A measurement device for all applications
Using measurement technology for quality assurance in print is a universally accepted practice these days. SpectroDens is your all-purpose, modern measurement device. Whether it be in pre-press for verifying proofs, for ongoing quality control at the printing press, during delivery inspection of paper and print products or in a colour lab, SpectroDens is exceptionally suitable, whatever your application. Thanks to the individually adjustable display functions, you can quickly set up the device for your particular job.
Two devices in one
The product name alone suggests the multiple uses of the device. As a spectro-densitometer, SpectroDens combines the qualities of a highly accurate spectro-photometer and an easy to- use densitometer. Measurement is spectral, i.e. the entire colour information – the spectral fingerprint of the colour – is precisely registered. The measured spectral data is converted into measurement data for descriptive analysis and display:
• Densitometric data is widely used in quality control during the printing process.
• Colourimetric data is used in the evaluation of printproofs, the creation of colour profiles in colour management and the colour matching and formulation of inks.
Densitometry
A push of a button provides you with solid density as well as all useful additional information such as dot gain, dot area, gray balance and print contrast. In the automatic measurement mode the device always displays the relevant information instantly. You can even quickly and easily produce complete characteristic printing curves. The spectral measurement technology calculates not only density values for CMYK, but also exact data for the density of spot colours.
Colourimetry
All standard colourimetric functions are displayed clearly. Even the entire L*a*b*- colour circle appears in the display. Reference colours and complete digital colour books can be saved in the colour library.
Standardised measurement
The device works strictly according to the standards valid for the graphic industry. Select different status filters for density measurement among the device settings. A special technical feature is the polarisation filter which can be activated via the push of a button.
Comprehensive software
Connect the measurement device via USB-cable to a PC. The SpectroDens Connect software supplied with the device explicitly displays measurement data on a computer monitor. Measurement data can be transferred into Microsoft Excel or other applications. The integrated colour library is especially easy to use. For example, you can load complete “digital colour books” into the device. The software also serves as the connecting module for other applications, e.g. programs for the production of characteristic printing curves or colourimetric quality control.
Functions
We supply SpectroDens in three types of performance packages: The model Basic with the essential density functions, the Advanced version which adds extended densitometry functions, colourimetry and a colour library and as the flagship model the comprehensivePremium device. You can upgrade the devices post-purchase to higher performance levels by program upload.
