Ceramic Printing Techniques: A Complete Guide

Ceramic printing applies a design to a ceramic or porcelain surface. The design can be a photo, a logo, or a pattern. Most methods use ink, pigment, or a transferred image. Almost all of them need heat to finish the job. Usually that heat comes from a kiln. Firing is what fuses the colour into or onto the surface for good.

People searching this topic usually mean one of two things. The first is which technique applied the design. That's screen printing, UV, digital inkjet, sublimation, or decal. The second is where the colour sits relative to the glaze. That's underglaze, in-glaze, or overglaze. These are two separate systems. They are not competing terms. One tile can carry a label from each list at once.

A digital ceramic printer works like a large inkjet printer. The "ink" is a specially formulated, vitrifiable ceramic pigment. It's sprayed onto a glazed tile, usually before the tile's main firing. Firing then fuses the pigment into the glaze itself.

This method transformed the tile industry. Digital ceramic printers first appeared around 1999 to 2000. Spain's KerraJet was an early pioneer. Digital printing has grown from a niche technology to roughly 60% of ceramic tile decoration worldwide. It has overtaken screen printing as the industry standard.

• Handles photos, gradients, and fine detail without a halftone texture.
• Cost-effective even for a single custom tile. No screen to prepare.
• As durable as any fired ceramic decoration, since the pigment fuses into the glaze.
• Needs industrial equipment most small studios don't own. That's why hand screen printing is still common outside large factories.

This is a different question from "which printing technique." It matters more for durability than the application method does.

Underglaze goes on before the clear glaze. The whole piece is fired once. The glaze seals the design underneath it. That makes underglaze the most protected, most durable option. It only needs one firing.

In-glaze goes onto an already-glazed tile, before that glaze is fired. During firing, the glaze softens. The pigment fuses into it. This gives deep integration between colour and glaze.

Overglaze (also called on-glaze) goes on top of a tile that's already been glazed and fired once. A second, lower-temperature firing fixes it in place. The lower temperature allows more vivid colours, ones that wouldn't survive the tile's original high-heat firing. But the decoration sits closer to the surface. That makes it the least durable of the three, though still permanent under normal use.

Any technique above (screen printing, digital, UV, sublimation) can pair with any of these three placements. That's why the same technique can give different durability results depending on how it's used.

Neither wins outright. They solve different problems.

Digital inkjet is better for photos, complex gradients, and one-off custom orders. There's no screen setup cost. There's no halftone texture. This is why digital now leads most of the ceramic tile industry.

Hand screen printing is better for large, identical production runs, since screens can be reused hundreds of times. It also suits studios that want full manual control over colour layering. Screen printing tends to leave a raised, tactile pigment layer. Some buyers want exactly that handmade look. Digital printing doesn't replicate it.

Ceramic decoration started with hand-painted underglaze and overglaze work. That's the tradition behind centuries-old majolica and hand-painted azulejo tiles. Industrial screen printing and decal transfer became the standard for mass production through most of the 20th century. Both could reliably decorate large volumes of identical tiles.

That changed around 1999 to 2000. Digital inkjet printers built for ceramic tiles first appeared at industry trade shows in Spain. Early machines were expensive and limited. Ink formulations and printhead technology matured through the 2000s and 2010s. Digital printing now accounts for an estimated 60% of ceramic tile decoration worldwide, up from under half that a decade earlier.

The newest development is ceramic 3D printing. It's an additive process, still mostly used for art and prototyping. It builds ceramic objects layer by layer instead of decorating a pre-formed tile.

It depends on one thing: is the design fired into the ceramic, or applied on top of it?

Underglaze and in-glaze decoration become part of the glaze itself. So does digital inkjet printing fired during manufacturing. These are as waterproof and scratch-resistant as the tile underneath them. They typically last for decades indoors without fading.

Overglaze decoration is also permanent, thanks to its second firing. It's slightly less protected, since it sits closer to the surface.

UV-cured and sublimated designs are genuinely durable for normal indoor use. But the ink sits on or in a coating, not fused into the glaze. That makes them more exposed to scratching, and more likely to fade under long-term direct sunlight, than a fired-in design.

Commissioning a one-off photo gift or a small custom order? Digital inkjet or sublimation will likely be faster and cheaper.

Want a hand-crafted, permanent design fired into ceramic or porcelain? Especially for a floor, feature wall, or anything exposed to daily wear or the outdoors? Hand screen printing with kiln firing remains one of the most durable options available. Just make sure the studio is decorating an already-glazed, fired tile, not risking breakage on unfired clay.
