â‘ The cutting size should be accurate, the error is less than 2mm; no skew, smooth cut, no knife flowers and knife marks, no broken.
②The allowable error of opening materials is: opening large sheets, illustration materials, scattered sheets, and the error does not exceed 2mm. The error of opening the cover material does not exceed 1mm ± 0.5mm. The error of opening double is 1mm, at most it does not exceed 1.5mm. Open hardcover cardboard error does not exceed 1mm. The gap between the head of the chart and the gap of the foot is larger than that of the foot, and the general ratio is (4: 5) ～ (4: 6). In contrast to European countries, European countries usually design from small to large.
â‘¢ In the design of material opening, the book block binding line should be considered to be consistent with the direction of the paper thread, that is, the paper thread along the up and down direction of the book page. In this way, the problem of erecting the pages when opening the book can be avoided, and the open state of the book can be better maintained.
