是有点拗口了哦。
UV-no难道意思是：NO UV没有紫外光进入：
UV-cut就能难理解了
bonafide1978又说：UV-no是有滤镜 可为什么后面又成了filter off呢？迷糊了！

这个我以前做实验的时候测过……太麻烦了~~呵呵
数据一大堆~

这个问题越搞越复杂，有没有爱色丽公司的技术高人来解释一下呢？现在买爱色丽测量仪器的公司很多啊！

如果你是UV-no，不好意思，这里打错了，是UV-on. 后面的filter off。 这是xrite 继续了DTP70的命名系统。

另外再纠正一下，现在的isis 是用两个光源。一个权限于400-700，另外一个是低于400nm的uv 光源。前一个测量的是uv cut,两个合并是UV-on.

另外，确定地测量uv ，靠这两个光源是远远不够的。需要再购买一个munsell gray card 这样一个东西一个OBC (optical brightener compenation)的软件。

May not be related, an useful information

深有同感! 做铜版纸分别不大,做其他纸 UV CUT没用

Hello to everyone!

I just read this topic and it's very interesting but I think it's not so clear viewing it by pratical means..

I don't know if the information I will give can be usefull but I'll try! :)

I own two spectro,

1 is a UV cut X-rite I-one.
2 Is a non UV cut I-one

Using a UV-cut spectro is necessary if the support where you print the patch for linearization or calibration purpose has too much UV reflecting coat.

I also have a Wood lamp to test for paper or print support in general.

If it's shine I use a UV cut X-rite I-one

If I try to make a calibration with a non UV cut spectro with a paper that reflects too much UV light I have a color space not as big as I use the UV cut spectro..

This is because the Uv component of the light that the media reflects is red by the spectro and get a false value.. ( The spectro read an higher bightness that the real brightness)
