Start With the Numbers Behind the File

The honest answer is that you cannot verify a scan by looking at a thumbnail on a product page. You verify it by asking one question and doing one calculation. Ask for the pixel dimensions of the source file. Then divide the longest edge in pixels by the longest printed edge in inches. If the result is 300 or close to it, the file supports a sharp print at that size. If it is 100, the seller is either printing soft or stretching a small image to fit.

This matters more with a painter like Ilka Gedo than with a photographically reproduced artist. Her surfaces carry visible brushwork and layered tone, and a low-resolution source flattens exactly the qualities worth paying for. A seller who cannot or will not state file dimensions is telling you something. A seller who answers with a precise figure, unprompted, probably did the scanning work properly.

What Quality Indicators Reveal in Person

Once a print arrives, the evidence is physical. Look at the finest passages first, the thin highlights, the edges of brushstrokes, the grain of the canvas texture if the original was painted on one. A true high-resolution capture holds a transition between tones across many pixels. An upscaled image shows stair-stepping, halos along contrast edges, or a waxy smoothness where texture should be.

Color is the second test. Compare the print against a published reproduction of the same work, in daylight, not under a warm lamp. Scans made without proper color calibration drift, usually toward magenta or a heavy yellow in varnished passages. None of this requires expertise. It requires ten minutes and two images side by side. The checklist below covers the practical checks.

If you are still choosing between formats while you assess quality, the substrate changes what you should look for, which is covered in more detail for the framed poster edition and for canvas work generally.

Reading the Seller, Not Just the Print

The market for reproductions of public-domain and estate artists is uneven, and skepticism is warranted. Some sellers photograph books or pull images from museum databases and print them large. The result looks acceptable from across a room and falls apart at arm's length. The reliable signal is not marketing language but specificity. Sellers who scan their own sources describe the process, state resolutions, and often show crops of fine detail at full zoom.

Price is a weak indicator on its own. A high price can fund proper scanning or simply pad a margin. A low price almost always means the scanning was skipped, because capture and color work are the expensive part. When comparing options for Gedo's landscapes, read how each seller describes their source before comparing prices, and see the wider guidance on buying a high-quality print online. If a listing shows a genuine detail crop, that crop is the seller putting their file where their claim is.

For a sense of how the same standard applies across formats, the comparison of the Giselle set design framed poster against canvas versions shows what to expect from each substrate at equivalent resolution.
