Flexo pre-start preparations for a lot of preparatory work can not do as long as there is a place, it will affect to some extent the quality of printed products. "Details determine success or failure" is off the best interpretation of pre-press work on to improve the quality of printed products has an important role. Print Network HC Years of Flexible Print Practice tells us that attention to detail is very important to pre-press preparation. If you do not place pre-press work, careless, hasty, then it will continue to have minor problems, major problems an embarrassing situation, not only a waste of raw materials, reducing the rate of quality products, the products affected quality, causing serious economic losses, but also may delay the delivery time, reducing the company's credibility. So I believe that optimization of human resources, carefully well before the start of each flexo preparatory work is essential to our work. Soft start preparations before the concrete has the following main points: 1, inspection and maintenance of equipment Equipment is the basis of quality products, careful maintenance and maintenance machinery and equipment is necessary. First, the surface of the machine, into the paper, static and dust some careful cleaning, scrubbing machines all over paper roll, reducing printing production with dirty dirty and sticky situation. Then, the various oiling machine gear and lubricating the mouth to reduce the wear and tear. Also check the drive chain, have loose joints, to master the working state. 2, pre-press process control requirements 1. Familiar with the standard proofs, including proofs of the color condition, the main features of graphic and main technical requirements. 2. Audit printing color sequence and, if wrong to suggest modifications. In general, small ink lines text, small graphics four-color, printed on the front, its easy to dry, low temperature oven, paper distortion, overlay relatively stable; large field, gold ink, silver ink and ink set large graphic on the back of the printing. 3. To understand the main performance characteristics of printing materials, in particular, to master the use of inks, solvents, the main performance. 3, preparation of the inspection and pasting Used version of the roll, should use the same factory produced version of the same batch roller. Check whether the smooth roller bearing rotation, abnormal change in time. Check the gear is clean, and timely cleaning with kerosene, finished grease. Remove the reel shaft material, check whether the damage. Disk clean-up ink, the ink fountain, ink wash pumps, hoses and roller. Clean plate cylinder and Anilox roller . Out before pasting the new plates, using alcohol to one side, wipe clean the residue, and then cut version. Roller according to the number of teeth cut out the appropriate size plate. If cut slightly bigger size, then paste version of good, the plate will have redundant interfaces, and some colleagues would bother to roll directly on the version cut with a blade, it would not scratch the print edition version roll for a long time that the Indian version of Roller will appear above the multiple injuries. If cut slightly smaller size, then paste interfaces well plate gap larger version sealing tape can not be neatly glued to the top, will blister, often wipe print version, solvents will penetrate, resulting in version of the interface of plate sealing tape tilt, the surface of printed unnecessary smudges. CD version so the best plan to use a sharp blade to open, neat, not messy. Dull Knife CD version, plate cutting edge will be a lot better after the glitch will affect the product's overlay. Pasting tape should be affixed flat to live version of roller surface, can not have bubbles. Pasting careful to aim his camera, to ensure horizontal flat plates vertical line overlay. Each version should repeatedly check, check and correct version before they can seal, sealing tape version I use the blade on the back side or flute edges smooth tool to flatten closely aligns. 4, matching the pressure roller and adjust According to process a single matching the corresponding roller. When selected, the same number of lines crossing a roller may be a good use of time with the length of the surface wear is not the same situation, and some even wound, must be well aware of the use of each roller, which the specific use a graphic according to product characteristics, to avoid the blind, will also operate handy.
