Solution Overview
Problem
Inkjet recording apparatus face challenges in achieving high transfer efficiency of intermediate images onto recording mediums, particularly due to issues like feathering and incomplete transfer, which affect the quality and speed of image output.
Innovation Solution
An auxiliary liquid containing water-soluble resin and wax particles is applied to the intermediate transfer member, with temperature adjustments to ensure the wax particles melt and solidify at specific points, enhancing adhesion between the intermediate image and the recording medium, thereby improving transfer efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If an intermediate image is transferred at high speed using a transfer system, then image output speed is improved, but feathering occurs due to ink spreading along fibers
Solution Approach 1:
An auxiliary liquid containing water-soluble resin and wax particles is introduced as an intermediary substance between the intermediate image and the recording medium. This auxiliary liquid mediates the transfer process by providing controlled adhesion and release properties, enabling high-speed transfer without feathering while maintaining image quality.
Solution Approach 2:
The auxiliary liquid undergoes parameter changes through temperature control during the transfer process. By adjusting temperature, the wax particles transition between solid and liquid states, dynamically controlling adhesion strength to prevent feathering during high-speed transfer while ensuring complete image transfer.
2Strength
If conventional auxiliary liquids containing water-soluble resin are used, then scratch resistance is improved, but transfer efficiency remains insufficient due to incomplete transfer and image division
Solution Approach 1:
The auxiliary liquid is formulated as a composite material containing both water-soluble resin and wax particles. The water-soluble resin provides scratch resistance and adhesion, while the wax particles enable controlled release and improve transfer completeness. This composite structure simultaneously achieves high transfer efficiency and image strength without the drawbacks of conventional single-component auxiliary liquids.

AI summary
A method of recording an image on a recording medium by applying an auxiliary liquid containing a water-soluble resin and wax particles to an intermediate image formed on an intermediate transfer member, bringing the intermediate image into contact with the recording medium at a temperature higher than a melting point of the wax particles, subsequently peeling off the intermediate image from the intermediate transfer member at a temperature lower than the melting point of the wax particles and transferring the intermediate image onto the recording medium. The method can improve the efficiency of transferring the intermediate image from the intermediate transfer member onto the recording medium.
