1、 Definition of UV printing and screen printing
1. UV printing refers to the printing method using UV cured ink. UV ink contains photosensitizers. When exposed to specific wavelengths of ultraviolet light, the chemicals in it activate, causing the ink to solidify and enabling printing.
2. Screen printing refers to the printing method performed using a screen printing machine. By applying a certain amount of pressure on the screen, the patterns on the silk screen fabric are squeezed onto the screen support body.
2、 Technical Principles
The principle of UV printing technology is mainly to cure UV ink after it fully absorbs ultraviolet light, thereby achieving ink adhesion and drying.
2. Silk screen printing is a process of squeezing the patterns on the silk screen to attach to the support body, and its drying mainly relies on moisture in the environment or artificial hot air drying.
3、 Applicable scope
1. UV printing Transfer Stickers are suitable for surfaces of various materials, such as glass, metal, plastic, paper, etc., and have a wide range of applicability. 2. Silk screen printing is suitable for various support surfaces, especially for printing uneven or small patterns.
4、 Difference
1. Printing effect: UV printing transfer stickers have a faster curing speed, resulting in a more stable printing effect and bright and full colors; However, silk screen printing may have color differences or uneven colors due to the material used.
2. Production efficiency: Transfer Logo stickers does not require plate making fees and can be produced directly, with fast speed, suitable for small batch production; And screen printing requires plate making, which has a high cost and is suitable for large-scale continuous production. 3. Environmental friendliness: The curing process of UV printing is completed by UV irradiation, so no organic waste gas is generated; However, silk screen printing may have the problem of solvent evaporation, which has a certain impact on the environment.
4. Cost: The cost of UV printing equipment is relatively high, but the ink can be reused, making the cost relatively low; The cost of screen printing equipment is relatively low, but there are more screen consumables, resulting in a relatively high overall cost.
In summary, both custom UV Transfer Stickers and screen printing have their own characteristics and application scenarios. The choice of printing method should be based on actual needs. When choosing a printing method, factors such as product material, production efficiency, environmental friendliness, and cost should be fully considered. Meanwhile, for different printing needs, two printing methods can also be combined to achieve better results.
