A method and apparatus for expanding a color gamut of a direct thermal printer is described. The method includes, in a three-color direct thermal printer having at least a print head, the print head including print head elements, dynamically adjusting a duty cycle of at least one of the colors depending on the color to be printed in each pixel of an image.

Expanding a color gamut of a direct thermal printer

The present application is directed to systems and methods for print alignment by a continuous feed printer. A sensor of a printer detects a first line of a pattern on a non-printing side of a printing medium, the pattern comprising two non-parallel lines separated by a predetermined distance at a predetermined position of the printing medium. The printer advances the printing medium a first distance, and the sensor detects a second line of the pattern. The printer identifies a horizontal offset of the printing medium from an expected location of the predetermined position proportional to the difference between the first distance and the predetermined distance.

Systems and methods for automatic print alignment

The invention provides an apparatus for enhancing full color images and may be used within a variety of computer peripheral devices such as a scanner which scans images initially recorded on a photographic medium, for example. The invention takes image data and applies a programmable set of parameters to the image data which govern color saturation and sharpness, inter alia. The image is then passed to a computer where a user may alter the parameter. The parameters are passed back to be reprocessed within the scanner and an updated image is then sent back the computer in real time.
