Many friends believe that the thickness of the back can be wider or tighter, but the appropriate calculation formula will make the album more standard. So how to calculate the size of the back thickness of the custom Trading card sets?

Under normal circumstances, the thickness of the paper can be measured with a micrometer. For example, the thickness of conventional 100g/m2UPM double adhesive paper is 0.113mm, 128g/m2 double copper paper 0.1mm, 128g/m2 sub-powder paper 0.12mm, 157g/m2 double copper paper 0.13mm, 157g/m2 sub-powder paper 0.15mm and so on. Then, when calculating the thickness of the back, it can be divided into the following three situations.

1, printing number <12 printing

Back thickness = paper thickness ×(number of copies /2)× number of printed sheets

For example, a 16-folio 128g/m2 double copper paper book with 10 printed sheets, the back thickness calculation method is:

Back thickness =0.1mm×(16/2)×10 sheet

2. The number of printed sheets is 12 to 30

Back thickness = paper thickness ×(number of copies /2)× number of printed sheets

3. The number of printed sheets is 30 to 40

Back thickness = paper thickness ×(number of copies /2)× number of printed sheets

According to the increase in the number of prints, change the value added to the last item can be.

The actual work is calculated in this way, and the difference is only about 0.5mm each time, we may wish to try it.
