In the process of printing and packaging, sometimes there will be stripes on the print or different colors of the online commercial. Online commercial advertisements cannot be printed with ink. Poor printing on deinking roll is caused by gelation caused by swelling of pigment filler in ink. The gelation of ink is due to its high yield value, the ink is too sticky and becomes cheese-like. From the perspective of application, too much pigment and filler in the ink, so that the ink in the storage process into the ink gel or water, resulting in local flocculation.

　　人們采取了各種措施來(lái)防止膨脹和凝膠化，包括不斷攪拌墨斗中的墨水，在墨斗廣告宣傳單中安裝攪拌器，制作廣告宣傳單或在墨斗上放置鐵棒來(lái)制作墨水。 向墨斗輥推動(dòng)以保持墨水流動(dòng)。 操作中使用中、高粘度清漆或稀釋劑調(diào)整油墨（必須配合調(diào)整使用，否則油墨會(huì)繼續(xù)膨脹或凝膠）。 有的廠家用流動(dòng)性好、耐水性強(qiáng)的油墨代替油墨印刷。

　　Various measures were taken to prevent swelling and gelation, including constantly stirring the ink in the ink bucket, installing a blender in the ink bucket advertising flyers, making advertising flyers or placing iron bars on the ink bucket to make ink. Push the ink bucket roller to keep the ink flowing. Use medium or high viscosity varnish or thinner to adjust the ink (must be used together with adjustment, otherwise the ink will continue to expand or gel). Some manufacturers with good liquidity, water resistance ink instead of ink printing.

　　印刷包裝油墨凝膠化和膨脹的原因：印刷包裝油墨的凝膠化問(wèn)題在早期油性（氧化干燥和滲透干燥）和水性油墨單張中偶爾會(huì)遇到。 傳單設(shè)計(jì)制作造成凝膠化的原因是設(shè)計(jì)制作很復(fù)雜，包括油墨制造的工藝流程，如先加催干劑和后加催干劑，以及油墨的種類和質(zhì)量等成分。 當(dāng)油墨成分發(fā)生變化時(shí)，也會(huì)出現(xiàn)各種問(wèn)題。

　　Reasons for printing and packaging ink gelation and expansion: printing and packaging ink gelation problems in the early oil (oxidative drying and osmotic drying) and water-based ink sheet occasionally encountered. Flyer design and production cause gelation is the design and production is very complex, including the printing ink manufacturing process, such as adding drying agent and drying agent, as well as the type and quality of ink. Ingredients. When ink composition changes, there will be a variety of problems.

　　凝膠化的原因是：油墨粘度高。 由于油墨體系中樹(shù)脂的分子量太大，油墨的粘度太高，容易凝膠化； 印刷中有許多固體成分。 固體成分過(guò)多，即使是低粘度的樹(shù)脂粘合劑； 印刷油墨具有高酸度。

　　The reason for gelation is: high ink viscosity. Because the molecular weight of the resin in the ink system is too large, the viscosity of the ink is too high, easy to gel; There are many solid components in printing. Excessive solid composition, even low viscosity resin adhesive; Printing ink with high acidity.
