In China, more and more newspaper printing enterprises choose to use UV resin technology and equipment for production. Its technical advantages mainly include the following: fast drying and high density; Online printing of advertisements; Can print book cover on coated paper; Can print on magazine paper; The insert can be preprinted; It can increase the commercial attraction of newspapers; Add value to existing products.
These technical advantages make UV resin printing technology become the main means for some newspaper printing enterprises to achieve business growth and income increase in the current depressed economic environment. In some cases, UV resin technology can help users recover their investment as quickly as possible. As publishers tighten their money and stop investing in large rotary presses, they are likely to turn their attention to technologies with high return on investment such as UV resin printing.
Although some printing plants have a large amount of surplus capacity, they still take some live parts to the printing plant with thermosetting printing machine for outsourcing processing, which forms a great waste. Although the price of UV resin printing ink is more expensive than ordinary thermosetting ink, under the condition of certain circulation, the advantages of UV resin printing technology in logistics and printing cost are very obvious. Even though the price growth of thermosetting ink has always been consistent with the price of crude oil and is currently at a high level, there is still a certain distance from the price of UV resin ink because of its high purity – and thermosetting ink contains at least 40% solvent.
However, in order to successfully integrate UV resin technology into the existing production line, many technical parameters need to be considered, such as the overall increase of ink cost, different rheology from other inks, different chemical properties, etc., which will put forward some new requirements for the setting of ink conveying system, ink roller and rubber cloth.
In addition, UV resin printing technology also has many advantages that thermosetting printing technology does not have, which makes it an ideal substitute for traditional newspaper printing technology: no blistering; Post incinerator is not required; The printed matter will not shrink under heating and does not need secondary humidification; No moire; It will not cause the warping of paper fibers; It will not rub dirt on the guide roller, folding machine, conveyor belt and mailing equipment of the printing machine; Printing scratch will not occur in the dryer; It will not make the product and paper roll ripple; The floor area of its drying device is smaller than that of HS dryer; There is no need to change the direction of the wet roll.
