Abstract
The present invention relates to a method for reproducing images from precessionary art. The method comprises the steps of converting a piece of precessionary art to a multi-bit pixel depth bitmap, defining a first multi-pixel cell having particular dimensional attributes from the bitmap, determining a gray level for the first multi-pixel cell, dividing the first multi-pixel cell into two groups of alternating pixels with a first one of the groups being nominally on and a second one of the groups being nominally off, and deriving a first derivation cell depicting a maximum apparent gray from the first multi-pixel cell having the two equal groups of alternating pixels.
