Printing Control Apparatus for Piled Work Instruction Sheets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In on-demand printing, the collation between work instruction sheets and work-in-process products is time-consuming and prone to human error, as separate sheets are often used for each product, requiring operators to manually match and handle them correctly to prevent mistakes during post-processing.
Innovation Solution
A printing control apparatus that performs layout processing to output work instruction sheets and printout matter in a piled state, using impositioning to ensure they are handled together after post-processing, reducing the need for manual collation by integrating the sheets during the printing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate work instruction sheets are printed for each product, then information completeness is improved, but manual collation time and error rate increase
Solution Approach 1:
The patent merges the work instruction sheet with the product by printing both on the same physical sheet. The work instruction sheet is integrated into the product structure, eliminating the need for separate sheets and manual collation. This is achieved by positioning the work instruction sheet content within the product layout, so that after cutting, the instruction sheet remains attached to or aligned with the corresponding product unit.
Solution Approach 2:
The patent performs preliminary action by pre-positioning the work instruction sheet content during the printing layout phase. The instruction sheet is prepared in advance with predetermined positions and orientations that will align correctly with the product after cutting. This preliminary arrangement eliminates the need for subsequent manual collation operations.
2Loss of information
If work instruction sheets are printed on normal-sized sheets, then information display is improved, but handling difficulty increases during post-processing
Solution Approach 1:
The patent applies local quality by adapting the work instruction sheet to the specific size and shape requirements of the product. Instead of using a universal normal-sized sheet, the instruction sheet is customized to match the product dimensions, making it easier to handle during post-processing operations. The instruction sheet content is positioned and sized to correspond with the specific product being produced.
Solution Approach 2:
The patent segments the work instruction sheet content to correspond with specific product units. By dividing the instruction sheet into sections that align with individual products after cutting, each product unit comes with its own relevant instruction information. This segmentation makes handling easier as operators only need to attend to the specific product and its associated instructions rather than managing separate full-size sheets.
3Quantity of substance
If multiple products are laid out on one sheet, then sheet utilization is improved, but identification complexity increases
Solution Approach 1:
The patent uses asymmetry in the layout arrangement to distinguish between different products on the same sheet. Each product unit is positioned with unique orientation, size, or pattern characteristics that make it identifiable. This asymmetric arrangement allows operators to easily distinguish between different products even when multiple are printed on one sheet, preventing confusion during handling and post-processing.
Solution Approach 2:
The patent employs color changes or color-coded elements to identify different products on the same sheet. Each product unit may have distinctive color markings, color-coded borders, or color variations in the work instruction sheet content that correspond to the product type. This visual differentiation makes product identification simple and rapid, allowing operators to quickly locate and handle the correct products without confusion.
Data Source
AI summary
A printing control apparatus performs a layout processing that generates print data on which data of products and data of a work instruction sheet are laid out based on information on first post-processing performed for a plurality of printout sheets that are printed using the generated print data, and instructs a printer to print the generated print data on the plurality of printout sheets. In the layout processing, the data of the products and the data of the work instruction sheet are laid out based on an order that the products and the work instruction sheet are discharged from the first post-processing, so that the work instruction sheet discharged from the first post-processing is output on the products discharged from the first post-processing in a piled state as the results of performing the first post-processing for the plurality of printout sheets on which the generated print data is printed.
