| Cutting is the essential work in the printing production process, and the paper needs cutting before and after printing. The paper cutter is the capital equipment of cutting. This paper is considered from the layout overall arrangement of the printed sheet and the demand of the cutting positioning mainly, and offers the optimized cutting scheme before the paper cutter begins to cut the printed sheet, in order to assure working efficiency and cutting quality of the paper cutter. The concrete content of the paper is summed up as follows:1) Combine the theory of cutting technology and real working state, analyze and summarize the laws and characteristics of the layout overall arrangement of the printed sheet, and the goal of the optimized cutting algorithm is to make count of cutting and time of rotating and positioning of the printed sheet on work table least.2) Adopt Visual C++6.0 as the instrument of the software development, and program the optimized cutting software. It has three major function module, namely the input module, the store module and the cut module to realize the optimized cutting algorithm.3) The software has good user's interface, users input the parameter of the printed sheet and the label and confirm the layout overall arrangement of the printed sheet. It can offer the optimized cutting scheme and show the cutting line and the cutting order. That can make user clear to the cutting result of the printed sheet, consequently improve productionefficiency and cutting quality of cutting work.The development of cutting software makes the workflow of the paper cutter intelligent, therefore improve the grade of the paper cutter of our country and shorten the disparity with the foreign paper cutter. The optimized cutting algorithm can not only be applied to solve the cutting problem of postpress, but also be applied to solve the similar problems of other industries, for instance: the optimized cutting problem of processing industry, such as metal or the glass, etc. |
