When checking the blue paper, in addition to judging whether it is possible to make a folding hand or a middle position based on the above contents, the following items should also be checked.
(1) Check the order of the blue paper, the positive and negative, upper and lower relationship of the graphic
It is necessary to check the order of the blue paper according to the way the product is used. The positive and negative, vertical relationship of the graphic is correct, and the side that needs to be bound and the binding process are clearly marked on the blue paper.
(2) Do a good job when marking multiple versions
If the same product is divided into multiple versions, each version must have a blue paper, and each version of the blue paper must be marked differently to indicate the difference, generally should be clearly marked on the product home page. When checking blue paper, check it carefully against the original document or design draft or ink draft.
(3) Guarantee the integrity of blue paper
The blue paper must be complete. If the calendar or desk calendar contains special paper or non- printed base paper, you need to put white paper on the blue paper and mark it clearly; the desk calendar bracket should be glued to the text, and the cover and back cover dimensions should be marked.
