Chuanmei is a brand of Anxing Paper, and there are two main models, namely Chuanmei 2008 and porcelain white.
 
Transmei 2008 has two options: 70g/㎡ and 80g/㎡, which quantitatively affects all the physical and printing properties of the paper, generally the heavier the paper, the thicker, and it is not easy to deform and cause jams when printing and copying, so the latter is better than the former, but the price is also nearly 20% more expensive. The moisture content of the paper is 6.1%~6.4%, which belongs to the middle and upper level within the range of the national standard, and should be placed in a relatively dry place, otherwise it is easy to dry the ink or the phenomenon of paper adhesion.
 
Smoothness means the time required for air to pass through the gap between the paper surface and the glass surface, the longer the time, the closer the contact between the paper and the glass surface, that is, the smoother the paper surface, the smoothness of the paper is 25s, and the national standard is greater than 15s.
 
The dust content of the paper has also reached the level of excellent products. The dust degree reflects the number of impurities on the paper per unit area, and the national standard stipulates that for impurities with an area of 0.3~1.5m㎡, the qualified products shall not be more than 80/㎡, and the excellent products shall not be more than 60/㎡, while the beauty is only 9~12/㎡. The dust degree will seriously affect the smoothness of the paper and the uniformity of the thickness, and the national standard is also very strict on this, and impurities with an area greater than 1.5m㎡ are not allowed.
 
The quantitative amount of porcelain white paper is 85g/㎡, which also determines that its performance is better than that of Transmei 2008 in all aspects, and it is suitable for making formal documents such as contracts. However, the porcelain white is 250 sheets/pack, the number of a single package is small, the price is high, and the cost performance is not as good as that of Chuanmei 2008.
