Besides,by combining PS block with wooden or paper block,both flat and convex or concave prints can be made,which brings us more choices in the use and development of printing blocks.

At condition temperature 20~25℃ and humidity 60%~65%, the author using IGT printability tester(model AIC2-5) made a experimental study of printing ink′s absorbing characteristic to common printing paper-glazed printing paper and coated art paper.

This paper introduces the application and characteristics of PCC as a filler and coating pigment in coated art paper production.

The influence of offset paper and ink performance on print gloss was studied.

The base properties of five offset paper was measured,and the penetration depth,after printing,was tested when the same ink enter into these paper.

The surface strength of offset paper can be increased markedly by treating the paper surface with a low temperature plasma prior to surface sizing.

Testing Ash of Art Paper and Effect of Ash on Art Paper Physical Properties;

This paper reveals the reason why the US government chooses the anti-subsidy case of art paper to impose the anti-subsidy tax on China,and the deeper purpose of US government s accusation on China of subsidy,as well as the inspiration and consideration arising from this case of how Chinese government can preserve the legal right under the framework of DSU of WTO.

The results showed that the properties of art base paper was not affected by blending large of P-RC APMP,on the contrary,some properties were improved.
