In addition to mastering the above skills to identify the external performance of paper products, we should also pay attention to the internal performance of paper. The internal performance of paper is determined by the production process. Paper is divided into whole wood pulp and straw pulp according to raw materials. The price of whole wood pulp copy paper is slightly higher, but the copy effect and texture are obviously better than the latter, and the paper is less wool, which is beneficial to the work of the copy equipment. In production, acid paper and neutral paper are separated by different processes. The price of neutral paper is slightly higher, but it is not easy to generate static electricity, and it is not easy to jam in copying, which is also harmless to human body. When purchasing copy paper, you should not only pay attention to the whiteness and thickness of the paper, the uniformity of the paper surface, the uniformity of cutting, etc, special attention should also be paid to the influence of the internal performance of paper on the copier and on the human body and copy effect.
