Five whites, and why the difference matters
Optic white has a fluorescent brightener added so it reads blue-white under shop light. Natural is undyed cotton — slightly warm, with visible fibre specks. Ivory, off-white and cream sit between them, progressively warmer.
A design proofed on optic white and printed on natural will look dirty. The same print on cream looks intentional. None of these is "wrong"; the mistake is approving a print against one white and buying another.
- Optic white: blue-white, brightens under retail lighting, most common for retail basics.
- Natural: undyed, warm, specks of cotton seed possible — this is not a defect.
- Ivory / off-white / cream: progressively warmer and softer, common in garment-dyed ranges.
What optical brighteners do to a print
Brighteners are fluorescent: they absorb UV and re-emit visible blue light. Under a shop light they make the shirt look whiter; under a camera flash they can blow out, and the print beside them can look yellow by comparison.
For DTG, a brightened white is also the hardest garment to build on: the printer adds a white underbase, and the two whites then differ slightly. On natural or cream the result is more forgiving.
Dye lots: the reorder problem
Every dye bath produces a slightly different white. Within one order the shirts match; between orders weeks apart they can differ enough to notice side by side on a shelf. This is normal in textile production and it is why buyers keep a physical swatch.
Practical defence: order the whole season in one run, keep one shirt as a swatch reference, and if you must reorder, ask for the same dye lot before assuming the price is the only variable.
What we hold in white
We hold 13 styles with a true white or near-white colourway, from $3.00 a piece at the top tier. All of them are 100% cotton except the activewear range, which is polyester and behaves differently under print.
If you need an exact white to match an existing garment, send a physical sample — no photograph and no PMS code resolves white reliably.
