4. Drag the pattern into the canvas, or import it.

5. Drag the pattern to adjust its position and size to make it match the rock coaster.

6. In the lower-right corner, set parameters as follows:

  • Select Flat.
  • For Ink mode, select White+Color.
  • 2 white ink layers and 1 color ink layer


🌟 White ink is used to cover the original color of the substrate and provide a proper base for color printing.
For white or light-colored materials, one layer of white ink is usually enough. For dark-colored materials, 2–3 layers are recommended to ensure full coverage and accurate color reproduction.
The rock coaster is dark. Therefore, we recommend using at least two layers of white ink.
