Digital printing technology for quartz surfaces.

Chromia expands the aesthetic possibilities of quartz surfaces, enabling complex patterns and natural stone-inspired designs.

Through a high-energy thermal treatment, color diffuses deep into the material, enabling high-gloss finishes and superior resistance to scratches and UV exposure.

Beyond surface decoration

While sublimation relies on gaseous diffusion to color the slab surface, resulting in shallow penetration, Chromia employs a solid-phase high-energy diffusion process that enables color to penetrate the resin matrix of the slab.
This enables deeper, more stable and permanent decoration and allows polishing without compromising the image.

Industrial-scale process

Expanding aesthetic potential

Chromia is not simply a digital printer. It is a complete technological process designed for industrial-scale production and capable of producing up to 120 slabs per 8-hour shift with one printer. Key stages of the process:

Deko-HD primer application for ink adhesion
High speed Ink-Jet Printing, 600x600 dpi
Thermal treatment between 180°C and 210°C
Slab finishing for high-gloss or matte effects
X-Armor for increased gloss and UV resistance

Each phase is optimized to ensure precise decoration, deep color diffusion and consistent quality.
The technology can be applied to slabs produced with quartz, bioquartz, cristobalite or glass aggregates, expanding the aesthetic potential of Bretonstone® materials.

Technological Highlights

The Chromia printer uses eight colors at 600 × 600 dpi. The printing unit moves at high speed via linear-motor systems while the slab remains stationary. This eliminates positioning and movement inaccuracies and guarantees consistent print precision.

/ 01

Ink-Jet Printing
Chromia employs a high-energy diffusion process that allows color molecules to penetrate deeply into the resin matrix of the slab (up to 300 microns).
Chromia dye molecules measure 3 to 5 nanometers – significantly larger and more stable than sublimation dyes. This creates a permanent, sub-surface decoration integrated within the material, ensuring long-lasting visual depth and structural stability.

/ 02

High-diffusion technology
Thanks to deep color integration, slabs can be polished to achieve high-gloss or satin finishes without compromising the decoration, ensuring maximum flexibility in surface finishing.

/ 03

High-gloss or matte finish
X-Armor increases gloss and image depth, improves stain resistance, prevents fingerprints, and enhances UV resistance.
It creates an indissoluble electrochemical bond with the slab surface, forming an invisible protective layer.

/ 04

X-Armor
Before digital printing, a water-based organic promoter is applied to the slab surface to ensure optimal ink adhesion by anchoring micro-droplets with extreme precision.
It enhances image sharpness and quality and promotes uniform color penetration into the polyester during the thermal phase.

/ 05

Deko HD Application
High-energy thermal treatment in modular hot-air ovens operating in controlled temperature between 180 and 210°C. It is during this phase that deep molecular diffusion occurs.
The uniformity of temperature, with the possibility of modulation between the lower and upper surfaces, ensures the perfect flatness of the processed slabs.
