Techkon SpectroDens

A measurement device for all applications

Colorimetry

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-print for verifying proofs, for ongoing quality control at the printing press, during delivery inspection of paper and print products or in a color 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 color information - the spectral fingerprint of the color - is precisely registered. The measured spectral data is converted into measurement data for descriptive analysis and display:

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 tech- nology calculates not only density values for CMYK, but also exact data for the density of spot colors.

All standard colorimetric functions are displayed clearly. Even the entire L*a*b*- color circle appears in the display. Refe- rence colors and complete digital color books can be saved in the color library.

Standardized 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 polarization 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 color library is especial- ly easy to use. For example, you can load complete „digital color 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 colorimetric quality control.

SpectroDens | Spectro-Densitometer FAQ'S

Is SpectroDens a densitometer or a spectrophotometer?

Both. Measurement is spectral. The spectral data is converted into density or colorimetric information. The spectral measurement technology calculates not only density values for CMYK, but also exact data for the density of spot colors.

Are there different versions available?

Yes, there are three different performance packages: The Basic model with essential density functions, the Advanced version with extended density functions and colorimetry and the "all-options" flagship the Premium device.

Can the units be upgraded?

Yes, very easy via program upload with the USB connection to a PC.

Which TECHKON products are replaced by SpectroDens?

The former R410 and R410e devices are in functionality comparable to SpectroDens Basic. SpectroDens Advanced replaces the SD 620 and SpectroDens Premium the SP 820 and SP 830 products.

What is included in the package?

The measurement device, charging console with integrated white standard, device case, USB-cable, CD with software SpectroDens Connect, manual with ISO 9000 certificate.

Which system requirements does the software SpectroDens Connect have?

Microsoft Windows 2000 or XP and an USB-port for connecting the device.
