Color Management

The new TECHKON DENS unifies three devices in one. It is a color reflection densitometer for CMYK color prints, a film transmission densitometer and a high-precision illuminated magnifying glass for the visual control of printing results.

This cost effective entry-level instrument allows everyone to perform a fundamental densitometric quality control on the basis of the reliable high accuracy well-known from all TECHKON instruments.

The DENS indicates densities, dot area and gray balance clearly legible on a large color display. Automatic color and gray balance detection speeds up the measuring. In addition the device is easily operated by only three buttons. The whole measurement is provided in a split of a second.

LED technology, durable and energy-saving, is used as light source. A multi-channel color sensor evaluates the measuring signal guaranteeing inter-instrument agreement with high-class spectrophotometers.

The integrated Li-Ion battery can be recharged very fast via the USB cable on any USB port and delivers energy for a few thousand measurements.

To meet the demands of a printing rooms harsh environment, the compact casing of the DENS is made of solid aluminum and is therefore very robust. Despite its solidity, the DENS nevertheless weights only 330 g and thanks to its ergonomic and elegant design it is more than a user-friendly and precise measurement tool – it is an eye-catcher.

SpectroDens is your all-purpose, modern measurement device for every application from pre-press to print. 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, no matter which application.

It combines the qualities of a highly accurate spectophotometer 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 data is converted into measurement data for descriptive analysis and display.

The device works strictly according to the standards valid for the Graphic Industry. It is particularly good at evaluating the Ugra/FOGRA-media wedge because it toggles between colorimetric measurement without polarization filter and density measurement with filter at the push of a button.

The supplied Windows-software TECHKON SpectroConnect provides the connection between SpectroDens and the PC via the micro-USB connector or via the optionally available WLAN module. Measurement data can thus be comfortably viewed and processed on the PC.

The new TECHKON SpectroDrive, with its automatic color and density measurement capabilities is the perfect solution to substantially increase press productivity by ensuring consistent print-to-print color accuracy throughout the press run.

The system consists of two components: The motorized measurement system scans the complete color bar on a printed sheet within seconds and simultaneously sends the spectral measurement data wirelessly to the PC where all relevant information for controlling the printing press is displayed. One unique feature of SpectroDrive is its flexibility to be used with any press type or format. TECHKON SpectroDrive is delivered as a complete turn-key system. 

SpectroDrive can be used as a scanning device as well as a hand-held instrument for single measurements. Just take the device from the horizontal track and position it wherever you want to take a color measurement. SpectroDrive now also features an integrated display that shows the measurement values of spot measurements directly at the device. 

The Windows-software TECHKON ExPresso 4 offers a comprehensive tool-set comprising measurement of CMYK and spot colors, support of up to 16 print units, face and reverse printing, display of color density, dot gain, gray balance, L*a*b*-values and recommendations on how to adjust the ink on the press. This is only an excerpt of the complete functionality. Thanks to its modularity, TECHKON ExPresso is expandable and versatile. The measurement data can be exported into other software applications that connect real-time to printing presses to enable a “closed loop” turn-key solution.

 

The measurement of the right dot transfer on offset printing plates is a key segment of comprehensive process control in the printing industry. At the present, plate measurement technology based on microscopic image capture and processing is the established norm. TECHKON SpectroPlate unifies all advantages of this modern measurement technology in a compact, hand-held instrument.

The extraordinary high measurement accuracy of SpectroPlate is determined by the quality of the optical system and the performance of the image processing algorithms. Thanks to the excellent image capture quality and the ingenious graphic calculations, SpectroPlate can read precisely any screen size and screen technology: FM, AM or Hybrid screen. The spectrally white illumination and dynamic color evaluation permits reading all kinds of plate types and coated surfaces.

The supplied Windows software connects the device to a PC. Measured values and transfer curves are displayed and stored. All measurement data can be used directly for linearizing a RIP powered plate processor. An exceptional feature is the enlarged view of the microscopic images.

The maintenance free measurement device is shipped with extensive accessories. SpectroPlate is available in two different types of performance packages: The entry-level model Start is for dot percentage measurements on all popular types of printing plates,film and CMYK print. The Expert-version additionally features the recording of complete transfer curves and the possibility to analyze geometric objects within the device. The Start-version can easily be upgraded to the Expert-model by a post-purchase upload from the PC.

All devices are factory-calibrated to the official reference fogra Measuring Bar FMB resulting in high long-term absolute accuracy and an excellent inter-instrument agreement. Additionally, time-consuming calibration procedures prior to measurements are obsolete.
