Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the Print On Demand market, commercial printing companies face inefficiencies and downtime due to mismatched printing conditions between client requests and device settings, leading to errors and delayed recognition of sheet size differences, which hinder timely delivery of small print jobs.
Innovation Solution
A print control device with a prohibition determination unit that prevents post-process functions other than cutting from being performed on sheets until they are cut to the desired size, and a workflow generation unit that arranges printing data to adapt to the available sheet size, allowing for efficient cutting and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the printing device stores sheets of a fixed sheet size, then the device can operate efficiently with standard sheet sizes, but it cannot accommodate client requests for different sheet sizes without causing errors and downtime
Solution Approach 1:
The system dynamically adjusts the sheet size configuration based on client requests. When a client requests a sheet size different from what is stored in the printing device, the system automatically determines whether to cut the stored sheet or rearrange drawing data, and updates the workflow accordingly. This dynamic adaptation allows the system to maintain high productivity while serving diverse sheet size requirements.
Solution Approach 2:
The system changes the effective sheet size parameter by cutting stored sheets into smaller sizes or by rearranging drawing data to fit different output dimensions. The prohibition determination unit modifies the workflow parameters to prevent post-processing functions that would be invalid after cutting, thereby adapting the printing process to match client-specific sheet size requirements without sacrificing operational efficiency.
2Reliability
If the system allows all post-process functions to be performed on sheets, then printing operations can be completed quickly, but errors occur when sheets are cut to different sizes
Solution Approach 1:
The prohibition determination unit performs preliminary determination before allowing post-processing functions to execute. It checks whether the sheet will be cut to a different size and preemptively prohibits post-process functions that would be invalid after cutting. This preliminary action prevents errors before they occur, ensuring printing accuracy while minimizing processing time by avoiding post-error correction.
Solution Approach 2:
The system implements feedback control by continuously monitoring the workflow and sheet size configuration. When a cutting operation is detected or anticipated, the system provides feedback to the prohibition determination unit, which then adjusts the allowed post-process functions accordingly. This feedback mechanism ensures that only valid post-process functions are executed, maintaining printing accuracy while optimizing processing time.
3Reliability
If the operator manually checks and adjusts sheet size settings, then printing errors can be prevented, but downtime occurs due to manual intervention and delayed recognition of sheet size differences
Solution Approach 1:
The system performs self-service by automatically determining the appropriate workflow based on the stored sheet size and client request. The prohibition determination unit autonomously checks whether cutting is needed and automatically adjusts the workflow without requiring manual operator intervention. This self-service capability maintains sheet size accuracy while eliminating downtime associated with manual checking and adjustment.
Solution Approach 2:
The system replaces manual mechanical checking and adjustment processes with automated electronic determination. The prohibition determination unit uses electronic workflows and automated decision-making to check sheet size compatibility and determine necessary adjustments, eliminating the need for manual operator intervention. This substitution maintains high reliability in sheet size accuracy while completely eliminating downtime for manual adjustment.
4Productivity
If the printing device performs post-process functions before cutting, then processing can be completed efficiently, but the post-process functions cannot be performed correctly on cut sheets
Solution Approach 1:
The prohibition determination unit performs preliminary determination to establish the correct sequence of operations. It determines whether cutting should be performed before or after post-process functions based on the specific workflow and sheet size requirements. This preliminary action ensures that post-process functions are only performed on sheets in their correct final state, maintaining manufacturing precision while optimizing processing speed through proper sequencing.
Solution Approach 2:
The system dynamically adjusts the processing sequence based on the specific printing job requirements. When cutting is required, the system dynamically reorders the workflow to perform cutting before post-process functions, or prohibits post-process functions that would be invalid after cutting. This dynamic sequencing maintains both high productivity and manufacturing precision by adapting the process order to the specific job requirements.

AI summary
A print control device includes a prohibition determination unit, when a first sheet size of a sheet stored in a printing device is different from a second sheet size designated by an operator, preventing, when determining that the second sheet size of the sheet can be generated by cutting the sheet having the first sheet size, an execution of a post process function other than cutting in the printing device; and a workflow generation unit generating a workflow including operational steps of causing a cutting device to cut the sheet having the first sheet size to obtain the sheet having the second sheet size, and causing a functional device other than the cutting device to perform the post process function on the printing output after cutting the sheet having the first sheet size.
