What is the form of printing?

Today, I will introduce you to several printing methods of polyester bolting cloth.

First, rotary screen printing:

There are several important aspects of rotary screen printing that differ from other screen printing methods. The rotary screen printing, like the roller printing described in the next section, is a continuous process in which the printed fabric is conveyed through a wide rubber band underneath the moving circular cylinder. In screen printing, the production of rotary screen printing is the fastest, more than 3,500 yards per hour. Use a seamless perforated metal mesh or plastic mesh. The largest cylinder circumference is greater than 40 inches, so the maximum flower return size is also greater than 40 inches. More than 20 sets of color rotary screen printing machines have also been produced, and this printing method is slowly replacing the roller printing.

Second, the roller printing:

Roller printing is like a newspaper printing. It is a high-speed process that can produce more than 6,000 yards of printed fabric per hour. This method is also called mechanical printing. In roller printing, the pattern is printed on the fabric by engraving a copper roller (or roller). The copper drum can be engraved with very fine lines that are closely arranged, so that a very fine and soft pattern can be printed. For example, the fine, dense Pelisley vortex tweed print is a type of pattern printed by roller printing. The flower carve engraving should be exactly the same as the design of the graphic designer. Each flower color requires an engraving roller. (In the textile industry specific printing process, five-roll printing, six-roll printing, etc. are commonly used to represent five sets of color or six sets of color roller printing. Roller printing is the use of the least large-scale printing production method, the output continues to decline every year. If each production The batch size of the pattern is not very large, and this method is not economical. In most cases, the cost of drum preparation and equipment adjustment is high and the length is long, making printing using this method less economical. However, the drum printing is often used to have The prints of extremely thin lines such as the Paisley vortex tweed print and the main prints printed in large numbers in many seasons.

The size of the engraving cylinder depends on the printing machine and the print. Most printers can be equipped with a maximum circumference of 16 inches, which means that the print pattern can not exceed 16 inches. The width of the flower tube should be slightly larger than the width of the printed fabric so that the fabric can be completely printed with the edge of the fabric. Once ready, the printing cylinder can be used almost unrestricted, and there are no problems in printing millions of yards of fabric.
