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.

　　粉末噴涂顆粒細膩，與油墨同化性好，噴涂后均勻分散，對提高印刷質量和印刷效率有很大幫助!廣泛使用;除彩印外，薄膜、橡膠、尼龍、復合材料均可使用。粉末顆粒為球形;表面光滑;粒度10-25米(目號300-450);粉末顆粒均勻性;流動性、分散性好;與油墨同化，親脂性特別好。完全有效地均勻涂敷在印刷表面，使印刷質量得到很好的保證。

　　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，在濟南標簽印刷中為什么要使用噴劑呢?

　　So why spray is used in Jinan label printing?

　　由于每小時15000的印刷速度，在高速送紙機上令人驚嘆，也因為其紙張穩定、準確、平整而感嘆，因為印刷樣品堆積在紙張平臺上沒有絲毫粘臟現象。一般的印刷機都配有適當的噴粉裝置，以便于在油墨層較厚的情況下進行印刷，利用干燥速度慢的油墨或印刷精細高檔產品噴粉，防止印品相互粘接或粘滯。高品質電子噴粉已經成為印刷機器的標準,這不僅提高了標簽印刷質量(粉更均勻地分布在印刷產品和粉更合理)的數量,而且還節省了大量的粉,減少了灰塵。電子噴粉裝置使用更人性化，噴粉范圍和噴粉時間可通過觸摸屏根據紙張格式進行調整，進一步保證印刷質量。

　　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.

　　有時運營商為了減少印刷粘臟的問題,是用來增加粉噴霧方法,這將影響到貼紙標簽印刷光澤,污染工作環境,而且還增加了紙機器零件臟,造成嚴重磨損的印刷和機器將產生負面影響。

　　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.

　　噴粉控制原理是在印刷的有效部位，使上下印刷剛好不粘接，那么噴粉量就是更好的噴粉量，主要原因是印刷表面油墨不完全干燥。如果墨水干了，再撒也沒有用。印刷師傅在檢測印刷時，檢查粉末的數量是一項必不可少的工作，這部分工作大多采用目視檢查的方法來檢查，當發現粉末噴涂不均勻或細小時，要及時進行調整。如果使用不當或其他原因，噴粉裝置有時會出現粉塊甚塊故障。良好的日常維護和正確的使用可以避免或減少噴粉機的堵塞。

　　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.
