Why Do Different Batches Of Packaging Boxes Print Differently?

When printing products, we will find that there are always some differences in the color of different batches of products. Sometimes the differences are small, and you need to look carefully to see it. Sometimes the color difference will be obvious. Why does this happen?

1. The difference on the paper. Because sometimes a factory does not necessarily cooperate with only one paper supplier, the paper produced by different manufacturers may be different in terms of paper supply, so different effects may be produced after production and printing.

2. The difference in ink. Different batches of inks from ink suppliers will be slightly different, but the impact will not be great.

3. In printing, ink should be adjusted and added again after using the ink, which will also lead to a little difference in color.

4. Climate temperature problem. If the temperature difference is large, it will also lead to color difference.

5. Everyone may see different colors, so it is normal that there will be color deviation.

Why do different batches of packaging boxes have different printing?

There may be many reasons for color difference, some of which are unavoidable. What we can do is to reduce the color difference and enhance the quality of products. This is why the acceptance standard for finished products in the printing industry stipulates that "orders with printing color difference within 10% of the error of C.M.Y.K values are normal orders".
