Playing around with jumbo craft sticks… someone once mentioned these are probably birch?
Anyway, a comparison between “white-washed” (left), painted (center), and bare wood (right). Same gcode, same 2.5 watt laser…
The “white-washed” is wood wetted with paint thinner, sprayed with flat-white paint, allowed to sit for a couple of minutes, and then wiped of most paint, and allowed to dry… ala @Bulldog
Painted is just simple light coat of flat-white paint, allowed to dry. And, of course, bare is totally untreated, just as it comes out of the package.
The paint definitely seems to give a “grainy” look to the image.
I have light air-assist running… maybe I need to roll it with a lint roller…
That definitely helps with the contrast and “grainy-ness”… now you can even see the “whites of their eyes”.
