    网版的制作过程是怎样的?
    2018-12-25 10:07:41

    绷网:选配所需丝网布,按张力、视点等要求绷网,用拉网机固定在铝网框上,按规则的张力刷粘网胶绷制丝网版,丝网布有涤纶、尼龙等原料。
    Wire-stretching: Wire-stretching cloth is selected and matched. Wire-stretching is required according to tension and viewpoint. Wire-stretching machine is fixed on the aluminium mesh frame. Wire-stretching is brushed and glued according to regular tension to make screen-stretching plate. Wire-stretching cloth has polyester, nylon and other raw materials.
    洗版:专用稀释剂、开孔剂等悄悄擦拭网布,铲除杂物,避免堵网。
    Washing plate: special diluent, hole opener, etc. quietly wipe the mesh cloth to remove impurities and avoid blocking.
    涂布:把绷好的网版用手涂或涂布机上感光胶。感光胶分单液型和双液型(重氮系),双液型感光乳剂涂之前需敏化,重氮光敏剂彻底溶解后与乳剂混合均匀、脱泡后才可使用。单液型感光胶,悄悄拌和均匀之后即可使用。涂布时应避免刮斗带进气泡,枯燥温度在30~40℃。膜厚依印刷物的要求而定,可通过涂布工程的次数控制膜厚。
    Coating: Use hand-coating or photosensitive glue on the coating machine to coat the tensioned screen plate. Photosensitive adhesives are divided into single-liquid type and double-liquid type (diazo system). Double-liquid type photosensitive emulsions need to be sensitized before coating. Diazo photosensitizers can be used only after they are dissolved thoroughly and mixed evenly with the emulsion and defoamed. Single liquid type photosensitive adhesive can be used after mixing quietly and evenly. When coating, air bubbles should be avoided in the scraper, and the drying temperature should be between 30 and 40 degrees Celsius. Film thickness depends on the requirements of printed matter, and can be controlled by the number of coating projects.
    枯燥:在40℃以下温风枯燥。
    Boredom: The temperature is below 40 degrees Celsius.
    曝光:将菲林底片张贴在网版正面,在晒版机(紫外线)曝光,紫外线照耀过的部分失掉水溶性,根据感光胶,曝光时刻不同,确定最佳爆光时刻后曝光。
    Exposure: Film negative is posted on the front of the screen. When exposed to ultraviolet radiation, the water solubility of the part irradiated by ultraviolet radiation is lost. According to the photosensitive, the exposure time is different, the best exposure time is determined.
    注意事项:
    Matters needing attention:
    曝光缺乏会下降网版的耐印次数,曝光过量会影响图画的明晰度。
    Lack of exposure will reduce the number of times screen printability, overexposure will affect the clarity of the picture.
    显影:用清水将曝光后的网版双面浸透或放置于水槽中1~2分钟,取出后用高压水枪水雾状冲刷网版(遭到紫外线照耀的部分有感光胶硬化在丝网上,没有遭到紫外线照耀的部分溶解于水中),直至所有图纹显影明晰停止,除掉多余的水份用加压气枪、鸡皮布等去除。

    Developing: Immerse the exposed screen in clear water or place it in the sink for 1-2 minutes, then wash the screen with water mist of high-pressure water gun (the part exposed to ultraviolet radiation is hardened on the silk screen, the part not exposed to ultraviolet radiation is dissolved in water), until the development of all patterns stops clearly and the excess water is removed by pressure air gun, chicken skin cloth, etc. Except.
    枯燥:在30~40℃条件下枯燥。
    Boredom: Boredom at 30-40 C.
    检版:枯燥检查。批改网版,针孔处加以修补。
    Inspection: boring inspection. Correct the screen version and repair the pinhole.
    二次曝光:补边剂枯燥之后,从刮斗面开始进行二次曝光,二次曝光的时刻与主曝光时刻相同。二次曝光可提高网版的耐印性
    Second exposure: After the edge-mending agent is dry, the second exposure starts from the scraper surface, and the second exposure time is the same as the main exposure time. Secondary exposure can improve the printability of screen plate
    将感光胶流到网布上, 向上用力刮去,直刮到网布上方停止,使其均匀地涂布在网布上,然后用吹风机热风吹干。
    The photosensitive glue is flowed onto the mesh cloth, scraped upward and stopped over the mesh cloth, so that it can be evenly coated on the mesh cloth, and then dried by hot air with a blower.
    网版吹干后要当即进行感光晒版, 避免悉数感光,将网版平放在灯光下面,再将阳片菲林 感光胶膜向上 放在网板上,再用玻璃盖上,用两个铁夹在左右两边压紧, 灯光至网版的适宜距离是20cm-30cm. 感光时刻约八至十分钟。
    The screen plate should be sensitized immediately after drying, so as to avoid all sensitization. Place the screen plate flat under the lamp, then put the positive film film Film photosensitive film upward on the screen board, then use the glass cover, and press the left and right sides with two iron clips. The suitable distance between the lamp and the screen plate is 20 cm-30 cm. The sensitization time is about 8 to 10 minutes.
    感光后的丝网印刷网版, 用水冲刷或用海棉轻擦,冲水的水压要适中,不可太强,不要把网布冲破。
    Photosensitive screen printing plate, washed with water or wiped with sponge, flushing water pressure should be moderate, not too strong, do not break the screen cloth.
    丝网印刷网版用水冲出图案后,再用干布盖在网版上下两方将水份吸干。让网版自然干或用吹风机吹干。 这样便完结制版工序。
    After the screen printing screen plate is washed out with water, it is then covered with dry cloth on both sides of the screen to absorb the water. Let the screen dry naturally or with a hair dryer. This completes the plate-making process.
