1. The number of spellings shall take into account the specifications of the printing machine used (including Max printing format and min printing format), the printing quantity, the price of the printed paper and other factors. Although increasing the number of pages can reduce the amount of color page printing, it will increase the cost of making film, increase the difficulty of debugging ink and register before printing, and increase the loss of paper. When the total number of printing is small, increasing the number of collages is often not in line with economic benefits.

2. If the shape of the packaging products to be printed is not rectangular, then single or multiple packages arranged side-by-side will often cause paper waste. In this case, it is necessary to consider whether two or more products can be put together crosswise. Sometimes, it is necessary to adjust the position of the paper box cover on the paper box to achieve compact arrangement. In order to save paper.

3. In multicolor color page printing, regular line is indispensable. Regular line usually uses cross line and is placed outside the finished size of the page. In the case of tight paper size, cross lines can be changed into t-lines and placed close to the finished product. If the paper size is very tight, or for the convenience of post printing processing, the paper size used for printing is just the size of the finished product. You can also place the regular line in the finished product and it will be stuck inside, folded inside, or place the regular line in the position that will be die cut.
