Brightness scale
WebTechnidyne’s TEST/Plus product is a simple ISO brightness tester tool. The values are measured to ISO brightness scale from 0-100. Higher the values, higher is the brightness of the paper. So, let’s say, if a paper has an ISO brightness of 92 while the other is 94, it is harder to differentiate between the two.
