ColorShop wood is approximately like Medium Proofgrade, but with color finishes. It comes masked, and the label advises that one side is preferred for engraving. The engraving side has a less heavy finish than the reverse, which actually feels slippery.
The sample I tried tonight cut well with the Medium Maple Plywood setting, Speed 170/Full Power. There may be a way to improve this–you can see a faint lightening of the color around the cut edge.
Here’s an engrave test on the “Plum” color. To get you started, I found that Speed 925, Power 60, 270 LPI made a nice mark that wasn’t too deep or too dark. If I engraved without masking detail got blown out fast but I didn’t spend too much time on that.
(I couldn’t find a way to erase the color layer and leave the wood underneath un-darkened–the samples are like that, and now I wonder if they were made with a rotary tool.)
At about $15 per 12" x 24" sheet, this stuff isn’t cheap, but it appears comparable to Proofgrade, and comes in new colors.
I got mine from Johnson Plastics, and the shipping charge came to about an extra $1 per sheet, which I thought was pretty good.
Tomorrow night I am cutting samples from all the colors I ordered and I will post an update with those pics.
