What Resolution Reveals at Arm's Length

Borduas worked with palette knife and brush in thick, decisive strokes, so a weak reproduction fails in a specific way. Edges smear. Where a knife stroke should end in a hard ridge of paint, a low-resolution file produces a soft gradient. Hold the print at arm's length and look at the boundary between a dark mass and the ground around it. If the edge is fuzzy or the surface shows a faint grid of pixels, the source file was too small for the print size.

The practical threshold is straightforward. A reproduction needs roughly 150 dpi at final size to survive close viewing, and 300 dpi to look convincing from a metre away. A 60 cm wide canvas edition therefore needs a source file of at least 3,500 pixels across. Sellers who work from good scans state this openly. Sellers who cannot answer the question are telling you something, and the answer is usually that the file came from a book plate or a web image.

The same test applies across formats. A canvas edition such as a canvas edition of a gestural work hides softness better than paper does, because texture absorbs some blur, while a framed poster behind glass exposes it. Neither format fixes a bad file.

Colour Accuracy and the Problem of Black

Borduas's palettes run through white grounds, earth tones and dense blacks, and black is where cheap reproduction fails first. Inkjet printing that lays down too much black crushes the brushwork inside his dark masses into a single flat shape. Too little, and the blacks turn brownish grey. Compare the print against an authoritative reproduction of the same painting, ideally a museum's online image viewed on a calibrated screen, and look specifically at whether the interior detail of the dark areas survives.

The whites deserve equal attention. His early figurative work and his later abstraction both depend on an active, warm white ground rather than a neutral paper white. A reproduction printed with a bright optical brightener will read colder than the original. This matters for placement too, since the palette's earth tones and whites interact differently with interiors depending on how faithfully they are printed, a point covered in more detail in our guide to Borduas's colours and modern interiors.

One honest caveat. Every reproduction shifts colour somewhat, because paint and ink behave differently. The question is not whether a print is perfectly accurate but whether the shifts are small and consistent or obvious at a glance.

Framing, Scale and the Seller's Honesty

Framing choices affect perceived quality more than most buyers expect. Borduas's paintings were unstretched canvases with raw edges for much of his career, so a heavy ornate frame imposes a period he did not work in. A simple thin frame or a clean canvas wrap suits the work better. Glare is the other trap. Glass over a poster will bounce light across his high-contrast surfaces, so matte finishes or canvas formats handle bright rooms better.

Scale is the final check. His compositions are dense and gestural, and shrinking them to a small poster size compresses the brushwork until it reads as texture rather than gesture. A larger format preserves the rhythm. If you are weighing sizes for a particular room, the reasoning in choosing a Borduas print size for a living room applies directly. Note that Auvrique does not currently offer Borduas editions, so these criteria are for evaluating any seller's offering, whether a framed poster like a framed poster edition or a canvas.

The seller's willingness to answer questions about source files, dpi and colour management is itself a quality signal. Vague answers predict vague prints.
