First, the imposition, proofing and imposition proofing developing and printing imposition is very different. Printing imposition must be based on binding manner folding order to fight, and part of the film's crosshairs and moldings are to be cut, so that staff can more easily make-up according to the image on the film edges or lines and colors, etc. figuring out where to align and register. And there is no need to consider imposition proofing hands off the issue, cross lines and moldings on the film will be saved. When the make-up of the film as long as the colored crosshairs and moldings can be aligned. In general, proofing color sequence determines the imposition of the color sequence. Because it can improve work efficiency. When the fight first color film to put a level, you can not tilt the corners with transparent tape glued. The other three color version on this basis align respectively. Registration standards for eye can not see the vertical crosshair film and moldings offset phenomenon. To copy, developed by UGRA control bar control is achieved. UGRA control bar has five functional segments, each with its distinct role. As shown in Figure: Paragraph Ⅰ: used to control the printing of development, the plate can also be evaluated exposure. Qualified for the classification from the third stage began, starting ninth grade Bianbu Qing classification. The first section Ⅱ: m coil is used to control the exposure time. Qualified to clearly distinguish at 12μm starts micron coil. Paragraph Ⅲ: network segment points, 10% dot to 100% of the total of 10 in the field, to check exposure and development, also used as a printing characteristic curve standard measurement. Qualified 2% dots appear, 3% dots are clear. Paragraph Ⅳ: fine lines along different angles, you can check whether the network deformation and ghosting. Chapter Ⅴ segment: Fine outlets segment Positive points from 0.5% to 5% and a negative 95 percent to 99.5 percent, to check whether the narrow dot proofing process. Heavy ion micro technology Heavy Ion porous security logo security printing field is developed on the basis of two high-tech research results, a nuclear heavy ion microporous membrane technology, the other is a heavy ion lithography. Its manufacturing process comprises three steps: Firstly, heavy ion accelerator or a reactor neutron-induced fission fragments of uranium as a "shell" Zhangmutou clothing tag printing, plastic film bombardment, ionizing damage caused by a plastic film surface and the inside, forming a nuclear track Then copy the master security identification pattern transition into film version, a lithographic printing base film forming a mask;; basement membrane and finally by a chemical etching process, the base film produced by the heavy ion microporous composition of the original master the same pattern. Heavy ion microporous identified using non-direct radiation imaging method for manufacturing a clothing tag printing, it is the heavy ion lithography development and application in the field of security. Heavy ion porous hole density identified up to several million per cubic centimeter heavy ion microporous. The pore diameter is small, in the micron or sub-micron range, only one hundredth the diameter of a human hair is about, invisible. But by the light diffraction and refraction of heavy ion microporous, security patterns by a large number of micropores community composition appear white in the visual, it is easy to identify with the naked eye Tangxia clothing tag printing, become a popular commodity to identify the authenticity of the macro-based Long clothing tag printing, and heavy ion porous microstructure and properties you can use an optical microscope. Heavy Ion porous security logo has a "microscopic located close macro displays" characteristics, to achieve the security objectives of the Expert identification and public recognition combination. On the one hand, the heavy ion micro microscopic science has very strict parameters, such as pore density, pore diameter, pore overlapping chances like. These parameters are controlled by irradiation and etching processes, forming a strict code signal, permanently stored in the internal knowledge, to become experts in the identification and legal appraisal of scientific evidence. Long clothing tag printing, clothing tag printing, beyond printing by the Dongguan City, often beyond packaging products factory provided. Dongguan Chang-ping beyond packaging products plant (www.dgcyp.com) strong, credible, in Dongguan, Guangdong paper printing industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead beyond printers and you hand into the brilliant, for a better future!
