Flat Article Printing Layout with Integrated Cutting Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing flat printed articles result in significant waste and machine time due to the need for predetermined box sizes and separate cutting paths, which are inefficient when dealing with irregularly shaped images or varying image sizes on the same material, and require multiple file processing steps.
Innovation Solution
The method involves creating a file that associates each image with its cutting pathway and reference crosses, allowing for optimal pagination on a panel of varying sizes, where the cutting pathways are defined in relation to the image positions and rotations, and only the printing file is loaded into the RIP software, eliminating the need for a separate cutting file and enabling deformation correction during cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If predetermined box sizes are used for all images, then the printing layout is simplified and easier to manage, but significant waste of material occurs when dealing with irregularly shaped images or varying image sizes
Solution Approach 1:
The patent divides the sheet into multiple zones, each zone containing one or more images with their specific cutting paths. This segmentation allows each image to be optimized independently within its zone, enabling tight fitting around irregular shapes while maintaining overall layout organization. The zones are arranged to maximize material utilization by considering both image dimensions and cutting path requirements.
2Manufacturing precision
If separate cutting files are created for each image, then precise cutting paths can be defined, but machine time increases due to processing multiple large files
Solution Approach 1:
The patent merges the printing file and cutting file into a single integrated file structure. Each zone in the file contains both printing information and cutting path information, eliminating the need to process separate files. This integration maintains precise cutting paths while reducing machine processing time by handling all data in one file, avoiding redundant operations.
3Productivity
If different images are cut from the same sheet using the same printing layout, then the process is standardized and faster, but waste increases when images have different dimensions
Solution Approach 1:
The patent introduces dynamic zone configuration where the number, size, and arrangement of zones are automatically adjusted based on the specific images to be printed. Unlike fixed predetermined layouts, the zones are dynamically optimized for each production run, allowing tight fitting around images of varying sizes and shapes while maintaining standardized processing procedures. This dynamic adaptation reduces waste without sacrificing production efficiency.
4Adaptability or versatility
If boxes are made larger to accommodate irregular image shapes, then all images can be cut from the same sheet, but the surface area of waste increases considerably
Solution Approach 1:
The patent applies local quality optimization by creating zones with specific dimensions and arrangements tailored to the characteristics of individual images or groups of images. Rather than using uniform large boxes for all images, each zone is locally optimized to fit its contained images tightly, considering their specific shapes, sizes, and cutting path requirements. This local optimization minimizes waste area while maintaining adaptability to irregular shapes.

AI summary
Starting from a virtual representation of a flat-developing component, the method identifies and subsequently memorises at least an assembly constituted by an image, a closed line containing the image, and reference crosses associated thereto; the assembly is paginated in the virtual representation such as to define an intermediate file from which a printing file is obtained with which an RIP software program can be loaded to pilot a printing machine. If the component is to be cut, with the aim of obtaining articles bearing relative images, data is obtained from the intermediate file for managing a cutting machine which cuts the component along the closed line.
