Anyone have any success with photos on white tiles with a k40 or any C02?

Just getting into the laser world and got my hands on a k40 with a compound lens/mini grbl. So far its been a blast playing around with slate with LB.

Ive been starting to mess with white tiles aka NWT with mixed results. I havent used smokey beige because I cant find it so im trying with flat white for now. Im also using ImagR to process the photos which have worked great for slate but im struggling with tile.

Any tips or advice if its possible to get something decent not necessarily Diode level quality?

Haven’t done photo’s but I have done a number of ‘mugs’ using the same game.

I have a 50 watt ‘China Blue’ co2.

I’ve been working with a friend who lost his daughter at 36 to engrave a picture on slate.

One of the things I’ve found useful is processing an image via ImagR site and setting Lightburn to ‘passthrough’ so it doesn’t modify the image.

Problem with slate is that sometimes it’s dark, sometimes light…

These were done with that lens, I get the smallest ‘dot’ with it. The material determines what reasonable resolution you can maintain.

Here is a file from Russ Sadler that contains groups of dots at 0.1mm. Use the ‘zoom to selection’ when you load it or you won’t see it. It will let you check you dot size.

Good luck… post some pictures…

Take care


The biggest thing is getting your dot size as small as possible. You’ll probably want to get a lens specifically for this type of engraving. I’ve gotten good results on a 100w CO2.

Edit: Here are some ones I did forever ago. Black spray paint on white tile.
