【摘要】 本文根据喷墨打印时产生的毛细管、羽化、渗透和渗色现象 ,通过统计打印点面积的扩散比、边缘粗糙度和圆度偏差 ,定义了喷墨打印质量指数IPQI。以此为依据设计出一套检测系统来评定普通喷墨打印纸的打印质量。实验对六种不同品牌的普通喷墨打印纸进行了检测 ,对他们的打印效果进行了比较。实验表明该系统能定量、客观地评定普通喷墨打印纸的打印质量。更多还原

【Abstract】 An automatic measuring system designed for evaluating the print quality of uncoated ink-jet paper is presented. Based on the degree of wicking, feathering, strike-through and color-to-color bleeding, Ink-jet Print Quality Index (IPQI), which was calculated with Area Spread Ratio (ASR), Edge Raggedness (ER), and Roundness Deviation (RD) of the printed dots, was used to evaluate the print quality. Six kinds of uncoated ink-jet papers were tested with a constant ink and ink-jet printer, the printing performances of each kind of the papers were compared. It was shown that the system could provide an objective and quantitative method for evaluating the print quality for uncoated ink-jet paper.更多还原
