FD-5 Spectrodensitometer

Provides accurate evaluation, even on substrates with fluorescent whitening agents
As digital methods are increasingly used in graphics-related industries, there is a growing reliance on numerical control of the quality of printed materials, being both easier and faster than the visual evaluation the human eye can manage. However, since ultimately the final materials are intended to be seen by the human eye, the final measurement results must closely resemble the human eye results of visual evaluation.

The fact that the paper on which materials are printed influences the final viewed color is a potential problem. Fluorescent whitening agents (FWAs) are contained in many kinds of paper used for printing to give paper a brighter appearance, which can have a particularly large effect on the color of the printed materials when they’re viewed under Illuminant D50*1. For that 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. This effect was very difficult to measure with conventional, previously available, handheld spectrodensitometers.

By utilizing Konica Minolta’s original VFS (Virtual Fluorescence Standard) technology, the FD-5 Spectrodensitometer offers unique solutions to this problem, enabling color evaluation while taking into consideration the fluorescence of the paper under Illuminant D50, the printing industry’s standard light source used for color evaluation. These instruments are the first to provide measurement results corresponding to ISO 13655 Measurement Condition M1.

FD-5 Spectrodensitometer

For Measuring Color and Density

Uniquely corresponds to Measurement Condition M1 of ISO 13655

  • The first M1 type in the world.
  • Konica Minolta’s original VFS (Virtual Fluorescence Standard) technology enables L*a*b* measurements corresponding to ISO 13655 Measurement Condition M1 (CIE Illuminant D50).

In addition, color measurements can also be taken which correspond to ISO 13655 Measurement Conditions M0 (CIE Illuminant A) and M2 (illumination with UV-cut filter).

Automatic wavelength compensation function is industry’s first

  • Without requiring additional work, wavelength compensation is performed during white calibration.
  • Wavelength compensation could only be carried out as one part of manufacturer servicing until now.

Now whenever white calibration is done, this task is performed, helping to maintain the measurement values until the next periodic servicing with high reliability.

Enables color measurements that correspond with visual evaluation more closely.

  • With the new FD-7/FD-5, measurement results correspond more closely to visual evaluation results, including the effects of any fluorescent whitening agents (FWA) in the paper, whereas previously, using conventional instruments to measure materials printed on substrates containing FWA, large differences could occur between the results of measurements and visual evaluation.

Simple operation

  • Measurements of density, dot gain, dot area ratio, illumination, and color, are very simple.
  • Anyone can take measurements easily with the instructions in the LCD screen guide operation.

World’s lightest*1

With weight only about 350g for the main body, and only 430g even with the target mask attached, its lighter than any previous spectrodensitometer. The load on the user’s arm during work is reduced, improving efficiency especially when when the user is spends a long time taking measurements.

*1 As of November 1, 2010, display-equipped spectrodensitometer.

Worry-free after-sales service

  • Rapid support when needed provided by worldwide service centers.
  • Your instrument is always in top shape, ensured by a comprehensive service network is in place.

Printing Color Management Software BasICColor catch all (Optional accessory)

  • Screen can be easily customized with pass/fail screen, data list view, 3D graph, etc.
  • Various test charts are compatible (MediaWedge, ECI2002, IT8.7/3, etc.)
