Powder spraying is an indispensable tool in offset printing. The printing powder on the market is mainly made of pure plant materials. Commonly used materials are flour, corn flour (corn starch), plant starch, cassava powder, etc. Its main function is to prevent the back of the printed matter from being sticky and dirty during the printing process.

　　粉末喷涂颗粒细腻，与油墨同化性好，喷涂后均匀分散，对提高印刷质量和印刷效率有很大帮助!广泛使用;除彩印外，薄膜、橡胶、尼龙、复合材料均可使用。粉末颗粒为球形;表面光滑;粒度10-25米(目号300-450);粉末颗粒均匀性;流动性、分散性好;与油墨同化，亲脂性特别好。完全有效地均匀涂敷在印刷表面，使印刷质量得到很好的保证。

　　Powder spraying particles are fine, and have good assimilation with ink. After spraying, they are evenly dispersed, which is very helpful to improve printing quality and printing efficiency! It is widely used; except for color printing, film, rubber, nylon and composite materials can be used. The powder particles are spherical; the surface is smooth; the particle size is 10-25m (item 300-450); the uniformity of powder particles; the fluidity and dispersion are good; it is assimilated with ink and has good lipophilicity. Completely and effectively evenly coated on the printing surface to ensure the printing quality.

　　那么，在济南标签印刷中为什么要使用喷剂呢?

　　So why spray is used in Jinan label printing?

　　由于每小时15000的印刷速度，在高速送纸机上令人惊叹，也因为其纸张稳定、准确、平整而感叹，因为印刷样品堆积在纸张平台上没有丝毫粘脏现象。一般的印刷机都配有适当的喷粉装置，以便于在油墨层较厚的情况下进行印刷，利用干燥速度慢的油墨或印刷精细高档产品喷粉，防止印品相互粘接或粘滞。高品质电子喷粉已经成为印刷机器的标准,这不仅提高了标签印刷质量(粉更均匀地分布在印刷产品和粉更合理)的数量,而且还节省了大量的粉,减少了灰尘。电子喷粉装置使用更人性化，喷粉范围和喷粉时间可通过触摸屏根据纸张格式进行调整，进一步保证印刷质量。

　　Because of the printing speed of 15000 per hour, it is amazing on the high-speed paper feeder, and also because of the stability, accuracy and flatness of its paper, because the printing samples are stacked on the paper platform without any sticky dirt. General printing machines are equipped with appropriate powder spraying device to facilitate printing in the case of thick ink layer. Ink with slow drying speed or fine and high-grade printing products are used for powder spraying to prevent printing products from sticking or sticking to each other. High quality electronic powder spraying has become the standard of high-end printing machine, which not only improves the quantity of label printing quality (powder is more evenly distributed in printing products and powder is more reasonable), but also saves a lot of powder and reduces dust. The electronic powder spraying device is more user-friendly. The powder spraying range and time can be adjusted according to the paper format through the touch screen to further ensure the printing quality.

　　有时运营商为了减少印刷粘脏的问题,是用来增加粉喷雾方法,这将影响到贴纸标签印刷光泽,污染工作环境,而且还增加了纸机器零件脏,造成严重磨损的印刷和机器将产生负面影响。

　　Sometimes operators in order to reduce the sticky problem of printing, is used to increase the powder spray method, which will affect the gloss of stickers, pollute the working environment, and also increase the dirty parts of paper machines, resulting in serious wear and tear of printing and machine will have a negative impact.

　　喷粉控制原理是在印刷的有效部位，使上下印刷刚好不粘接，那么喷粉量就是更好的喷粉量，主要原因是印刷表面油墨不完全干燥。如果墨水干了，再撒也没有用。印刷师傅在检测印刷时，检查粉末的数量是一项必不可少的工作，这部分工作大多采用目视检查的方法来检查，当发现粉末喷涂不均匀或细小时，要及时进行调整。如果使用不当或其他原因，喷粉装置有时会出现粉块甚块故障。良好的日常维护和正确的使用可以避免或减少喷粉机的堵塞。

　　The principle of powder spraying control is to make the upper and lower printing just not stick to each other in the effective part of printing, so the powder spraying amount is the best powder spraying amount, the main reason is that the printing surface ink is not completely dry. If the ink is dry, it's useless to sprinkle it again. When the printer is testing the printing, it is an essential work to check the quantity of powder. Most of this work is checked by visual inspection. When it is found that the powder is not evenly or finely sprayed, it should be adjusted in time. In case of improper use or other reasons, the powder spraying device may sometimes have powder block or even block fault. Good routine maintenance and correct use can avoid or reduce the blockage of the duster.
