Maofeng seniors, Hong Jianxiong:
First, the case
At three o'clock in the afternoon on Friday, a UV glazing factory received a call from an old customer 25 kilometers away, indicating that there was a paper print on the UV varnish that needed to be used the next weekend. At this moment, if the glazing factory sends a car to pick up the goods, it will be less than five o'clock when driving back in the car array. It will be more than seven o'clock after the glazing, and the cost of the UV is only 22 yuan, and the car runs for half a day. It costs $35, so it’s not worthwhile. Finally, I thought of a way to achieve the best of both worlds. The printing factory, such as the glazing factory, sent the photographic printed materials to the printing factory. After more than 20 minutes of processing, it was loaded back, and the UV glazing fee was completed by the glazing factory for free service.
This case shows the cost of glazing processing. When the average shipping cost of the fare is very close to the cost of UV glazing, if only one paper delivery is lost, if the printing factory sets up its own glazing equipment, it only needs to use hydraulic pallets. Car or motor vehicle handling, the cost is much lower, or online glazing on the printing machine, not only the same bite, but also high-speed production. If it is calculated for 1,000 sheets of 22 dollars, the price of the printer is four colors. High, and only need a lower-priced glazing unit to produce, so sometimes the profit of creating online processing is several times that of color printing, so as long as 40%, 50% of the work is used for online glazing, It has a higher profit margin than the external processing, but if the online glazing business is only 10%, 20%, unless the processing situation is very special, it is difficult to create profits. The so-called special processing may use the glazing unit to perform special value-added processing such as special flexo printing or anti-counterfeiting. At this time, the processing value of one thousand sheets of 50 and 100 dollars is very considerable, and the special UV glue recompresses the interference wave holographic mode. Finally, UV curing is carried out to produce a holographic anti-counterfeiting effect, and the added value is particularly high.
Second, the printing and processing equipment of the flat printing is aligned with the flexo
The glazing unit is the earliest and most widely used additional processing equipment for Zhangye Ping Printing Machine. In addition to water-based glazing, UV oil glazing, it now has a double glazing system, first water-based glazing, and traditional color ink is isolated on water. Under the light layer, UV glazing is used to achieve high brightness, better weatherability and abrasion resistance, which is a popular phenomenon. In addition, from the design surface, the common ink and UV ink are mutually repelled to produce a pattern, and some are water-based partial glazing. In the packaging design, bright light, flat fog light and different ink repellent lines become deep. The color base is very prominent. When the double glazing is used in the first traditional color printing ink, it is easier to print, lower price, and the printing plate is more durable. Although the water glazing is more expensive, it is still more cost-effective than the four-color all-purpose UV ink printing. The optical system was published about ten years ago. In recent years, the design has been used more and the materials are more suitable. Therefore, in addition to the purchase of such five-color and six-color printing presses, double glazing, double-unit hot air curing, and extended paper output holders are added. More and more users. The glazing must be in order to make the printed matter more lustrous or matt, etc., in fact, it is not necessarily the case. Some glazing units use a relatively thin, shallow micro-cavity coating roller Anilox Roller to do 50%~60 of the usual amount of glazing. % thin layer coating, mainly for double-sided printing machines, to prevent the printing on the back side of the first printing surface from sticking or double-shadow printing, etc., and to prevent the paper-receiving table from deteriorating the vacuum suction wheel. In order to avoid the use of dusting and anti-staining, this is another application of the glazing unit, which can increase the abrasion resistance in the finished product processing. Some presses can remove the blanket cleaning unit and replace it with a simple glazing unit for thin-layer water glazing. The glazing unit can also be used for gold and silver ink and pearl ink flexo printing.
In fact, the flexo printing machine does not have the ink key for the printing operation (the printing unit of the flat printing machine is actually a flexographic printing unit), and there is no control factor for the ink balance, not only the operation is simple, but also the color correction plate is easy. And the loss of bad quality is small, and it is easy to print the printed matter that meets the requirements without using a very experienced operator. Therefore, flexo printing can be combined with light, enamel film, hot foil, die-cutting, cold-hot, paper-edge, plus numbering machine, etc., and can be connected with gravure and screen printing units to print different thickness layers. For example, if you are scratching the silver powder layer, if you use flexo printing, you need three printings, and the screen printing can be done once. Plain-printed mechanical numbers, barcodes, and even computer-controlled mechanical numbering machines have appeared on 52cm A3 small presses. Medium-sized machines also have the possibility of processing. In the future, it is possible to use inkjet methods, not only to print numbers and barcodes. Personalized data and messages can be added as inkjet printing can print up to 450 meters per minute, enough to handle the 18,000 A1 offset presses per hour. The foregoing glazing unit is also used for white ink printing which is primed before the foil or film color printing, and can also be used for double-layer whitening on the back side of the UV printing film or the 3D lenticular sheet color printing. The only different printing unit configuration cannot be used. Feel free to change, the former processor can not be used for post processing.
