On the number of grams of paper Some time ago, I gave a picture album to the business club. It's 16p. The cover is 200g and the inner page is 157G coated paper. But when I took back the finished product, I felt that the whole picture album was soft and the inner page was not bright. I want to ask what's the reason for this. Is it related to the number of grams of paper? Is it still used for making the inner page of the picture album?

It's normal that the whole album is soft, because the whole album is only 16p
There are two reasons why the inside page is not bright
1. If the paper manufacturer is not good, the glossiness of the paper will be defective
2. The printing ink is not good and does not emit light after coloring
Normal coated paper is bright and glossy, can only say that your post production is not good
3. The inner page is not bright and has nothing to do with the number of grams of paper. 157G of paper means 157G of picture book per square meter, and 157 is the weight unit
If you want the inside pages to be bright, there are two ways:
A choose high gloss copper paper
B. oil the whole book after printing
