Future trademark printing machine exploration

review the previous global trademark printing Exhibition (labelexpobelgium1997) held in Belgium. Among the trademark printing machine products on display, the focus is on the promotion of full rotary and intermittent rotary machines. The full rotary wet offset printing machine recommended by European and American manufacturers has good printing effect, but it has not avoided the loss caused by proofreading, parking, driving and printing, The reason is that alcohol fountain and ink roller can not reconcile the best ink and fountain in a short time; As for the "flexo" flexo printing machine, when printing fine dots, the performance of ink and flexo is not fully developed, which is limited to the production of a product with a required structural component that can reconcile the working quality

in view of the above obstacles in the printing process, the manufacturer has further studied alternative printing technology, and successfully developed a rotary intermittent dry offset trademark printing machine. With the super high point of 300lpi as the call, the vacuum sipping gun is used to ban the traditional paper pressing wheel, so as to avoid dragging or embossing paper when the paper pulling gun rolls. It is a good design for products with protective film. Vacuum 3. Control accuracy: upper limit +2%, lower limit ⑴% the sipping air gun controls the line position of the servo motor with a pulse signal of more than 560000 parts divided into 360 degrees. The paper pulling and color setting are accurate, and there is no need to buy a printing gun with different diameters, which completely avoids the friction of the paper pressing wheel on the printing material and increases the loss. If necessary, the printing range can be expanded to the whole printing area

other functions include synchronous die cutting and bronzing of flat beer. The Chinese standard mainly adopts the tension control of different printing material sizes of plum type samples and Charpy V-notch samples, and the independent exhaust tension of feeding and discharging to maintain the paper balance. The whole printing process is completed at one go. At present, there are more than 20 relevant models in the French market alone, known for printing high-end liquor trademarks, VIP plastic cards and other products

to sum up the experience of the Belgian trademark exhibition, the author believes that the future trademark printing needs are as follows:

trademark products tend to be offset effect and delivered in rolls

take the point change effect as the center, and 175lpi as the basic requirement

the rotary printing machine is designed intermittently, eliminating the plate changing gun, and can be produced at high speed, so as to reduce costs and increase benefits for manufacturers

the printer can process any material, including transparent film materials, metal materials such as aluminum foil, electrostatic materials, films of different thicknesses and thicknesses up to 0.47mm

in the case of high awareness of environmental protection, any printing material should try to avoid PP lamination and replace it with UV varnish or local varnish, so that it needs to be equipped with a surface processor for the glue surface

in the past, when dealing with the general silk screen transparent film, aluminum foil, film printing white ink floor, it was necessary to reduce the speed of the printing car. When the rotary silk screen printing combined with the intermittent rotary printing unit and combined the two printing forms synchronously, it can still maintain high-speed operation and completely eliminate the deceleration barrier. These technologies are now very popular in Europe, while only Japan was first applied in Asia, and Hong Kong and other Southeast Asian countries have not introduced them

the intermittent rotary trademark printer is printed by the full computer-controlled color group without replacing the printing gun. The rotary silk screen printing, flat beer, glue mounting, bronzing, polishing and other processes are completed at one go. These forms are mainly led by national scientific research institutions to carry out relevant research projects. The research-based design is in line with economic benefits, which is actually a breakthrough in the rotary trademark printer in the past decade
