UV Ink February 3 should have been known to use things - Mexican roll, or resin Plate Blanket
The use of UV ink or UV Varnish may lead to a general printing ink roller, or resin Plate Blanket swelling, enlargement will have more serious peeling or surface cracking or choose appropriate using a special UV and resin version Blanket is very important.
Many chambers of commerce UV Ink Availability of a standard, such as nitrification Blanket or using a nitrification D BenQ may be able to cope with the oily material, or UV Ink Varnish. While natural rubber and polymerization of ethylene oxide material will be enlarged, can not be applied to UV Ink and Varnish.
EPDM material by the Blanket particularly suitable for UV Ink and Varnish, but may not be suitable for the general Oil-based ink. EPDM Blanket Special can not use the oil refining lotion should buy special lotion. Similarly, the choice of printer ink roller is the basis of this principle. Not often transform interchangeable UV ink and general oily ink, if necessary clean-up needs transform Ink very clean, removing all possible residues of chemicals.
UV lamp
The number and intensity of UV light enough to print the UV Varnish ink or completely dry necessary to see the printing speed, ink film thickness and the degree of shading and color ink set. UV lamps are typical installation will consider the type and the printing presses of the finished product to install suitable UV lights.
BASF's UV Ink and Varnish design, the use of a suitable standard "Industrial use of pressure" or "H microwave lamp." If a monochrome (such as green), the printing ink film thickness standards (1.20-1.40 g/m2) in the speed of 100 m / min in, should use two 120 W / cm of pressure mercury lamp. If the high concentration of color, dark colors printed on one or two stacked color, the Special will increase overall drying difficulty, as the UV Ink will soon be ridden absorbed by the pigment. The general four-color UV ink dry difficulty followed by magenta, yellow, green and black. Therefore UV color printing for the order should be black, green, yellow, magenta. Some of the deployment is extremely difficult drying color, such as yellow and green from the green from the deployment; opaque color is very difficult, because it is the UV reflectance returned. The same color metal, gold, silver also have the same problem. UV life restricted, usually manual will tell us its maintenance and life, and the replacement time.
Not too dry aging lamp UV ink or Varnish will cause printing problems. UV lights on most of the manual instructions necessary for the replacement of about 1,000 hours of UV light, in fact if you think that the normal printing speeds drying print is not necessary to consider the replacement of UV lamp, so as not to affect the overall printing operation.
Reflex Cover
If there is no reflex enclosures installed by approximately 80% of the UV light, but not because of the diffusion of printing, therefore necessary to install UV lamps and lamp door reflection of concentrated focus on the direction of printing, reflecting the importance of cover should not be overlooked.
Reflex hood cleaning and maintenance is necessary, would be best to maintain the same and the new functionality. Some paper or the dusting attachment of dust cast in the reflection will affect the UV light reflection effect, an often time not to use UV light, UV lamp door should be closed to prevent dust.
