The calculation of offset paper loading is as simple as that!

Beijing Regional Books and Magazines formulated by the State Press and Publication Administration Printing plant paper Placing rate of adjustments (can be found in the 1996 Beijing region printers in this price) is the basis for settlement between the paper and the printing press. The third and fourth tables of the method are the offset printing platform (book version) and the color printing plus rate. The first item of the two tables is that the printing and loading are less than 60 per color, and 60 sheets are counted.

The 60 sheets specified in this annotation are an absolute number. The number of positive papers is calculated by the number of copies of the number of papers used by the printed personnel, and then multiplied by the rate of addition. The formula is the number of books. ×Printing ×addition rate = increase the number of papers. According to this, it is known that only the known conditions on the left side of the equal sign can not immediately and intuitively determine whether the number of papers on the right side of the equal sign is less than 60. If you want to determine, you must perform a trial operation, which increases the workload. It is more troublesome. If it is multi-line printing, it is more troublesome, and it is not easy to reach a consensus between the publisher and the printing house.

In order to solve this problem intuitively, we propose the following simplified method for reference only.

(1) Define the customer order number of a product as the number of books.

(2) The quantity printed by the product on the printing press is defined as the number of impressions. For single-printed products, the number of books and the number of prints are the same, and the number of copies in multiple-printing is a multiple of the number of prints.

(3) Assuming that the printing machine prints a single product, under what conditions is the number of papers to be placed 60?

According to the calculation formula of the number of papers to be fed, the yield (printing number × 1 printed sheet) × the rate of addition and release can be obtained. According to the provisions of Table 3 and Table 4, the rate of addition and release is 0.9%, then there are printing numbers × 0.9% = 60 sheets, the number of prints =60/0.9%=6667.

Therefore, 6667 is the number of prints when the number of additions is exactly 60, and the following conclusions can be drawn accordingly.

When the number of prints is less than or equal to 6667, each color is added and placed at 60 sheets.

When the number of prints is greater than 6667, the print rate can be multiplied directly by the print rate.

(4) In the case of single printing, the number of copies is the number of prints. According to the two conclusions in (3), the method of calculating the number of added and released can be determined. If it is multi-printing, it is also very simple. Simply divide the number of books by the number of joints, compare the number with 6667, and then follow the conclusion in (3) to determine the calculation method.

(5) In the actual calculation, the unit of measurement of "Zhang" of 60 sheets does not necessarily mean an original unsized paper, but the paper size actually used when the printing machine is printed, such as six open and four. Open, three open, split, fully open, etc., the corresponding actual number of papers should be (for a pair of open).

Six open: 60/(6/2)=20 square

Four open: 60/(4/2)=30 square

Three open: 60/(3/2)=40 square

Off: 60/(2/2)=60

Fully open: 60/(1/2)=120 square
