Abstract
Official abstract text for this publication.
An embodiment implements a methodology for printing non-saturated text and lines in a way that removes the jagged edge problem. An embodiment uses a combination of two screens, e.g. AM screening and applying pure color. For example, according to the embodiment, the closer to the edge from the interior of text or lines, the less amplitude modulation half toning is applied and the more actual color or contone is applied. A particular algorithm for determining and using a blending parameter is provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A computer-implemented method for printing non-saturated text or lines, comprising the steps of: determining a distance, D, within which a pixel is considered close to an edge of the non-saturated text or line, wherein one end of D is referred to as D Max and the opposite end of D is referred to as D MIN ; providing a blending parameter, α, that is equal to zero at D MIN and is equal to one at D MAX ; for each pixel inside the non-saturated text…
