Abstract
A hand-held printer includes an image processing module configured to process image data, an image sensor configured to provide an indicator representative of a print medium to the image processing module, a print module configured to receive the processed image data and the indicator and generate a corrected print job, and a print head in communication with the print module such that the print head is configured to receive the corrected print job and dispense a color neutral printing substance in response thereto.
Claims20
A hand-held printer comprising:
- an image processing module configured to process image data;
- an image sensor configured to provide a color indicator representative of one or more color characteristics of a print medium to the image processing module and configured to provide data indicative of a deposited image;
- a print module configured to receive the processed image data, the data indicative of the deposited image, and the color indicator and to generate a corrected print job as a function of the color indicator and the data indicative of the deposited image;
- and
- a print head in communication with the print module, wherein the print head is configured to receive the corrected print job and dispense at least a color neutral printing substance in response thereto.
A method for dispensing a printing substance utilizing a hand-held printer, the method comprising:
- processing image data representative of an image to be printed;
- dispensing at least one color printing substance on a print medium as a deposited image including a portion of the data representative of the image to be printed;
- detecting the deposited image and the print medium with an optical image sensor;
- evaluating a color characteristic of the print medium upon which the image data is to be printed;
- generating a corrected print job as a function of the image data, the deposited image, and the evaluated color characteristic of the print medium;
- and
- dispensing at least a color neutral printing substance on the evaluated print medium to create a representation of the corrected print job.
A method for dispensing a printing substance utilizing a hand-held printer, the method comprising:
- processing image data representative of an image to be printed;
- detecting a color characteristic of a print medium upon which the image data is to be printed;
- dispensing a color neutral printing substance in response to the color characteristic of the print medium, wherein the dispensed color neutral printing substance defines a color neutral print area on the print medium;
- detecting a position of the hand-held printer;
- generating a print job as a function of the image data, the position of the hand-held printer, and the color characteristic of the print medium;
- and
- dispensing a plurality of printing substances from the hand-held printer in accordance with the print job, wherein the dispensed plurality of printing substances represents the image data.
