There is little difference in the performance of various brands of copy paper, and Piovan is the most mature, well-known and complete brand among them.
 
Piovan copy paper uses the original HDPrint technology, which is based on the principle that after the paper is specially calendered, the fibers are extruded, and the toughness and surface flatness are enhanced, so that when printing or writing, the ink is quickly locked on the surface of the paper instead of penetrating into the internal structure. More ink is left on the surface for sharper lines, sharper definitions, and brighter colors, resulting in better visuals whether printed in black and white or color. In addition, the high degree of smooth paper surface greatly reduces the wear of the printer's fuser roller and extends the life of the machine.
 
The biggest difference between Red Pivan, Blue Pivan, and Green Pevan is quantification and smoothness. There are two kinds of red Baiwang quantitative, 85g/㎡ and 100g/㎡, which are much thicker than general A4 paper, coupled with high smoothness, so it is especially suitable for color digital printing, high-quality picture printing, used as covers, leaflets. Blue Piveng has medium smoothness, which is suitable for printing and copying important documents. The quality of Green Piovan is the worst of the three, but the price is also low, and it is suitable for high-speed printing and copying in large quantities.
