Abstract:
A system and method for printer control and color balance calibration. The system and method address the image quality problems of print engine instability, low quality of color balance and contouring from the calibration. The method includes defining combinations of colorants, such as inks or toners that will be used to print images, defining a desired response for the combinations that are to be used and, in real time, iteratively printing CMY halftone color patches, measuring the printed patches via an in situ sensor and iteratively performing color-balance calibration based on the measurements, accumulating corrections until the measurements are within a predetermined proximity of the desired response. The calibration is performed on the halftones while they are in a high quantization resolution form.
Abstract:
The invention provides a method for processing a document to be rendered in which rendering intent selection is based on input color space. In one aspect, the method includes the following steps: a) identifying an object type for an object in the document; b) identifying an input color space of the document; c) selecting a rendering intent for the document based on the object type and the input color space; and d) processing the document using the selected rendering intent. In another aspect, the method includes the following steps: a) identifying an object type for each object in the document; b) identifying an input color space of the document; c) selecting a rendering intent for each object in the document based on the object type and the input color space; and d) processing the documented using the selected rendering intent(s).
