| 中文摘要: |
| 以传统印刷质量检测与控制理论为基础，结合数字印刷技术特点，提出了基于CCD机器视觉技术的喷墨数字印刷质量检测与闭环控制系统及方法，采用色度颜色偏差理论与方法，分别从色差、灰平衡、网点扩大、均匀性及色域范围5个方面，对实验和数据进行了对比分析。结果表明，修正后的颜色偏差波动水平快速达到了目标状态，补偿后的印刷质量要明显优于未控制前，验证了系统方法的可行性和有效性，为高精度喷墨数字印刷质量自动在线检测与控制提供了解决方案。 |
| 英文摘要: |
| Combined with the technique characteristics of ink-jet digital printing, a quality detection method based on traditional printing quality detection theory and CCD machine vision technology and closed loop color control system was designed. Based on chromaticity deviation theory and method, the grey balance, dot enlargement and uniformity was discussed through the experiment and data analysis. The result showed that the revised color deviation fluctuation quickly reaches to the target state level; the effect after compensation is much better than before. This method is proved to be more effective for high-accuracy automatic on-line detection and control of ink-jet digital printing quality. |
