Abstract
Techniques for correcting the color uniformity of a laser printer of a digital press or other device are provided. A process for correcting the color uniformity of a laser printer may include scanning a test page by an inline scanner of a digital press, determining scanner signal data from the test page, determining a scanner polynomial fitted to the scanner signal data, and determining a non-uniform coverage polynomial from the scanner polynomial. Additionally, techniques for verifying the linearity of a scanner are also provided.
