Print Classification
Office: Refers to stationery, envelopes, office forms and other printed materials related to the office.
Propaganda: Refers to a series of printed materials related to corporate publicity or product publicity such as posters, promotional leaflets, product manuals, etc.
Production: refers to large quantities of printed products directly related to production products such as packaging boxes and stickers.
Printing plate classification
1. PS version: suitable for color or monochrome precision printing, the applicable machine is a lithographic printing machine. Generally, the reserved version can be used for reprinting. The printing quality is very precise and almost perfect.
2. Resin version: such as business card machine and disc machine are suitable for a small amount of business cards, shop cards, invitations and stickers.
3. Zinc plate: suitable for business card machine, disc machine, bronzing machine, especially used for bronzing, embossing (use version), good quality, and this plate material for lithographic printing Plate).
4. Paper version: suitable for fast printing machines, etc. This version cannot be stored because it is a paper version, and its cost is relatively low.
5. Screen version: It is suitable for screen printing machines, etc. This version is suitable for printing some special materials, such as PVC and clothes.
6. Aluminum version: It is suitable for lithographic printing machines, but because of the low printing resistance and the high proportion of poor retention, there are few users.
Classification of printing
Traditional classification: according to the layout structure of the printing plate
1: Letterpress printing
Any printing method where the printed text is higher than the blank, and the ink is coated around the graphic, and the graphic imprint is copied to the surface of the printed matter through the action of pressure is called relief printing.
2: Lithography (offset printing)
Nowadays, offset printing is usually called lithography. The graphics and blank of the printing plate are on the same plane. The principle of oil-water separation allows the graphics to finally be transferred to the surface of the printed matter.
3: gravure printing
Intaglio printing and letterpress printing are just the opposite. The graphic part is concave, while the blank part remains the original plane. The graphic part receives the ink layer, and the pressure of the printing cylinder transfers the ink layer to the surface of the printed matter to replicate the printed matter.
4: Filter printing
Screen printing is typical of filter printing. The ink penetrates through the mesh (graphics) of the fabric and is copied into graphics on the surface of the substrate.
The above four methods are called four printing methods.
According to the development of modern printing, it can also be divided into the following types:
5: Flexographic printing (relief printing)
At the beginning, the flexographic printing plate was named flexographic printing because of the use of volatile liquid color ink made of aniline dyes, and the plate material used rubber plates. However, with the development of science and technology, plate materials and inks have changed a lot, and flexographic printing has become today's flexographic printing.
6: Special printing
According to different printing materials and processes, special printing can be divided into: gold and silver printing; anodized aluminum hot stamping; concave and convex embossing; die cutting indentation; metal printing; Bubble printing; inkjet printing; holographic printing, etc.
In terms of technology, all printing can be classified into four major printings;
In terms of actual materials and characteristics, of course, printing also includes flexographic printing and special printing.
Printing machine classification
1. Lithography: such as multi-color machine, four-color machine, two-color machine, single-color machine, rapid printing machine, etc.
2. Letterpress printing: such as business card machine (resin version), type printing, zinc letterpress, set number, etc.
3. Gravure printing: such as the printing of glass bags for instant noodles and the packaging of aluminum foil bags for biscuits.
4. Hole printing: such as screen printing, circuit board printing, cloth flower printing, canning printing, inscription printing, local polishing, etc.
