| 摘要: |
| 通过更改主曝光能量和时间,测试了传统印版和数码印版的高光网点面积覆盖率。 根据测得的数据,分别从相同曝光能量不同曝光时间以及相同曝光时间不同曝光能量角度,分析和评估了 2 类版材的高光网点对曝光时间及能量的敏感性。 分析发现,传统印版主曝光时应同时关注能量及时间的变化,数码印版则更加偏重于能量的变化。 |

| Abstract: |
| Area coverage of highlight dots by traditional plates and digital plates was measured by changing the main exposure energy and time in plate making. The sensibility of the two kinds of plate to main exposure energy and exposure time was analyzed and evaluated based on the measured data. It was found that the main exposure condition of traditional plate is based on both exposure energy and exposure time, while the main exposure condition of digital plate put more emphasis on the exposure energy. |
| Key words: flexographic plate main exposure highlight dot exposure energy exposure time |
