摘要:
Screened hardcopy reproduction apparatus for applying toner to a receiver using a print engine that may not apply toner uniformly, so the toner applied to the receiver has a non-uniformity. A controller receives an input pixel level and a corresponding input pixel location; a tone-reproduction unit calculates an output pixel level from the input pixel level and a corresponding output pixel location from the input pixel location; a compensator calculates a compensated pixel level from the output pixel level and the output pixel location; and a screening unit calculates a screened pixel level and a screened pixel location from the compensated pixel level, the output pixel location, and a selected screening pattern. The print engine applies an amount of the toner corresponding to the screened pixel level and the non-uniformity to the receiver at a toner location corresponding to the screened pixel location to compensate for the non-uniformity.
