Slate coasters are a pretty straightforward UV print on the xTool O1 Omni and a 
good place to start with custom coasters. I’m still early in my long-term testing,
so take this as a starting point.

I scan and align the coaster designs in xTool Studio, pick the white and color layers,
and set up a flat UV print. I also get into ink costs, estimated print times, RGB
versus CMYK, and the Rock/Stone preset.

Design choice matters a lot on dark slate. Graphics with lighter colors tend to 
come out better, and I point out where some of my own graphic picks may not have
been the best fit.

I finish with a scratch test to check durability, then go over pricing based on 
material and ink costs, plus some ideas for coaster variations you could sell.
