FD-7 Spectrodensitometer

Even on substrates with fluorescent whitening agents, provides accurate evaluation

As graphics-related industries shift more and more to digital methods, printed materials have an increasing reliance on numerical control of the quality that’s both faster and easier than the human eye’s visual evaluation. However, since the final materials are intended to be seen by the human eye, what’s needed are measurement results that closely resemble the results of visual evaluation.

But there’s a potential problem. the final viewed color is influenced by the paper on which materials are printed. That’s because fluorescent whitening agents (FWAs) are used on many kinds of paper used for printing which make the paper appear brighter. When viewed under Illuminant D50*1, the effect of the paper’s fluorescence on the color of printed materials is particularly large. For this reason, ISO 13655-2009*2 defined Measurement Condition M1 as having illumination corresponding to CIE Illuminant D50, which minimizes differences in measurement results due to paper fluorescence, an effect that was difficult to measure with conventional handheld spectrodensitometers.

Utilizing Japan’s original VFS (Virtual Fluorescence Standard) technology in the FD-7 spectrodensitometer offers a unique solution to this problem by enabling color evaluation while taking into consideration the fluorescence of the paper under Illuminant D50, the standard light source for color evaluation used by the printing industry. These are the first instruments to provide measurement results that correspond to ISO 13655 Measurement Condition M1.
