The measurement of the right dot transfer on offset printing plates is a key segment of comprehensive process control in the printing industry. At present, plate measurement technology based on microscopic image capture and processing is the established standard. 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 mircoscopic 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 officical 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.
