You are looking at a print on a screen that emits light. The print that arrives reflects light off paper. The colours cannot match exactly, but you want to know: will the red be that red, or will it arrive dull, shifted, wrong?
Most galleries will not tell you, because most galleries do not know. Here are the five facts that determine whether a print holds accurate colour, and how to find them before you pay.
One: What the Paper Is Coated With
Matte paper has a coating that scatters light. Glossy paper has a coating that bounces it back. Lustre sits in between. The coating changes how much ink the paper accepts and how much the colour saturates.
A matte coating absorbs more ink and returns less light, so dark tones stay dark but bright colours lose a small amount of pop. A glossy coating reflects more light, so bright tones can look brighter, but fingerprints show and glare becomes a problem under direct light. Lustre reflects enough to keep saturation but scatters enough to avoid glare.
If the seller does not name the coating, the seller does not control it. A print described only as “high-quality paper” or “premium stock” has no coating guarantee, which means no colour guarantee.
Printasso prints on museum-grade archival matte paper with a coating designed to hold pigmented inks without bleed. Matte means the red you see at an angle is the red you see head-on. The coating is named because it is specified.
Two: Whether the Ink Is Dye or Pigment
Dye ink soaks into the paper. Pigment ink sits on top. Dye is brighter on day one. Pigment lasts decades without shift.
Dye gives you more saturation in the first year, then fades under light – especially UV. Pigment starts slightly less saturated but holds that colour for twenty years or more under glass, longer in indirect light. If a print uses dye ink and does not say so, it will look good in the photo and tired on your wall in three years.
If the ink type is not stated, assume dye. Pigment costs more to run and printers who use it say so.
Printasso uses pigmented archival inks, which means the colour in five years will be the colour that arrives. The ink is named because the longevity is real.
Three: What Gamut the Printer Covers
Gamut is the range of colours a printer can produce. sRGB is the standard web gamut – what your screen probably shows. Adobe RGB is wider, covering more saturated greens and cyans. ProPhoto RGB is wider still, though almost no printer reaches it.
If the artwork file is in Adobe RGB and the printer only covers sRGB, the colours clip – they flatten to the nearest colour the printer can manage. Deep teals become muddier. Bright magentas drop toward red. The print is not wrong, but it is not all the way there.
A seller who does not state gamut coverage either does not know or knows the answer is sRGB-only. A seller who covers Adobe RGB will tell you, because it costs more and produces better colour in the saturated ranges.
Look for a line that says “wide gamut” or “Adobe RGB” or gives a percentage of a colour space. If you do not see it, you are getting sRGB, which is fine for most work but not for all.
Four: Whether the Artwork File Is RGB or CMYK
Screens are RGB: red, green, blue light. Most consumer and fine-art printers are RGB printers using RGB files. Commercial offset printing is CMYK: cyan, magenta, yellow, black ink.
If someone converts an artwork from RGB to CMYK and then prints it on an RGB printer, colours shift twice – once in the conversion, once in the print. You lose saturation and you gain unpredictability. CMYK is for offset lithography, not for inkjet or giclee.
A print-on-demand service that does not say what file format it uses is usually handling RGB correctly, but if the artwork was supplied in CMYK and nobody checked, the red you saw will arrive orange or brown.
The fix: the artwork should be created or converted to RGB before printing, and the printer should accept RGB files natively. If a seller talks about “CMYK colour accuracy” for an inkjet print, they are confused and the print will show it.
Five: Whether the Printer Is Calibrated
A calibrated printer has been profiled – measured against a known colour target so that when the file says 100% red, the printer prints 100% red, not 98% red and 4% yellow.
Calibration drifts. Nozzles clog, inks age, humidity changes. A serious print studio recalibrates weekly or monthly. A print-on-demand factory may calibrate once at setup and never again. The colour shifts over time and nobody notices until a client does.
You cannot check this yourself, but you can ask: “How often do you calibrate?” If they do not know the word, the answer is never. If they say “regularly” without a number, the answer is never. If they say “every batch” or “monthly,” you have a real answer.
Printasso prints to order in the United States on printers that are maintained and profiled. The colour that arrives is the colour the file described, within the limits of matte paper and pigmented ink.
What You Actually Do With This
Before you buy a print, look for five lines: the paper coating, the ink type, the gamut, the file format and the calibration claim. If three of the five are missing, the seller is not managing colour. The print may look fine or it may not, but you are guessing.
The red you see on your screen will always be brighter than the red on matte paper under indoor light. That is physics. But if the seller controls those five variables, the red will be the correct red, and the print will look like the artwork, not like a guess.
Printasso lists the paper, the ink and the process on every product page because those facts are how you know what arrives. The coating is matte, the inks are pigmented and archival, the gamut is managed, and the file is RGB. The print ships flat and unframed, free within the continental United States, and the colour is the colour the artist specified.
If you are buying a print somewhere else and you do not see those facts, ask. If they cannot answer, you are paying for a guess.
