What are the main printing process? Currently, the popular printing process mainly includes sublimation heat transfer printing, screen printing, bronzing and other three technological processes. The following is a brief introduction of the three printing processes by the heat transfer equipment leader - the supreme printing equipment company:
, sublimation heat transfer - popular term, it is printed, the printed pattern of specialty paper flat cover on the cloth, color paper with cloth slowly into the high temperature and high pressure thermal transfer machines, through the role of high temperature and high pressure, the gasification of the original pattern on the paper quickly, after fumigation to printing chemical fiber cloth surface, wait for after cooling solidification, can produce vivid patterns.
Advantages: this kind of thermal transfer printing method, after printing feel soft and comfortable, bright and full pattern, bright color, good color fastness, environmental protection, in accordance with the export of European and American environmental protection standards. Is a more ideal way to print.
Disadvantages: limited to polyester chemical fiber fabrics, such as cotton and linen, wool, acrylic and other fabrics, currently not suitable.
Screen printing (screen printing) - as the name suggests, is screen printing, because the technology is widely used, in view of the limited space, this paper only briefly introduces the general screen printing process:
(1) first, custom textures better aluminum alloy net frame and grinding, flat on net machine, in the net box surface evenly coated adhesive glue, surface, after dry densities on it evenly spread polyester monofilament net yarn, tension, tension is measured with Newton tensiometer, meets the requirements, after coating glue again, still put cure more than 1 hour.
(2) wash the surface stains of the screen yarn, dry it, apply photographic glue, position and sensitization of the film, develop it by washing, completely hollow out the pattern to be printed, no jagged edges and ghost, apply hardener, and dry it by 50 degrees. At this point, a qualified printing version.
(3) in general, silk screen printing materials used for orders of knitting products are: self-volatilization ink, silica gel ink, thermosetting ink, glue, water pulp, bronzing glue, gold and silver powder, etc.
Three, bronzing - fabric to do bronzing, most of the process similar to screen printing, only in the last bronzing process, you have to use jin Po paper and bronzing machinery. The process flow is roughly as follows: after the clothing surface glue dries, the clothing enters the machine, the pattern faces up, paves the whole, covers the kemper paper, increases the temperature to pressurize, after 10 more than fine, takes out, cools, tears off the waste paper, the quality inspection, repairs, neatly wraps...... A perfect work was born!
[about luggage printing, ribbon printing]
Whether it is luggage or ribbon, the current market printing process, most of the three types of printing process introduced in this paper, the only difference is that the selected printing materials are different.
With the progress and development of science and technology, some new processes, new materials, new methods will continue to enter the field of printing, will bring more benefits to the public.
