Raster design question

I’m designing something to laser engrave onto a slate coaster and I had a few questions about the most efficient way to get the data into the laser. In this case it’s just going to be a raster image with no vector lines being traced.

When designing a piece like this is it best to use an image file such as png or a vector file? When using a vector file is it better to group all the separate parts of the design into one object or does it not make a difference?

Hi James, For most simple things, as long as your png file has the resolution you want, I don’t think there is any real need to have a vector file for raster engraving.

Just group everything together unless there is a need to have some part engraved differently (e.g. power).

There are some exceptions but that would depend on what control software you are using.
