How to Properly Select and Use Eco-Friendly Printing Blankets
When implementing green printing, one of the first areas that printing companies must focus on is the choice of consumables. In recent years, various eco-friendly printing materials — including green printing blankets, alcohol-free fountain solutions, and water-based adhesives — have become part of the sustainable procurement process for environmentally responsible printing houses.
What Is an Eco-Friendly Printing Blanket?
The green printing standard specifies that inks, varnishes, printing blankets, and other raw and auxiliary materials must not contain six phthalate esters: DINP, DNOP, DEHP, BBP, DBP, and DIPD.These are fat-soluble, synthetic organic compounds that can pollute the environment and pose health risks.
To ensure compliance, printing companies usually request environmental certifications from their material suppliers. According to the Ministry of Environmental Protection and the State Administration of Press, Publication, Radio, Film, and Television, suppliers must provide SGS test reports and Safety Data Sheets (SMDS) proving that their products are free from the restricted phthalates.
For printing blanket manufacturers, this means:
- Avoiding the use of restricted phthalates in raw materials
- Implementing waste gas, wastewater, and solid waste treatment
- Controlling production noise levels to meet green manufacturing standards
How to Select the Right Eco-Friendly Printing Blanket
Although the production process of eco-friendly printing blankets differs from conventional ones, their use on press is very similar. Here are two key points for choosing the right blanket:1. Performance Expectations
Look for good ink transfer, smooth solids and tonal balance, good sheet release, resistance to surface cracking, proper resilience for coating, easy removal of paper edge marks, and smooth paper feeding.
2. Suitability and Brand
Choose a blanket that matches your press conditions first, then select a reputable brand known for consistent quality.
Tips for Using Green Printing Blankets
To achieve the best printing results, pay attention to these four aspects during use:1. Correct combination of blanket packing materials
2. Proper total blanket thickness
3. Correct installation and tensioning
4. Regular cleaning and maintenance
By following these guidelines, printing companies can reduce environmental impact while maintaining high print quality — a key step toward sustainable printing.
