If your work fits on A3 paper, this is the scanner that removes stitching from your life. The 3120's 12 by 17 inch bed swallows a full A3 sheet in one pass at up to 1200 dpi optical, which is comfortably beyond what giclee reproduction needs, and the LED illumination is even right to the corners.
For flat works on paper, drawings, watercolors, prints, and collage under a weight, the CIS limitation rarely shows and the value is unbeatable. If your surfaces are textured or you scan framed or mounted work, spend up on a CCD machine.
Our Pick
The best value in a true A3 flatbed for artists. A 12 by 17 inch glass bed at 1200 dpi optical means a full A3 drawing, watercolor, or lino print scans flat, evenly lit, and in one pass, at a price that used to buy an A4 machine.
Buy this if you make work up to A3 and are tired of stitching two letter-size scans in software. One-pass A3 capture removes the seams, the color shifts between passes, and half the workflow.
What we don't like
The CIS sensor has shallower depth of field than pricier CCD flatbeds, so anything not pressed flat to the glass (canvas texture, warped paper, thick impasto) softens faster. Software is functional rather than lovely.
