The the clarity of of the ② and India version of. In photography, hand waving flags for sale the definition refers to the extent of the change of the image edge density on the film, in the wire plate making is a neat version of the film image edge in the horizontal and vertical directions. It consists of three elements: shoulder sharp, bridges and smoothness.
Shoulder and sharp. Founder extent refers to the version of the film images shoulder, as shown in Figure 2-101, a square shoulder (90 °) imprinted the three-dimensional; b collapsed shoulders, Hand Waving Flags For Sale im the edge of the ink thick, uneven, and im expansion of the phenomenon.
Figure 2-101 membrane shoulder sharpness with the im of relationship
Bridging nature. The bridge refers to the version of the film image edge across the mesh to maintain the original shape of the performance. Figure 2-102 shows the bridge resistance, Hand Waving Flags For Sale the difference between the three cases. Good bridge, good reproduction of the image edge, not be affected; bridge trunk bad image edge across the mesh deformation, the degree of deformation version of film material, the location of production methods and image edge and mesh relations its im jagged.
Figure 2-102 version of the film bridging
Smoothness. Refers to the version of the film surface (in contact with the substrate side) formation level. Smoothness determines the version of the film and the substrate surface when the of the FN, as shown in Figure 2-103, where a formation of the when both sides of the FN, the ink flow does not cross-border, the im smooth; b is the formation of version of the film surface with the wire, the hole while the ups and downs, the ink flow will flow Tightlock part imprinted edge jagged, Hand Waving Flags For Sale and every two wind hole is a jagged, tooth shape and approximate size of the FN in the range.

The ups and downs of the membrane surface roughness tester can measure differential. The big difference, smoothness; difference in the 3 ~ 7μm can get good clarity imprinted in a variety of bearing Ibid.
Resolving power of the ③ printed on version of the. The silk screen version of the resolution refers to can be printed to get the smallest image and interval-foot small, with the printed version of the resolution parameters. Usually printed version of the minimum image, when combined with silk wind, the ink flow by blocking may not be able to complete print, im resolution is not equal to the version of the film's resolution. Visible the silk screen of the resolving power of the version of is not good
2 surface version of the film thickness. Affect the layout of the silk screen version of the surface thickness (Figure 2-104) to the im ink film thickness and clarity, especially on the small image, or even change the outlets tone values and color. When product requirements, ink thickness, coarse lines, then the corresponding version of film should be thicker. Version of the film's production to meet the thickness requirements.
