Because of this some giclee printmakers began using both dyes in the process. This has lead to the formation of a standards organization to certify that the fine art dyes are being used. Several artists have produced limited edition giclee editions that have literally been repainted over with acrylic paint thus creating a near original numbered graphic. Mechanically Produced Processes A. Offset Lithography is usually a four color process where the image is photographed and color separations are made for red, yellow, blue and black. Variations on color are created by the varying dot pattern density and overlaying dot patterns for each color.
Offset lithography is purely a mechanical process.
It is used for the printing of magazines, brochures and posters. Several artists have found this to be a good process for producing inexpensive signed and numbered limited editions for the limited-means collector. However, the edition quantities are usually in the thousands as in posters. B. Canvas transfers are essentially offset lithographs where the image has literally been lifted off the paper and placed on canvas. The image looks as though it was painted on the canvas because of the texture of the canvas.
