UV ink in the polymerization initiator to absorb certain wavelengths of light photons, under UV irradiation.Inspire to the excited state, formation of free radicals or ion.Then through intermolecular energy transfer, make polymerized prepolymer and photosensitive monomer polymer become excited, produce the charge transfer complex body;Complexation Hugh crosslinking trestle, curing film.UV ink for ultraviolet photons is selective absorption of UV ink dry under UV light radiation light can always the most and the influence of different wavelengths of light energy distribution.To solve the UV ink and UV light source matching, to speed up the ink dry, further improve the labor productivity and energy utilization, reduce production costs.

     Scraping blade will shift the printing ink from the circular screen version by embossing roller bearing surface of the substrates.The whole printing process in paper, ink, color, alignment, such as UV dry bath by computer full automatic control.Circular nickel screen plate with 100% of non woven material, electroforming forming its wire mesh a hexagonal shape hole, the thin, smooth surface evenly to ensure that the mark is not disorderly and precision.Suitable for large rotary printing, top speed of 125 m/min, roll paper rotary screen printing using nickel metal circular screen plate, built-in scraping blade and automatic ink system.Reusable 15 times.Roll paper, therefore, rotary screen printing can be satisfied printing mill, such as sand, ice, effect, and can online holographic anti-counterfeiting mark, belling, hot stamping die cutting molding, easy to realize high speed automatic carton printing.

       UV printing imitation of metal etching ink rapidly solidified under ultraviolet light irradiation,   environmentally friendly UV screen printing imitation of metal etching ink is mainly composed of oligomer (i.e., light-cured resin) reactive diluent monomer (that is, the photosensitive sex al) light (polymerization), initiator, add an agent.Gold and silver cardboard printing.Print on the surface of frosted effect.

      High-grade alcohol and tobacco, silk screen printing ink layer thickness, graphic level, stereo sense is strong, rich, wide substrates, etc.Food packaging carton applications gradually increase.Using UV screen printing ink, printing frosted on cigarette packets, refraction, ice, wrinkles and other effects, greatly stimulate the purchase desire of consumers.But because the printing speed is low, flat screen printing way ink curing speed, print quality is difficult to control, printing materials consumption is big, can't satisfied the needs of the cigarette carton size, batch production.Using high speed rotary screen printing production lines, printing speed, high yield rate, print quality not disorderly, low consumption, changed the traditional flat flat screen printing, manual for paper, ink, suitable for high speed automatic, and mass produce exquisite folding carton.
