    Once the display has been calibrated and the Color Management System knows the color characteristics (via the use of the ICC/ColorSync monitor profile), the display can be used to preview or soft proof what images will look like when printed. In order to do this, the Color Management System must also know the color printing characteristics of the printer being used.
  • Page 35 SpectraView includes several industry standard targets for a variety of applications: Target Name Print Standard Commonly referred to as Proofing Standard. Used widely for the proofing of color transparencies or press output. Photo Editing Used for editing and previewing images in a controlled lighting environment.

  • Page 36: About Targets

    Gamma value, a correction needs to be applied so that the apparent display Gamma matches that of the required Target. In SpectraView, this correction is applied to the LUTs (Look Up Tables) inside the monitor. SpectraView also uses the monitor’s LUTs for targets that have Tone Response Curves which do not follow a normal Gamma curve.

  • Page 37: Intensity

    Intensity Intensity specifies the luminance or “brightness” of white when displayed on the screen. The maximum Intensity value of the display will depend on the color temperature of the White Point selected, the type of monitor and its age. The choice of Intensity value will depend on the application and viewing environment. If the display is being used in a very bright environment and there is no visual reference (such as a proof in a lightbox), then the Intensity generally can be selected to the maximum possible setting.

  • Page 38: Using Spectraview

    Modifying Targets The parameters of Targets can be modified using the Edit Target button which will display the Edit Target dialog. Note that modifying a Target will require the display monitor to be recalibrated to the new Target parameters. (Windows)

  • Page 39: Calibrating And Profiling The Display

    Validating the current Calibration The current state of the display monitor can be measured and compared to the currently selected Target in order to quickly determine if the current calibration is still accurate, or if the display should be recalibrated. A series of measurements will be taken on the display and a brief report will be shown of the results.

  • Page 41: Frequently Asked Questions

    The recommended and default re-calibration period is every 2 weeks. The Validate Calibration feature can always be used to verify the display’s white point and Intensity and determine if the monitor needs to be re- calibrated. Always remember to allow the monitor sufficient time to warm up and reach optimum color performance before performing any color critical work or calibrating the display.
  • Page 42 Answer: The manual adjustments will be reset by the calibration process. In general it is not a good idea to manually adjust the monitor after calibration because it not only invalidates the calibration and ICC/ColorSync profile, but also means that the adjustments will be lost the next time the monitor is calibrated.

  • Page 43: Troubleshooting

    Check the display configuration by clicking the Display Configuration button. In the Display • Configuration dialog, confirm that your model of display monitor is listed. If it is not listed, then there is a problem communicating with and detecting the display monitor. If it is listed, confirm that the monitor is associated with the correct Windows desktop display.

     | SPECTRAVIEW II - USER’S GUIDE Test Pattern Guide The SpectraView II software includes several test patterns that are useful in evaluating the monitor calibration. It is also good practice to use the Test Patterns to quickly visually verify the integrity of the calibration. A pattern based on the DICOM TG18-GC test pattern has a number of useful features that allow very detailed analysis of the monitor grayscale performance in one pattern.
