First of all, in terms of software:
1, file
2. Create a new document
3. Page size (user-defined, marked with 1 in the figure, I am used to only the finished product size, take generous 16 as an example, and use 3mm bleeding line? By the way, the bleeding line setting suggestion here: binding can be divided into lock binding and wireless binding. When binding, wireless binding needs to leave a back position for washing, and lock binding does not need it. That is to say, if the book is bound by sewing, without internal bleeding, and only by binding, bottom, outside and wireless, then there must be bleeding on the top, bottom, inside and outside. Picture label 3.
4. Margins and columns (the setting of the version center starts here, and the pictures are marked with 4)
5, margin (the distance left by the finished book, the setting here is the distance left by the finished product size, marked with 5 in the figure)
6. Number of columns (change the number of columns with 1 column pass without changing)
7. The size below the column is the size of the center you built (that is, the finished product size minus the upper and lower margins, 285-20-20=245, 2 10-20 = 170, and the picture label is 6).
Secondly, according to personal experience, the setting of the page center is also related to the actual needs of customers, such as the size of the font size required by customers, the number of words in a row, the number of lines to be placed on a page, and the row spacing, plus the size of the page number and the aesthetic degree of the page, it is more accurate.
Must the center of the left and right plates be close to the outside?
Binding has nothing to do with the center of the version, but only with the page size and paper size, so when creating a new document in front, add blood lines.
Is there any bleeding at the binding?
Same as above, if the thread is bound with glue, the internal bleeding will be 0mm, up and down 3 mm; Wireless glue, 3mm above and below, inside and outside.
From my personal experience, I hope I can do my bit.
