GB/T 3264-2010 in English

1. Standard background and revision notes

GB/T 3264-2010 "Printing Machinery Sheet-fed Lithographic Printing Machine" is a comprehensive revision of the original standard GB/T 3264-2005. The main changes include:

• Updates to terms and definitions, and adds a definition of maximum printing speed.
• Adjustments to types and basic parameters, and divides them into high-speed machines and medium-speed machines according to printing speed.
• Strengthening of printing accuracy indicators, adding key parameters such as dot gain value and ghosting.
• Added safety requirements and safety inspection content.
• Integration and optimization of electrical requirements, and supplementation and improvement of test methods and calculation formulas.

2. Comparison of standard frameworks

3. Interpretation of the core content of the standard

3.1 Terms and definitions

The standard defines several key terms, such as paper feeding accuracy, paper transfer precision, etc. The accurate definition of these terms provides the basis for subsequent technical requirements.

3.2 Types and basic parameters

Printing presses are divided into high-speed and medium-speed types according to their speed. Specific parameters include:

• Maximum paper size: 1000X1400mm for high-speed presses and 700X1000mm
• Printing speed range: 15,000 sheets/hour for high-speed presses and 10,000 sheets/hour
for medium-speed presses

3.3 Safety requirements and protection

Newly added safety requirements include:

• The protective device at the roller inner rotation and winding part shall have a gap of not less than 6mm
• Fixed protective sleeve of the paper feeder nozzle drive shaft
• Emergency stop button function test: inertia rotation number does not exceed 2/3

4. Implementation suggestions and application cases

4.1 Standard implementation suggestions

When implementing the standard, enterprises should focus on:

• Equipment selection: select the appropriate model according to printing speed and paper size
• Safety protection transformation: ensure compliance with the new version of safety requirements
• Regular maintenance: check the lubrication system and transmission system according to standard requirements

4.2 Application case analysis

During the equipment upgrade process, a printing factory significantly improved its printing efficiency and product quality by adopting high-speed printing machines in accordance with the GB/T 3264-2010 standard. In particular, the dot gain value was controlled within 20%, effectively ensuring the color reproduction.
