When using a flexographic water-based ink to print non-absorbent substrates such as films and aluminum foils, first select the appropriate printing ink. Since the past gravure printing uses benzene ink or alcohol ink, the adhesion of the gravure ink is not a problem, and some films can be printed even without prior discharge treatment. However, for water-based inks, the adhesion properties of the ink are critical. In order to avoid losses, it is generally necessary to conduct a large number of tests before the official printing in order to select an ink having better adhesion, and the surface tension value of the water-based ink or the UV ink with respect to the printing material should be maintained at 38 dynes per cm or more. A dyne value test pen can be used to test the surface tension of the substrate. The Dyne test pen is a colored pen with a felt tip, draws a wet mark on the surface of the substrate, and then observes whether the wet mark will present a spherical oil film, how long it takes to form a spherical oil film, and In order to judge the adhesion performance of water-based ink on the printing material, this article will introduce you to the manufacturer of the flexo printing machine. Flexo printing has a long history in our country, but in the process of use, there will still be a lack of use, so when choosing a flexo model, it should be judged according to the actual situation. According to the type of printed matter, the quality of the printing machine selects the model of the flexo printing machine. If a certain kind of printed matter can choose a variety of flexographic printing machines, it should analyze the performance and cost performance of different models, and choose the most flexible. The printer's special features and functional models, even for similar flexo presses, will vary in detail when printing different prints. These factors should be taken into account when selecting a flexo press model. According to the type of printing machine selected flexo printing machine, it can be divided into two types: sheetfed and web. The type of flexo printing machine for sheetfed is generally used for printing products with large variety and small output. The printer model is generally used in the case of large batches and small production varieties. The web flexo press models are divided into three categories: cascading flexo press models, satellite flexo press models, and unit flexo press models. These flexo press models are different and suitable for printing. The materials are also different and should be distinguished. When designing the ink draft, the film should be longitudinally reduced according to the above ratio, and then through the plane exposure plate making, the printed product will meet the size requirements. It should be further explained that the printing length is analyzed and estimated in actual production. The determination of R should consider various factors. For example, when the plate roller gear module is 1/8 inch, the printing length can only be increased or decreased by 3.175 mm steps; other factors also reduce the paper consumption, leaving the sticking plate. Remaining, and the limitations of machining indentation die-cutting tools, etc. Article source address: http:// White Tissue Paper Bulk,Custom Tissue Paper,Bulk Tissue Paper,Bulk Of Tissue Paper DONGGUAN YEE HUP TRADING CO,.LTD , https://www.dgyeehupack.com
