If the print is hand signed and the edition is over 300, it's probably a reproduction. This is same process as described under original prints, however a painting or other original artwork is photographed and the image is separated onto separate screens. Even though the printed image looks very much like an original serigraph, the result is still a reproduction. Xerox is an example of this type of copier. When viewed with a magnifying glass, there is no dot pattern as in an off-set, however, the reds and blues have a slight halo.
Dark colors have a raised appearance much like a silkscreen.
The process of scanning an original artwork into a computer and printing the image onto paper or canvas with an inkjet printer creating a continuous tone reproduction. These printers spray millions of dot of dye per second producing almost photographic results. Dot pattern can sometimes be seen with a 20X magnifying glass in light or pale colors. This pattern is not visible if the image is printed on a soft paper. Prices of these reproductions are usually much higher than off-sets because of production cost.
