Reasons for differences in printing packaging boxes from different batches

When printing products, we will find that there are always some differences in the colors of different batches of products. Sometimes the differences are small, and we should carefully check before looking. Sometimes the color difference is obvious. Why is this? Why do different batches of packaging differ?

1. Differences on paper. Due to the fact that sometimes a factory may not only collaborate with one paper supplier, the paper produced by different manufacturers may vary in terms of providing paper, and therefore may have different effects after production and printing.

2. Differences in ink. There may be slight differences in ink suppliers from different batches, but the impact on one side will not be significant.

3.After printing with ink, it is necessary to adjust the ink and add it again, which can also cause color differences.

4. Climate and temperature. If the temperature difference is large, it can also cause color difference.

5. Everyone may see different colors, so it is normal to have color deviations.

Why are there differences in the printing of packaging boxes from different batches?

There may be many factors that cause color difference, some of which are inevitable. What we can do is to reduce the degree of color difference and improve the quality of the product. This is why the acceptance standards for finished products in the printing industry stipulate that orders with a color difference within 10% of each value error of C.M.Y.K are normal orders.
