Painting a white ceramic tile with layers of different colored enamel spray paint and lasering away the different layers to reveal color patterns. You can find the image here: https://www.laser-pics.com/image/animals-norton-97e30/
Clean the tile with an alcohol based cleaner and microfiber rag. Spray the bottom portion of the tile light blue. Spray the top left quarter of the tile yellow.
For layer two you will paint the entire tile dark blue
Paint the top right quarter of the tile purple
The final layer is the black top layer. Paint the entire tile black. Allow to dry.
A) Drag and drop image into imag-r
B) Crop the section of the image that you wish to engrave ( in this case I used square crop)
C) Adjust image size to .01 larger than what the material size actually is (this will give you some room to make sure that you engrave the entire piece)
•In this screen you will also set your dpi to 318 for the 5w and 10w
D) Next select the material button then select Norton white tile painted black (this is going to dither your image)
E) Last is to download the Image as your preferred file type (i typically download as a .PNG)
Import the image you just prepared into your laser software and set the layer settings (in lightburn it's important to use passthrough)
