These people do not recognize the term original print, and don't think that there is any such thing. Typically, the work of art was made in one form, usually a painting or watercolor, and then copied either by hand or using photographic techniques in another form, often prints, poster, silk-screens. Remember though, an artist who copies a unique painting by making another unique painting is also technically making a reproduction. A print or multiple can be original - in which the artist himself put the image on the stone or plate, or a reproduction in which the image is photographically put on the stone or plate and the artist's hand is not involved. It refers both to original prints and to Tacky Market reproductions.
Posters are, for the most part, printed in unlimited editions.
A good, artistically viable print is not just a reproduction of a popular image made by an artist, but an extension of his entire artistic oeuvre. More and more often, respected artists are making prints because they see them as integral part of their work. I know many artists who have gotten stuck in their painting, who then turned to printmaking as a way to break away from the rigors of their studio. More often than not, they later find themselves approaching their painting in a fresh and freer way. T he price level for original prints is normally substantially lower than that of unique paintings because they are multiples and on paper.
