Web-fed rotary screen printing uses nickel metal round screen printing plates, a built-in doctor blade and an automatic ink supply system. The doctor blade transfers the printing ink from the round screen to the surface of the substrate supported by the impression cylinder. The entire printing process from paper feeding, ink supply, color registration, UV dry bath, etc. are all fully controlled by the computer. The round screen printing plate is made of 100% nickel non-woven fabric material, and the mesh hole is hexagonal wire hole formed by electroforming. The entire mesh surface is flat and even to ensure the imitation and precision of the imprint. Suitable for large-format rotary printing, the maximum speed can reach 125m / min, and the screen can be reused 15 times. Therefore, web printing can meet the requirements of special effects such as frosting and icing, as well as online hot stamping of holographic anti-counterfeiting signs, embossing, and die-cutting, making it easy to realize high-speed automatic printing cartons.

Environmentally friendly UV silk screen imitation metal etching ink is mainly composed of oligomer (ie photo-curable resin), reactive diluent (ie photosensitive cross-linking monomer), photo (polymerization) initiator and filler. Printing on gold and silver cardboard, UV screen printing metal imitation etching ink quickly cured under ultraviolet light, the surface of the printed matter produces a frosting effect.

Screen printing has the characteristics of thick ink layer, rich graphic layer, strong three-dimensional sense, and wide printing materials. Its application in high-end tobacco, alcohol and food packaging cartons has gradually increased. The use of UV screen ink to print matte, refracted, ice, wrinkle and other effects on the cigarette case greatly stimulated consumers' desire to buy. However, due to the low printing speed of flat screen printing, the slow curing speed of ink, the difficulty of controlling the printing quality, and the large consumption of printing materials, it is unable to meet the needs of cigarette carton scale and mass production. Using high-speed rotary screen printing production line, fast printing speed, high yield, undisturbed printing quality, low consumption, changed the traditional flat screen printing, manual paper, ink supply, suitable for high-speed automatic, large-scale Mass production of exquisite folding cartons.

Under the irradiation of ultraviolet light, the photopolymerization initiator in the UV ink absorbs photons of a certain wavelength and excites to an excited state, forming free radicals or ions. Then, through the transfer of energy between molecules, polymers such as polymerizable prepolymers and photosensitive monomers are brought into an excited state, and a charge transfer complex is generated; the complex is continuously cross-linked to the stage and cured into a film. UV inks selectively absorb the photons of ultraviolet light, and the dryness of UV inks is affected by the total energy of the UV light source and the distribution of light energy at different wavelengths. Solving the matching of UV ink and UV light source is conducive to speeding up the drying speed of ink, improving labor productivity and energy utilization, and reducing production cost.

The Eyebrow Pencil is a product for shaping the eyebrows. The purpose is to shape the eyebrows with a razor, tweezers, etc., and then use the eyebrow pencil to draw the desired shape to make the eyebrows thick and bright.
The most commonly used eyebrow pencil products are paper refills, wooden pencil-type or mechanical pencil-type eyebrow pencils. The eyebrow pencil refill is composed of pigment dispersed in low melting oil and wax base, kneaded, and then made into a core. The color of the eyebrow pencil is brown, black, and gray. Depending on the skin color, you can choose different shades.
