| 中文摘要: |
| 网点形状是影响印刷图像复制质量的因素之一，在一定的实验条件下，将标准彩色图像数据N1～N8作为测试图像，进行了圆形、椭圆形、方形、方圆形网点的输出。对图像的阶调层次、清晰度、色彩、灰平衡等进行了主观评价，统计并分析了评价结果。实验表明：圆形网点在高调层次、清晰度、色彩方面的复制效果最好；椭圆形及方圆形网点在中暗调层次复制方面表现最好。 |
| 英文摘要: |
| Dot shape is one of the main factors influencing image reproducing quality. Under certain experimental condition, with the testing images of standard color image data N1～N8, dot shapes of square, square-and-round, round and ellipse were adopted in output processing. Image quality elements of tonal level, sharpness, color and gray balance were evaluated subjectively and grading results were also counted and analyzed. The experimental results showed that round is the best dot shape for highlight, sharpness, and color reproduction; shape of ellipse, square-and-round are optimum for middle and shadow tone images. |
