We are proud to offer the world’s only handheld instruments that can measure both density and colour of printed matter for any illuminant even if the substrate contains fluorescent whitening agents (FWA):
The Spectrodensitometers FD-7 and FD-5.

The Fluorescent Spectrodensitometers FD-7 and FD-5 are equipped with the newest technology of Konica Minolta: VFS (Virtual Fluorescence Standard). This technology enables colour evaluation taking into consideration the fluorescence of paper under any illuminant, including D50 (ISO 13655:2009 M1). The new VFS technology takes advantage of the optical, sensor and software technology cultivated through our long experience with colour-measuring instruments to enable virtual measurements for a variety of illuminants while including the influence of fluorescence.


The optional long ruler for the Konica Minolta FD-7 allows to conduct scan-measurements of strips with a length of up to 50cm.

basICColor Catch QC and the „Konica Minolta FD-7 OneScan PSO Check“ control strip enable users to conduct a complete PSO certification in seconds.

The FD-7 is the perfect tool to help printers in their daily business. The lightweight FD-7 makes all colour related tasks in the printing industry easier and more reliable.

TARGETMATCH including backing conversion helps printers to achieve the right colour on their production paper.

ISOCHECK enables fast quality control without additional software.

The possibility to measure printing plates can make the additional investment in a plate measurement device obsolete.

DeltaBrightness gives unambigous information about the amount of optical brightener and allows a fast control of production papers.

The scan measurement functionality allows fast measurements of control strips and profiling charts. With the optional long ruler a complete print QC is conducted within seconds.

The Spectrophotometers FD-5 and FD-7 were the world’s first M1-type instruments, utilizing Konica Minolta’s original VFS (Virtual Fluorescence Standard) to provide measurements corresponding to D50. Konica Minolta’s VFS makes the FDs the only instruments that can measure FWAs for any chosen illuminant, including self-measured illuminants.

With spectrophotometers, white calibration is performed as part of the daily work, and this calibrates the spectral reflectance coefficients (vertical axis). The FD-7 and FD-5 are equipped with the industry’s first “Automatic Wavelength Compensation” function which automatically calibrate in the wavelength direction (horizontal axis) when white calibration is performed as part of daily work, greatly improving the reliability of measurement values.

In addition to spot measurements, manually scanned measurements are also possible when the FD-7 is connected to a PC. The versatile colour measurement software Catch is shipped with every FD-7. A ruler for precise guiding the instrument on the colour patches is included as standard accessory of the FD-7. A long ruler enabling measurements of strips with a length of up to 50 cm is available as optional accessory.

With the FD-7 the spectral power distribution of the illumination environment under which visual evaluation is performed can be measured. The measured data can be used to get a close correlation between the numerical data and the visual judgment.
