I've tried both Gerbers and .brd files. I am putting the logo on layer 25 (tNames). I'm pretty sure I am missing something simple. Like I said, I can create the logos of different sizes, I just can't get it to render with OSH Park. I have also checked the Gerber with a Gerber viewer and they show fine.. I have tried lower the rez on the bmp file, but it still makes the tiny rectangles. I need tot find a way to lower the rez that is generated.
I am in contact with OSH Park, but they don't know either. I did find out that they use 300 DPI printers, not 200.
