What is the difference between UV printing and screen printing
Date: Aug 30 2024 From: Star Color
In the printing industry, UV printing and screen printing as two important printing technology, each with unique features and advantages.
First, the principle of printingUV printing: UV printing is a printing method that uses ultraviolet radiation to cure ink. In the printing process, UV ink is printed on the substrate, through the irradiation of ultraviolet light source, the ink in the photosensitizer chemical reaction, so that the ink quickly cured on the surface of the substrate.
Screen Printing: Screen printing is a printing method that utilizes a screen as a printing template and scrapes the ink onto the substrate through a squeegee. In the printing process, the ink leaks through the holes in the screen to the substrate, forming a pattern. The precision of screen printing is relatively low, but the cost is also low, applicable to a variety of shapes and materials of the substrate.
Second, the type of inkUV ink: UV ink is a kind of light-curing ink, with fast curing speed, bright colors, wear-resistant and scratch-resistant, etc. There are many kinds of UV ink, including fluorescent ink, glossy ink, fast-setting ink, etc., which can be selected according to different printing needs.
Screen printing inks: Screen printing inks, on the other hand, include water-based inks, solvent-based inks and many other types. The selection of these inks mainly depends on the material of the substrate and the demand for printing effects. For example, for textiles and other substrates that require a soft touch, usually choose water-based inks; for metals and other substrates that require high adhesion, then choose solvent-based inks.
Third, the scope of applicationUV printing: UV printing has a very wide range of applications and can be used for almost all types of materials, including plastic, metal, glass, paper, etc.. Its excellent printing results and durability make it the preferred printing method for high-grade packaging, commercial albums, special labels and other fields.
Screen Printing: Screen printing, on the other hand, is more suitable for small-lot printing of flat or irregular shapes, such as T-shirts, automobile glass, handicrafts and so on. Due to its low cost and adaptability, screen printing has a wide range of applications in daily life and industrial production.
Fourth, the cost and efficiencyCost: From a cost perspective, the cost of UV printing is usually higher than screen printing. This is mainly because UV printing requires the use of special UV ink and UV curing equipment, and the acquisition and maintenance costs of these equipment are relatively high. In addition, plate making costs for UV printing may also be higher, especially for small print runs.
Efficiency: UV printing has the advantage of being efficient and fast. Due to the fast ink curing speed, UV printing can complete a large number of printing tasks in a short period of time. And screen printing, although the process is simple, but relative to UV printing, its printing speed may be slower, especially in the need for frequent changes in color and pattern.
Five, the printing effectUV printing: UV printing printing effect is very excellent, bright colors, distinctive levels, clear details, UV ink curing effect makes the surface of the printed material is smooth, wear-resistant and scratch-resistant, with good visual effects and tactile sensations.
Screen Printing: The printing effect of screen printing is relatively simple, and its color saturation and precision may not be as good as UV printing. However, screen printing has a unique advantage in printing large-area patterns or irregular shapes, which can achieve better coverage and uniformity.
Sixth, environmental protectionWith the improvement of environmental awareness, the environmental protection of the printing industry is also increasingly concerned about the UV printing and screen printing in the environmental protection have their own characteristics:
UV printing: UV printing using light-curing ink, reducing the use and emission of organic solvents, which is conducive to reducing environmental pollution. At the same time, UV printing process produces less waste, easy to recycle and disposal.
Screen Printing: Screen printing may use solvent-based inks in some cases, and these inks may produce harmful gases and waste liquids in the process.
There are significant differences between UV printing and screen printing in terms of printing principles, ink types, scope of application, cost and efficiency, printing results and environmental friendliness. When choosing the printing method, it should be based on the specific printing needs and the actual situation for comprehensive consideration.
