This paper discusses the effects of different retention agent such as: CPAM, APAM, PAE+CPAM, cationic starch with high degree of substitution and modified starch on the reversible thermochromism materials in anti-counterfeiting paper retention rate, and then determined the optimum dosage of retention agent in the slurry. According to the anti-counterfeit paper color value, the mechanism of reversible thermochromism paper was studied. The experimental results show that when the slurry with retention agent, the reversible thermochromism materials in the anti-counterfeit paper retention increased significantly. This suggests that retention agent in pulp fiber has played the role of bridge and link, thus ensuring the security of reversible thermochromism paper.

IIndoor photo has been widely used in products of shopping malls publicity, light box advertising, wedding photography, posters, engineering and landscape effect picture, digital photo album, art photo, antiquing canvas and window advertising. PP synthetic paper which was the most common indoor photo materials was selected as the research object, and it was printed by the photo printing machine. A series of experiments were carried out according to its printability. The main parameters of PP synthetic paper such as solid density, dot gain and relative contrast were tested, which provided a theoretical and practical basis for digitization of indoor photo.

Paper based printing plate is one of printing plates used in eight mo octave or specifically offset printing machine. In the printing process, the printed plate wants to keep its shape by the pressure, the friction and tension. It needs to have good dimensional stability and good ink-water balance of coating. This paper discusses the influence of different coating formulations and coating process on the mechanical properties of paper-based printing plate. In this paper, the wet strength of paper-based printing plate of different formulations and different coating amount were tested. The study provided the theoretical basis for ink-water balance coating formulations of paper-based printing plate and the plate production.

Reversible thermochromism polyethylene sheet was prepared by the reversible thermochromism material and polyethylene particles using the method of melt blend. Then the color difference, test temperature and the mechanical properties of the reversible thermochromism sheet were tested. Using of electron microscopy in order to observe the details of the reversible thermochromism polyethylene sheet. Finally, this paper discusses the different amounts of reversible thermochromism materials on the polyethylene sheet relative color difference and mechanical properties. This study has some guiding sense over the application and the production of reversible thermochromism polyethylene sheet material.

Rare-earth europium complex is a UV photochromic materials. Fluorescent Polyethylene Sheet Material were prepared by the Rare-earth europium complex and polyethylene particles using the method of melt blend. Then the fluorescence of polyethylene sheet and the relative fluorescence intensity of the mechanical properties were tested. Finally, this paper discusses the different amounts of phosphor on the polyethylene sheet relative fluorescence intensity and mechanical properties. This study has some guiding sense over the application and the production of fluorescent polyethylene sheet material.

Ink-jet light-box cloth has been widely used in municipal engineering, supermarket, exhibition, hotel and other places, and played an indispensable role of advertising and decoration. There have been no unified parameters and standards for printing quality evaluation of ink-jet light-box cloth. To solve this problem, a group of researches were carried out according to its printability, which selected light-box cloth printed by inkjet. The parameters such as solid density, dot gain, relative contrast of the light-box cloth were tested and analyzed. Based on the results, the printing quality evaluation parameters were put forward. The purpose was to provide reference data for quality evaluation in light-box cloth printing industry.
