Six Ways to Check
Telling an original painting from a print
Framed art found in estates falls into three broad categories: original paintings, original hand-pulled prints, and photomechanical reproductions. Originals and original prints can be valuable; photomechanical reproductions rarely are. The difference is not always obvious at a glance, especially with modern printing technology that can mimic brushstrokes and canvas texture. Six specific checks — done in order — will resolve most questions.
1. Examine the surface
Look at the surface of the work from multiple angles under good light. Original paintings have physical texture. Oil paintings typically show visible brushstrokes, ridges, and sometimes thick impasto — paint applied in mounds or peaks that cast tiny shadows when light rakes across the surface. The surface reflects light unevenly because the paint is not flat. Acrylic paintings can be thinner but still show brushwork and occasional ridges.
Prints are flat. The entire image sits on a single plane, and the surface reflects light uniformly. Some modern giclees on canvas are coated with clear gel to simulate brushwork — but the simulated strokes do not correspond to the actual image content. Hold the work under angled light. If the visible brushstrokes follow the forms (a face, a tree, a horizon), the piece is likely original. If the strokes are a generic random pattern unrelated to the image, you are probably looking at a giclee.
2. Look at the edges
For works on canvas, the edges are telling. An original painting on stretched canvas typically has paint that wraps around the stretcher edges — the artist's brush went past the image area, or the canvas was painted before stretching. The paint on the edge is continuous with the front surface. You can see the artist's working process where the image "ends."
Printed canvas, by contrast, usually has clean, sharp edges where the printed image stops. The edge may be white, or the printing may have been continued around the edge as a separate operation. Prints also often show a faint line where the image ends and the canvas wrap begins. Works on paper or board have different edge characteristics, but the principle applies: originals show evidence of the artist's process at the edges; reproductions show mechanical cut-off points.
3. Examine under magnification
A magnifying glass or jeweler's loupe (10x magnification is ideal) is the single most useful tool for resolving this question. Look at any area of continuous color, especially smooth skin, sky, or gradient backgrounds.
Under magnification, photomechanical prints reveal themselves as thousands of tiny halftone dots — circular or rosette-shaped marks arranged in regular patterns, typically in four colors (cyan, magenta, yellow, and black). The dots combine to fool the eye into seeing continuous color. If you see halftone dots, you are looking at a reproduction. Giclees and other inkjet prints show very fine inkjet droplets in irregular patterns — not the regular rosettes of older photomechanical printing but still a mechanical texture. Original paintings show continuous color and individual brushstroke marks under magnification. Original hand-pulled prints (lithographs, etchings, engravings) show specific ink patterns characteristic of their process but no halftone dots.
4. Check the back
The verso (back) of a framed piece carries critical information. On canvas paintings, the back of the canvas shows a woven texture. You can see the threads of the canvas and the build-up of paint soaking through on originals. On stretched originals, the stretcher bars (the wooden frame inside the canvas) often show age, wear, and hand construction; older stretchers have keyed corners and hand-cut components.
Printed canvas typically has a smooth, uniform back — often with a printed serial number, an edition mark, or a publisher's stamp. Printed board has a clean white or colored backing. Original oil paintings on board show paint seepage and physical traces of the painting process on the back. Look for labels from galleries, exhibitions, dealers, framers, or auction houses — these are provenance documentation and should never be removed or discarded. Labels on the back are often more informative than the front of the painting itself.
5. Pencil signature vs. plate signature
Signatures on prints come in two fundamentally different forms. A pencil signature is written by the artist in graphite (usually in the lower margin, outside the image), is unique to each individual impression, and indicates the work is at minimum an original hand-pulled print. A plate signature is a signature that was part of the printing plate — it is printed into every copy of the image and is identical on every impression. Plate signatures are common on photomechanical reproductions and indicate no hand-signing by the artist.
Check any signature with a magnifying glass. Pencil signatures show the physical indentation and texture of graphite on paper. Plate signatures show the same halftone or ink patterns as the rest of the printed image. A pencil signature — especially combined with a pencil edition number (12/50, 45/100) — is a strong sign of an original print.
6. Edition numbers
Original hand-pulled prints are usually numbered in pencil in the lower margin. The format is typically "X/Y" — X is the specific impression number in the edition, Y is the total number of impressions. A print numbered "45/100" is the 45th of 100 impressions. Low edition numbers (under 100) and proof impressions marked "A.P." (Artist's Proof) or "H.C." (Hors Commerce) are generally more valuable than impressions from large editions.
Photomechanical reproductions sometimes carry fake edition numbers, usually printed as part of the image rather than hand-written in pencil. Combined with pencil signature, a pencil edition number is strong evidence of an original print. An image with only a printed "limited edition" notation — no pencil marks — is likely a reproduction regardless of how convincing the limited-edition claim sounds.
