Abstract
Methods and means for imaging on paper media are provided. A data file of an image to be printed is analyzed. A pattern for a clear fluid is determined according to the analysis. The pattern of clear fluid is applied to a paper media traveling in a particular direction, wherein the pattern is generally elongated along the direction of travel. The pattern of clear fluid is defined by a maximum width that is generally equal to the maximum width of the image to be formed. One or more colored inks are applied such that the image is formed and is supported by the paper media. The paper media exhibits reduced cockle as a result of the pattern of clear fluid.
Claims10
An apparatus configured to:
- determine a pattern in accordance with an image to be printed, the pattern configured to reduce cackling of a paper media;
- transport the paper media in a direction of travel;
- apply a clear fluid to the paper media so as to define the pattern;
- and
- apply one or more colored inks so as to form the image, the pattern at least contacting the mage and extending away there from, the pattern defined by a maximum width about equal to that of the image, the pattern being elongated in the direction of travel of the paper media, the pattern having a non-uniform thickness profile decreasing in thickness in at least one direction extending away from the image.
The apparatus according to claim I further configured such that the clear fluid does not underlie any of the one or more colored inks.
An apparatus configured to:
- determine a pattern in accordance with an image to be printed, the pattern configured to reduce cackling of a paper media;
- transport the paper media in a direction of travel;
- apply a clear fluid to the paper media so as to define the pattern;
- and
- apply one or more colored inks so as to form the image, the pattern at least contacting the image and extending away there from, the pattern defined by a maximum width about equal to that of the image, the pattern being elongated in the direction of travel of the paper media, the pattern decreasing in width in at least one direction extending away from the image.
A controller configured to:
- determine a pattern in accordance with an image to be printed, the pattern configured to reduce cockling of a paper media;
- cause a printing apparatus to apply a clear fluid to the paper media so as to define the pattern;
- and
- cause the printing apparatus to apply one or more colored inks so as to form the image, the pattern at least contacting the image and extending away there from, the pattern defined by a maximum width about equal to that of the image, the pattern being elongated in a direction of travel of the paper media, the pattern at least:
- decreasing in width in at least one direction extending away from the image:
- or
- having a non-uniform thickness profile decreasing in thickness in at least one direction extending away from the image.
