Patent ID: 8333468

Claim:
A method of printing an image on a substrate in a printing machine having at least a first printing unit and an inkjet printing unit, the method comprising the following steps: moving the substrate through the printing machine; printing a raster image of image dots on the substrate at a first moment using at least the first printing unit; and printing at least one contiguous area of inkjet dots in the same printed area as the raster image at a second moment after the first moment, the contiguous area of inkjet dots being printed using the inkjet printing unit, substantially all of the inkjet dots of the contiguous area being formed at dot locations that have similar surface wetting properties and that do not overlap with the image dots of the raster image, at least some of the inkjet dots each being formed at a location between two adjacent image dots that are separated by a smallest distance among all distances between any two of the image dots of the raster image.
