　　還有一種則是斜看檢查，有些外觀的紙病，如紙面的有光澤或無光澤條痕、毛布痕、伏輥影痕等，用平看檢查方法不易發現，必須用斜看檢查方能看出。斜看檢查是用兩手把紙張的一邊提高一些或放低一些，從不同的角度斜看紙面，發現紙張外觀質量的缺陷或不足。

　　There is also an oblique inspection, some appearance of paper defects, such as glossy or matte strips, wool marks, roll shadow, etc., with the flat inspection method is not easy to find, must be oblique inspection can be seen.

Oblique inspection of the paper surface from different angles reveals defects or deficiencies in the appearance quality of the paper.
