Abstract

A system for visualizing a print job includes a print job simulator which applies a print job model to print job image data to generate an image which simulates a rendered image of the print job if the print job were to be printed on a specific marking device. The system also includes a display in communication with the print job simulator for displaying the simulation image. The modified image data displayed on the display enables a customer to see a defect in the print job which would appear if the print job were to be rendered on the specific marking device. The print job model may be derived, at least in part, from information derived from the marking device, such as information derived from image data acquired by scanning a test image which has been rendered by the marking device.

Claims

1. A printing system comprising:

at least one marking device, each of the marking devices being configured for rendering a print job on print media;

a model generator which, for each of the marking devices, generates a print job model based, at least in part, on image data acquired by scanning a test image rendered by the marking device, the specific marking device being a xerographic marking device which includes a photoreceptor; and

a print job simulator which applies at least one of the generated models to print job image data different from the test image, whereby when the print job image data to which the model has been applied is displayed on a display, a defect in the print job which would appear if the print job were to be rendered on the at least one marking device is visualized.

2. The system of claim 1, wherein the print job model is derived at least in part from a diagnostic engine which diagnoses a cause of an image defect.

3. The system of claim 1, further comprising memory in communication with the print job simulator which stores the print job model.

4. The system of claim 3, wherein the memory stores a plurality of print job models for a plurality of marking devices and wherein the print job simulator applies a model for a selected one of the marking devices.

5. The system of claim 1, wherein the print job model is updated at intervals to reflect a change in the specific marking device detected by the sensor.

6. The system of claim 1, wherein the model comprises gray level values for a single colorant or for multiple colorants which is merged with print job image data to simulate the rendered image.
