What Actually Determines Print Quality

A reproduction lives or dies on the source file. If the seller scanned a small book plate or pulled an image from a website, the print will pixelate at any size above roughly 30cm wide, whatever the paper claims. A listing that states the image resolution, ideally 300 DPI at full print size, has usually been produced from a decent file. A listing that says nothing about resolution is telling you something too.

The second variable is ink. Pigment inks hold their colour for decades and resist fading on a bright wall. Dye inks cost less and fade faster, sometimes visibly within a few years near a window. Sellers proud of their process name the ink type. Sellers competing only on price rarely do. That silence is the cheapest red flag to spot.

Paper and canvas weight matters less than resolution but still separates tiers. Archival papers generally run 200 to 310 gsm. Canvas is typically a cotton or poly cotton blend around 350 to 400 gsm, stretched on a frame. Anything described only as 'poster paper' will arrive thin, glossy, and prone to curling in a frame.

Red Flags in the Listing

Skeptical instinct serves you well here. The most common failure is not bad paper, it is a soft or blurry image sold at an ambitious size. Watch for listings that offer the same file in sizes from 30cm to 120cm wide. A scan that survives 40cm will not survive 100cm, and the seller knows it. Fixed size options, or a note that larger sizes use a higher resolution file, are the honest pattern.

Also treat stock photography with suspicion. If the product image shows a room scene rather than a straight photograph of the print itself, you cannot judge colour accuracy, texture, or edge quality. A straight photo, or a close crop showing paper grain and ink density, suggests the seller has the physical product in hand and nothing to hide.

When you compare options, the same standards apply across formats. A framed poster such as Morning Mist as a framed poster should state its paper weight, while a canvas piece like Evening clouds on canvas should state the gsm and whether it arrives stretched. If you are weighing formats for a specific room, the choice between framed and canvas is covered separately in framed poster versus canvas for a hallway.

Questions to Ask Before Ordering

Three questions sort good sellers from indifferent ones quickly. Ask what resolution the file is at your chosen size. Ask whether the inks are pigment or dye. Ask for the paper or canvas weight. A seller who answers all three in one reply has a production process worth trusting. A seller who answers none, or replies with marketing language, has told you everything you need.

Returns policy is the final check, and it is a proxy for confidence. A seller who accepts returns on a misjudged colour or a print that arrives creased has production standards to protect. Check this before paying rather than after, since policies vary widely between marketplaces and individual studios.

One honest caveat about Max Jacob specifically. He was primarily a poet and his painted output is small, so high resolution source images are scarcer than for prolific landscape painters. That makes the resolution question more important, not less. If you are still choosing a subject, the strongest candidates for a modern room are set out in recognizable Max Jacob subjects for a living room, and sizing for a specific wall is covered in print size for a 120cm bedroom wall.
