  • Page 38 80% 40% BAL 2. 3. The setting for the %-patches to be measured is done in Dot Gain Setup. Up to three percentage values can be edited. The TECHKON TCS print control strips include two different %-patches; 80 % and 40 %.
  • Page 39 SCTV The Spot Colour Tone Value (SCTV) function, which is defined in ISO 20654:2017, pro- vides a precise colorimetric quality inspection for spot colors. SpectroDens supports SCTV for single tone value measurements and the SCTV printing curve (see page 42).
  • Page 40 Typical values for standardized print with Paper Class 1 (glossy, coated) are: C+M > 60 %, M+Y > 72 % and C+Y > 85 %. SpectroDens offers extended trapping calculation according to Professor Ritz and Fe- lix Brunner, which ensure a better comparison between C+M, M+Y and C+Y measure- ments.
  • Page 41 3. Increments of the wedge to be measured, e. g. in 5 % steps In the first step a 100 %-(solid) patch is mea- sured. SpectroDens recognizes automatically the color and displays the solid density. In this case D = 1.50 for Cyan.
  • Page 42 Manual TECHKON SpectroDens Now the corresponding current dot area is indicated in the lower right section of the dis- play. In this case: + 7.3 % dot gain is displayed at 90 % dot percentage. The shaded area close to the curve shows the tolerance range.
  • Page 43 Beside energy and focus of the laser, dot gain is the most important information which has to be checked in plate exposure. Special plate measuring instruments working with video analysis have been developed for this application; for example TECHKON SpectroPlate. Compared to densitometers and colorimeters they offer big advantages.
  • Page 44 2. Now measure a dark, 100 %-imaged patch. SpectroDens will select one of the four CMYK channels where the contrast signal is highest depending on the color shade of the plate. In this case the Cyan channel gave the highest signal, because the plate is blue/violet.

    CIE L*a*b* The previously described measurement functions all were based on densitometry. Thanks to the spectral performance of SpectroDens it is possible to calculate and dis- play colorimetric values as well. Measurements in colorimetry modes have the advan- tage of an absolute description of color based on characteristic values.
  • Page 52 In colorimetry the white reference is absolute in contrary to densitometry where the white is usually referenced to paper white. Before making colorimetric measurements, an absolute white calibration has to be carried out by placing SpectroDens on the charging console and calibrating on the round, white ceramic standard.
  • Page 53 CHAPTER 2 – Measurement functions CIE Color Circle The function CIE Color Circle shows the L*a*b*-color values as well. Optionally L*C*h*- values can be displayed. Additionally there is a graphic display and a color is shown as a spot within the color circle. Select the CIE Color Circle Setup function out of the list of measurement conditions.

  • Page 68 Manual TECHKON SpectroDens Metamerism-Index Metamerism is the visual phenomenon that two colors match under certain light con- ditions and differ under different light conditions. Colorimetry offers the possibility to detect this effect by measuring the color distance between the two color samples under two exactly defined light sources. The result of this operation is the Metamerism-Index.
  • Page 69 Whiteness / Yellowness Whiteness- and Yellowness-indices are quality parameters important for the paper industry. SpectroDens Premium will display the whiteness and yellowness indices ac- cording to the following standards: Whiteness: E 313, Berger, Stensby, TP 425 – Yellow- ness: E 313, D 1925.
  • Page 70 Manual TECHKON SpectroDens Brightness T (TAPPI 452) Like whiteness, paper brightness is also a measurement of the amount of light reflected from paper. Unlike whiteness, it is focused on a narrow wavelength of blue light as opposed to all wavelengths in the spectrum. The higher the number on the brightness scale, the more light a particular sheet reflects.
  • Page 71 Just keep the green start-button pressed during the whole scanning procedure. SpectroDens recognizes the version 2 as well as the version 3 of the media wedge by the different number of reference values. The Windows software SpectroConnect allows to analyze the measured data in detail and to print a report (see p.
  • Page 72 Manual TECHKON SpectroDens Scan The measurement function Scan provides the scanning of individual control elements. The scanning procedure is very easy. Choose the measurement function SCAN in the device menu. Then place the measurement device on the print control strip.
