How digital inks are revolutionizing the ceramic industry

Ceramics is an ancient art that has evolved over centuries, embracing new technologies and decoration techniques. Among the various innovations that have profoundly transformed the ceramics industry, digital inks hold a prominent position. Where ceramic printing was once limited to traditional techniques such as screen printing and offset printing, digital inks have opened doors to a universe of creative possibilities. They have revolutionized the ceramic sector by transforming smooth surfaces into detailed and personalized works of art.

In this article, we will explore the different types of inks and colors for ceramics, focusing our attention on digital inks. We will discover what they are, how they work and how they differ from other ink variants available on the market, ushering in a new era of ceramic design. We will see the technical characteristics of digital inks developed by Sicer laboratories, a historic manufacturer and supplier of raw materials for ceramic companies and a key partner for leading ceramic groups worldwide.

What is a ceramic ink

Ceramic ink is a suspension composed of a liquid part (a mixture of solvents), a solid part (pigment or material) and a dispersing component. The ceramic pigment consists of metallic oxides and other inorganic compounds that give the ink desired properties such as color, opacity and thermal stability. The dispersing component is responsible for maintaining the distribution of submicron solid particles as homogeneous as possible within the suspension, ensuring excellent adhesion of the ink to the ceramic surface during the firing process. Solvents are used to dilute the ink, facilitate its application and promote drying.

During firing, ceramic inks undergo a chemical transformation in which the solvent mixture burns, leaving the ceramic pigment permanently fixed on the surface of the ceramic object. This process gives ceramic ink remarkable resistance to high temperatures and long-term durability, making it ideal for ceramic decoration and customization.

Different types of inks for ceramics

When it comes to ceramic inks, it is important to understand the differences between the various available options. Some of the most common ones include:

  • Pigment-based inks: these inks are composed of a pigment base, binders and solvents. They are often used for decorating ceramic surfaces and they are known for their heat and light resistance. They are available in a wide range of colors and can be applied using techniques such as screen printing, pad printing or hand painting.
  • Glaze-based inks: glaze-based inks are obtained by mixing powdered glazes with additives and solvents. These inks are ideal for decorating tiles and ceramic objects and they are applied using screen printing or airbrushing. Once applied, glaze-based inks are fired at high temperatures to fuse with the ceramic surface, creating a glossy and vibrant effect.
  • Digital inks: digital inks represent one of the latest innovations in the ceramics industry. They are specifically formulated for use with specialized digital printers for ceramics. These inks consist of finely ground pigments suspended in a transparent liquid. Compared to traditional methods, they are directly printed onto ceramics through inkjet printing, allowing for high-resolution image reproduction and incredible detail. Digital inks are designed to withstand the high temperatures of the ceramic firing process.

Introduction of digital printing in ceramics

With the advent of digital ceramic printing, traditional inks have been completely replaced by digital inks characterized by improved printing precision, versatility, and ease of application.


Digital printers use advanced print heads that can apply inks with extreme precision, allowing for the creation of complex and detailed designs. This offers greater flexibility in design and enables high-definition results.

Furthermore, digital inks provide greater versatility in terms of available colors and shades. Thanks to the ability of digital printers to blend inks during the printing process, a wide range of custom colors can be achieved. This allows designers to express their creativity and create unique and original designs.

Another significant difference is the production speed. Digital printers can print quickly and efficiently, reducing production times compared to traditional methods. This allows for increased productivity and can be advantageous for businesses that need to meet rapid and flexible market demands.
