Multilayer Printed Matter Inkjet Printing and Cutting Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multilayered printed matter production requires lengthy printing times and significant operator workload due to the need for manual relocation of printed media from printing devices to cutting machines, leading to extended working hours.
Innovation Solution
A system and apparatus that integrates an inkjet head, a medium cutting device, and a moving device controlled by a printing and cutting controller to automate the printing and cutting process, eliminating the need for manual media relocation by enabling relative movement between the medium, inkjet head, and cutting device, and incorporating a concealment layer to conceal patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual relocation of printed media from printing devices to cutting machines is required, then device complexity is reduced, but productivity decreases and operator workload increases
Solution Approach 1:
The patent combines the printing device and cutting machine into an integrated system where the printed media can be directly transferred from the printing device to the cutting machine without manual relocation. The moving device automates the transfer process, merging previously separate operations into a continuous automated workflow, thereby improving productivity while managing system complexity through functional integration.
Solution Approach 2:
The integrated system performs multiple functions (printing, transferring, and cutting) within a single automated workflow. The moving device serves as a universal component that enables seamless transition between printing and cutting operations, allowing the system to handle multiple tasks without requiring separate manual operations for each function.
2Manufacturing precision
If multiple layers are printed on the medium, then product quality and pattern visibility are improved, but printing time increases significantly
Solution Approach 1:
The system maintains continuous operation by automatically transferring the printed medium from the printing device to the cutting machine without interruption. The moving device ensures that the printing and cutting operations occur in seamless succession, eliminating idle time between layers and maintaining continuous productive action throughout the multilayer printing process.
Solution Approach 2:
The system prepares the medium for subsequent operations by completing the printing of all required layers before initiating the cutting process. The automated transfer mechanism pre-positions the printed medium for immediate cutting, ensuring that all printing operations are preliminary completed before the next major operation begins, thereby optimizing the overall process time.
3Extent of automation
If operator manually relocates printed medium, then automation level is reduced, but device complexity is lowered
Solution Approach 1:
The moving device acts as an intermediary component that bridges the printing device and cutting machine. It automatically handles the transfer of printed medium between these two devices, eliminating the need for manual relocation while managing system complexity through a dedicated transfer mechanism rather than fully integrating all device functions into a single complex unit.

AI summary
A multilayered printed matter is made up of a plurality of layers formed on a medium, including a front layer and a back layer with patterns printed thereon, and a white layer and a black layer interposed between the front layer and the back layer so as to conceal the back layer to be invisible from the front-layer side. The system for producing the multilayered printed matter includes a computer that executes a printing step of moving the medium and an inkjet head relative to each other using a moving device and printing the front, back, white, and black layers on the medium using the inkjet head, and a cutting step, subsequent to the printing step, of moving the medium and a cutting blade relative to each other using the moving device and cutting the medium using the cutting blade.
