Recording device and recording method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording devices struggle with cutting thin or soft fabrics due to insufficient adhesion of ultraviolet curable ink, leading to issues like fraying, fluff generation, and difficulty in cutting or sewing.
Innovation Solution
A recording device equipped with an ink head for ejecting pigment ink and a curing process head for ejecting a curing process liquid that permeates and cures the fabric, enhancing the cutting strength and stability of the fabric.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If ultraviolet curable ink is ejected to the cut position, then the recording medium can be marked for cutting, but the cutting strength is insufficient and cutting becomes difficult or impossible when the recording medium is thin fabric or soft fabric
Solution Approach 1:
The patent changes the physical-chemical parameters of the ink by using a two-component system: Component A (ultraviolet curable ink with adhesive resin) and Component B (curing agent). This chemical parameter change enables the ink to penetrate fabric fibers and form strong bonds, resolving the contradiction between cutting precision and cutting strength in thin or soft fabrics
Solution Approach 2:
The patent creates a composite material system by combining ultraviolet curable ink with a separate curing agent. This composite approach allows the ink to achieve both marking function and enhanced mechanical strength through chemical bonding with fabric fibers, solving the problem of insufficient cutting strength
2Manufacturing precision
If ultraviolet curable ink is used for recording on fabric, then the image can be recorded on the surface, but fraying occurs from the cut surface and fluff is generated
Solution Approach 1:
The patent applies chemical parameter changes by introducing a curing agent that reacts with the ultraviolet curable ink's adhesive resin. This creates a strong chemical bond within fabric fibers, preventing fraying and fluff generation while maintaining accurate image recording on the fabric surface
3Ease of operation
If localized pulling force is applied during fabric transport, then the fabric can be positioned for printing, but distortion or wrinkles occur in the fabric material
Solution Approach 1:
The patent applies preliminary action by ejecting the two-component ink system before cutting or sewing operations. The ink penetrates and bonds with fabric fibers in advance, creating internal reinforcement that stabilizes the fabric structure and prevents distortion or wrinkles during subsequent handling and processing
4Ease of operation
If thin fabric or soft fabric is fed through a sewing machine, then sewing can be performed, but the fabric may twist or the needle may push rather than penetrate, causing sewing defects
Solution Approach 1:
The patent performs preliminary reinforcement by ejecting the two-component ink system onto the fabric before sewing operations. The cured ink creates strong bonds within fabric fibers, providing internal structural support that prevents twisting and enables needle penetration, thereby ensuring reliable sewing quality

AI summary
A recording device 1 includes a recording section 7 configured to record an image 2 on a medium 3 transported in a transport direction F based on image data 5 and a control section 9. The recording section 7 includes an ink head 71 configured to eject pigment ink 11 onto a fabric material 31 of the medium 3 and a curing process head 72 configured to eject curing process liquid 13 that cures the fabric material 31 in a state in which the fabric material 31 is permeated. The control section 9 executes a first control 91 for recording the image 2 onto the medium 3 by ejecting the pigment ink by the ink head 71 and a second control 92 for ejecting the curing process liquid 13 onto the curing target area 15 of the medium 3 by the curing process head.
