Start With Resolution and Proportion

The single most reliable indicator is resolution. A print pulled from a low-resolution image will show soft edges and visible pixel steps along Lozza's straight lines and color boundaries, and geometric abstraction shows these flaws faster than almost any other style. Ask for the file to be 300 dpi at the printed size. A 24 by 36 inch print at that standard needs a source file around 7200 by 10800 pixels. If a seller cannot or will not state this, assume the worst.

Proportion is the second check and it costs nothing. Look up the dimensions of the original painting, then compare the ratio to the print on offer. A print that stretches a square composition into a rectangle has been cropped or distorted, and with constructivist work that distortion is obvious once you know the original's shape. Sellers who care about fidelity list the original's dimensions and keep the ratio intact. Those who do not are usually working from whatever image they found online, which is also the profile of a seller likely to have color problems.

Paper, Ink and the Physical Test

Materials decide how the print ages and how it looks on the wall. A well-made reproduction uses archival paper of 200 gsm or heavier, or a properly prepared canvas, with pigment inks rather than dye-based ones. Pigment inks resist fading for decades under normal indoor light; dye inks can shift within a few years, especially in a bright room. The listing should name the paper or canvas and the ink type. Vague wording like quality photo paper is a warning sign, not a detail.

The physical checks are simple once the print arrives. Look at it under daylight, not lamplight. Flat color fields should be genuinely flat, with no banding, no streaks and no orange or green cast. White margins should be clean and trimmed square. If the seller offers framed work, the glazing and mount matter as much as the print itself, which is why some buyers prefer to compare framed and canvas formats before committing, as covered in the guide to choosing between canvas and framed poster for Oscar Dominguez prints, where the same logic applies choose between canvas and framed poster.

Reading the Seller Before You Pay

Most disappointment with public-domain prints comes from the seller, not the process. Because works like Lozza's are out of copyright or reproduced under open licensing, anyone can download a thumbnail and sell it printed large. The honest sellers distinguish themselves by stating where their source image came from, what resolution it is, and who prints it. Read the product description the way you would read a spec sheet. Absence of information is information.

Cross-check before buying. Search the seller's name alongside the word review, and compare their listed colors against an independent image of the original painting. If the same print appears on several marketplaces at wildly different prices, the cheapest version is usually the one printed from the smallest file. It also helps to read a broader buying guide before comparing shops, since the criteria for judging any reproduction online are the same from artist to artist buying a high-quality print online. And confirm the format you actually want, because canvas and paper behave differently with geometric work, a difference set out plainly in the comparison of canvas and poster formats canvas versus poster formats.
