摘要: |
在保证设备性能稳定、印刷材料符合标准的情况下,使用G7方法进行了印刷标准化测试,并介绍了测试现场控制的方法,然后分别对基础测试和特性化测试的数据进行了前后对比,发现在应用中性灰平衡NPDC曲线得到的校正补偿曲线重新出版印刷时,测得的亮调范围HR、亮调反差HC、暗调反差SC值,中性灰密度值,网点扩大曲线情况均达到了G7标准,再次得到的NPDC曲线基本符合标准曲线趋势。说明基于G7方法的印刷标准化测试方法十分有效,并可为使用G7方法进行印刷标准化测试的企业提供借鉴。 |

Abstract: |
In conditions of stable performance of devices and standard materials, printing standardization test was carried out based on the G7 method. The control methods of the test location were introduced. The data of foundation and characterization tests were compared. It was found that when using adjustment compensating curve obtained from NPDC curve to publish printing plate, HR, HC, the SC value, the neutral density value, dot gain curve situation can meet G7 standard; the redone NPDC curve meet G7 standard curve trend. It was showed that printing standardization test method based on the G7 method is very effective and it can provide reference to the enterprises that use G7 method to take printing standardization test. |
