Resolution and the size you actually want

The first test is arithmetic, not taste. A reproduction file that looks fine on a screen can fall apart once it is enlarged. Ask for the native file resolution and the intended print dimensions. At thirty inches wide, a file at one hundred dots per inch will show softness in the edges of a figure or a roofline. At three hundred dots per inch the same image holds its detail. If the seller cannot state the file size in pixels or the dots per inch at your chosen dimensions, treat that as a warning rather than a mystery. A print that is upscaled from a small source image will read as smooth at a distance and grainy close up. That is the difference between a reproduction and a facsimile.

Papaloukas worked across town scenes, landscapes and figures, and the amount of surface detail varies by subject. A broad landscape can tolerate a slightly lower file resolution better than a portrait where the edge of an eye or a collar matters. Match the reproduction standard to the subject, not to the largest size on the shelf. If you are comparing two offers, ask which one was prepared from a higher resolution source. The cheaper option is often the one that was enlarged after the fact.

Paper, ink and the look of the surface

The second test is the material under your fingers. A thin paper will curl at the corners and show the wall behind it where the ink is lightest. A heavier stock holds a flat surface and gives the image a more even field. Canvas reproductions behave differently again. They carry a weave that can soften fine lines, which is sometimes desirable and sometimes not. Ask whether the surface is matte, satin or glossy, because that choice changes how the paint-like areas read under room light. A gloss finish can make dark passages look richer and can also show fingerprints and glare.

Colour is the part most buyers judge too quickly. A good reproduction keeps the separation between adjacent tones. Look for banding in skies and in shadows, where a smooth gradient should sit. If the blues in a sky collapse into a flat block or the shadows turn a muddy brown, the colour profile was not managed carefully. A seller who can show a close crop of a gradient or a detail of a shadow is usually more confident about the file than one who only shows the full image. That is where red flags and quality indicators in reproductions tend to show up first.

Edition numbers, signatures and what they mean

The third test is the paperwork around the image. A fine art print is usually issued in an edition, and the edition line tells you if you are buying a reproduction or something closer to an original print. Look for a number such as twenty-five of one hundred, and for the artist's name or a blind stamp where that is part of the edition. A reproduction that is sold as an open print without any edition language is not dishonest, but it is a different thing and should cost less. Do not pay for scarcity that the seller has not documented.

A signature on a reproduction is not the same as a signature on an original painting. Some reproductions include a printed facsimile of the artist's signature, and some do not. Neither choice makes the print better or worse on its own. What matters is that the seller is clear about what is printed and what is original. If you are comparing a framed poster and a canvas edition of the same image, the difference is in the support and the finish, not in the file. A framed poster edition and a canvas edition of the same image can both be well made, and they suit different rooms.
