What is the difference between UV printing and sublimation?
UV printing jets ink onto the surface and cures it instantly with UV light, leaving a hardened ink film bonded on top of the substrate. Sublimation uses heat and pressure to turn solid dye into a gas that penetrates a polyester or polymer coating and solidifies inside it. The practical consequence is substrate range: UV prints on almost any rigid material in any color, while sublimation only works on polyester or poly-coated blanks that are white or light in tone.
Can you sublimate onto metal, glass, or wood?
Only if the item carries a polyester coating applied specifically for sublimation, such as coated photo panels or coated drinkware. Bare aluminum, raw glass, natural wood, stone, and untreated plastics have no polymer for the dye gas to enter, so sublimation won't bond. UV printing has no such requirement and prints directly onto those substrates, typically with an adhesion promoter or primer where the surface calls for it.
Which lasts longer, UV printing or sublimation?
They fail in different ways rather than one simply outlasting the other. Sublimated dye sits inside the polymer, so it can't be scratched or peeled off and survives repeated laundering, though the dye can fade under prolonged direct sunlight. A cured UV ink film sits on the surface, so it resists abrasion, moisture, and UV exposure very well on rigid goods — and a clear varnish adds further protection — but on a repeatedly flexed textile the film can eventually crack.
Can UV printing print on dark or colored surfaces?
Yes. UV printing lays down a white ink underbase first, then prints color on top of it, so artwork stays accurate and opaque on black, dark, or colored substrates. Sublimation has no white ink at all — the dye is translucent and takes on whatever is beneath it — which is why sublimation blanks are almost always white or very light, and why dark-substrate jobs go to UV.
Which is better for apparel and fabric?
For polyester apparel that will be worn, washed, and flexed, sublimation is generally the better fit — the dye becomes part of the fiber and leaves no hand. UV printing is the stronger choice for rigid and semi-rigid goods, coated and technical fabrics, and any product in a dark color or non-polyester material where sublimation can't bond.
