Make Prints of Small Paintings
To make prints of your painting, begin by scanning your small 8×10 inch canvas painting at 600 dpi. This will enable you to have enlarged sizes printed, like 11×14 inches or 16×20 inches. If your printer can manage larger paper up to 19 inches wide, you could scan a larger original. An 8×10 painting that has been scanned at 600 dpi can be converted into a 16×20 print at 300 dpi, the quality standard for printing for producing a clean, sharp reproduction.
After you have scanned your artwork, save the original scan as your “master copy.” Then use Photoshop, if needed, to fine-tune the levels a bit. For example, acrylic paints may reflect the scanner’s light, turning black into grey, so you can adjust the colors a bit darker to compensate for the fade. Once you have your adjusted 300 dpi version in PhotoShop, save it as a jpeg and a pdf (you never know which one a printer will require).
Some printers print with a laser printer so as to be of better quality, however, printing has come a long way. For example, for gallery quality reproductions I found this site online as one example that uses watercolor paper and a new type of inkjet printer for fine art. Some printers print on canvas paper as well. To sell or give your fine art as gifts, you can offer framed, matted or unmatted.
