Now we will talk about UV technology in several parts. First of all, talk about the characteristics of UV light source, the use of UV technology, UV inks, UV equipment, and the market structure that needs to be separated in the future.
One, UV light source characteristics
The UV light source has a wide wavelength range and can be divided into three parts as shown in the figure. According to my previous practical experience, the wavelength is about 360 mm in the UV-A area.
Second, the characteristics of UV ink
To use lithographic UV printing technology can not use the general ink, must be printed with a specific UV ink can be printed, the main component of the UV ink contains pigment (Pigment), quasi-polymer (Oligamer), monomer (Monomer), light initiator (Photoinitiator) is a sensitizer, a filler, and the like.
Printing 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 performance and color gamut, the printability of ink also affects the adhesion, strength, and anti-friction force of printed materials that are printed.
UV ink has the following characteristics
(a) It needs to be irradiated with ultraviolet light to dry.
(b) It will not dry on the printer or on the plate before it is irradiated.
(c) No skinning in ink tanks.
(d) Changes will occur under high temperature and high humidity and should be kept below 20 degrees Celsius.
(e) It cannot be mixed with general inks.
(6) Diluents and cleaning agents shall be used exclusively or concurrently.
(7) UV inks are not universal for all materials, and their adhesion must be tested individually according to the nature of the ink.
Factors Affecting UV Drying
(a) the color of UV ink
(B) The thickness of UV ink
(3) Different types of printed materials
(d) The speed of mechanical speed
(five) UV reflector types
(6) UV lamp intensity
Third, UV printing range
In general, UV is not specifically used for lithography. It is a UV light source that irradiates chemicals and produces a glue-hardening reaction by chemical reaction, commonly known as UV hardening. UV hardening can be used in various conventional printing formats. Relief printing, flexographic printing, lithography, screen printing, etc., so UV technology can print a wide range such as paper printing, plastic printing, tape measure printing, printed circuit boards, chrome printing, electronic parts printing, metal surface printing, aluminum foil surface printing, etc. It can be said that except that air and water cannot be printed, the rest can be printed.
IV. Economic Benefits of UV Equipment
As competition has gradually increased, the demand for printed materials will be increasingly important, in addition to high quality, printing methods that are more in line with environmental protection needs and cost reduction.
Therefore, the introduction of UV technology can bring economic benefits such as increased production, shorter delivery time, space saving, high printing quality, improved working environment, increased product accuracy, solvent resistance, scratch resistance, electricity savings, ink is not Crusted waste and so on. All help the industry to reduce costs and improve quality, and at the same time meet the needs of environmental protection.
V. Conclusion
Judging from the current competitive environment at home and abroad, the operating problems caused by the price cut competition of the lithographic printing industry are basically very easy if you want to introduce UV printing technology to improve the company's own competitive advantage, as long as you can distinguish the market and formulate the correct strategy. , lock the target and then put it all together. Instead of blindly buying machinery and equipment, it will bring unlimited business opportunities.
