Printing system and control device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In printing systems where pre-processing and post-processing steps are performed in addition to the printing step, managing the operation of each step effectively becomes challenging, especially when unintended results occur due to the combination of multiple steps.
Innovation Solution
A printing system with a control device that manages the conditions of the printing step and other steps by associating step conditions with results, allowing for adjustments in the conditions of non-printing steps based on the state of the printed matter to achieve the target product state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple steps (pre-processing, printing, post-processing) are executed in combination, then the productivity and functionality of the printing system are improved, but the difficulty of managing and controlling each step increases
Solution Approach 1:
The patent merges the management of multiple independent steps (pre-processing, printing, post-processing) into a single integrated control device that manages all steps collectively. This allows the system to handle multiple steps efficiently while maintaining centralized control, resolving the contradiction between improved productivity through multi-step processing and the increased complexity of managing each step individually.
Solution Approach 2:
The control device is designed with universal functionality to manage diverse types of steps (pre-processing, printing, post-processing) with different parameters and requirements. This multi-functional control approach enables the system to handle various step combinations without requiring separate management systems for each step type, thus improving productivity while keeping management complexity manageable.
2Measurement precision
If conditions of each step are individually managed, then the control precision of each step is maintained, but the ability to adjust conditions based on results from other steps is reduced
Solution Approach 1:
The control device implements feedback mechanisms where results from one step (e.g., printing step) are used to adjust conditions of other steps (e.g., post-processing step). This feedback loop maintains control precision by ensuring each step operates within specified parameters while simultaneously improving adaptability by allowing dynamic adjustments based on actual step outcomes.
Solution Approach 2:
The system transitions from static individual step management to dynamic integrated management where step conditions can be adjusted in real-time based on results from other steps. This dynamic approach allows the control device to adapt step conditions flexibly while maintaining precision through centralized monitoring and adjustment capabilities.
3Manufacturing precision
If a predetermined step is executed to correct unintended results, then the manufacturing precision of the final product is improved, but the total processing time and loss of time increase
Solution Approach 1:
The control device performs preliminary actions by predicting potential unintended results from printing steps and proactively adjusting post-processing step conditions before the printing is completed. This preventive approach improves manufacturing precision by avoiding defects rather than correcting them later, while reducing total processing time by eliminating the need for separate correction steps.
Solution Approach 2:
The system skips time-consuming manual intervention and iterative correction cycles by implementing automated real-time adjustment of step conditions. The control device rapidly processes step results and adjusts subsequent step parameters automatically, improving manufacturing precision while minimizing the time loss that would otherwise be spent on manual quality control and rework.

AI summary
The disclosure more appropriately creates a product of printing closer to the target state. A printing system (10) that creates a product of printing includes a printer (16) that is a printing apparatus that executes a printing step, a steaming machine (18) that is a device for a predetermined step that is a device that executes a predetermined step, and a control device (12); where the control device (12) acquires printed matter information that is information indicating a state of a printed matter obtained by performing the printing step by the printer (16), and adjusts a condition of a step to be executed in the steaming machine (18) based on information indicating a state of the target product and the printed matter information such that a product in a state closer to a state indicated by target product information is obtained.
