JDF is the XML-based format for the job descripting and exchanging. Through the Parse of JDF document’s grammar and data structure, we have got the information of layout. Combined with technical features of cutting papers and experiences of artificial processing paths, this article have to analyze the characteristics of irregular layout, then put out a new complex algorithm of cutting path and solve the planning of irregular layout cutting path. Development a optimization software of paper cutter. The cutting software based on JDF digital workflow, can obtain layout information directly from the prepress, and then transmitted generate cutting program to the cutter, which reduced the error caused by manual measurement and improved the cutting accuracy and efficiency.
