一、點式白化。主要原因進油墨體系對蠟類的表面活性劑類互溶性差造成的；其二是因為油墨結皮之后在印刷的過程中未被復溶而被轉移到圖文上。
1、 Point whitening. The main reason is the poor mutual solubility of wax surfactants in the ink system; The other is that the ink is transferred to the image and text because it is not re dissolved in the printing process.
處理的方法：應該加入芳烴或酯類真溶劑，促其再度溶解。或者在墨斗里安裝一個攪拌器(如采用塑料管材，在其外部用未印刷的塑料薄膜套上，再將兩頭扎緊放在墨頭里隨機轉動攪勻油墨)，或者在油墨制造的時候增添抗氧劑處理。
Treatment method: aromatic hydrocarbon or ester true solvent should be added to promote its re dissolution. Or install a stirrer in the ink bucket (for example, use plastic pipe, cover it with unprinted plastic film on the outside, and then tie the two ends tightly in the ink head and rotate randomly to mix the ink), or add antioxidant treatment when making the ink.
二、點式白點。主要原因是油墨靜電或者承印物靜電造成的。或者因稀釋溶劑產生的靜電(因不同的溶劑其電阻也不盡相同)造成的。一般在氣溫高或者印刷速度快的時候發生。其次復膜的時候前緊后松或者前松后緊，而靜電的引起常見于濕度大的天氣。
2、 Dot white dot. The main reason is caused by ink static or substrate static. Or because of the electrostatic generated by diluting the solvent (because the resistance of different solvents is not the same). It usually occurs when the temperature is high or the printing speed is fast. Secondly, when laminating before tight after loose or before loose after tight, and electrostatic caused by common in high humidity weather.
處理的方法：可在油墨里適量的加大抗靜電劑(過量則影響復合牢度)，選擇電阻比較小的溶劑稀釋油墨，調整放、收接地導線(一般深度為700～1500mm)處理之。
Treatment method: increase the amount of antistatic agent in the ink (excessive will affect the composite fastness), select the solvent with small resistance to dilute the ink, and adjust the discharge and collection grounding wire (general depth is 700 ~ 1500mm) for treatment.
三、裂紋式白化。主要原因一是油墨轉移性能太差，二是印版圖紋太淺而比較容易使油墨體系中的溶劑揮發太快。
3、 Crack type albinism. One of the main reasons is that the ink transfer performance is too poor, and the other is that the printing plate pattern is too shallow and easy to make the solvent in the ink system volatilize too fast.
一般印跡粗糙導致成膜不良，特別是油墨體系或者墨斗稀釋劑的加入吸入了水分而出現的白化，大多出現在夏季車間濕度太高的環境中。
Generally, rough imprinting leads to poor film formation, especially the whitening caused by the addition of ink system or ink bucket diluent, which mostly occurs in the environment of high humidity in summer workshop.
處理的方法：更換轉移性好的油墨或者更換比較深的印版，其三加入慢干溶劑處理。
Treatment method: change the transfer of good ink or replace a deeper plate, and third, add slow dry solvent treatment.
四、整塊印跡的白化。主要的原因：
4、 Whitening of the whole imprint. The main reasons are as follows
1、在連續印刷時間過長，操作者在發現油墨粘度變粘或者變厚的時候，重復加入某一種單一溶劑，從而打破原有油墨體系中混合溶劑的揮發遞度平衡，造成印刷油墨成膜的時候墨層粗糙、泛白
1. When the continuous printing time is too long and the operator finds that the ink viscosity becomes sticky or thick, he repeatedly adds a single solvent, so as to break the volatility balance of mixed solvents in the original ink system, resulting in rough and white ink layer when the printing ink forms a film
2、操作工既使是加入了混合溶劑，但是過量地加入往往使油墨中合成樹脂的含量相對減少，上述泛白現象一樣也會出現。
2. Even if the operator is adding a mixed solvent, but excessive addition often makes the content of synthetic resin in the ink relatively reduced, the above whitening phenomenon will also appear.
處理的方法：一是添加３％～７％的慢干溶劑，尤其是可以增塑油墨而抵抗水分子的侵入的真溶劑；二是選用含有樹脂的專用稀釋劑；三是在油墨里補加５％～１５％的調墨油，以克服因樹脂含量不足而導致的白化，四是在車間安裝能調控溫、濕度的空調或者用吸濕器之。
The treatment methods are as follows: 1) adding 3% - 7% slow drying solvent, especially the true solvent which can plasticize the ink and resist the invasion of water molecules; Second, select special diluent containing resin; The third is to add 5% - 15% of ink blending oil in the ink to overcome the whitening caused by insufficient resin content. The fourth is to install a central air conditioner that can control the temperature and humidity in the workshop or use a moisture absorber to eliminate it.
