In screen printing, the precision of reproduction of a replica is closely related to the screen. The number of screen meshes has an important influence on the reproduction of the fine lines of a manuscript. Therefore, when selecting a screen, careful selection must be made. The number of screen meshes must be selected. Corresponding to the printing of fine lines, the selected screen size has the ability to reproduce the fine lines of the original so as to ensure the printing effect.
Screen printing fine lines generally refers to line widths between 0.1-0.2 mm. The finest width of the silkscreen reproduction fine line refers to the value of the width of the screen that can be reproduced by the selected screen in screen printing. This is usually directly related to the width of the mesh and the mesh. When selecting a network, the following formula can be used as a basis for selecting a screen calculation.
The formula for calculating the thinnest line width:
K=2S ten R
K represents the width of the thinnest line,
S represents the screen wire width value,
R indicates the width of the mesh.
Calculation example:
If you use 200 mesh/inch nylon mesh, what is the finest width of the reproduction line?
Check the NM 200-inch wire mesh with a wire diameter (S) of 0.05 mm and a mesh width (R) of 0.077 mm. Substituting the above formula, K=2×50 and 77=177=0.177 mm
The finest width of the NM200 mesh/inch screen reproduction line is 0.177 mm.
The definition of new products from the three angles of enterprise, market and technology. For enterprises, the first production and sales of products are called new products on the market; but it is not the case, only the first occurrence of the product's new products; from a technical point of view, in the product structure, principle, function and form change the product called new product. Marketing of new products including the former three compositions, but pay more attention to the feelings and identity of consumers, it is from a holistic perspective to define the concept of products. Any part of the innovation, all products overall concept of improvement, will give consumers a new feel satisfied and the benefit of relatively new or absolutely new products are called new products.
The new product refers to new products using new technology principle, new design development and production, or in certain aspects of structure, material and technique than the original product is obviously improved, which significantly improves the product performance or the use of functional products. It includes the new products approved by the relevant departments of the government and within the period of validity, and also includes the new products developed by the enterprises themselves without the approval of the relevant departments of the government, within one year from the date of production. The direct contribution of science and technology output to economic growth.
