Resolution and the detail you can see

A print is only as good as the file behind it. For a work with the geometric precision Norman Zammitt used, soft edges and banding show up quickly. A reproduction intended for a wall should hold at least 300 dots per inch at the final size, which is the figure most printers use as a working standard for sharp output. At that rate a 60 centimetre wide print needs a source image around 7,000 pixels across. Smaller files stretched to that size will look muddy, especially in the straight lines and colour transitions Zammitt built into his compositions.

The test is simple and it costs nothing. Hold the print at the distance you will actually stand from it, then look for jagged steps along edges and uneven colour blocks where the gradient should be smooth. A good reproduction keeps those transitions clean. A poor one reveals the grid. If you are comparing options, ask what size the original file was scanned or supplied at, and whether the printer enlarged it. That single question tells you more than most marketing copy does. where to buy a high-quality print is a separate question, and it matters less than the file itself.

Paper, ink and the surface under the image

The substrate changes how the image reads, and it changes how long it lasts. A matte or lightly textured paper usually suits Zammitt's colour fields better than a high-gloss finish, which can flatten contrast and throw glare across the wall. Canvas adds body and a slightly softer surface, which can suit larger pieces, but it also changes the detail threshold. A canvas edition should still be sharp at close range, not merely soft-looking. The difference between a good canvas and a poor one is often whether the pigment sits on top of the weave or sinks into it.

Ink matters as much as the paper. A print that looks fine out of the box can fade or shift if the inks are not lightfast. Ask whether the edition uses archival pigment inks and what paper or canvas stock it runs on. A seller who answers plainly is usually one who has thought about the reproduction, not just the sale. If you are weighing a framed poster against a canvas, how to choose between canvas and framed poster covers the trade-offs without the sales language. The point here is narrower. A good Norman Zammitt reproduction keeps the surface honest to the image.

The room test most buyers skip

A print that looks fine on a screen can read differently on a wall. Zammitt's colour relationships are deliberate, and the room around the print changes them. A north-facing room cools the whole image. A warm bulb above it can push the mid-tones toward yellow. The honest test is to view the proof or the sample in the light you actually live with, not in a showroom with controlled lighting. If you cannot see a sample, ask for a close crop of a flat area and a gradient area, because those are where the print quality shows up first.

Price sensitivity makes this harder, because cheaper prints often cut corners on file size and ink. That is the real risk to name plainly. A low price is not a flaw by itself, but a low price paired with no information about resolution or stock usually is. The buyer who asks for the file size, the finish and the ink type before paying is the one who avoids the pixelated copy. The rest is preference. what size fits a small living room is a separate decision, and it should come after you know the print is clean.
