Nine major printing methods for thin films

There are many packaging printing methods for printing films. The common one is solvent ink intaglio printing. Here are nine printing methods for printing films to see their respective advantages?

1. Solvent ink flexographic printing
Solvent ink flexographic printing is a traditional printing method with good quality. Due to the low surface tension of solvent ink, the requirement for film surface tension is not as strict as other inks, so the ink layer has strong firmness and the process is relatively simple. However, solvents affect environmental protection and are harmful to human health, making them a printing method that is about to be phased out.

2. Combination printing
Combination printing, also known as composite printing, is currently the most advanced printing method in the packaging and printing industry in the world. According to different pattern designs, use several methods to print on the same pattern to achieve the best visual effect.

3. UV ink embossing
UV ink embossing is a printing process with good printing quality, high efficiency, and is the most developed and suitable for China’s national conditions. Due to the general lack of UV devices in domestic embossing equipment, thin film printing is limited, so equipment updates and modifications are essential conditions for printing thin films.

4. UV ink flexographic printing
UV ink flexographic printing has a high cost, but the requirements for film surface tension are relatively not strict. Generally, manufacturers use water-based ink printing, and UV polishing can reduce costs and increase printing efficiency.

5. UV ink screen printing
UV ink screen printing is a new process that can be printed on single sheets or rolls, with high cost and good quality. Single sheet printing does not need to be hung for drying, and roll printing can be carried out at high speed.

6. Water-based ink flexographic printing
Water-based ink flexographic printing is the most advanced printing method in the world today, with low cost, good quality, and pollution-free. But the process requirements are strict, and the surface tension of the film must be above 40 dynes. There are strict requirements for the pH value and viscosity of the ink. This process is a vigorously developed process in China, but it has been slow to develop due to equipment limitations.

7. Solvent ink screen printing
Solvent ink screen printing is a traditional process that typically involves manual printing of individual sheets and printing of roll materials using a linkage machine.

8. Intaglio printing
The quality of gravure printing is the best among all printing methods and is also a commonly used printing method in domestic soft packaging factories.

9. Ordinary resin ink printing
Ordinary resin ink printing is the most commonly used method. Due to drying issues, there are two drying methods: cutting individual sheets and hanging them for drying. This method has a long drying time, a large footprint, and is prone to scratching and laminating. Wrap the dried ink between the films and be careful not to apply lamination to prevent lamination failure.