Hot foil processing is still hot in the trademark machine and flexo printing machine, and the high-speed flat printing machine hot foil can be said to be very difficult, so it is now popular to print in the hot foil area with UV adhesive, which can be cured by UV after covering the hot foil. Adhesive, after the hot foil is opened, the printing foil is left on the paper surface, the speed can reach 10,000 or so, the printing plate fee can be low with the PS plate, the low energy consumption can be done without high frequency heating and high efficiency, and the large area is hot. The foil does not have a flat air press and the air is not densely imaged, and it can be used for holographic hot foils with very precise requirements. The cold foil must use two units, one on the adhesive printing unit, one on the foil and then on the UV light. The gloss of the cold perm is slightly worse, the width of the hot foil can be vacant, and the length can not be done like a hot stepping step, but it has to go with the pressure roller, which consumes a little more, and there is no difference to the full foil. Die-cutting work on the Zhangye Ping-printing machine, using the magnetic roller to absorb the steel plate die, or using the formal one-piece yin-yang shearing die to die-cut, in the future for less printing and large-volume processing, the light unit will be reduced as above. The effects of engineering and handling will become popular.
However, the printing machine does die cutting after printing and glazing, how to remove waste paper, paper edge, and prevent such as the hole hole scattering, the damage of precision printing machine parts, blankets, this still has to be solved by the machinery factory Program. Zhang Yeping Printing Machine has almost no possibility to connect the film. If it is a flat printing machine and a flexo printing machine, it has become increasingly mature using online precision scanning control and quality control equipment, such as Manroland's "Eagle Eye" quality control simulation system equipment. And Heidelberg's further dual CCD camera can handle the minimum unit pixel size of 0.25 × 0.25mm, its fineness is very high, and the amount of information generated in the place is relatively large, for the printing machine quality control and response It will be of great help, because the operator does not need to take samples and measure, and can immediately detect the parts with incorrect overprinting or incorrect color to make ink control, ink key reaction compensation, and black spots, white spots and dirty spots. To make a more effective response, unlike before, you can't sense smaller flaws, but only can be perceived in 2mm or more. If you match the double-row paper tray, you can choose to concentrate the defective products on the front paper tray, and the rear paper tray is a good product for better quality control screening. The double-sided machine not only reduces the pile of paper once, but also reduces the space to be dried on the back side. It can also avoid the residual printing powder remaining on the paper surface, paper pile, etc., resulting in poor printing transfer on the attached blanket, and easy Dirty plaque, double-sided machine did not turn the wrong probability. The leaflet machine Feida, which uses a roll paper to cut a single sheet of paper, can freely adjust the front and back dimensions of the paper, and the web paper is cheaper to purchase, and it is easier to feed the paper, and the paper has the same elasticity before and after the sheet printing, and the effect is completely the same. Multi-roll paper cutting method can be compared. Zhang Yeping Printing Machine has different development tentacles in the areas of waterless printing, large printing paper size and ultra-thick corrugated paper printing. UV curing ink is printed on multi-media, food, medicine and anti-counterfeiting printing, and has its special purpose.
Third, offline processing professional advantage
Off-line processing, in terms of enamel glazing, not only the variety of materials, but also the smooth, matte points, the old-fashioned solvent-based 胶 glue changed to UV curing glue, PU vapor curing glue, water-based latex has a variety of changes, The online connection is difficult to play in terms of processing changes and speed, because the printing machine is expensive and the production speed is fast to meet the cost. In other words, it is the most suitable die-cutting method for self-adhesive labeling. It is not necessary to go to the edge of the paper. The plastic sheet has to be die-cut only a small amount, because the die is not cut by a large number of die-cutting. It takes about 10,000 pieces to change new molds, so it is not worth the loss of time. However, the pressure of the die-cutting machine is three or four hundred tons, and its structure is resistant to long-term impact. Therefore, the die-cutting unit of the Zhangye printing machine has only developed from a lightweight. In the folder-gluing machine, only offline is possible, but the flexo still has the opportunity to be in the online paste box, and the flat printing has problems with the paper and it is more difficult to go online. The maximum cover of the lithographic printing machine is still turned on and then turned on. To maintain good quality, there must be more than three or forty loss. This is due to the difference in ink flow and ink balance imbalance, unlike the flexo printing. The amplitude and loss are small. The longer the processing line, the greater the loss of any one of the links will be, and the probability of stopping will become higher. It is not suitable for short-run printing, unless it is suitable for long-term fixed work.
Hon Hai, Taiwan's largest electronics manufacturing group, is scheduled to produce and supply its own packaging materials at its factory in Dongguan. In the past, Hon Hai Company had to pay more than 300 million US dollars worth of packaging outsourcing each year. If the packaging materials can be consistently produced in the factory, the cost of transportation can be reduced by a considerable cost. , create more profits.
