Re: printing on latex swim caps? Union Process Supply out of Ohio I think makes Rubber Ink. You definitely need a rubber ink. Nazdar and most major ink suppliers do not make an ink that will stick to ruibber.
That said, printing swim caps sucks. It's really no fun. Posters are fun. Stickers are fun. Shirts are fun. Swim caps... no fun. Unless there is a gip of cash in it, pass. Plent of cap suppliers offer it anyways. |
