UV offset fast ink manual
Product name: UV offset fast ink
Model: DSK3820N series
Packing: 1KG/ can
I. Introduction of product features:
DSK3820N series ink is a UV offset printing fast ink, light grade ≥6, this product is mainly used in paper absorbent substrate, with a wide printing water range and on-machine safety; After printing, after UV lamp irradiation, instant curing can be immediately processed, no back printing or sticky problems; Good adhesion with most absorbent substrates; High color intensity, high fullness, good ink transfer, provide good dot definition; VOC meets the requirements of national cigarette pack control and can be directly used in high-end products such as tobacco and alcohol packaging. In addition, this product gives the print more flexibility, higher transparency, more suitable for printing on laser gold and silver cardstock.
Second, technical parameters:

Third, the use of technology:
1, printing method: offset printing (ink bucket type) : printing speed 8000-13000 RPM.
2, drying method: UV curing, it is recommended that 18KW×3 UV lamps, curing energy above 90mj/cm2.
Iv. Precautions:
1, DSK3820N series ink can be used directly, can not add ordinary ink additives.
2, reduce the viscosity can add 1-3% of the ink oil for dilution.
3, reduce the color concentration can be appropriate to add the corresponding diluent, stir evenly, to achieve the desired effect.
4, increase the hiding power or dilute the color brightness can be adjusted by adding white ink.
5, for increasing scratch resistance requirements, 0.5-1% of our special scratch resistance agent can be added to improve the adhesion and scratch resistance of the ink.
6, standard curing conditions: 18KW*3 lamp, lamp distance 10-15cm (depending on the reflector), the total light intensity ≥90mj/cm2.
7, the use of UV ink printing press must use special UV ink or ordinary dual-purpose rubber blanket and ink roller.
8, ordinary cleaning agent can not be used to clean UV printing machine, must use special ink special cleaning agent.
9, black absorbs more ultraviolet light, generally placed in the first color printing, it is recommended that the color sequence is better from deep to light.
10, ink storage environment temperature to 15-25℃ is appropriate, storage period is 12 months.
11, UV ink use as far as possible not to contact with the skin, if the stick should immediately wash with soapy water.
