    The measurement accuracy of a plate measuring device is determined by the quality of the optical system and the performance of the image processing algorithms. SpectroPlate meets the highest standards in this respect. The sample is illuminated uniformly 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.

    1.4 Working with SpectroPlate Switching on and off SpectroPlate is switched on by pressing the green measurement button. It is imme- diately ready to measure. If no button is pressed within two minutes, the device will switch off automatically. Switching it on again with the green measurement button will show on the display the last measurement done.
  • Page 11 The SpectroPlate display is divided logically into a section where the measurement results are displayed and a frame of “soft keys”. Notice: In the Start-version of SpectroPlate certain “soft keys” will be not select- able and are shaded in gray. These are the functions which are only available for the Expert- and All-Vision-model.

  • Page 14 Calibration SpectroPlate is factory-side calibrated. A white calibration adjusts the digital camera module. The screen calibration is for exact adjustment of dot percentage mea- surements towards the reference plate Fogra Measuring Bar FMB. The calibration remains permanently and the devices are long-term stable. This means that there are no time intervals for re-calibration necessary.
  • Page 15 Select “Calibration” and then “White Cali- bration” from the menu “device settings” and follow the instructions on the device display. The calibration is confirmed by an acoustic signal. Manual TECHKON SpectroPlate Chapter 1 – How to use SpectroPlate Page 15...

  • Page 17 Setting the plate type SpectroPlate will carry out optimized image calculations depending on the type of offset printing plate used. Therefore the type of printing plate has to be selected. Also for measurements on film or printed paper the right setting has to be made first.

  • Page 18: Care And Maintenance

    1.5 Care and maintenance SpectroPlate is a highly-precise optical instrument. It is designed to work in harsh, industrial environments. However, it should be handled with care. Avoid mechani- cal shocks, heat, dusty or humid environments. Keep it always at a safe place, for example in the carrying case.
  • Page 19 Error handling Should SpectroPlate do not work properly, first check, if all instrument settings and measurement conditions are set correctly. Next perform a white calibration on the white standard which is integrated in the charging console and try again to perform measurements.
  • Page 20 – depending how it was used – it will loose its capacity and it will make sense to replace it. Only use original TECHKON SpectroPlate replacement batteries. The use of other batteries is hazardous ! For opening the battery case you will need a Philips screwdriver type 1.
