Silk-screen printing technology share — how to choose silk screen

Silk screen's choice including two aspects: Silk screen's type and color. 1st, I take charge of the most commonly used silk screen am the nylon. This kind of silk screen in the intensity, wear-resisting, bears performance aspects and so on alkali to be very good, moreover the price is cheap, but the nylon fishing gear has the characteristic which the laundering back pull drops, therefore, the tight net, after the process exposes to the sun the version, the water flushing development, the tensity will drop rapidly, will have high and the stable tensity screen becomes originally the relaxation, when will be serious, will turn the superseded edition. Therefore, must guarantee that in the development back pull's stability, raises the quality which Gao Si prints, must choose the polyester fiber net, but the price is expensive, creates the product cost the enhancement. The polyester fiber net is weaves by the polyester fiber, its prominent merit is the stability is good, suits high accuracy silk India. 2nd, silk screen's color has, yellow, the amber brown white, red and so on, what my school is commonly used is domestically produced 200 T, the white silk screens, it suits in the quality not high single-color print, the Jan monochromatic block chromatography. Regarding the halftone print, the specially fine print, the silk screen color becomes very important, it will affect the image the resolving power and the clarity. My school usually uses 350 T the imports or the domestic product has the color silk screen, specially uses the decadent silk screen.

Why can use the decadent silk screen? When because the bundle of rays shines to the decadent object surface, the thioindigo red and the green light are reflected, the bluish violet light is absorbed, stimulates the visual nerve which I take charge to present the yellow; Screen printing when exposes to the sun version to make public, what uses is the ultraviolet optical fiber, the decadent silk screen has the absorption to the ultraviolet optical fiber, such light will not have the diffuse reflection in the silk screen surface to present “the halo” the phenomenon; Therefore, obtains the image clarity is high, will not have the halation; But the white silk screen mass-reflex ultraviolet ray, easy to present “the halo” the phenomenon, reduces the image clarity; In order to enhance the image the resolving power and the clarity, raises quality which Gao Si prints, we should consider the silk screen color the influence, the use decadent silk screen.
