    In the following sections, we will talk about UV technology. First, we will talk about the characteristics of UV light source, the use of UV technology, UV ink, UV equipment, and the market pattern that needs to be separated when UV technology is put into the future.

    First, the characteristics of UV light source

    The UV light source has a wide range of wavelengths and can be divided into three parts as shown in the figure. According to my previous practical experience, the wavelength is best when the UV-A area is about 360mm.

    Second, the characteristics of UV ink

    To use lithographic UV printing technology, it is impossible to use general inks, and it is necessary to print with specific UV inks. The main components of UV inks include pigments, oligomers, monomers, and photoinitiators. (Photoinitiator) is a sensitizer, a auxiliaries (Filler), and the like.

    Ink is the most critical factor that directly affects the quality of UV printing. In addition to affecting the traditional quality factors such as color expression and color gamut, the printability of the ink affects the adhesion, strength, and abrasion resistance of the printed matter of the printed matter.

    UV inks have the following characteristics

    (1) It needs to be irradiated with ultraviolet light source to dry.

    (2) It will not dry on the printing machine or on the plate before it is irradiated.

    (3) No skinning in the ink tank.

    (4) It will change under high temperature and high humidity and should be kept below 20 degrees Celsius.

    (5) It cannot be mixed with general ink.

    (6) Diluents and cleaning agents shall be used exclusively or in combination.

    (7) UV inks are not common to all materials, and their adhesion must be tested individually according to the different properties of the ink.

    Factors affecting UV drying

    (a) the color of UV ink

    (2) Thickness of UV ink

    (3) Different types of materials to be printed

    (4) The speed of mechanical speed

    (5) Types of UV reflectors

    (6) UV lamp strength

    Third, the scope of UV printed matter

    In general, UV is not specifically used for lithography. It is a kind of UV light source that illuminates chemicals and chemically reacts to produce glue hardening. It is generally called UV hardening. UV hardening can be used in various traditional printing formats, including Printing on letterpress, elastic letterpress, lithographic, screen, etc., so UV technology can print a wide range of paper printing, plastic printing, tape printing, printed circuit boards, chrome printing, electronic parts printing, metal surface printing, aluminum foil printing, etc. It can be said that except that air and water cannot be printed, the rest can be printed.

    Fourth, the economic benefits of UV equipment

    As competition is gradually increasing, in addition to high quality, printing requirements that are more environmentally friendly and cost-reducing will become increasingly important.

    Therefore, the economic benefits brought by the introduction of UV technology, such as increased production, shortened delivery time, space saving, sharp print quality, improved working environment, increased product accuracy, solvent resistance, scratch resistance, electricity savings, ink The waste of crusts and so on. Both help the industry to reduce costs and improve quality, while at the same time meeting environmental needs.

    V. Conclusion

    Judging from the current domestic and international business competition environment, the business problems arising from the price reduction competition of lithographic printers are basically easy to introduce UV printing technology to improve the company's own competitive advantage, as long as it can separate the market and formulate the correct strategy. , lock the target and then invest in it. Rather than blindly buying mechanical equipment, you can bring unlimited business opportunities.
