Chapter 1

General description of the measurement system

1.1 Product description

Accurate, fast and easy to use

SpectroJet revolutionizes automatic measurements of print quality on print control

bars, color wedges and test charts.

Color measurement made easy: The compact measurement device is quickly guided

by hand along the color bar. Tracking wheels on the bottom of the device ensure a se-

cure and straight run. At longer distances the device can be slid along a guiding track.

The measurement data is transferred simultaneously to a PC in order to control the

color quality of the printing press.

All-purpose device

Thanks to the modular concept of SpectroJet it can be used for any printing process

and quality standard. ISO 12647, PSO, Fogra media wedge, Gracol G7™ or any other

standardization method can be applied: SpectroJet will always deliver all relevant mea-

surement data necessary for evaluating high quality prints.

The supplied software TECHKON SpectroConnect displays clearly all measurement

values on the computer screen, which are transferred by SpectroJet via an USB

connection. All measurement values can be exported as well into other applications,

such as Microsoft Excel™ for example. The additionally available software TECHKON

ExPresso is especially suited for the evaluation and documentation of the print quality

according to various quality control methods, e. g. ISO 12647 or Gracol G7™.

ISO compliant measurements

By software command a physical polarizing ﬁlter can be inserted which is the pre-

condition for conforming to the print standards. Multiple functions – color densities,

colorimetry, printing contrast, gray balance, dot gain or ink setting recommendations –

SpectroJet is a versatile and valuable tool for achieving highest print quality and

boosting the productivity of a printing press.

2.1 Assembly of SpectroJet

SpectroJet is a solidly designed measurement device which is very functional and easy

to use. It is compact in size; the buttons can be reached with the right index ﬁnger

when the device is held with the right hand. The LED row is always visible.

A great advantage of SpectroJet is the fact, that it can be easily positioned on the

measurement sample.

The device incorporates a high-resolution spectral sensor which analyzes the color

spectrum of the measured sample. The spectral data is the base information for calcu-

lating densitometric and colorimetric data which is displayed. Densitometric values

can be solid density, dot area, dot gain or trapping values. Colorimetric values are

typically CIE L*a*b*- or ΔE-color information.

The USB-connector is for linking with a PC. The self-locking push-pull-connector ﬁts

into the socket at the back of the device.
