W+D Holds Envelope Printing Quality Seminar

Winkler and Dünebier are the main manufacturers of envelope and envelope manufacturing equipment worldwide. From January to February 2001, the company organized an industry-wide international special report conference “The New Millennium Envelope Flexo Printing Quality Seminar”. . At the request of the participants, two meetings were organized in two different languages. One was English, and the other was German. A total of more than 100 delegates from 13 countries attended the meeting. At the meeting, the topics discussed were very extensive. The current and future market dynamics of flexographic printed envelopes and envelopes, the possibility of high-quality prints, and the technological conditions were analyzed and discussed. Many representatives from well-known manufacturers spoke and introduced their own company's products. These companies include not only envelope printing manufacturers, prepress companies, but also flexographic printing plate manufacturers, ink manufacturers, paper suppliers, and machinery. Manufacturers, etc. In the envelope printing industry, is it better to choose flexo printing or offset printing? This requires a comparison of the cost and quality levels of these two processes. This is a very important and fundamental work, especially in the direct mail market where quality requirements are relatively high and the growth rate is very fast. It is better to do this basic work. At the seminar, delegates had already seen each other and analyzed and discussed the advantages and disadvantages of each of the two processes. At the same time, they also gave detailed explanations and explanations on the parameters and their impact on the quality of printed matter. . The organizer also presented to the delegates a new type of center-imprinting (satellite) printing machine, Maxiflex. The flexibility and high quality of the equipment allow it to meet the various demands of flexo line processing. This CI (center-imprinted) press is ideally suited for Helios 627, 202 and 102 devices, as well as for the larger Helios 341 and 249. The equipment uses a temperature-controlled embossing cylinder; there is a hot air drying system between the color groups; and, after drying, it is cooled by a cooling roller and the printed product is “typed”. The flexibility of this equipment is also relatively strong, and the applicable substrate material can be coated paper or offset paper; replacing the workpiece can be completed in a few minutes; besides, it is suitable for water-based inks and alcohol solvent-based inks. print. In addition, because the ink transfer mechanism of this device (including the plate cylinder, anilox roller, closed scraper system, hose system, and ink pump) is relatively simple, it can be ensured that the ink replacement task can be completed very quickly. The equipment left a very deep impression on the delegates. In particular, the fast “job replacement” function made the delegates greatly admire. In addition, the participants’ reflections on this flexo printing special report meeting were also very good. This prompted W+D to strengthen its confidence and prepare to hold similar events in the future to meet the broader needs of the envelope printing industry in the future.
