Experimental Study on the Ink Jet Printing Quality Improvement of Ordinary Printing Paper with Poly vinyl Alcohol

摘要

At present, the quality of ink-jet printing depends to a great extent on the surface quality of the printing material. The commonly used high gloss paper and coated paper have excellent color rendering results, but the cost is higher, which affects the further application of ink-jet printing. Therefore, the low cost ordinary printing paper is used as the base paper, and the surface of the base paper is coated with polyvinyl alcohol solution to improve the surface quality of the base paper. Preparation of test specimens for color strength condition of different coating solution concentration and coating were tested and compared with the base paper, color intensity was the standard color is obviously improved; printing characteristic curve of the samples were tested and analyzed, compared the change trend of density in the actual printing process of the various. It is found that the printing quality can be improved obviously by adopting the above process.
