Hello, we started in the sign business a couple years ago. It was an extension of another business we have. We made good with a Summa DC4 and a vinyl cutter. Prints not handled with the Summa DC 4 we outsourced. We recently bought a used Mutoh 1604. The only vinyl I have printed on is Oracal 3640. Seems to be doing the job well, but I am about to order more printable vinyl and was wondering if anyone has good suggestions for other intermediate calendared printable vinyl. We are using Onyx Rip Center. Looking for a good vinyl that will show bold bright colors.
