AYou can print it out in the size you need, cut it out and use it as a template for gumpaste... I'm not sure if that's the easiest way... I'm just brain storming... Maybe someone will chime in with a better idea.

What about using an edible image and cutting it out? That would probably be a PITA though...

Maybe you could cut out a stencil, lay it flat on the cake and then use a sponge to add the color? Or black royal icing maybe?

It looks hand-painted to me. You can blow up the logo to the size you need and then print it out on paper. Use a pin to prick points to give you a guide. I use gel color as paint. It will generally fill in the pin pricks.  Some other people print a mirror image of the logo and then trace with a graphite pencil to give the impression.  Graphite is non-toxic but I don't prefer that approach.

Great ideas! Thank you all

APersonally I would (and have successfully done before) print out a copy of the logo on regular ol' paper, cover it with wax paper, melt some chocolate and pipe over the logo using it as a template. Be sure to have this on a cookie sheet so that you can put the whole thing in the freezer to set. This makes it a piece of cake to peel off the design and place it on the cake. You only have a couple minutes to successfully do this, so work fast! Also you can work slowly and reheat chocolate as needed and make the lettering smooth by using a toothpick to push around the chocolate. Line it all out first making sure all the letters touch, then full in. HTH
