In addition to selecting the appropriate substrate (paper or other printing material) and ink, the final effect of the print or need to be done by appropriate printing. There are various types of printing, different methods, the operation is different, the cost and effect are also different. The main classification is as follows:
The printing method is classified according to the relative position of the graphic and non-graphic area on the printing plate
In accordance with the relative position of the graphic and non-graphic areas on the plate, the common printing methods can be divided into letterpress printing, gravure printing, lithography and stencil printing.
(1) letterpress printing, printing plate part of the convex, significantly higher than the blank part of the printing principle is similar to the seal, the early woodplate printing, movable type printing and later printing of the word and so on are letterpress printing.
(2) gravure printing, printing plate part of the graphic below the blank part, commonly used in banknotes, stamps and other securities printing.
(3) lithographic printing, plate graphic part and the blank part is almost in the same plane, the use of oil and water immiscible principle of printing the way.
(4) stencil printing, printing part of the plate for the hole, the ink through the hole transferred to the substrate surface, the common hole printed with hollow version and screen version.
The printing method is classified according to the feeding method of the printing press
According to the printing method used by the printing press, printing can be divided into:
Flat paper printing: also known as sheetfed printing. Is the application of flat paper for printing.
Web printing: also known as rotary printing. Is the use of web printing method.
The printing method is classified according to whether the printing plate is in contact with the substrate
According to the printing plate is directly in contact with the substrate, printing can be divided into:
Direct printing: printing plate on the ink directly with the substrate contact printing. Such as letterpress printing, gravure printing, screen printing.
Indirect printing: printing of the printing ink through the blanket on the substrate printing method.
According to the printing plate is used to sort the printing method
According to whether the use of printing, printing can be divided into:
Printed version of the plate used in pre-printed version of the printing plate in the way. Such as letterpress printing, gravure printing, screen printing.
No printing: A method of printing directly on a substrate by a computer-driven printhead (or print head). Such as digital printing.
The printing method is classified according to the printing principle
According to the principle of printing, that is, according to the printed version of the printed part and no print part of the printed process in the printing of the principle, can be divided into physical printing (Physical Printing) and chemical printing (Chemical Printing) two categories.
1. Physical printing, ink in the printed part of the pile is a complete load, no printed part of the concave or convex, and the print part of the height of different and can not stained with ink, let the blank, so the mark Part of the ink transferred to the printed matter, only a physical mechanical role. General letterpress printing, gravure printing, stencil printing, dry lithography, etc., are physical printing (printing surface above or below the non-printed surface).
2. Chemical printing, printing plate without printed parts (non-printed surface) is not stained with ink, not by the part of the concave, raised, or blocked, but because of chemical action, to produce water absorption Of the film. Of course, the printed part of the (printing surface) ink and water repellent, no part of the water absorption ink, water and grease against each other, is still a physical phenomenon, but in the printing process, Ink of the film, it is a chemical printing. Offset is like this. Offset in the tank solution to add glue substances, so that the source of the supply of carboxyl groups of the mucous layer, in order to maintain the printing plate part of the non-printing surface is not fat.
