A producthaving a data encoding patternprinted on it, the pattern defining a grid having a grid spacing, wherein the grid spacing has discontinuities arranged to compensate for a mismatch between the resolution at which the patternis printed and a required value for the grid spacing, the discontinuities being irregularly spaced across the product.

Data encoding pattern

A method and apparatus for producing a document having human-readable content and a position identifying encoding pattern. A printer places text or other content onto a substrate, such as paper, and a filter material application system applies transparent filter material to at least a portion of that content to only modify the reflectivity of the content at a predetermined wavelength. Because the reflectivity of the position identifying encoding pattern remains unchanged, it is distinguishable from the content and can be read at the predetermined wavelength. The position identifying pattern can take a number of forms including a number of dots printed at predetermined positions on the substrate on an imaginary grid.

Products with data-encoding pattern

A method for preparing a mask for multi-pass printing, comprises determining a characteristic satellite drop spray pattern for printing in a multi-pass mode with a printhead. Positions in the mask are filled with pass numbers. The pass numbers in a given position are selected based on considerations of interactions among main drops and satellite drops.

Method for preparing a print mask

A gesture related to portions of handwritten text is recognized. Furthermore, an action is performed against the portions of the handwritten text. The action is associated with the recognized gesture.
