Ceramic Ink Formulation
Ceramic ink formulation refers to a type of ink specifically designed for printing on ceramic surfaces. It is used in various ceramic printing applications, such as decorating tiles, dinnerware, ceramic art pieces, and other ceramic products. Ceramic inks are formulated to withstand high temperatures and adhere well to the ceramic substrate.
key aspects related to formulation
- Composition: Ceramic inks are typically composed of a mixture of ceramic pigments, glass frits, binders, solvents, and additives. The ceramic pigments provide the desired colors and effects, while the glass frits act as a flux that melts and fuses the pigments to the ceramic surface during firing. Binders help hold the ink components together, solvents are used to adjust the ink viscosity and aid in application, and additives may be included to improve ink flow, drying, and other ink properties.
- Heat Resistance: Ceramic inks are formulated to withstand high temperatures during the firing process. They need to be able to withstand the heat of kilns or other firing methods commonly used in ceramic production. The ink composition, including the ceramic pigments and glass frits, ensures that the ink is stable and remains intact when exposed to high temperatures.
- Adhesion: Ceramic inks are designed to adhere well to the ceramic surface, ensuring good bonding and preventing the ink from peeling or fading over time. The ink formulation and firing process create a strong bond between the ink and the ceramic substrate, resulting in long-lasting and durable prints.
- Color and Effect Options: Ceramic inks offer a wide range of color options and effects. They can be formulated to achieve vibrant colors, metallic finishes, gloss or matte effects, and even textured or raised surfaces. Ceramic ink manufacturers often provide a catalog of colors and effects to choose from, or they can create custom formulations to meet specific design requirements.
- Firing Process: After the ceramic ink is applied to the ceramic surface, it undergoes a firing process to bond the ink to the substrate permanently. The firing temperature and duration depend on the specific ink formulation and the type of ceramic being used. During firing, the glass frits in the ink melt and fuse with the ceramic, resulting in a durable and permanent decoration.
- Food Safety and Durability: Ceramic inks used for dinnerware or food-related ceramics need to comply with safety standards and regulations. They are formulated to be food safe, meaning that they do not release harmful substances or contaminants that could affect the food or the health of individuals. Additionally, ceramic inks are designed to withstand normal wear and tear, maintaining their color and quality even with regular use and washing.
Ceramic inks enable the decoration and customization of ceramic surfaces, adding visual appeal and artistic value to ceramic products. Our formulation, heat resistance, adhesion, and color options make them suitable for a wide range of ceramic printing applications.
How to make the ceramic ink?
These ceramic inks are generally composed of inorganic pigments as colorants and an ink solvent for jetting. The inorganic pigments need to be highly dispersible in the ink solvent to prevent nozzle clogging and thermally stable above 1000 °C during the firing process in ceramic product manufacturing.
What is ceramic ink and its uses?
Ceramic inks are simply carriers of ceramic fine particles metallic oxide pigments (not raw colorants but preferred stain powders) that are used in automatic application techniques. Depending on the application technique, these mediums can be thick and flow like a printing ink. Ceramic inks offer a viable option for decorating glass products. Made from a combination of fine glass particles and metal oxide pigments, ceramic inks have been used as an ideal choice in glass printing for many years.
