布紋絲印中在生產中應該注意什么?

來源:http://www.seven2000.com   日期:2019-07-17

在日常工作中以上所議論的幾點絲印機處置布紋是應當十分留意的其次,在將制造好的布紋膠片拼大版時,應思索到印刷時套印的請求,各聯之間應當留存一定的曠地閑暇。

In daily work, we should pay more attention to the disposal of texture on screen printers. When we assemble large formats of textured film, we should consider the request of overprinting when printing, and there should be some spare time between each couplet.
,網版的張力應到達請求。 布紋是絲印機用來絲網印刷的一個占比擬高的應用.本文談談絲印機在對布紋停止功課時的一些留意事項要點。反之,則可恰當降低絲網目數來改善手感。后,關于不同加網線數的網點,用專用的測試條測出精確的曝光時間,每次曬版后應做好細致的記載,完成數據化管理,使以后的工作有據可依。另外,涂布感光膠的厚度要適中,防止在一塊網版上呈現膠層厚薄不平均、有氣泡的現象,以免對印刷質量產生較大的影響。
First, the tension of the screen should reach the request. Cloth pattern is an important application of screen printing in screen printing. This paper discusses some points needing attention when screen printing machine stops its work on cloth pattern. On the contrary, the number of meshes can be appropriately reduced to improve the handle. Finally, with regard to the dots with different number of screening lines, the exact exposure time can be measured by special test strips. After each exposure, careful records should be made to complete the data management, so that the future work can be based on. In addition, the thickness of photosensitive glue should be moderate to prevent the uneven thickness of the glue layer and bubbles on a screen plate, so as not to have a greater impact on the printing quality.

關于以點陣圖為主的布紋產品,假如絲網目數與加網線數的搭配不公允,由于絲網本身構造及現有制版系統的限制,很隨便呈現干擾圖文的龜紋現象。在運用膠片預縮時,采用以往“挖字”的辦法改善套印會毀壞圖文的完好性,因此只能運用單聯整體挪動的辦法改善套印。以此為根底,加網線數升高,所選用的絲網目數也要相應增加,以進步精度,減少龜紋。留存的曠地閑暇將為后期的模切工序留有余地。普通來說,300目/英寸的絲網,其張力應控制在20—23N/cm之間。
Regarding the lattice pattern products, if the matching of mesh number and screening line number is unfair, due to the limitation of the structure of the screen itself and the existing plate-making system, the tortoise pattern phenomenon which interferes with the image and text is presented casually. In the process of film pre-shrinking, using the previous "digging" method to improve the overprint will destroy the integrity of the picture and text, so we can only improve the overprint by using the method of single-link moving as a whole. Based on this, as the number of screening lines increases, the number of selected meshes should be increased accordingly to improve accuracy and reduce tortoise lines. The spare time will leave room for the later die-cutting process. Generally speaking, the tension of 300 mesh/inch wire mesh should be controlled between 20-23N/cm.
經過屢次打樣印刷,在300目/英寸的絲網上能夠經過調理曬版角度來克制60線/英寸的網點產生龜紋。由于布紋膠片不同于實填的圖案。假如網版的張力缺乏,在印刷時會呈現印跡拉長、套印不準、色相不穩等一系列的標題標題標題標題。而且,加網線數越高,圖文越精密,產生龜紋的幾率就越高。
After repeated proofing and printing, on 300 mesh/inch silk screen, it can restrain 60 line/inch dots from producing tortoise lines by adjusting the angle of the plate. Because the textured film is different from the filled pattern. If the tension of screen plate is insufficient, a series of Title titles such as elongated impression, imprecise overprint and unstable color will appear in printing. Moreover, the higher the number of screening lines, the more precise the graphics and text, the higher the probability of producing tortoise lines.
