Step-by-Step Process: How Digital Ink is Applied on Tiles
Digital inks have transformed the tile manufacturing industry by enabling highly detailed, vibrant designs that traditional methods struggle to achieve. Using advanced technology, these inks allow manufacturers to create durable, colourful patterns with precision and efficiency.
What Are Digital Inks in Tile Manufacturing?
Digital inks are specially formulated inks designed for
direct application on ceramic tiles through digital printing technology. Unlike
conventional printing methods, digital ink for tiles
offers exceptional colour fidelity, sharpness, and customization. These inks
integrate with ceramic stains and glaze stains to ensure colour durability even
under high-temperature firing.
Step 1: Preparing the Tile Surface
Before applying digital ink, the tile surface must be clean
and free from dust or grease. The tiles are typically pre-treated to improve
ink adhesion and ensure that the design lasts through subsequent processes like
glazing and firing. Surface preparation may include washing, drying, and
sometimes light sanding.
Step 2: Designing the Print
Designers create high-resolution digital images using
graphic design software. These designs can range from simple patterns to
intricate artwork, allowing for maximum creativity. The digital format ensures
that the pattern can be precisely controlled, resized, and repeated without
losing quality.
Step 3: Loading the Digital Ink Printer
The prepared design is uploaded to a specialized digital
inkjet printer configured for tile printing. These printers use vibrant digital
inks that contain fine ceramic pigments, allowing them to bond seamlessly with
ceramic stains and glaze stains. The inks are carefully selected for their
compatibility with tile surfaces and firing conditions.
Step 4: Printing the Design on Tiles
The printer applies the digital ink directly onto the tile
surface. This step involves a controlled spray of microscopic ink droplets to
accurately reproduce the design. Thanks to digital technology, the process
supports multiple colours and gradients, producing rich, vibrant prints with
excellent detail.
Step 5: Applying Glaze Stains (Optional)
In many cases, after the digital ink is applied, a layer of
glaze stains is added. Glaze stains serve both decorative and protective
functions. They enhance the tile’s surface texture and provide a glassy finish
that protects the printed design from wear, scratches, and moisture.
Step 6: Drying and Fixing the Ink
After printing and glazing, the tiles undergo a drying
process to stabilize the ink and glaze layer. This step prevents smudging and
prepares the tile for firing.
Step 7: Firing the Tiles
The final and critical step is firing the tiles in a kiln at
high temperatures. This process vitrifies the tile body and fuses the digital
inks, ceramic stains, and glaze stains permanently into the surface. The firing
ensures that the colours remain vibrant and the design withstands everyday use,
including exposure to sunlight, cleaning agents, and physical abrasion.
Why Use Digital Inks and Ceramic Stains?
- Vibrancy
& Precision: Digital inks provide rich, vibrant colours that are
difficult to achieve with traditional printing methods.
- Durability:
When combined with ceramic and glaze stains, the colours fuse with the
tile surface for long-lasting resistance to fading and wear.
- Customization:
Digital printing allows for quick changes in design, supporting
personalized and limited-edition tile collections.
- Efficiency:
The process reduces waste and speeds up production compared to
conventional printing techniques.
The application of digital ink on tiles involves a detailed
and precise process that combines innovative printing technology with
traditional ceramic science. From surface preparation to high-temperature
firing, each step plays a crucial role in producing tiles that are not only
visually stunning but also durable and practical.
