Selection of paper specifications
First, pay attention before the election
When choosing paper specifications, we should not only pay attention to the size of the paper, but also choose the appropriate quantity. Generally speaking, under the premise of meeting the requirements of printing and use, try to choose a smaller number of papers, which can reduce the cost of publications.
Second, post-election attention
1. After the varieties and specifications of paper are selected, the quality grade of paper should be carefully selected. In other words, we should be familiar with the characteristics and quality of various products of various paper mills and keep abreast of their changes.
2. After the type, specification, manufacturer and quality grade of the selected paper are determined, it should also be noted that in the process of publishing and printing, it is best to print the same book with products produced by the same manufacturer at the same time. Otherwise, because the colors of the same paper produced by different manufacturers at different times are often very different, the printed books will be "sandwiched".
