Inkjet Recording Apparatus Code Image Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When recording barcode images and non-code images together on a single sheet of paper using an inkjet printer, the deformation of paper due to ink landing can lead to variations in ink landing accuracy, resulting in deteriorated recording quality and potential reading errors, especially when the non-code image has a high ink density.
Innovation Solution
An inkjet recording apparatus and method that determines the presence of both code and non-code images in a passing region and performs separate recording processing to ensure that the code image is recorded first, minimizing the impact of the non-code image on the paper's flatness and accuracy, by controlling the head and motor movements based on image data stored in memory.

Engineering Contradiction Analysis
1Productivity
If both code image and non-code image are recorded in the same passing region simultaneously, then recording efficiency is improved, but recording precision of code image deteriorates due to paper deformation from high ink density areas
Solution Approach 1:
The recording process is divided into multiple passes. The code image is recorded in a first pass, and the non-code image is recorded in a second pass. This segmentation separates the recording of high-precision code regions from high-ink-density non-code regions, preventing paper deformation from affecting code image quality while maintaining overall recording efficiency.
Solution Approach 2:
The code image is recorded first before the non-code image in the same passing region. This preliminary action ensures that the code image, which requires high precision, is recorded on flat paper before any deformation occurs from subsequent non-code image recording with high ink density.
2Manufacturing precision
If separate recording processing is performed for code image and non-code image, then recording precision is improved, but recording time increases
Solution Approach 1:
The image data is segmented into code image portions and non-code image portions. The controller identifies these regions and schedules their recording in separate passes, with code images recorded first. This segmentation enables precision recording while minimizing time loss by processing regions in an optimized sequence rather than requiring complete separation.

AI summary
A controller determines: based on image data, whether both a code image and a non-code image are included in an image to be recorded in a passing region of a recording medium; and in response to determining that both images are included, during a first relative movement of a head, performs first separate recording processing of controlling the head and a motor to record at least part of a portion of the code image included in the passing region without recording a portion of the non-code image included in the passing region; and during a second relative movement which is performed after the first relative movement, performs second separate recording processing of controlling the head and the motor to record at least part of the portion of the non-code image included in the passing region without recording the portion of the code image included in the passing region.
