Description
Getting gloss varnish bubbles on your xTool Omni? Before you blame dust or the printer, look at this. I printed the same design, on the same blank, back to back, and got two completely different results - then figured out how to stop the bubbles 😍

I spent days testing curing power, ink modes, extra varnish layers and batching to figure out why gloss varnish bubbles in the first place - and the setting xTool Studio steers you toward can actually make it worse. The method I landed on is faster, uses way less varnish, and is basically bubble free.
