Data Processing Device for Embroidery Print Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embroidery and printing technologies fail to maintain the positional relationship between printed images and embroidered patterns on fabric due to fabric shrinkage during the embroidery process, leading to displacement of printed images relative to embroidered patterns.
Innovation Solution
A data processing device that corrects print and embroidery data to maintain the predetermined positional relationship between embroidery and print regions on fabric, considering fabric shrinkage, by using a data correction unit that adjusts the size and position of embroidery and print regions based on fabric type, thread type, and embroidery frame type, ensuring consistency and preventing displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If print data and embroidery data are generated from image data without considering fabric shrinkage, then the processing is simple and quick, but the positional relationship between printed image and embroidered pattern is lost due to fabric shrinkage
Solution Approach 1:
The patent applies preliminary action by calculating and applying shrinkage correction values to the embroidery data and print data before the actual embroidery and printing processes. The data correction unit pre-adjusts the coordinate information based on predicted shrinkage amounts, so that when the fabric is embroidered and printed, the positional relationships are maintained despite the shrinkage that occurs during the processes.
Solution Approach 2:
The patent implements feedback by using the measured or predicted shrinkage amounts of the fabric to adjust the data. The shrinkage correction values are determined based on feedback information about the fabric's actual shrinkage behavior, allowing the system to compensate for the shrinkage effect and maintain accurate positional relationships between the embroidered pattern and printed image.
2Manufacturing precision
If shrinkage correction is applied to maintain positional relationship, then positioning accuracy is improved, but processing time and complexity increase
Solution Approach 1:
The patent applies parameter changes by modifying the coordinate parameters of the embroidery data and print data based on calculated shrinkage correction values. The data correction unit adjusts the x and y coordinates of embroidery points and print regions according to the shrinkage amounts, transforming the original coordinate system to account for the fabric shrinkage and maintain accurate alignment.
3Productivity
If no data correction is performed, then the process is fast and simple, but the printed image displaces from the embroidered pattern on fabric
Solution Approach 1:
The system performs preliminary data correction by calculating shrinkage correction values and applying them to the embroidery and print data before the actual fabrication processes. This preliminary adjustment ensures that when the fabric undergoes shrinkage during embroidery, the printed image and embroidered pattern remain properly aligned, maintaining reliability without slowing down the actual production process.

AI summary
There is provided a data processing device, which includes a data providing unit that provides print data and embroidery data to be subjected to printing and embroidering, respectively. A print region of the print data and an embroidery region of the embroidery data have a predetermined positional relationship. The data processing device further includes a data correction unit that corrects at least one of the embroidery data and the print data so that the predetermined positional relationship between the embroidery region defined in the embroidery data and the print region defined in the print data is maintained on fabric after the embroidering in accordance with the embroidery data and the printing in accordance with the print data are performed on the fabric, considering shrinkage of the fabric caused by the embroidering in accordance with the embroidery data.
