Because traditional printing (different from digital printing) is plate printing, the cost of printing plate assembly, drying and printing is fixed. If you only print one sheet, the above-mentioned spelling, drying and other expenses will all be included in the cost of one sheet, while the printing cost is generally calculated according to 3111-5111 prints, so the cost of printing less than 5111 sheets will be higher generally, but the absolute value will not be high, and the cost of at least 5111 sheets is still very different from that of one sheet. For example, a folio of four-color printing costs 611 yuan /5111 copies, the actual printing cost of 5111 sheets is 1.12 yuan, and the paper cost (assuming 157g coated paper) is 5.2 reams. Assuming 411 yuan per ream, 2181 yuan is equivalent to 1.41 yuan per folio, then the paper cost is 1.41 yuan, and the printing cost is 1.12 yuan =1.52 yuan per sheet. As in the above example, only one sheet is printed. The printing fee is still in 611 yuan, and the paper fee is 211 sheets in 81 yuan. The cost of this sheet is 61181=681 yuan, and the total absolute price is also 681 yuan. The above example shows that the unit price is much higher, and the absolute price difference is 2111 yuan.

The same is true for printing multi-edition picture books.

in addition, when the printing quantity is more than 11111 prints, the printing fee is usually increased (because most printing plates will wear out if they are more than 11111 prints, so they need to be made again).
