OBA Detection

The OBA detection helps you to choose the right measuring condition for your characterization depending on the optical brightener agents (OBA) level of the used media and recommends a corresponding proof media type. OBA Usage is automatically detected when measuring the paper tint with a measuring device that supports to measure M1 (or M0) and M2 measurement conditions, i. e. with and without UV.

You can use the OBA detection only during the Measurement step. Once you have finished the measurement and created a characterization, this functionality is no longer available.

Starting the OBA detection.

You can start the detection from the Measurement page. Please make sure that you are using a measuring device that supports M1 (or M0) and M2 measurement conditions and that these measurement conditions have been selected (1) before starting the measurement. On the Tools & Actions panel, click Media OBA Evaluation (2) to open the window.

If you are using a measuring device that supports M0 and M2, but not M1, GMG OpenColor will calculate the M1 measurement condition from the M0 measurement.

Comparing the M1 measurements with UV (blue line) and M2 without UV (red line) shows the impact of OBA usage on the paper tint. GMG OpenColor will classify the OBA usage as either faint, low, moderate, or high and recommend a suitable proof media to ensure the highest possible color accuracy and visual match.
