scarf box packaging printing (Printing, Graphic Arts, also with the use of Graphic Communications that graphic communications) is the text, drawings, photographs, security and other original manuscripts by the plate making, inking, pressure and other processes, so that the ink transfer to the scarf box packaging paper, woven fabrics It is a technology that reproduces the content of the original in bulk on the surface of materials such as paper, fabric, plastic, leather, etc.
In addition to the selection of appropriate scarf box packaging (paper or other substrates) and ink, the final effect of scarf box packaging still needs to be completed by the appropriate printing method. scarf box packaging printing types are various, different methods, different operations, costs and results also vary. The main classification methods are as follows.
According to the relative position of the scarf box packaging printing plate and non-graphic area, the common scarf box packaging printing methods can be divided into four categories: letterpress printing, gravure printing, lithography and hole printing.
scarf box packaging letterpress printing, scarf box packaging printing plate of the graphic part raised, significantly higher than the blank part, scarf box packaging letterpress printing principle is similar to the seal, the early woodblock printing, movable type printing and later lead printing, etc. belong to the letterpress printing.
scarf box packaging intaglio printing, scarf box packaging plate of the graphic part is lower than the blank part, commonly used in banknotes, stamps and other valuable securities printing.
scarf box packaging lithographic printing, scarf box packaging plate graphic part and the blank part is almost in the same plane, using the principle of oil and water insoluble scarf box packaging printing method.
scarf box packaging hole plate printing, scarf box packaging hole plate printing plate graphic part of the hole, the ink is transferred to the substrate surface through the hole, the common scarf box packaging hole plate printing hole plate printing are hollowed out version and screen version.
According to the method of paper delivery used by the printing machine, scarf box packaging printing can be divided into.
Flat paper scarf box packaging printing: also known as sheet-fed printing. It is the application of flat paper for printing.
Web scarf box packaging printing: Also known as rotary printing. Is the use of web printing method.
According to whether the printing plate is in direct contact with the scarf box packaging, printing can be divided into.
Direct scarf box packaging printing: the printing ink on the printing plate directly in contact with the substrate printing. Such as letterpress printing, intaglio printing, screen printing.
Indirect scarf box packaging printing: the printing plate ink after the blanket transfer printing method on the substrate.
According to whether the use of printing plates, scarf box packaging printing can be divided into.
Edition scarf box packaging printing: printing plates using pre-made printing plates in the scarf box packaging printing method. Such as letterpress printing, intaglio printing, screen printing.
No plate scarf box packaging printing: the printing plate directly through the computer-driven print head (or print head) directly on the scarf box packaging printing method. Such as digital printing.
According to the principle of scarf box packaging printing, that is, according to the printing plate with the printed part and without the printed part in the printing process to produce the principle of printed products, can be divided into physical scarf box packaging printing (Physical Printing) and chemical scarf box packaging printing ( Chemical Printing) two types.
1. physical scarf box packaging printing, ink in the print part is completely an accumulation of bearing, no print part is low concave or convex, and the height of the print part of the different and can not stain the ink, let it blank, so the print part of the ink transfer on the scarf box packaging, only the physical mechanical effect. General letterpress printing, gravure printing, hole printing, dry lithography, etc., are physical scarf box packaging printing (printing surface higher or lower than the non-printing surface).
2. chemical scarf box packaging printing, printing plate without printing pattern part (non-printing surface) is not stained with ink, not by the part of the low concave, convex, or blocked, is due to the chemical effect, so that it produces a water-absorbent ink-repellent film. Of course, the print part (printing surface) ink absorption and water rejection, no print part of water absorption and ink rejection, water and grease dial each other, is still a physical phenomenon, but in the scarf box packaging printing process, must constantly make the non-printing part of the film of water absorption and ink rejection, so the chemical scarf box packaging printing. Offset printing that belongs to this category. Offset printing to add gum substances in the sink solution, so that the source of supply of carboxyl groups of mucus layer, in order to keep the non-printing surface part of the printing plate is not grease infiltration.
