How to choose the UV glue scrape the best effective width

Usually the stencil the effective width of between 20 mm to 30 mm. Based on the selection of optimal effective width substrates flatness, network map as resolution and other printing parameters such as glue scrape Angle, speed and ink types. On the substrates of flat/smooth printing of images of high resolution power, the effective width is small (less than 20 mm), high hard, using suitable ink for printing. On the substrates of uneven, rough, to increase the effective width (sometimes architectural 30 mm), lower hardness, low hardness and adhesive scraping the adaptation ability is poor, not excessive bending, can also use the middle on both sides of the hard soft three layer or double shave. Usually, the effective width increases, the printing speed and to increase the Angle. The stencil shape refers to the cross section of the stencil. Most of the shape of the stencil is simply blow square, other shapes of adhesive used in specific printing conditions. Hard rubber, for example, scraping the performance is better than soft glue scrape, but the poor adaptability of substrates. Use slanting blowing, printing edge easy deformation (similar to soft glue). There are three kinds of the shape of the stencil printing workers can choose: party (or square edge blowing), various inclined and round shave (horn). Party has a wide applicable scope, can provide the largest printing pressure, printing Angle on effective width. Oblique blow to provide maximum flexibility, reduce printing pressure, printing Angle smaller than set point. Round the adaptability of the worst, with minimal printing pressure, printing Angle can be set freely (often is the smallest Angle). These reasons will influence the amount of ink. Blade is to complete the stencil play a important part of the four major functions. Under the control of sharpness is originally the stencil ink amount of a factor. Sharp blade provides the smallest amount under ink and the fine image. Blunt round blade, ink quantity increase, at the same time will affect the fine degree of color and lines. When printing large and simple design with transparent oil, color and line fine degree of the change is not obvious. And fine lines and four color printing network, with a translucent (UV) and transparent ink, you will soon find the deformation of the blade to compare printing first and the last one, can be determined when the stencil should be polished.
