we use Banners On A Roll, and the Front Side takes the cut vinyl nicely, sometimes an issue here and there with vinyl not sticking. We use Oracal 651 vinyl. The main trouble is the BACK of the banner. The cut lettering peels EASILY, falls off completely with the wind hitting it over a street.
We can't contact anyone today. Posting here on the off chance someone else has the same trouble, or knows a solution.
