The main printing process parameters and Countermeasures unhealthy - printing - screen printing indu

First, the choice of equipment The main process parameters Substrates, are generally not large, and often select a small manual or electric Printing machine To apply. Electric pad printer here for a brief introduction: Printing machine electric main components are: Rubber head , Oil pan, scraper parts group, variable speed, switch the "Run / Manual", fixtures and other lifts. Since it does not need the traditional pump gas source, and uses 220v civilian Power supply Mechanical drive system. Electronic continuously variable transmission functions, making operation of the venue operator proficiency, printing products greatly simplified under the machine speed, the advantages were also prominent: stability, precision control, low cost, small size, ease of use, quality reliable. 2, plastic head model The main process parameters plastic head should have good ink and inking, good elasticity and fatigue resistance, good resistance Solvent Properties. Printing on plastic products according to head size, shape, hardness, color comparison chart provided by the supplier or in-kind models to choose, after that the actual use of the situation and life shaping a model specification. pad printing materials should contact deformation with smaller diameter than the first word printed on the case about 3mm, plates fine lines and more, choose a relatively soft plastic head and more. plastic head to be placed on the 5? 25 dry and ventilated warehouse storage. newly purchased plastic surface layer of release agent first before use with a clean cloth dipped in alcohol or wash cloth version of agents. plastic extrusion head and the depth of printing materials shall not exceed the plastic head height 1 / 3, otherwise the plastic head easy to damage, fuzzy pattern deformation. Bad behavior and treatment pad surface, if rough, pine thinning, oil, formation of such phenomena are not only cleaning or replacement. plastic head right shape, sizes, size small so choose a certain angle symmetric plastic head, or for different forms of plastic head, in particular, should be based on the desired results, cone-shaped plastic head with a garden can be seen India network, with a flat plastic head and India is not visible locations; with a large plastic head; all be consistent with the hardness of plastic heads. installation location too far, too much friction force is too small and so on, adjust the center position, adjust the intensity of use rubber head with sharp points and hard points, plastic head, suitable for the surface is too soft and too thick. Three ink types The main process parameters Printing ink Should consider its features: transfer properties, drying rate, color dense cover, such as thin focus. This proposed generic ink, the type of ink and Additive Logo printing characters can in plastics, rubber, glass, nylon and other materials on canvas. Features the full cost of suitable adhesion line, color vision, less inventory, more choices. But Pe / pp, baking ceramics, do not apply. Should be based on the text pattern, size and printing products, select the appropriate interpretation of thin adaptive agent, generally used in the Standard, type. Bad behavior and treatment Ink under the following conditions: amount of ink absorption in the small plastic head, the release of small, obscure enough, deformation patterns, stains, leveling uneven, assumed the nature of good, stable color, dot met, broken fine lines, substrate surface eye of a needle or filament, or bright enough ink drop off. Gotta deal of thought is: the thickness of ink, solvent speed, Yen and the substrate with ink, plastic steel version of the first adjustment and other measures. The key solution is generally only fall on two opposite parts, the do not need all the action. Highlights the essence of all in 2009, "China Industry News Daquan?
