Portable spectrodensitometer FD-7

Many industries that rely heavily on graphics have been shifting to digital methods during recent time. Controlling the quality of printed materials numerically is easier and more efficient than visual evaluation. However, printed products are made to be seen by the human eye. To that end, measurement results must resemble results that would be obtained through visual evaluation. A common obstacle during print quality assessment is the paper that is used. Often printing paper contains fluorescent whitening agents (FWA) to make the paper appear brighter. The addition of these agents has an immense impact on the color of printed material, especially when the illuminate D50*1 is used for viewing. In order to lessen measurement result inconsistencies due to paper fluorescence, ISO 13655-2009*2 defined measurement condition M1 as having illumination corresponding to CIE Illuminant D50. However, conventional handheld spectrodensitometers have a hard time measuring this effect. Konica Minolta has raised the bar yet again by creating VFS (virtual fluorescence standard) technology. The FD series allows users to evaluate color while controlling for paper fluorescence. The FD series accomplishes this under illuminant D50, the standard light source measure currently used by the printing industry for color evaluation. These are the first tools to ever be manufactured that allow for measurement results that correspond with ISO 13655 Measurement Condition M1. *1 A CIE defined artificial light source consisting of a spectral distribution that simulates daylight. This is commonly used for color measurement.
