Energy Curable Ink Introduction: UV Ink and EB Ink

What is energy-curable ink?
Inks that are cured using UV light and accelerated high-energy electron beams (EB) are called UV inks and EB inks, respectively, and are collectively referred to as energy-curable inks.

What are the advantages of energy-curable inks?

(1) Save manpower: The energy curing ink has a fast curing speed (printing speed can reach 100-300 meters/minute, and the fastest speed exceeds 500 meters/minute), so when the printing sheet leaves the printing press, it can be directly overprinted, which saves costly Drying, drying and other procedures save a lot of manpower.

(2) Shorten the standby time: The energy-curable ink does not adhere to the ink roller, so it is not necessary to clean the ink roller and improve the production efficiency.

(3) Save floor space: From traditional printing to UV/EB printing, valuable factory floor space can be saved. Since the ink is cured immediately after passing through the curing device, no drying or drying system is required, saving floor space.

(4) Improve production efficiency: UV/EB inks are superimposed on high-speed production lines, so that the production efficiency depends entirely on the printing speed and is no longer limited by the drying speed.

(5) Broaden the scope of printing: UV/EB inks can adhere well to almost all materials, such as polyethylene, vinyl, styrene, polycarbonate, glass, metal, and paper.

(6) Suitable for heat sealing, die cutting: UV/EB ink does not fall off due to heating and is suitable for printing tough, heat-sealed vinyl materials.

(7) Good abrasion resistance: UV/EB ink film has very good abrasion resistance and can eliminate powder off.

(8) High product quality: Energy-cured inks can be instantly cured, with small dot gains. The ink does not penetrate into the paper, resulting in discoloration after drying. Therefore, the quality of the printed matter is excellent, and the color saturation, color intensity, and sharpness are all significantly better than those of ordinary materials. Ink. In addition, printed materials have very good chemical resistance and physical properties. This suitability makes it suitable for printing products that need to be used in harsh environments and that require high chemical stability.

(9) Energy Conservation: Energy-cured inks are very energy sensitive. Compared to traditional inks, their energy consumption is lower.

(10) Environmental compliance: Energy-curable inks do not contain traditional solvents. Because the organic components of the ink are almost completely confined to the polymerization process, no volatile organic components will disperse to pollute the air.

What is the difference between EB ink and UV ink?

As energy-curable inks, EB inks and UV inks have many advantages, but when printers decide to choose energy-curable inks, they do not know how to choose between EB inks and UV inks. What is the difference between EB ink and UV ink?

(1) Printing quality: Compared with UV inks, EB inks are more fully cured, in particular, the solid ink film is more completely cured, and has nothing to do with the ink color and ink film thickness; the odor is small; curing will not lead to printing The deformation of the heat.

(2) Application: In food packaging and printing, EB ink is more widely used, because its printing effect is more stable and uniform, reproducibility is good, and there is no photoinitiator in the ink composition, the print smell is small, the ink in the Less component migration. However, the application of EB ink is still limited to the field of rotary printing.

(3) Ink cost: In general, the cost of EB ink is slightly higher than UV ink. Because of the high purity of raw materials, low odor EB inks can be obtained, so the price of highly purified raw materials is higher. At the same time, laboratory analysis of the purity of raw materials and finished inks is also one of the cost factors to be considered. However, with EB ink printing, the production efficiency is higher and the printing speed can be as high as 3000 feet/minute.

(4) Supporting equipment: Relatively speaking, the operation and maintenance of EB curing equipment requires more capital investment. Since the curing of the EB ink must be in an inert atmosphere, nitrogen is needed for curing, the space for the EB curing device and the nitrogen container is limited, and the capital investment is large. EB curing equipment is not suitable to be installed between the units of the multi-color printing press, otherwise the equipment cost is higher. Some printers install UV curing units between the units and EB curing units at the end of the printer. Compared with EB curing systems, UV curing devices are complex and difficult to maintain.

The raw materials that make up a mop are various. However, microfiber yarn and Cotton Yarn are the most common styles on the market.

 

Microfiber is a polyester and nylon fiber that is used to make fabric. The fiber is many times smaller than a human hair; when woven together, the fibers create a net-like surface that traps more dirt, debris and moisture than cotton.Microfiber is simply a superior cleaning material.Cotton recycling prevents unneeded wastage and can be a more sustainable alternative to disposal.

 

Recycled cotton may come from older, previously used garments or by textile leftovers which are then spun into new yarns and fabrics.Even though recycling cotton cuts down on the harsh process of creating brand new cotton products, it is a natural fiber and is biodegradable, so any cotton fibers that cannot be recycled or used further can be composted and will not take up space in landfills.
