Stencil An Important Variable In The Production Process And Techniques - Screen, Template - Silk

This paper describes the process of making silk screen templates some of the important

variables as well as maintaining quality and stability of several techniques.

Screen Print Manufacturers and screen printing on quality requirements are completely different, the former always in the pursuit of the production process of standardization and escalating. Successful manufacturers will not allow themselves to lose any opportunity to improve quality, they are from reliable suppliers purchase raw materials, and with the improvement of production, they will be measured on every detail and improved. Once they optimize the production workflow will be recorded and maintained for each production step. Here we look at what are the factors that affect the production of silk screen template and how to regulate these factors.

Environmental conditions Most parts do not live

will request a clean room environment, but all the printing companies will benefit from the daily dust and wet work benefit, because it can help them reduce airborne dust and cotton. Pressroom temperature and relative humidity must be controlled, because they directly affect the exposure time, dimensional stability, the situation is set and ink performance on press.

Stretched version

High quality silk screen template by several important factors, Strictly speaking, these elements have nothing to do with the plate-making process. For example, we must according to the customer on the ink film thickness and the image detail required to select the number of mesh and mesh, but also be reasonable to stretch in the template scaffold.

Template tension will affect its stability from the version of the distance and size, thereby affecting the printed version of the set of potential situations. Mesh manufacturers for their own production to provide the best of each mesh tension parameter, the user need only consult on it. If you stretched too tight or too loose will be some impact to the production, so best to replace the measurement of tension about the purpose net tension (Figure 1).

Figure 1: Wire tension is a very important parameter, so it is best tonometer can be used to control its value.

Darkest point density, density and contour map highlights the most

Screen printing, as most currently do not use the screen-to-plate (CTS-computertoscreen) technology, it is necessary to use the copy version of the artwork. This image must have enough density?? Most dark spot density of the best for the 4.0?? To block the light image region, sufficient resolution (the highlight of a lower density)?? To light through the template material costs between image regions and sharp edge definition.

If the original non-image area of the definition is not enough?? Is translucent and not transparent?? And lower density, then it print out the results and the quality of the template will be inevitably compromised. If the edge is not clear enough, then even with high-quality template material, it is difficult to achieve the desired results. In actual production, we can get the ink density of 2.8-3.5 between the images, but its quality is still a loss. The key issue is the quality of camera template better than the original could not, the quality of the printed product can not be better than the template.
