Updating an image quality metric database to account for printer drift |
摘要 |
What is disclosed is a novel system and method for determining a printer metric in terms of image quality (IQ) over a large complex set of conditions based upon measurements taken over a small simple set of conditions while compensating for printer drift. The present system and method effectively utilizes a predictive model that predicts noise measurements of multi-separations from those of single-separation colors and/or a subset of the multi-separations. Because a model is used to comprehend the metric over the entire gamut, the number of patches is reduced. This reduction enables the method to be used within a machine to dynamically characterize the device's image quality metric. Various embodiments have been disclosed. |
