Under normal circumstances, everyone's request for corrugated board quality is: the board should be flat, the size is accurate, and there should be no spots on the surface. If the appearance of the corrugated board has spots, it will affect the printing color, and the printing color at the spots will form the color difference. And some electronic customers are very strict about the appearance of paper, and it is generally not allowed to have spots. So why does the appearance of paper show spots?

　　現象解讀：原紙外表呈現斑點，普通都是由于原紙的問題，由于原紙在消費過程中，里面殘渣了熟料成分的物質，經過面紙加熱過程起到化學作業，細小的塑料顆粒消融后產生大小不一的黑色斑點，這種狀況呈現較多的是以再生紙為紙基的掛面紙。

　　Phenomenon interpretation: the appearance of the base paper shows spots, which are generally due to the problems of the base paper. During the consumption process of the base paper, there are residues of clinker ingredients in the base paper. After the heating process of the surface paper, the chemical operation is started. After the ablation of small plastic particles, black spots of different sizes are produced. This situation presents more of the surface paper based on recycled paper.

　　處理辦法：將面紙在運用前取樣緊貼預熱缸，加熱兩分鐘后取下觀看紙樣，此時點呈現即可運用，假如有的話就要改換原紙。另外在選用原紙時，不要貪圖廉價，應選具有良好信譽的原紙。

　　Treatment method: before using, sample the face paper closely to the preheating cylinder, heat it for two minutes, then take down and watch the paper sample. At this time, it can be used without spots. If there is any, change the base paper. In addition, when choosing base paper, don't be greedy for low price. Choose brand base paper with good reputation.
