Transfer printing — technique used to transfer designs and images onto ceramic surfaces. It involves the use of engraved copperplates or lithographic stones, along with a thin paper or gelatine bat.

The process begins by creating an engraved copperplate or lithographic stone with the desired design or image. The surface of the plate or stone is inked, and any excess ink is wiped away, leaving only the ink in the engraved areas. A thin, damp paper tissue or gelatine bat is then pressed onto the inked surface, allowing the design to be transferred onto the paper.

Once the design is transferred onto the paper, it is placed onto the ceramic surface. The paper is pressed firmly against the ceramic, ensuring good contact between the paper and the surface. The design is then transferred from the paper to the ceramic through a combination of pressure and moisture.

After the transfer is complete, the ceramic piece is fired in a kiln at a high temperature. During the firing process, the ink on the paper undergoes a chemical reaction, permanently fusing the design onto the ceramic surface. This results in a durable and long-lasting decoration.
