Printing ink removal and elimination of the causes of roll


Surviving in the subtle difference between the quality, but also resistance, however, restricted from areas of environmental protection reasons, priority should be to roar, so the packaging printing industry more than is necessary to introduce as soon as possible to cope with small quantities and short delivery time of the narrow range of flexo , of the innovative packaging and printing industry. Flexible CIP if further improvements in the development of the introduction of plate seamless way with other layout differ significantly in terms of quality, not only are small quantities, large quantities of printed even be able to cope with living down to Shao, the Council In the early 21st century, the usher in line with environmental protection, but also has high quality and high productivity flexible sampan print, packaging and printing it will undoubtedly become the mainstream. Figure 4F1 both 0pak machine picture @ Golden Galaxy is currently abroad, tend to use E-type post-production color printing corrugated cardboard boxes, multi-layer corrugated cardboard is corrugated layer in the E-type printing, which is conducive to printing pressure evenly, network service level, but also save paper. The three corrugated mostly domestic A-c {or B) corrugated composite; corrugated is the A-B or Bc corrugated composite; seven corrugated is the A-c-B, B-A-B, B-AA , cA-c-type corrugated complex, rarely used E-type E-type corrugated cardboard or corrugated composite. Print version of the corrugated board cable to use white tissue paper, paint foreign general or 85 grams of white cardboard-sided coated paper, offset paper. Finnish forestry company's light and heavy white-coated linerboard surface is corrugated foam cloth,[link widoczny dla zalogowanych], compared with non-coated paper, paper, cloth printing ink Lai higher density of 63%; high gloss 350%, be a good print quality and clear results. However, coated paper printed with ordinary ink, ink often appears uneven, slow drying, it is recommended to use a new generation of ink or with a drying device flexo printing machine and a small area of ​​the first graphic, and then print large graphics, can be black, cyan, magenta, yellow color sequence present, the brand of beer, beverages, food, computers,[link widoczny dla zalogowanych], home appliances and other products have been used in Finland white cattle packing corrugated card. Color to improve the quality of corrugated board, the first major efforts to deal with the printing equipment of technological innovation, high-level configuration of more than 3-color overprint corrugated printing presses, high precision,[link widoczny dla zalogowanych], high degree of automation, the import carton printing presses, computer-controlled production line of carton will increasingly be used. Printing Machinery Co., Ltd. is China's Shaanxi packaging and decoration printing machinery manufacturing industry, the backbone of the enterprise, its leading product YCW series of corrugated board printing slotting machine technology lead at home, mainly for the 3-7 layers of corrugated board or multi-color printing 3 color to complete the indentation, grooving, cutting angle, a deduction hand,[link widoczny dla zalogowanych], playing porosity and other online operations. Commonly used at home and abroad flexographic printing inks, there are three types: ① Flexible water-based ink: mainly used for paper printing; ② Flexible Alcohol Ink: mainly used for plastic printing; ③ flexo ink uv: as general-purpose ink. The printing of corrugated board to use more water-based ink. Ten years ago, the domestic production of water-based ink still in the maleic acid modified rosin resin binder levels, although this water-based ink has good printability and good storage stability,[link widoczny dla zalogowanych], but the printing ink of poor gloss, dry slower and less variety of patience, could easily lead to stretching the paper. Anti-China Ink Chemical Co., Ltd. with good performance of the new acrylic copolymer resin, water-based ink material for the connection, the introduction of high-grade corrugated board printing WBIBF series of water-based flexographic inks. Gangu ink factory, printing ink factory in Tianjin, Shaanxi New Century Institute and the Materials Co., Ltd., Jinan Lu Yang Ink, Tianjin Toyo Ink also has developed a high-quality water-based ink, water-based ink in the process of replacing imports played a positive role . Ink drying rate has been able to reach 200m / min resolution over 150 lines / inch, less than solvent-based gloss ink blot. Water-based ink system of indicators include Zhu viscosity, pH, dryness. Roller is a key component of flexo, flexo machine heart. It is the use of special equipment will be carved into the roller surface shape of a specific network points made, it is the role of the ink evenly and accurately transferred to the printed edition, which is also called anilox roller roller. Metal roller is made of metal molds or electric carving machine in a softer metal roll at a certain number of lines and network points carved shape extrusion and for making a certain hardness, a layer of chrome plated, chrome net roller hole structure is Metal itself is not as good as ceramic wear, use of the near net thickening of the wall began to set out the amount of ink drop, in the same squeegee, the color levels will drop, the printed version of the network is easy to network points deep inside, next to the dip with the excess ink, resulting in blocking version, printed a large ink dots should appear. Due to the characteristics of the metal mold and metal restrictions, chrome roll is difficult to achieve high lines. Usually reached 4OO lines /
