Study on the Spot Color Matching of Offset Ink;

Study on Automatic Registration of Sheet-Fed Offset Press;

Several printing technologies used to print T shirt were introduced,such as offset printing,drain printing,raised foaming printing and etc.

PS plate as the current offset printing plate material performed significantly a bright spot,its bumping development du.

In high speed offset printing,unstable performance of bailer has adverse effect on the quality of presswork.

Design of electric control on teaching and demonstrating system for engagement and disengagement device of offset press;

Design and research on paper-feeding mechanism of high-speed offset press;

Electronic drive in offset press for continuous stationery printing;

The article analysed the distribution of offset vibrateing rolling axial velocity in theory,and adopted the computer simulation to prove the theoretical calculation conclusion;to confirm the axial speed which started in the different positions with different axial velocity in the offset vibrateing rolling,thus causes the offset being different in the axial attack while starting.

With an aim at the inaccurate overprint problem by the sheet-fed multi-color offset,this paper presents the "new template matching algorithm" based on the template matching theory and statistics principle.
