Abstract
In an example of recording medium identification method, a digital image of a line or a dot printed on a recording medium with a printer is captured by an image sensor. From the digital image, a microprocessor (operatively connected to the image sensor), digitally measures a width of the line, a diameter of the dot, an area of the dot, or a perimeter of the dot. The microprocessor identifies a type of the recording medium based on the width, the diameter, the area, or the perimeter. In response to the identification of the type of the recording medium, a print setting for the type of the recording medium is selected.
Claims15
A recording medium identification method, comprising:
- capturing, by an image sensor, a digital image of a line or a dot printed on a recording medium with a printer;
- from the digital image and by a microprocessor operatively connected to the image sensor, digitally measuring a width of the line, a diameter of the dot, an area of the dot, or a perimeter of the dot;
- identifying, by the microprocessor, a type of the recording medium based on the width, the diameter, the area, or the perimeter;
- and
- in response to the identifying of the type of the recording medium, selecting a print setting for the type of the recording medium.
A printer, comprising:
- an inkjet applicator to deposit ink to form a line or a dot on a recording medium;
- a vision system including an image sensor to capture a digital image of the line or the dot;
- and
- a microprocessor operatively connected to at least the image sensor, the microprocessor to:
- digitally measure, from the digital image, a width of the line, a diameter of the dot, an area of the dot, or a perimeter of the dot;
- identify a type of the recording medium based on the width, the diameter, the area, or the perimeter;
- and
- select a print setting for the type of the recording medium in response to the type of the recording medium being identified.
A method, comprising:
- capturing, by an image sensor, respective digital images of respective lines or respective dots printed, by a printer, on at least two different types of recording media;
- from each of the respective digital images and by a microprocessor operatively connected to the image sensor, digitally measuring a width of the respective lines or a diameter, area, or perimeter of the respective dots;
- generating a known set of line widths, a known set of diameters, a known set of areas, or a known set of perimeters for each of the at least two different types of recording media from the measured widths, diameters, areas, or perimeters;
- and
- rendering the known set of line widths, the known set of diameters, the known set of areas, or the known set of perimeters accessible to the microprocessor during a test print for real-time identification of a type of recording medium being used in the printer.
