1. According to the relationship between glazing machine and printing machine, it can be divided into: offline glazing and online glazing.
(1) Offline polishing
Offline glazing adopts a special glazing machine to glaze the printed products, that is, printing and glazing are carried out on their own dedicated equipment. This glazing method is more flexible and convenient, and the glazing equipment investment is small, which is more suitable for professional post-press processing manufacturers. However, this glazing method increases the transportation and transfer between printing and glazing processes, and the production efficiency is low.
(2) Online polishing
On-line glazing directly connects the glazing unit to the printing unit, that is, printing and glazing are performed on the same machine. The speed is fast, the production efficiency is high, and the processing cost is low. The various types of quality failures are the future development direction. However, online glazing has high requirements on glazing technology, glazing oil, drying equipment and glazing equipment.
2. According to the glazing method, it can be divided into: roller coating glazing and printing glazing.
(1) Roller coating
Roller coating is the most common method of glazing. The coating roller applies the varnish on the surface of the printed product evenly over the entire surface.
(2) Printing and polishing
Printing glazing The glazing oil is applied to the printed product through the glazing plate, so local glazing can be performed. Currently commonly used are gravure glazing, flexographic glazing, offset printing glazing and silk screen glazing.
3. According to the classification of glazing products, it can be divided into: full-frame surface glazing, partial glazing, extinction glazing and artistic glazing.
(1) Full surface gloss
The main function of full-surface gloss is to protect the printed matter and improve the surface gloss of the printed matter. The full-surface smoothing is generally carried out by roller coating.
(2) Partial polishing
Partial glazing generally glazes the graphic parts to be emphasized on the printed matter. The high-gloss picture of the glazing part is compared with the low-gloss picture without the glazing part to produce a wonderful artistic effect. Partial glazing is carried out by printing and glazing. The film obtained by screen printing is thicker, the effect is more obvious than other methods, and the cost is lower. At present, it is used more in China, but its production efficiency is generally Lower.
(3) Extinction and glazing
The matte glazing uses UV matte oil, which is the opposite of ordinary glazing. It is to reduce the gloss of the surface of the printed matter and thus produce a special effect. Too high gloss has a certain degree of stimulation to human eyes. Therefore, extinction glazing is a popular glazing method at present.
(4) Art glazing
The role of artistic glazing is to obtain special artistic effects on the surface of glazing products. If UV pearlescent glazing oil is used to polish the surface of the printed matter, it will produce a pearlescent effect on the surface of the printed matter and make the printed matter look magnificent, noble and elegant.
