Description
Technical field
The invention belongs to driography plate-making field, relate to the primary coat liquid for driography plate-making and application, and the preparation method of the primary coat liquid of this driography plate-making.
Background technology
Driography technology because anhydrous and fountain solution participates in, has not relied on ink-water balance principle since proposing from 1931, thus printing precision and press resistance rate excellent.Driography has the following advantages: 1) dot reproduction is good.The site of high light part 2% and the site of shadow part 98% of 200 line to 500 lines can be reproduced well, and the details of shadow part and level can clearly reproduce out.Driography printed matter is 96% from the dot reproduction rate of 2% to 98%, and has the dot reproduction rate of water offset prints from 5% to 95% to only have 90%.2) mass colour is consistent, and glossiness is good.Driography technology causes the printed matter mass colour phenomenon caused not of uniform size without the fluctuation because of ink-water balance.After printed matter drying, layer of ink is abundant, bright in luster, steady quality.3) dot gain is controlled.Because driography technology does not have the impact of fountain solution, so dot gain value only has 7%.And have water offset printing net bag method to be more than 10 ~ 15%.4) chromatography is accurate.Driography technology, due to anhydrous impact, so can not cause paper striction phenomenon, thus ensure that the chromatography of printing is accurate.5) pressrun of forme is high.The press resistance rate of sheet-fed driography technology can reach 100,000 prints, and the press resistance rate of rotary cylinder driography technology can reach more than 150,000 prints.6) forme plays print soon, can save examination printing paper.7) printing efficiency is high, shortens the production cycle.Adopt driography technology to improve the quality of products, and decrease because ink-water balance fluctuates the adjustment and stop time caused, shorten the production cycle.8) color space is large, because driography technology can print out higher ink density (higher by about 20% than there being the ink density of water offset printing), therefore the color space of driography technology is larger than there being the color space of water offset printing.Use high screen density printing, more heavy wool ink can be shifted on paper, also can increase color space.9) scope of undertaking the printing of is wide, and owing to not having the participation of fountain solution and water, paper distortion is little, and alignment precision is high, so driography technology can print out high-quality printing on offset paper and recycled writing paper.For non-absorbent stock (as plastics film, metal, synthetic paper etc.), driography technology also can ensure printing quality preferably.10) frequency modulation technology can be adopted.The site size of modulating net is consistent, and because driography technology dot reproduction is good, therefore, modulating net technology is suitable for driography.11) easy to operate.Because driography technology thoroughly solves the fluctuation of difficulty and the quality product brought to operator due to this changeable factor of ink-water balance, thus operate waterless offset press very convenient.12) save material, reduce environmental pollution.Can not dampening system be used during driography technology print, bucket solution, protecting glue can be saved simultaneously, make environment not contaminated.13) water resources protection, anhydrous printing can water conservation.Along with the enhancing of global range environmental consciousness, press adopts driography technology to be significant.
In current world wide, waterless offset press about 3000, mainly concentrates on the developed countries such as the U.S., Canada, Germany, Japan.According to statistics in 2009, the driography share of market in Europe was 6 ~ 7%, and the U.S. is that 5 ~ 6%, Fogra institute report driography share of market will increase to about 10%.Asia is except the driography share of market of Japan is higher, and also there are a small amount of application in Taiwan and some countries of South East Asia.In China except there is experimental use on the ground such as Beijing, then do not have other local use, share of market is almost nil.Mainly plate production domesticization is unresolved for the reason that driography technology is not in progress in China, exceeds 3 ~ 4 times of place of production price from the price of Japanese import plate.Anhydrous offset plate eliminates the treating processes such as electrolysis, anodic oxidation, decreases environmental pollution, and improves press resistance rate and must research and develop the undercoat be combined with sensitive layer by version base.
Toray company (JP1237551A) was once used alone epoxy resin, urea resin, terpolycyantoamino-formaldehyde resin, vibrin and dyestuff or pigment combinations as undercoat, improve exposure latitude, and press resistance rate did not have clear improvement; Then the unsaturated hydrocarbons compounds (JP8211594A) by introducing sulfur-bearing improves the reproducibility of press resistance rate and image.Primary coat liquid of the present invention can make an edition bonding mutual between base and sensitive layer combine closely, and with the pollution reducing electrolysis, anodic oxidation causes, the mode of photocuring can effectively be enhanced productivity.
