A print dust-free workshop is a high-purity environment specifically designed for printing activities, capable of effectively removing dust, bacteria, and particles from the air to ensure product quality and hygiene.

Standard requirements for a cleanroom printing facility:

Cleanliness standards

The cleanliness standard for a print-free clean room is generally required to meet the Class 3 standard in GB/T 16292-2008, meaning the air cleanliness inside the workshop should reach less than 35,000 particles/m³ for larger particles (≥0.5μm), and zero for particles (≥5μm).

2. Temperature Standards

The temperature standard for a print clean room should generally be between 22℃±2℃, and can be moderately adjusted according to the requirements of the printing process.

3. Humidity Standards

Humidity standards for a printing dust-free room should generally be between 45%RH and 65%RH, and can be moderately adjusted according to the requirements of the printing process.

4. Differential Pressure Standard

The differential pressure standard for a printing dust-free workshop should typically be no more than 10Pa between the inside and outside.

5. Material Standards

Walls, ceilings, and floors in a printing dust-free room must be constructed with antistatic or conductive materials to ensure the generation and spread of static electricity do not affect print quality.

6. Air Purification Standards

Air purification equipment in a print clean room should be well-equipped, including pre-filters and medium-efficiency filters, and should be regularly inspected and replaced.

7. Standard Requirements for Printing Equipment

Equipment used in dust-free printing workshops must meet cleanliness requirements and be equipped with static elimination devices. Regular maintenance and inspections of the equipment should also be conducted.

A print-free dust-free workshop is the foundation for ensuring print quality, meeting the above standards to guarantee print quality while also enhancing the work environment for employees.
