精品印刷品的质量的三种判断方法
作者:admin 来源:http://www.sdhzyw.com 发布时间:2016-6-28 17:33:24 浏览次数:320
主观目测法
Subjective visual method
这是一种比较直观,简单的办法,也可以说是一种对比法,将产品与标准的产品进行对比,好与坏就比较简单能判断出来,但是我们在对印刷品的质量判断的时候,还是有很多的客观印刷无法掌控。同时也就影响了产品的正确判断。
This is a more intuitive and simple way, it can be said is a comparative method, comparing the standard products and products, good and bad is relatively simple to judge, but we in the printing quality judgment, there are still many objective printing no control. At the same time, it also affects the correct judgment of the product.
密度检测法
Density detection method
密度测量,这是一种比较专业的办法,原理就是反射或透射光量的量度,是同一种油墨饱和度的相对值的反映。这个办法是需要借助仪器来完成的,不过放心,这种仪器很便宜,使用的人很多。但是也是有缺点的,那就是只能获得印刷中某一原色油墨的相对量,而不能指示被测颜色的色相,不能与表色系统联系,对颜色作出描述,其使用有一定的限制性。
Density measurement, which is a more professional approach and measure principle is reflected or transmitted light, is to reflect the relative value of the same ink saturation. This approach is to use the instrument to complete, but rest assured that this instrument is very cheap, the use of a lot of people. But also has shortcoming, that is the only access to the relative amount of printing a color ink, and no indication of the measured color hue, not with the surface color system, the color make the description, the use of certain limitations.
色度检测法
Colorimetric detection method
这是一种更为科学的检测办法,色度检测法首先确定调试范围内的光谱反射率,然后根据光谱反射率或据此推导出来的一些色度特征参数实现墨量的调节控制,测量结果与人眼的视觉感受有直接联系,可以更直观的表现出印刷的颜色情况。
This is a most scientific detection method, colorimetric detection method first determines the range of spectral reflectance of debugging and according to the implementation of spectral reflectance or accordingly derived some color characteristic parameters of the adjustment and control of the amount of ink, measurement results with respect to human visual feel is directly linked to, can be more intuitive performance of printing color.
