    Profiler User Manual 3.7 Validation After the calibration and profiling process SpectraView Profiler 5 is processing a detailed check. This check is a simple integrity test of the calibration and the created profile. This test was not designed to check if a display is able to be a softproof- ing display.
  • Page 27 Profiler User Manual Every calibration should be checked once a while (e.g. once a week) to check if the display calibration and the profile are achieving the param- eters which where achieved at the original calibration time. To validate the display place the measurement instrument in the middle of the measurement window and start the validation process with a click on <measure>.

    SpectraView Profiler 5 offers three different calibration methods. At first launch it will automatically select the highest level method available for your monitor/video card combination. When you quit the application, the calibration method you may have selected manually, will be stored and recalled next time you use SpectraView Profiler 5.

  • Page 38 LCD monitors with an analog connector only will yield inferior calibration quality altogether. Higher quality LCD monitors (like the NEC MultiSync family of monitors) offer 10 or more bit data processing. Only this type of monitors satisfies higher quality demands.
  • Page 39 Profiler User Manual CRT - monitors In CRTs the intensity of the 3 phosphors is controlled by an analog signal that can be modulated nearly infinitely variable. Since the inten- sity of each channel can be controlled individually (gain), the color temperature can be set very exactly.

  • Page 40: No Calibration

    Corrections for color temperature and tone curve are not available in this mode. Also, adjustment of luminance and contrast can only be done manually. SpectraView Profiler 5 supports you with measurement values in setting these parameters. Should the graphic card contain a LUT when launching SpectraView Profiler 5 it will be taken over and saved in the ICC- profile.

  • Page 41: Calibration Preset

    When selecting a calibration preset, all the necessary settings will be done automati- cally by SpectraView Profiler 5. You don’t have to select all the calibra- tion options like “Color temperature”, “Tonal response curve” etc.
  • Page 42 Profiler User Manual Webdesign - This preset will set up your monitor for a webdesign worklfow. Prepress - This preset contains the correct settings to calibrate a display to the needs of the Prepress- Workflow. Besides this preset is can be recommended to photog- raphers who wants to retouch their images for the output of an photo-lab, Fine-Art-Printers, Inkjets or other printing devices.
  • Page 43 User Manual Some of those presets are already represented by a workflow-icon in the main window of SpectraView Profiler 5. An exception is the last workflow-icon of the main window of Spectra- View Profiler 5. The default setting for it is “custom”. But this workflow- icon is a placeholder for a whole list of calibration presets.
  • Page 44 The calibration settings which are represented by workflow-icon can be seen in the middle of the main window of SpectraView Profiler 5. If the custom workflow-icon will be used to create a calibration and...

  • Page 45: Creating Custom Calibration Presets

    As mentioned in the previous section a single change on a parameter will rename the calibration preset form it’s original name to the name “custom...”. At this point SpectraView Profiler 5 gives the user the opportunity to save these new calibration settings as a custom calibration set with it’s own name.
  • Page 46 The new calbration set can be chosen from the list of calibration presets like any other predefined calibration preset. It’s possible to activate the new created calibration preset via the custom workflow-icon in the main window of SpectraView Profiler 5.

    D-series (D = Daylight). SpectraView Profiler 5 offers quite a lot of different possibilities to make „D50“ spectral distribution curve of a CRT monitor...
  • Page 48 Profiler User Manual For the graphic arts industry, D50 is the standard for viewing and comparing color. Also the color systems L*a*b* and XYZ as we use them in graphic arts, are based on this illuminant. These are the reasons why a computer monitor in an ICC- compliant working environment needs to be calibrated to D50.
  • Page 49 Profiler User Manual Blackbody temperature As described earlier, an illuminant can be characterized with its corre- lated color temperature. D50 for example has an approximate color temperature of 5000K, but the blackbody radiator has a different spectral distribution at 5000K. Monitors show a different, characteristic spectral distribution, their white point can only be approximated.

  • Page 50: Tonal Response Curve

    Profiler User Manual 4.7 Tonal response curve Shades of gray from black to white will be reproduced in a specific way, depending on the individual monitor. CRTs and LCDs are very differ- ent in their native characteristics. In order to normalize the response character monitor calibration corrects the tonal response curves to a defined function.
  • Page 51 Profiler User Manual Since ICC profiles are based on L*a*b* as well, the conversion losses are minimized when converting color to the monitor gamut. If you calibrate your monitor to L*, your RGB working space should have an L* tonal response curve also. You can download such a working space (ECI-RGB v2) from www.eci.org.
  • Page 52 Profiler User Manual The only use of a gamma calibration is a workflow with data which need to be displayed with a certain gamma or other tonal response curve (e.g. video or web design = sRGB) out- side a color managed environ- ment.

  • Page 54: Luminance / Contrast Ratio

    Profiler User Manual 4.8 Luminance / contrast ratio Here you can define parameters that are important in different ways. If you should use several monitors in your environment, it makes sense to harmonize them to the same visual appearance. These settings allow you to do so in different ways.
  • Page 55 For the visual appearance of a monitor, not only the tonal response curve and the white luminance are of importance, but also the black luminance. SpectraView Profiler 5 allows you to calibrate monitors to a defined black luminance. Here the highest black luminance is the refer- ence for harmonizing multiple monitors.

  • Page 56: Profile

    Profiler User Manual 4.9 Profile ICC-profiles can use a different internal structure for some param- eters. Two important parameters are the profile type and the chromatic adaptation. 4.9.1 Profile type The function of an ICC profile is to describe the color characteristics of your devices in a device independent color model (e.g.
  • Page 57 Profiler User Manual 16-BIT LUT-based In this profile type, the gamut of a device will be described in a table of a defined number of points. All other color values will be interpolated. This allows to describe non-linear behavior of a device. The size of a LOUT profile can be some- where between 200 KB and more than 2 MB.

  • Page 58: Chromatic Adaption

    Profiler User Manual 4.9.2 Chromatic Adaption Chromatic adaptation is the ability of the human visual system to discount the color of the illumination and to preserve the appearance of an object. Chromatic adaptation can be observed by examining a white object under different types of illumination, such as daylight (blueish) and incandescent (yellowish).
  • Page 59 Changes appear less intensive than in the „von Kries“ method. CAT02 (von CIECAM02) This is the latest development in CATs, it’s effect is close to that in the „linear Bradford“ method. SpectraView Profiler 5 uses CAT02 as a default.

  • Page 60: V4 Profile

    Profiler User Manual 4.9.3 V4 profile If you check „ICC v4 profile“ SpectraView Profiler will create ICC profiles according to the latest specification (including the correct chromatic adaptation tag). Under windows, v4 profiles do not make sense since the Windows color management system ICM is not capable of utilizing these profiles (ACE, the CMM built into Adobe products can handle v4 profiles).

  • Page 61: Review

    4.10.1 Monitor This tool allows you to check the quality of any profile and calibration, not only those created with SpectraView Profiler 5. After measuring the validation patches you see the „Validation Results“ window. The measured values are compared with the reference values calculated from the ICC profile.

SpectraView Profiler 5 communicates with the lightbooth and will automatically adjust its brightness to the monitors brightness. Please take notice that the monitors brightness should be set to a standardized value.
