Solution Overview

Problem

Conventional textile printers using the multipath method leave unprinted portions at the end of a printed image when the printing operation is temporarily stopped, leading to a decrease in the value of the printed material due to incomplete images.

Innovation Solution

An inkjet recording device and method that includes an image formation section forming raster lines in a scanning direction and a control section that temporarily stops the printing operation to complete the back end portion line formation, preventing unprinted areas when stopping and resuming printing, and optionally allowing user input for temporary stops and displaying operation selection screens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the printing operation is temporarily stopped in the middle during multipath recording, then the seam portion can pass through the inkjet head moving path, but an unprinted portion is generated in the back end portion of the printed image

Engineering Contradiction:

Improveability to handle fabric seam portionsVSAvoidcompleteness of printed image

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The control section performs a back end portion line formation process before temporarily stopping the printing operation. This preliminary action ensures that the raster line is completed in the back end portion of the printed image, preventing unprinted portions from being generated when the printing operation is temporarily stopped due to seam portions.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the multipath recording method is used to print fabric, then printing efficiency is improved, but unprinted portions are generated at the end of printed images when printing is temporarily stopped

Engineering Contradiction:

Improveprinting efficiencyVSAvoidcompleteness of printed image

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If a recording line is formed to prevent unprinted portions at the end of printing, then printing quality is improved, but printing time is increased

Engineering Contradiction:

Improvequality of printed imageVSAvoidprinting time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The control section performs the back end portion line formation process only in the back end portion of the printed image where unprinted portions would be generated, rather than forming recording lines throughout the entire printed image. This localized approach maintains printing quality while minimizing additional printing time.

Inventive Principle:

Principle #3Local quality

AI summary

The advantage of the invention is to provide an inkjet recording method and the like in which an unprinted portion due to a multipath method is not left in a back end portion of a printed image and the value as a printed material is not undermined in a case where a printing operation by a multipath method is temporarily stopped in the middle and the printing operation is resumed after feeding a recording medium. A printing operation is temporarily stopped after conducting a back end portion line formation process for forming a raster line so as to prevent an unprinted portion due to a multipath method from being left in a back end portion of a printed image which has been printed halfway when temporarily stopping the printing operation in the middle.
