Imposition Information Generator Using Folding Templates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generating imposition information for printing sheets to be folded into sections is complex due to the large number of combinations of page size, folding methods, orientation of bag-like portions, and stitching sides, making it difficult to promptly handle changes in conditions.
Innovation Solution
An apparatus with a memory for storing folding template information and an input receiving part for selecting page size, orientation, and stitching side, which generates imposition information easily by using pre-prepared folding template information, including cutting positions and overlaying instructions, and displays these instructions for easy generation and setting of folding machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-generation of multiple sets of imposition information for all combinations of page size, folding method, orientation, and stitching side is performed, then all possible conditions can be covered, but the number of sets becomes large making generation and management complicated and increasing the risk of wrong selection
Solution Approach 1:
The patent segments the imposition information generation into two distinct phases: pre-generation of folding template information (independent of specific book parameters) and on-demand generation of final imposition information (dependent on specific book parameters). This segmentation allows the system to maintain versatility while reducing the complexity of managing multiple complete imposition information sets.
Solution Approach 2:
The patent applies preliminary action by pre-generating and storing folding template information that is independent of specific book parameters such as page size, number of pages, folding method, and stitching side. These templates are prepared in advance and can be quickly combined with specific parameters to generate the final imposition information, avoiding the need to pre-generate all possible combinations.
2Adaptability or versatility
If pre-generation of multiple sets of imposition information is performed, then all conditions can be covered, but the risk of making wrong selection increases when choosing from many sets
Solution Approach 1:
By segmenting the information into parameter-independent folding templates and parameter-specific combination data, the system eliminates the need to select from multiple complete imposition information sets. The templates serve as a reliable foundation that, when combined with the specific parameters, guarantee correct imposition information generation.
Solution Approach 2:
The system uses folding template information as a reusable template that can be copied and combined with different parameter sets to generate imposition information for various book types. This template-based copying approach ensures reliability by using a verified foundation rather than requiring selection from multiple potentially incorrect complete sets.
3Device complexity
If imposition information is generated only when needed, then management complexity is reduced, but if conditions change after generation, complicated work needs to be done again to generate new imposition information
Solution Approach 1:
The patent applies preliminary action by pre-preparing folding template information that can be quickly recombined with new parameter sets when conditions change. When a condition change occurs (such as changing the stitching side), the system can rapidly generate new imposition information by combining the existing templates with the updated parameters, rather than starting from scratch.
Solution Approach 2:
The system creates a dynamic approach where the folding template information remains static and pre-prepared, while the final imposition information is dynamically generated by combining these templates with current parameter settings. This allows for quick adaptation to condition changes without regenerating everything from scratch.
4Reliability
If complete imposition information is generated from scratch when conditions change, then accuracy can be maintained, but the work becomes complicated and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-generating folding template information that serves as an accurate foundation. When conditions change, the system combines these pre-verified templates with the new parameters to quickly generate updated imposition information, maintaining accuracy while significantly improving generation speed compared to starting from scratch.
Solution Approach 2:
By segmenting the generation process into template combination (fast) and parameter-specific customization (fast), the system achieves both speed and accuracy. The segmented approach allows the system to leverage pre-computed accurate template data rather than performing time-consuming complete regeneration.

AI summary
In an imposition information generating apparatus (2), folding template information (31) indicating an instruction to fold a print sheet is prepared in a memory (24) in advance. When generating imposition information (32), input of selection information including a page size of a book product, a selection whether bag-like portions in a section are to be located on the top or bottom of the section, and a selection which side of the section is to be stitched, is received. Then, the imposition information (32) for printing the print sheet which is to be folded into the section is generated on the basis of the folding template information (31) and the selection information in an imposition information generator (22). As above, by preparing the folding template information (31) in advance, it is possible to generate the imposition information (32) easily.
