No you don't, Mega Electronics sell a photo-coated aluminium panel
material. They are on +44 (1223) 893900 if you want to talk to them or
fax on +44 (1223) 893894. It isn't cheap, but it does look great. I
can't remember much about it because I gave my catalogue away. They
also do a replacement for the Dynamark style labels, which also give a
good result, and is cheaper and doesn't use any chemicals at all, just

Be more careful when making PCB's <g>...no seriously, don't peel off
the backing film until the last moment, having vacuum-cleaned the
board and the artwork and the UV box before you start. Leave the
paint-on-yourslef photoresist for crude things and/or clean-room
