Gray Balance

Gray balance is an optional step that determines the output levels of each color needed in order to produce a neutral gray for color and grayscale images.

1. Calibrate your measurement device:
   1. Select the type of measuring device and the port that connects it to your computer.

      Not all devices support calibration from Color Profiler. If the Calibrate button is disabled, you should calibrate your device using the software provided with it before using it with Color Profiler.

   2. If desired, click Settings to set advanced settings for either type of device:

      Illuminant	The light source currently used by the device.
      Observer	The observer angle.
      Status	The status currently used by your colorimeter. If you are unsure which status to use, we recommend using Status A (Automatic). This status will be uniform across all colorimeters.
      Samples	The number of samples that will be taken of each swatch in a test pattern for automated measuring devices.
      Spacing	The amount of spacing between the samples, expressed as a percentage of the width of the swatch. This field is disabled when only 1 sample is specified. The approximate position of the specified samples is displayed in the square below.

      Not all settings are available for all devices.

   3. Click Calibrate and follow the on-screen instructions.
2. Do one of the following:
   • Import measurement data from another ICC Profile by clicking Import.

     The color modes of the current ICC Profile and any imported measurement data must match.

   • Print a reference to determine if gray balance is necessary by clicking Print Reference.
3. Determine whether gray balance is necessary:
   • If the reference swatches seem neutral and do not look like they contain too much of any one color, click Next.
   • If the reference swatches look like they contain too much of any one color, click Print Target.
     1. Click the Measure button to measure the swatches with your measuring device.

        After you measure the swatches, check to see that the measured swatches line up with the target swatches.

        

        If you need to remeasure swatches:

        • To remeasure the entire target, click the Measure button.
        • To remeasure a swatch sheet, select a swatch and click the Remeasure one sheet button.
        • To remeasure a swatch strip, select a swatch in the strip that you want to remeasure and click the Remeasure one strip button.
        • To remeasure a single swatch, select the swatch and click Remeasure one swatch button.

          Depending on the type of measurement device you use, the choices for remeasuring may be limited.

     2. Once you finish measuring, click Print Verification to print verification swatches and see if there is an improvement in the gray balance.
4. If you see an improvement in the gray balance, click Next.

   If you see no improvement in the gray balance, check Ignore Gray Balance and click Next.
