1, UV ink UV ink drying ink using ultraviolet radiation to the principle of film through the chemical reaction after illumination, Mexico and the photosensitive material (monomer) received UV energy, stimulating and bonding with the paint cross-linking.
UV ink are used for high-end foreign goods Package And fine Print Goods in total or partial coating, can show raised, wrinkled, foam, matte, precious stones, refraction, varnishes and other visual effects, gives a gorgeous, stately, elegant sensory impressions.
UV ink drying quickly, in a standard UV energy, usually more than 10 seconds can be drying. UV ink also excellent abrasion resistance, can reach 15 million times, 5-6 times higher than normal ink.
In use should be noted: need to use special ink roller and Blanket ; Print shop to maintain 22 ± 3 degrees Celsius; printing UV ink to the regular full mix, always concerned about the water, ink balance; can not be mixed with other inks; ultraviolet radiation to the standard, to install reflectors; at 25 degrees Celsius from light, not long-term storage; on printing workers hurt, workshop attention to ventilation, operators wear overalls, gloves, wear sunglasses; limit Food The UV ink used within the packaging.
Substrates using UV ink crease when folded, the current high prices.
2, ink color temperature Appearance of color patterns: at low temperatures, non-ferrous, high temperature colorless. To choose the color red, red, pink, red, orange, yellow, green, grass green, sky blue, Turkey blue, blue, dark blue, black, etc..
Set temperature range: from -15 degrees Celsius to 75 degrees Celsius. According to the different needs of various products, in different temperature range. General color temperature setting range from 2 degrees to 10 degrees Celsius, color density gradually decreased from low to high, until almost transparent.
3, photographic color ink Appearance of color patterns: light-sensitive color ink-printed product in the sun (UV) irradiation, due to ink absorption of sunlight (UV) energy resulting color change; loss of sunlight (UV) irradiation, then returned to the original color .
Basic four colors: colorless? Red and colorless? Purple colorless? Blue colorless? Yellow
4, luminous ink Luminous luminous paint must absorb all visible light, which store solar energy, and can automatically light in the dark, and can be infinitely recycled.
In use should be noted: Need to use neutral or weak alkaline transparent resin, mixed use;
Need high-speed stirring dispersion of raw materials, preferably glass or ceramic containers for storage;
The length of storage time, depending on the amount of water content, pay attention to moisture. Too much moisture, easy to darken or form lumps;
Luminous powder to reduce the precipitation, to use the high viscosity of the resin, or the anti-settling agent added, and stir before use. Diluent used to adjust the viscosity, do not use heavy metal compounds Additive ;
Order to improve the printed map of the brightness and light-emitting time, printing the background color should be mainly white or reflective;
Screen Printing, to obtain a better luminous effect of mesh size 80? 120 mesh was the best;
