The use of UV inks printing accessories requirements

Many vendors will Referral UV inks a standard, such as a blanket or material selection Ding nitration Acer nitrification can cooperate oil, UV ink or varnish materials market. The natural rubber and polymeric oxide material NA UV inks and coatings. EPDM material selection blankets suitable UV inks and coatings, but not for ordinary Oil-based inks. EPDM blankets not use petroleum refining lotion should purchase special lotion. Select the printer's ink roller is the principle, not often convert UV inks and oil-based inks are generally assumed to be converted is necessary to remove all residual chemicals. UV light and strong enough to make prints of UV ink or varnish completely monotonous, it is necessary according to the printing speed, the ink film thickness and ink color may be. UV light equipment must take into account the type of printer and printing products and equipment suitable for the UV lamp. BASF in UV inks and coatings planning, application of appropriate "industrial pressure mercury lamp" or "microwave H bulb." Assume that the first color is blue, printed ink film thickness (1.20-1.40gm2) at a speed of 100 m / min, it should be applied in two 120Wcm pressure mercury lamp. Assume the high color density, darker color printed on one or two overlapping color, will add a whole monotonous difficulty, which is quickly absorbed UV light formed by dark ink. Usually four-color UV ink level of difficulty in order, is monotonous magenta, yellow, cyan, black central China. So order UV colorful printing shall be black, cyan, yellow, magenta. Opaque color is also very difficult, it is the UV light is reflected back. Metallic colors, gold, silver also have the same questions. Aged lamps can not be too monotonous UV ink or varnish to form printing difficulties. UV lamp must be replaced in the use of 1000 hours, assuming you can not feel the normal printing speed drab prints it is necessary to consider replacing the UV lamp, to prevent the impact print job. No reflector installed by approximately 80% of the UV rays due to diffuse and less effect on the print product, and therefore it is necessary to install a UV lamp shade reflection to meet the focus on prints. Reflector necessary to clean and timely maintenance, to maintain its function best materials market. Some fines or dusting paper dust attached reflective cover, will affect the effectiveness of UV light reflected UV lights when not in use, it should be UV shade closed.
