Classification of printing, printing plates, printing presses and prints

Print classification

Offices: Refers to office-related prints such as letter paper, envelopes, and office forms.

Publicity: Refers to posters, leaflets, product brochures, and other printed materials related to corporate publicity or product promotion.

Production category: refers to large quantities of printed matter directly related to the production of products, such as packaging boxes and adhesive labels.

Printing plate classification

1. PS version: suitable for color or monochrome printing, and the machine is lithographic. Normally reserved for use in reprinting, the quality of printing is very precise and almost perfect.

2. Resin version: If the name card machine, disc machine for a small amount of general business cards, shop cards, invitations, stickers can be.

3. Zinc plate: Suitable for business card machine, disc machine, hot stamping machine, especially used in bronzing, embossing (used version), good quality, and lithographic printing with this plate (the first domestic lithographic printing Plate).

4. Paper version: Suitable for fast printing machines, etc. Since this version is a paper version, it cannot be stored and its cost is relatively low.

5. Screen: Suitable for screen printers, etc. This version is suitable for printing some of the more special materials, such as PVC, clothes and so on.

6. Aluminium version: suitable for lithographic printing presses, but due to the low print-resistance and the high proportion of defective prints, there are few users.

Printing classification

Traditional classification: According to the layout of the printing plate

1: Letterpress printing

The printing method where the printed graphic is higher than the blank and the ink is coated around the graphic, and the graphic print is copied to the surface of the print by the action of pressure, is called relief printing.

2: Lithography (offset printing)

Nowadays, it is customary to refer to offset printing as lithographic printing. The graphic and blank parts of the printing plate are on the same plane. The principle of oil-water separation allows the final transfer of the graphic to the printed surface.

3: gravure printing

Gravure printing is just the opposite of letterpress printing. The graphic part is concave, while the blank part remains in its original plane. The graphic part accepts the ink layer, and the ink layer is transferred to the surface of the printed matter by the pressure of the printing cylinder to reproduce the printed matter.

4: Filter printing

Screen printing is typical of filtration printing. The ink seeps through the fabric's mesh (text) and is reproduced on the surface of the substrate.

The above four methods are called four printing methods.

According to the development of modern printing, it can be divided into the following categories:

5: Flexographic printing (a relief printing)

At the beginning, the flexographic plate was named aniline for the use of volatile liquid color inks made from aniline dyes, and the plate was made of a rubber plate. However, with the development of science and technology, plates and inks have undergone great changes, and aniline printing has also 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; electro-aluminum hot stamping; embossing and embossing; die-cutting and indentation; metal printing; sticker printing; coating and printing; three-dimensional printing; Bubble printing; inkjet printing; holographic printing and so on.

From the process point of view, all printing can be classified into four major printing;

From the actual materials and characteristics, printing of course also includes flexographic printing and special printing.

Printing press classification

1. Lithography: such as multi-color machine, four-color machine, two-color machine, monochrome machine, fast printing machine and so on.

2. Letterpress printing: such as business card machine (resin version), type printing, zinc letterpress, set number, etc.

3. Gravure printing: such as instant noodles, glass bag printing, biscuits, aluminum foil bag packaging.

4. Stencil printing: such as screen printing, circuit board printing, cloth printing, canned printing, nameplate printing, local glazing, etc.
