I'm new to routers, but I use a laser for my signs. For 2 colors I'll paint the raw material, then mask it with vinyl sign transfer tape, engrave it, spray it with color #2 then unmask the material.

Most of the time I just paint the tops of the letters. I am working on a method using a vinyl cutter to create a mask that would let me spraypaint the sides as well without hitting the background. I haven't tried it yet.

I didn't know about this vinyl sign transfer tape. sounds a good ideaOriginally Posted by bpoulin
Thanks
Real nice, amazing what fantastic work lies beneath ordinary wood
Here is a single color masked then I just burned the wood with the laser. Here is where I get my masking Sign Warehouse And if that doesn't work they have vinyls specifically for spray masking, or sandblast masking I haven't experimented with any of these and a rotary cutter, it might take some experimentation.
Hey bpoulin, that’s the best info I got so far, thanks for the info
When you say “I just burned the wood with the laser” what guides the laser? I mean do you have the gcode or another code for this sign on your laser?
It's a Chinese CNC laser engraver, 1200x800mm cutting area. Check out the laser engravers forum here on CNCzone.
Sorry bpoulin, I know about the Chinese Laser Engravers. What I dont know is how the engraver knows where to burn the wood on that sign.
Sorry I misunderstood you. It's all in the software used to run it. I use vector art, but you can use grayscale bitmap images as well. It has to be a true black and white image the laser is pulsed on for black areas and off for white, and it runs like a printer back and forth across the image, and at the end of one line it will step up one line and repeat. When watching it, it looks like a giant inkjet printer. The machine uses a .mol file which I think is a machine operating language file. Probably similar to G-code.
Now I get it bpoulin, much appreciate your time
I knew about the Lasers but I didn't know how they work and now I got it
Thanks again
No problem, any more questions drop me a line. poulinphotography@gmail.com
