terminology.

There are three ways to achieve screen printing, application of each method is basically the same principle. The first is a hand-screen printing, very common in the 1920s, has been widely employed. Until the mid-1950s, modern technology to give this process before automation tools, hand screen printing screen printing has been the only way. The second method is called automatic screen printing (also known as flat-screen printing and automatic flat screen printing). In the mid-1960s, with further development, and automatic mesh shape from hand turned rotary screen flat screen shape development. The third method is called the round screen printing or rotary screen printing, is currently the most widely used screen printing method.

Second hand screen printing Hand-screen printing station in a long board for commercial production (sets board for 60 yards). Smooth ground floor cloth printing paper board in Taiwan, the Taiwan plate pre-coated surface of a small amount of viscous material. And printing workers continuously along the entire platen hand mobile network box, and each print a screen frame, until all the printed fabric finished. Each network box corresponds to a printing color. This method of production rate per hour 50-90 yards. Manual screen printing business are also a lot of good clothes for cutting printed piece. Film printing processes in the clothing, garment printing process and arrange with the process. Clothing pieces together before sewing, or put a unique custom design printed clothing chip. Because the manual screen printing can make for large flower pattern back to a large network box, so by the printing method can also be printed, such as beach towels, new printing apron, curtain and shower curtain fabrics.

Manual screen printing is also used for limited production, highly fashionable women clothes and the production of small quantities of products for the Pathfinder market.

3, automatic screen printing Automatic screen printing (or flat screen printing) in addition to process is automated, the other hand the same screen, so faster. Printed fabrics by wide rubber conveyor belt to screen office, not (the same as manual screen printing) in a long table. As with the manual screen printing, automatic screen printing is intermittent rather than continuous process. In this process, the fabric screen to move the following, and then stop, screen scraper for scraping web printing (automatically scrape a), scraping and India after the fabric continue to move to the next screen frame below, the production rate of about 500 yards per hour . Automatic screen printing fabric Tuo only for the entire volume, cutting the garment is generally not such a good method of printing. As a commercial production process, as favored production of more efficient rotary screen printing, therefore, automatic screen printing (ie flat screen printing) production is declining.

4, rotary screen printing Several important aspects of rotary screen printing screen printing method is different from the other. In the next section, rotary screen printing and roller printing will be described as a continuous process line, printed fabric is transported through the wide rubber band to the continuous motion, rotary spendthrift below. Screen printing, the rotary screen printing production and the fastest, more than 3500 yards per hour. Use seamless perforated metal mesh or plastic mesh. The largest circumference greater than the 40-inch rotary screen, so the maximum size is also larger than the flower back to the 40-inch. More than 20 chromatography of the rotary screen Printing machine Has also been produced, this printing method is slowly replaced by roller printing.

5, roller printing Like newspaper printing roller printing is a more than 6000 yards per hour can produce printed fabrics, high-speed technology, this method also called mechanical printing roller printing, the pattern by engraving copper rollers (or rolls) printed on the fabric on. Copper cylinder can be carved out of very fine closely arranged fine lines, which can print a very detailed and soft patterns. For example, fine, dense Peilizili vortex pattern tweed printing roller printing is produced by a class of patterns. Spendthrift carving patterns the designer should be exactly the same artwork, each roller suit their needs in a simple carving. (Specific printing process in the textile industry, five roll printing, roller printing and other six sets of commonly used to represent the six chromatic colors or roller printing.

Roller printing is to use the minimum-volume printing production methods, output continued to decline every year. If the production volume of each pattern of not very large, this method is not economic. In most cases, preparation and equipment roller adjustment costs are high, consumption of long, making use of this method is not printing the economy. However, the roller printing are often used to have a very fine line printing patterns, such as Paisley vortex pattern tweed print and large print many seasons are the main prints.

Sculpture spendthrift depends on printing machine and prints. Most of the printing machine can be configured to the maximum circumference of 16 inches of spendthrift, that is India
