Measuring Colors without Test Chart

You can use GMG OpenColor to measure any color patch—directly from the print product, from a single color patch, from a print control strip, or from any patch layout. You only need a hand-held spectral photometer and information on the color separation of the tone you want to measure, i. e. which inks are printed and the tint percentage value, for example, "PANTONE 301 (80%)".

Double measurements of the same color and tint will be averaged automatically.

You will need to switch to Custom.

  1. From the Source list, select Custom.
    The Measurement Mode will be automatically switched to Patch.
  2. On the Tools & Action panel, click Start Measurement.
    The measuring device will be initiated for measuring. If manual interaction is required such as white calibration, you will be notified by a message.
  3. Follow the instructions to prepare the measurement.
    When the measuring device is ready, the Measurement status changes to Measuring... and you will be asked to measure the paper tint.
  4. Measure the paper tint: Move the measuring device to an unprinted substrate area and press the device button to measure.
    The measured paper color is shown and categorized as Media.
  5. Proceed with the color patches: Press the device button to start the measurement and measure all color patches in any order.

GMG OpenColor lists the measured patches in the order of measurement. The list is updated after each reading. Recognized colors are automatically assigned.

You will now need to assign inks and percentage values to the measurements.
