White ptinting paper generally uses the right amount of bamboo pulp bleaching chemical coniferous wood pulp and makes.When processing offset paper, loading, sizing, some high-grade woofree paper, surface sizing, calender.woodfree paper when printing with ink painting is the principle of balance, so we need paper has very good water resistance, dimensional stability and strength.More than woodfree paper is used to color print, to make the ink is tonal, can recover the manuscript requires a certain whiteness and smoothness.

Product Usage
Bond paper commonly used for printing brochures, color illustrations, trademarks, cover, end paper, high-grade books and the primer, etc. In recent years, as people culture, improvement of living standards, books materials also to the development of high grade, use the offset paper printing books and periodicals, such as this more and more.Because woodfree paper has strengths such as qualitative white, crisp, smooth, delicate, text books after the primer is made clear, books and periodicals, plain is out of shape not easily compared with the letterpress, newsprint books, class, all the good reputation among readers and use easily.
