| 中文摘要: |
| 各单色通道保持线性输出是喷墨打印机线性化校正的前提，以LSM（最小二乘法）的不足为启示，分析了LSM分段拟合技术的原理及特点，进而提出了针对图像的不同色调采用LSM分段拟合技术。实验分别采用LSM分段拟合技术和普通LSM拟合技术，拟合了喷墨打印机的反补偿曲线，再打印出反馈的应输入控制信息，最终评价比较了2种曲线模型下的输出样稿效果。结果表明：最小二乘法分段曲线拟合技术比普通最小二乘拟合技术更适用于喷墨输出反馈控制过程中。 |

| Precise inking of every channel is the presupposition of inkjet printers' linearization. The principle and feature of LSM piece wise curve-fitting technology was analyzed. Pictures' different tones were treated with LSM piece wise Printing feedback controlling curve was fitted with LSM piece wise curve-fitting technology and common LSM curve-fitting technology. Sample sheets printed by the two control technologies were evaluated and compared. The results showed that LSM Piece Wise method is more suitable for the inkjet printers' feedback control. |
