Mechanical types

Printing machines are divided into letterpress, lithographic, gravure and stencil printing machines according to the printing plate form; the mounting plate and imprinting structure are divided into flat and round flattening types. and rotary presses.

By type of printing plate

1. Letterpress printing machine: a machine that uses letterpress plates to complete the printing process. Such as business card machine (resin version), type printing, zinc letterpress, set number, etc.

2. Lithographic printing machine: A machine that uses a lithographic plate to complete the printing process. Such as multi-color machines, four-color machines, two-color machines, single-color machines, high-speed printing machines, etc.

3. Gravure printing machine: A machine that uses gravure to complete the printing process. Such as glass bag printing of instant noodles, aluminum foil bag packaging of biscuits, etc.

4. Screen printing machine: A machine that uses a screen plate to complete the printing process. Hole printing: such as screen printing, circuit board printing, cloth printing, can printing, nameplate printing, partial glazing, etc.

Classification according to the form of paper used

1. Sheet-fed printing press: a printing press that uses sheet-fed paper.

2. Web printing press: a printing press that uses web paper.

Classification by imprinting structure

1. Flat-flat printing press: a printing press in which both the plate support and the imprinting body are flat`

2 1. Circular flat printing press (platform printing press): A printing press in which the printing plate support body is flat and the impression body is cylindrical.

3. Stop-rotary printing press: The printing plate cooperates with reciprocating motion. When moving forward, the impression cylinder rotates once, and when returning, the impression cylinder stops rotating to complete a printing process.

4. One-rotary printing press: A printing press in which the printing plate reciprocates once and the impression cylinder rotates once to complete a printing process.

5. Two-rotation printing press: A printing press that completes a printing process by reciprocating the plate table once each time.

6. Reciprocating rotary printing press: the impression cylinder rotates once each reciprocating motion. , a printing press that completes a printing process.

7. Cylinder printing press: The printing plate support body and the transfer body are both cylindrical, and they are fully rotated when completing the printing process.

Classification by the number of printing colors and sides

1. Monochrome printing press: A printing press that prints two ink colors on one side of the paper during a printing process.

2. Two-color printing machine: A printing machine that prints two or more ink colors on one side of the paper in one printing process.

3. Multi-color printing press: A printing press that prints two or more ink colors on one side of the paper in one printing process.

4. Double-sided monochrome printing press: A printing press that prints on both sides of the paper during the printing process.

5. Double-sided multi-color printing machine: a double-sided printing machine that prints two or more ink colors on at least one side of the paper during a printing process.
