Depending on the “rub-down”, “dry-transfer”, “rub-on”, or what ever you want to call them, they are silk-screened to the transfer substrate. Just when you contact the vendor ask what method they use to create the graphics. For instance my key vendor will produce low-cost inkjet versions on an hp professional proofing printer for my client presentation models. Then 1,2,3, or 4 color offset prints for the focus groups, store intercepts, and preliminary marketing photo shoots.
The price I gave you earlier were for the offset print graphics. I just remembered how I was put in contact with my best vendor. Call the professional printer (Not Kinko’s or Office Max) in your area who has the best reputation for quality, they may be able to put you in contact with someone who can produce the rub-ons.
