Visual and technical cues for Huguette Arthur Bertrand prints

A low resolution print looks soft at first glance and obvious up close. The real test is edge sharpness, tonal separation in the midtones, and whether the file was upscaled rather than scanned at native size.

The short answer

Check the file dimensions first. A genuine high resolution reproduction of a Huguette Arthur Bertrand work should carry at least 300 dots per inch at the intended print size, which for a 50 by 70 centimetre sheet means roughly 5900 by 8200 pixels. Below that, the image is likely upscaled and will show softness at the edges of forms. Zoom to 100 percent on a screen before you buy. Look for crisp transitions where a dark shape meets a light one, not a blurred halo.

What resolution actually means here

Resolution is a measure of how much image data sits behind each inch of printed surface. A poster printed at 72 dots per inch from a small web file will look fine on a phone screen and poor on a wall. The same file enlarged to fill a large sheet forces the printer to invent pixels it never had. That invention shows up as softness, banding, and edges that lose their definition. A good digital print starts from a file that is large enough to hold the detail the original actually contains. Anything smaller is a guess dressed up as a reproduction.

The number that matters is dots per inch at the final size, not the megapixel count of the source camera. A scan of a modest drawing can be excellent if it was captured at high resolution and not stretched afterward. A large painting scanned at low resolution will disappoint when printed big. Ask for the native file dimensions and the intended print size together. If the two do not line up at 300 dots per inch or close to it, expect visible compromise. The buyer who asks for that number up front avoids most of the disappointment.

What to look for on screen

Open the file at full size on a monitor before you commit. Zoom to one hundred percent and move across the image slowly. High quality digital prints keep their edges sharp where a dark passage meets a lighter one, and they hold separate tones in the mid range rather than collapsing them into a flat band. Low resolution files blur those transitions and often show a faint halo around shapes. Look near the smallest marks in the composition, because that is where a weak file gives up first. If the fine lines dissolve into mush, the file was enlarged beyond its real data.

Colour is a separate signal but it tells you something about the source. A print that has been pushed too far toward contrast will hide the weakness of a thin file behind artificial punch. A careful reproduction keeps the original balance and lets the detail speak for itself. Check the shadows near the darkest areas too. Crushed blacks with no gradation often mean the file was compressed heavily before printing. A good quality digital print preserves a range of tones even in the darker passages, which is one of the clearest signs that the source was handled with care.

Paper, size, and the cost of a weak file

The substrate changes how much resolution you can actually see. A matte poster paper hides some grain and can make a mediocre file look acceptable at a glance, which is exactly the risk for a buyer who wants sharpness. A smoother surface or a canvas transfer reveals edge definition more plainly, so the same file may read differently on different materials. Size matters too. A small print can get away with less image data because the eye does not resolve the same detail at a short viewing distance. A large print magnifies every shortage in the file, and the softness becomes the first thing you notice on the wall.

Price is not a reliable test on its own, but a very cheap large print usually signals a small source file that has been enlarged. That does not mean a higher price guarantees quality, only that the work of scanning at true resolution and managing the file properly costs something. If you want a print that holds its detail at arm's length, choose a size that matches the file rather than one that stretches it. The buyer who sizes the print to the available data usually ends up with a better object than the buyer who asks for the biggest possible sheet from a thin file.

A print that looks fine on a screen can still fail on a wall because the file was enlarged past its real data.

Signal	What you see	Likely meaning
Edge sharpness at 100 percent	Clean transitions between dark and light shapes	File likely holds enough data for the print size
Soft halo around forms	Blurred edge with a faint lighter ring	File enlarged beyond its native resolution
Midtone banding	Flat strip where tones should step gradually	Heavy compression or a thin source file
Crushed shadows	Dark areas with no visible gradation	Contrast pushed to hide weak detail

Resolution cues at a glance

Key takeaways

Ask for the file dimensions at the intended print size and check that they support at least 300 dots per inch.
Zoom to one hundred percent on screen and inspect the edges of shapes for soft halos or blurred transitions.
Choose a print size that matches the available file rather than stretching a thin source across a large sheet.
Treat a very cheap large print as a warning sign rather than a bargain, because enlargement usually costs less than proper scanning.

Related questions

Can I judge resolution from a small preview image on a website

Not reliably. A preview is usually compressed and downsized, so it hides both the strengths and the weaknesses of the file. Ask for the actual file dimensions or a full size sample before you decide. A preview can tell you whether the composition suits you, but it cannot tell you whether the reproduction will hold its detail on the wall.

Does a canvas print need the same resolution as a poster

Roughly yes, though the surface texture of canvas can mask some fine grain that a smooth poster paper would reveal. That does not mean a weak file becomes acceptable on canvas. It means the same file may look slightly different on each material. If you want sharp edges, start from a file large enough for the intended size on whichever substrate you choose.

What if the seller will not share the source file details

Treat that as a real limitation rather than a minor inconvenience. A seller who cannot tell you the file size or the scanning method may still sell a decent print, but you are buying without the information that matters most. In that case, order the smallest size that suits the space, because a smaller print forgives a thin file more than a large one does.
