Recording Control Device Edge Dot Size Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording technologies face issues with barcode image quality due to bleeding and spreading of dots at the edges on the recording medium, degrading the overall quality of the printed image.
Innovation Solution
A recording control device that includes an edge detection unit and a recording control unit, which generates dot data to use smaller dots for the internal region relative to the edge region, or performs dot-off recording in the internal region to prevent bleeding and spreading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dots are used for recording in the internal region with the same size as edge region dots, then recording coverage is improved, but dot bleeding and spreading occurs at edges degrading image quality
Solution Approach 1:
The patent applies different dot sizes in different regions of the image. Specifically, smaller dots are used in the internal region (first dot size) while larger dots are used in the edge region (second dot size). This local differentiation prevents dot bleeding and spreading at edges while maintaining adequate recording coverage in the internal region, thereby resolving the contradiction between image quality and dot spreading.
2Object-generated harmful factors
If smaller dots are used in the internal region to prevent bleeding, then dot spreading is reduced, but recording density and coverage may be insufficient
Solution Approach 1:
The patent strategically places smaller dots in the internal region where dot spreading is less critical, and larger dots at the edges where spreading would most degrade image quality. This localized approach ensures that recording density is maintained where needed while preventing spreading at vulnerable edge regions, thus resolving the contradiction between preventing dot spreading and maintaining recording density.

AI summary
A recording control device that controls a recording device that discharges a dot to perform recording includes an edge detection unit configured to detect an edge of an image represented by image data, and a recording control unit configured to generate dot data specifying the dot based on the image data and to cause the recording device to perform recording based on the dot data. The recording control unit causes an internal region, located on an inner side of an edge region including the edge of the image, to be recorded using a dot having a smaller size than that of a dot used for recording of the edge region, or to be dot-off.
