Abstract
The invention relates to novel Ultra Violet (UV) waterless offset ink which is prepared according to the following steps of: taking 40-50 parts of modified polyester acrylate under the condition of stirring, adding 5-15 parts of urethane acrylate, 5-10 parts of light trigger, 0.1-2 parts of stabilizing agent, 0.1-3 parts of antiwear agent and 0.1-8 parts of rheological additives, stirring at high speed until all the powders are dissolved, adding 15-35 parts of pigment, stirring uniformly, diffusing at high speed for 10-200min, and then grinding and rolling, controlling the fineness to be less than 10mu, transferring to a diffusing barrel after grinding, adding 5-15 parts of epoxy acrylate and diffusing at a high speed for 10-200min. Compared with the traditional UV waterless offset ink, the UV waterless offset ink prepared with the method provided by the invention has the advantages of not needing a fountain solution in the printing process, improving the printing efficiency as well as the color and the quality of a product and also having no pollution to the environment and fire hazard.
Description
Technical field:
The present invention relates to a kind of new ultra-violet photocuring (UV) waterless offset ink, compare with traditional UV flexographic ink, the UV waterless offset ink does not need fountain solution in printing process, improved printing efficiency and product color quality, can not produce environment simultaneously and pollute and disaster hidden-trouble.
Technical background:
In traditional UV offset printing process, pre-coating photosensitive resin plate (PS version) will carry out damping with fountain solution before last China ink, and by damping, fountain solution forms moisture film at the hydrophilic area (non-image district) of PS version, but is shrunk to little water droplet in the oleophylic district of PS version (image area); At this moment, when PS version that the ink roller that contains UV printing ink was handled by damping, it can not go up China ink in the zone (non-image district) that the fountain solution moisture film covers, but can make the little water droplet emulsification in oleophylic district (image area), causes this zone to be coated with printing ink.It is crucial setting up in printing process and keeping the correct printing ink and the balance of fountain solution, and needs very high level of skill.Adjusting has the ink-water balance between glue printing ink and the fountain solution to remain a big problem of puzzlement printing industry so far.In addition on the one hand, traditional glue seal that has has caused water to pollute and disaster hidden-trouble because of reasons such as fountain solutions.
Do not need damping during the waterless offset ink printing, printing ink is China ink in the oleophylic district on the PS version directly, has simplified production process, enhances productivity; Also avoided simultaneously having solved wherein volatile organic matter (VOCs mainly is an alcohol) potential disaster hidden-trouble because the water that reasons such as fountain solution cause pollutes; There is not the phenomenon of floatingization in PS version oleophylic district yet, avoided using fountain solution and the ink emulsification and the form and aspect distortion that produce, reduces the color information of forme more truly, improves the chromaticity of printed matter.
But the waterless offset ink that adopts mostly is non-UV type at present, and printing ink film forming physico-chemical property is poor, and curing speed is slow, and print speed is low.Therefore developing a kind of novel UV waterless offset ink seems rather important.
Summary of the invention:
The present invention is intended to address the above problem and provides a kind of and can solidify at a high speed, can satisfy high quality printing and environmental requirement, does not use fountain solution, does not contain VOCs, can be used for the UV waterless offset ink of label printing or CD printing.Its contribution is to avoid using fountain solution, has reduced the ink-water balance operating procedure in the printing process, has improved production efficiency, has reduced VOCs and the water in the typography and has polluted, and has improved printed matter color quality.
