Advantages of a self-made surface presses
Surface printing device itself is not a high-tech products, neither complicated nor profound, slightly understand some mechanical brake principle, and has extensive experience in screen printing can make the best of per capita, hands homemade. Homemade surface printing device because there is no electrical devices, thus avoiding the use of electrical and pneumatic circuit failure caused by maintenance troubles; Furthermore, light homemade surface printing unit weight, low cost, simple and flexible, one can. Not only changed the traditional surface printing machine bulky, expensive, and features a single, rigid sluggish and monotonous, but also to meet the modern surface substrate specificity and diversity.
Second, what is the surface printing
As the name implies, all in order to achieve landscaping, decoration, embellishment purpose, surface structure or shape is not flat, but a variety of materials bend, arc, concave, convex shaped objects, such as commonly used in our daily lives, a common cups, glasses, tea cylinders, ashtray, all kinds of bottles, tubes and chemical, medical test tube, smoked glass, measuring and other screen printing its specific or non-specific position of the surface carried out, can be called "surface printing."
Third, the importance of the choice of blade
When the surface of choice is critical squeegee (Note: sometimes ignored by many screen printers), scraper (also called squeegee), specifically an ink "forming screen" on squeeze Pressure to hand the substrates with or machine tools, usually by the thickness of 8 ~ 10mm, the hardness of 60 to 80 degrees Shore (Shore A) of the polyurethane strip and install wooden or aluminum handle constitution. Experienced screen printers all know, when the surface printing using squeegee must have "two high four tolerance" conditions, that is, high flexibility, high hardness; chemical resistance, solvent resistance, acid and alkali, abrasion . Especially when trapping fine curved objects, but also to pay attention to the choice of the blade, the only way to achieve a multiplier effect, proved too.
Fourth, the main principles of surface printing device
We cylindrical object to be explained, mostly cylindrical surface of substrates is the use of the outside diameter of the bearing type rolling four-point support to complete the printing, homemade surface printing is no exception, only mechanical means more than the other two sets of flexographic printing. When printing different from when extraordinary or taper larger objects, as well as in case of "with the" vessels, plus attached a special "mini auxiliary runner" and explore rod "ID telescoping wheel."
① special "mini auxiliary wheel" is for a diameter of 0.8 ~ 2cm objects (e.g. process chopsticks, pen housing, a brush pen, glass tubes, etc.) printing;
