Abstract
Methods and apparatuses are provided for use in printing devices. In certain implementations, ink is printed to a first area of a print medium and a second area of the print medium. The ink is applied to the first area at a higher density than the second area. A first light scattering intensity value is measured from the first area and a second light scattering intensity value is measured from the second area. The print medium is categorized based on a comparison of the light scattering intensity values.
Claims41
A method of printing with an ink jet printer, the method comprising:
- selectively applying at least one ink to a first area and a second area of a print medium, wherein said at least one ink is applied to said first area at a higher density than said second area;
- measuring a first light scattering intensity value associated with said first area and a second light scattering intensity value associated with said second area;
- and
- categorizing said print medium based on a comparison of said first light scattering intensity value and said second light scattering intensity value.
An apparatus comprising:
- a printing mechanism configurable to selectively apply at least one ink to a first area of a print medium and a second area of said print medium, in a manner such that said at least one ink is applied to said first area at a higher density than said second area;
- a sense mechanism configurable to measure a first light scattering intensity value associated with said first area and a second light scattering intensity value associated with said second area;
- and
- logic operatively coupled to said printing mechanism and said sense mechanism and configured to categorize said print medium based on a comparison of said first light scattering intensity value and said second light scattering intensity value, and based on said comparison selectively set at least one printing parameter.
A method comprising:
- selectively applying at least one ink to an area of a print medium;
- measuring a first light scattering intensity value associated with said area at a first time, and a second light scattering intensity value associated with said area at a second time subsequent to said first time;
- and
- categorizing said print medium based on a comparison of said first light scattering intensity value and said second light scattering intensity value.
A method comprising:
- selectively applying at least one ink to a first area of a print medium;
- measuring a first light scattering intensity value associated with said first area and a second light scattering intensity value associated with a second unprinted area;
- categorizing said print medium based on a comparison of said first light scattering intensity value and said second light scattering intensity value;
- and
- selectively setting at least one printing parameter based on said categorization of said print medium.
An apparatus comprising:
- means for selectively applying at least one ink to a first area of a print medium and a second area of said print medium, in a manner such that said at least one ink is applied to said first area at a higher density than said second area;
- means for measuring a first light scattering intensity value associated with said first area and a second light scattering intensity value associated with said second area;
- and
- means for categorizing said print medium based on a comparison of said first light scattering intensity value and said second light scattering intensity value.
A computer readable medium having computer implementable instructions comprising steps for:
- selectively printing at least one ink to a first area and a second area of a print medium, wherein said at least one ink is applied to said first area at a higher density than said second area;
- determining a first light scattering intensity value associated with said first area and a second light scattering intensity value associated with said second area;
- and
- categorizing said print medium based on a comparison of said first light scattering intensity value and said second light scattering intensity value.
