At present, plate measurement devices based on microscopic image capture and processing are the established standard with accuracy determined by the quality of the optical system and the performance of the image processing algorithms.
Techkon’s SpectroPlate uniformly illuminates each sample with spectral broadband light. The microscopic image is captured by a precision optical lens system and a high resolution CMOS color matrix sensor with high dynamic range.
The processing of the detailed color image is performed by a powerful graphic signal processor and sophisticated imaging algorithms. All relevant quality parameters for correctly manufactured printing plates are shown on the LCD display.
The excellent image capture quality and the graphic calculations, means SpectroPlate can read precicely 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.
SpectroPlate is multifunctional device, handling dot measurement on film as well as on printed paper in CMYK-print. It can also be used as a portable microscope. A specific strength is the image transfer of uncompressed high-resolution files to the PC where they can be stored, edited or sent over the internet. Geometric sizes of dots or lines can be retrieved in micrometer- or mils-dimensions.
The supplied Windows software SpectroPlate Connect links the device to a Windows PC. Measured values and transfer curves are diplayed and stored. The display of comparisons to
target values, the data export to Microsoft Excel and the compatibility to RIP-applications are additional useful functions of SpectroPlate Connect. An exceptional feature is the enlarged view of the mircoscopic images.
The maintenance-free measurement device is designed to work in harsh industrial environments.
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.
TECHKON GmbH, located in Königstein near Francfort, Germany, is a leading manufacturer of densitometers, spectrophotometers and software solutions for the graphic arts industry.
