Control of Fineness of Printed Products in Flexo Printing Process
First, the ink adjustment in the printing process directly affects the fineness of the flexographic product
Fine prints usually meet the following quality requirements:
1) Solid and delicate on the ground, with neat surroundings and no ghosting.
2) Part of the network cable satisfies: clear, small deformation, and distinct layers.
3) Fine lines and small texts require clear lines, exquisite text, and no paste.
4) Multi-color printing requires accurate overprinting, no leaks, and no overlapping frames.
So, under the premise that the printing pressure has been adjusted in place, only by adjusting the ink properties to maintain a stable viscosity and good printability, the printed matter can meet the above four requirements.
such as:
1) The ink viscosity of the general field product is 45' to 60' (paint # 4 cup), and the ink leveling and hiding power of the viscosity range are both. Ink coverage is good, solid level; ink leveling is good, the field is delicate and shiny. Otherwise, the viscosity of the ink is too large, the ink transfer ability is poor, and the printing on the ground is not true; the viscosity is too small and there are water marks on the ground.
2) The viscosity of the ink used in the cable products is 30'-40'(paint #4 cup), the ink transfer performance of the viscosity range is good, and the reproduction performance of the dot is strong. The printed product dot is clear and the deformation is not easy. Paste, dirty version.
3) Multi-color printing products should be designed to minimize the trapping parameters under the premise of satisfying overprinting, and the printing color sequence should be reasonably arranged to ensure that the ink color of the latter color can cover the trapping of the previous color. live.
Second, the setting of the printing process has a crucial influence on the fineness of the product during the printing process.
Printing process settings: such as the trapping parameter settings, the printing sequence before and after the arrangement, there is pressure convex, hot foil can not be connected to the post-process set the mark.
The company once had a product that was darkly overprinted on the ground twice, with many small anti-white characters on it. We design according to the normal trapping parameters, and the results are not clear and imperfect. Later, in practice, we worked out the rules, set them according to “anti-trappingâ€, and arranged printing sequences suitable for the trapping parameters so that the anti-white characters would be printed beautifully, and it would be almost impossible to see the two-color overprint. effect.
Compared with offset printing and gravure printing, the flexographic printing press has poor overlay accuracy. If the products printed by the printing factory must be processed through subsequent processes such as bronzing and embossing, and they cannot be completed online with the flexo press at the moment, then the simple and easy-to-read mark on the plates is to ensure that the subsequent processes are gilded. The exact premise of die-cutting. This is a very small job in the printing process setting, but it is the key to ensure the exquisiteness of the product after the packaging is formed, and whether the product printing is suitable and perfect after the packaging is used is an important aspect reflecting the fineness of the product.
In short, the improvement of the fineness of flexographic products, in addition to being directly related to the printing equipment and the printing plate production, has a direct bearing on the selection of the substrates, the ink adjustment, the printing process, and the printing operation level during the printing process. Closer relationship. It can be said: "Who owns these software technology talents, who will control the fineness of the flexographic products in the printing process, and who will truly have high-quality flexographic quality?"
Lanyard
1.What is lanyard:
A lanyard is a cord or strap that is worn around the neck to hold an identification badge, whistle, keys or other small object. You can see lanyards in use everywhere by businesses, schools, hospitals, at special events, conventions, reunions, and in many recreationall activities.
2.Lanyard Category:
Based on different material used for lanyard production, here are five kinds of Zipper: Heat Transfer Lanyard , Silk-Screen Lanyard , Silicone Lanyard, Zipper Lanyard and Jacquard Lanyard.
2.1. Heat Transfer Lanyard
Sublimation Lanyard is designed in the pattern, production copperplate, electric carving through the mechanical sub-color pattern engraved on copperplate. Copperplate printing machine and then get on the pattern printed on the PET film, and then through the mechanical heat transfer lanyard pattern is transferred to the product.
Sublimation lanyard content can be product brands, publicity posters, slogans, may also be sporting events, concerts, commercial activities, the name and other gatherings LOGO. Nylon, cotton, bamboo fiber can not withstand high temperatures, and high cost to go through a special process to heat transfer lanyard.Such as custom printed lanyard,double hook lanyard.
2.2. Silk-Screen Lanyard
Silk webbing lanyard is the production process LOGO traditional common expression, LOGO is printing ink by screen printing on the surface of the webbing. Printing out of LOGO texture clear, strong sense of three-dimensional, high definition, good adhesion.
Generally can be divided into screen printing lanyard phone lanyard, U disk lanyard, MP3 lanyard, working lanyard, lanyard exhibition, documents cards sling, brand badge lanyard, badge lanyard, lanyard visit visitors Wait. Product brands, publicity posters, slogans, may also be sporting events, concerts, commercial activities, the name and other gatherings LOGO.
2.3. Silicone Lanyard
Silica gel is silica gel mSiO2 · nH2O made of a suitable dehydrating porous materials of different particle sizes. Has an open porous structure, specific surface area (surface area per unit mass) is large, can absorb many substances, it is a good desiccant, adsorbent and catalyst supports.
Silica gel lanyard using silica gel as a material made of, but not limited to mobile phone ornaments, can be widely used in MP3, MP4, digital cameras, small flashlights and other products of the match.
2.4. Zipper Lanyard
Zipper lanyard and zipper is shaped the same,It is the perfect companion for the mobile phone, brand certificate, key ring. Beautiful and practical zipper manufacturing plating with laser engraving and other advanced technology refined elegance applicable Peigua digital cameras MP3 U disk, PU rope, PVC rope, zipper cell phone rope, rope, harnesses, hand Wan belt.In addition to metal beads, other materials can be printed corporate LOGO logo, and in different parts and assembly methods, play publicity, promotional purposes. According to customer needs, design and manufacture many styles, diverse fashion lanyard!
2.5. Jacquard Lanyard
Jacquard Ribbon Ribbon is a high-grade varieties.
Jacquard Ribbon generally used for high profile clothing materials or decoration materials (such as curtains, sand release material). Jacquard manufacturing process complicated. Warp and weft interwoven ups and downs, to form different patterns, convex, more weave flowers, birds, fish, insects, animals and other beautiful patterns.
Jacquard Ribbon soft, delicate, unique and smooth texture, good gloss, good drape and breathability, color fastness (yarn dyeing). Weft jacquard pattern amplitude with large and beautiful, color structured three-dimensional sense, and by the Jacquard pattern is relatively simple, relatively simple.
