Offset paper is specially treated with smooth surface and high whiteness optical effects, which enable the paper to meet the very high requirements of colors from the printing customers, overall printing quality is enhanced by the reproduction of the vivid colors. Strictly controlled surface strength and the paper dust during production process help the printers to minimize the problems of picking and dusting to ensure the working efficiency. Has consistent paper quality and fine printing quality.
