在日常工作中以上所议论的几点丝印机处置布纹是应当十分留意的其次,在将制造好的布纹胶片拼大版时,应思索到印刷时套印的请求,各联之间应当留存一定的旷地闲暇。
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.
,网版的张力应到达请求。 布纹是丝印机用来丝网印刷的一个占比拟高的应用.本文谈谈丝印机在对布纹停止功课时的一些留意事项要点。反之,则可恰当降低丝网目数来改善手感。后,关于不同加网线数的网点,用专用的测试条测出精确的曝光时间,每次晒版后应做好细致的记载,完成数据化管理,使以后的工作有据可依。另外,涂布感光胶的厚度要适中,防止在一块网版上呈现胶层厚薄不平均、有气泡的现象,以免对印刷质量产生较大的影响。
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.
关于以点阵图为主的布纹产品,假如丝网目数与加网线数的搭配不公允,由于丝网本身构造及现有制版系统的限制,很随便呈现干扰图文的龟纹现象。在运用胶片预缩时,采用以往“挖字”的办法改善套印会毁坏图文的完好性,因此只能运用单联整体挪动的办法改善套印。以此为根底,加网线数升高,所选用的丝网目数也要相应增加,以进步精度,减少龟纹。留存的旷地闲暇将为后期的模切工序留有余地。普通来说,300目/英寸的丝网,其张力应控制在20—23N/cm之间。
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.
经过屡次打样印刷,在300目/英寸的丝网上能够经过调理晒版角度来克制60线/英寸的网点产生龟纹。由于布纹胶片不同于实填的图案。假如网版的张力缺乏,在印刷时会呈现印迹拉长、套印不准、色相不稳等一系列的标题标题标题标题。而且,加网线数越高,图文越精密,产生龟纹的几率就越高。
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.
