Printer Method

Start by Creating the artwork with drawing software.  We use Corel Draw, others use Adobe illustrator
Then print the design onto template paper fed through a plotter.
As you can see we made wooden extensions to hold the big roll of paper away from the plotter.
The plastic keeps it dry.  (it is near our carving stations)
printing a template ice
Printed 20″ x 40″ template
We found the plotter on Ebay for $600 delivered
It is an HP DesignJet  750C
