Abstract:
A target and a method to use the target to determine the translucence of media is disclosed. The target has a first region and a second region. The first region comprises a color chart. The second region comprises a test pattern that is covered by the sample media when the sample media is loaded onto the target. The test target has a first area and a second area. An image of the target loaded with the sample media is used to determine the translucence of the sample media. The color of the media over the first and second areas of the test target are matched to the nearest color patches in the image of the color chart. The estimated actual colors of the media over the first and second areas of the test target are determined using the known colors of the nearest color patches. The translucence is determined using the difference between the estimated actual colors of the media over the first and second areas of the test target.
