The principle of offset printing is the graphic part lipophilicity and the blank part oleophobic hydrophilic. Based on the ink-water balance theory, this paper mainly discusses the base paper and the coating formulations of paper-based printing plate. In this paper the properties of the paper-based printing plate of the different coating formulations were detected and evaluated, meanwhile these plates were tested in the offset printing. Based on the detection of print quality, plate coating performance and the number of copies printed, the base paper and coating formulations of this plate was be determined. The results of this study for this plate have some significance in the actual production.

The application of hydrated calcium silicate as filler in paper from wheat straw pulp is studied in this paper. It shows that that with the increase of dosage of hydrated calcium silicate, the stiffness of paper improves, and the whiteness and the printing color density of paper improve, but the tightness and tensile strength of paper decrease. When the dosage of CPAM is 0.45 g/kg, the tightness, tensile strength, tearing index, whiteness and printing color density reach the large value. Paper ash content increased with the increase of amount of hydrated calcium silicate, but paper ash gains is not big after the dosage of hydrated calcium silicate reaches 20%.

Filter paper splash procedure is a kind of measuring means to raindrop size. It is used widely and operated briefly and its cost is low. The article mainly introduces the influence of different heights to the stain diameter and the relationship between stain diameter and the raindrops. According to the experiment, the relation between the stain diameter and the raindrops is d=0.478D0.610.it is the research foundation of filter paper stain method. According to the data from Fangxian area using the method of filter paper splash procedure, we can conclude that the raindrop kinetic energy has a positive relationship with rainfall intensity. The research is useful for measuring the water and soil loss.Water and soil loss is one of the global environment problems. The most important factor which can cause water and soil loss is rainfall. The research on raindrop kinetic energy is important for the further analysis of water and soil loss. A classical approach for the research on raindrop kinetic energy is paper splash procedure. The relationship between stain diameter and raindrop diameter shall be calibrated in this approach. In general, influences from titrated water drop height and stain diameter are not considered in the calibration process. In this experiment, influences of rain drop height on stain diameter are researched in the stain calibration, settling basis for the research on local volume of water and soil loss.

The Paper studied the effects of pigments and base paper on binder migration and affected factors. The z-direction distribution of the coating binder which was tagged with Br in coating layer and its concentration in coating surface were examined quantitatively by using SEM-EDXA and ESCA analysis. The results showed that the increase of the ratio of calcium carbonate in the pigment content, coating surface binder concentration increased, and coating surface binder concentration increased with the increase of particle size of pigments. The result also indicated to small base paper absorbency, coating surface has high binder migration level, the coating layer bottom (base paper direction) has low binder concentration. To high absorbency base paper, the opposite is true.

A nano-material named opal blended with polymer, then were added into slurry, after a series of special paper-making process, the rice paper releasing anion was successfully prepared by us. By test of SEM, we observed nano-structure morphology in the image of opal particle and rice paper sample. A series of mechanical properties had been tested as GB18739 or QB/T3515 standard. After testing of anion concentration, maximum of rice paper reached -9510cm-3，meet the needs of human health. There is no doubt opal is a kind of environmental material for human health.

The study on the start-up of the pilot-scale immobilized and suspended biomass combination processing to treat the comprehensive effluent from a wheat straw pulp and paper plant was performed. The carrier packing selected in this experiment is a new type of microbial carrier (modified polyurethane foam plastic packing) which dosing rate was 20% of the reactor volume. The low quantity of inoculation sludge way is used to start the system. The test results show that the removal efficiency of COD and SS by the immobilized and suspended biomass combination technology system after a weak or so can be stable, as the effluent SS was below 50mg/L, the removal rate of 95% or more and the effluent COD was below 260mg/L, the removal rate of 85% or more. From start to 10th day, the attached sludge concentration on biomass conversion was more than 20g/L, while the microscope observation to biological adherent microbes suspended sludge and carrier phase indicated abundant microbial species. The fact indicates that the start-up can be finished in 10 days.

The coating binder migration and concentration in z-direction of coating layer especially in coating surface influence the coated paper printing properties. The results indicated that with the increase of coating surface binder migration, the coated paper opacity decreases, and the K&N value decreases. The relationship of K&N value and binder concentration in surface of coating layer was linear, which indicated that compared to binder dosage concentration in coating color, the K&N value and coating surface binder concentration has higher correlation. The more uniform the binder distribution in cross section of coating layer, the greater the IGT.

Paper-cut animation is rooted in Chinese folk culture, which is an important constituent part of Chinese animation. This article has analyzed the own artistic charm of paper-cut animation, from the early traditional manufacturing method and its insufficiencies as well as the questions we faced, to details of the new manufacturing method after the application of modern computer technology to the paper-cut animation. Also the article emphasizes the introduction of manufacturing advantages after the computer technology applied to the paper-cut animation, as well as discussions on application value of paper-cut animation in business and service domains, etc.

The surface topography and properties of coating layer have an important influence on penetration and distribution of the print ink. In this research, the main objective was to investigate the effect of binder migration on the coating surface microstructure. The surface microstructure was explored in the method of numerical and visual analysis using mercury porosimetry measurement, scanning electron microscopy (SEM) and atomic force microscopy (AFM). The findings indicated that the binder migration on the coating surface affected the pore size, depth and distribution of the coated paper surface. The little binder migration in the consolidation phase of coating color made a contribution to the forming of the coating layer, which made the coating surface more smother to printing performance.

In this study, paper sludge ash, a waste from pulp and paper industry was used as a filler in fabricating Plaster of Paris/paper sludge ash composites. Various percentage of paper sludge ash was used, namely 1wt.%, 3wt.%, 5wt.% and 7wt.%. The effect of paper sludge ash on the compressive strength of the Plaster of Paris was studied. The mixed powder of paper sludge ash and Plaster of Paris were form into a 6 mm diameter and 12 mm height cylindrical samples. The composites were characterized theirs density where it shows that the density decreased as the amount of paper sludge ash increased. The compressive strength of the composites also decreased from 11.67 MPa without paper sludge ash addition to 0.50 MPa at 7wt.% paper sludge ash. However, the requirement of strength for Plaster of Paris in industry is between 8.96 MPa to 20.68 MPa. From the SEM observation, sample contain higher percentage of paper sludge ash exhibited more porosity. Therefore with the addition of 1wt.% of paper sludge ash into Plaster of Paris can be a promising construction material.
