I guess I am going to rephrase the original message (edited)
Is there a way to obtain a richer engraved color when using a 2 ply material (red top layer, black under-layer)?
Reason why I ask is because when the engraved gets exposed it looks like a nice rich black inside the house but as soon as I expose it under the sunlight the black turns more into a dark gray but a couple times I have engraved pieces that the black looks super deep and dark even outside (I guess by accident de-focusing?) So, what tips are out there to obtain a very rich color when using 2 ply material?
I might not be following 100%, but if you got a shallower engrave and are having focus issues, you may have accidentally done a defocused engrave. I purposely defocus my acrylic engraves, because it produces a smoother, better looking result on acrylic without having to use a high LPI. Perhaps this will help.
Thanks. I always use the same setting, maybe the machine did the defocused by itself since it’s faulty but I will play around with that and see if I can replicate the richer color!
I will say a number of folks comment that a 2nd fast engrave (max speed) over the area will “clean up” the residue of the top layer - that may also get you that darker underlayer.
