Thanks for the welcome and info. I figured I'd give an update since you guys were nice enough to help. I did some testing on a few scraps of hard maple and wasn't impressed with the results of using the General Finishes HP TopCoat to transfer a mirror image. I tried different amounts of pressure and different amounts of the poly but there would always be some spots where the laser toner rubbed off of the wood as I removed the paper after it dried. I tried letting it sit anywhere from an hour to a full day and no improvement, so I tried using Acetone. That transferred less of the image onto the wood.
I make custom furniture and cabinetry in my one man shop. This guitar building thing is just a hobby for me that I get into when I have a bit of free time between or even in the middle of commissioned projects. Nothing for a week? Start a guitar build. Finishing room is full of stuff drying? Sand a body. Anyway, normally I brand my work with a branding iron. Heat it up, press it to the piece, lightly sand over it to clean it up then off to the finishing room it goes. I have one iron with one of my logos that is 2"x2" and another one iron with my other smaller logo on it that I use for smaller pieces which is 3/4" tall by 2.5" wide. Looks good on the back of cabinets, edges of cutting boards, and undersides of desks. I only make a couple guitars a year and usually they're for me. I haven't branded or put a logo on any of the guitars I've built so far I thought about using my small logo branding iron to brand the headstock on the guitar I'm working on right now, but I don't want my guitars to say "MY LAST NAME CUSTOM WOODWORKS". It would somewhat fit, but not the full idea I'm going for. So I pulled up photoshop, copied my smaller logo then altered the text to say "MY LAST NAME CUSTOM GUITARS". I sized it to fit nicely on a headstock. That's what I was printing mirror images of to try the poly and acetone stuff. Since that didn't turn out as nice as I wanted, I ordered some waterslide decal paper and will try that on some scrap maple once it comes in.
