Printing on vinyl?

Generally, vinyl is printed with a solvent based ink, so it “bites” into the vinyl.
I am not aware of any solvent based letterpress ink.

If it’s a short run, talk to a local sign shop.
If it’s a large run, then Stouse is online.

Van Son “Tough Tex” inks will cure on Vinyl bumper-sticker stock just fine. I have used this for printing on several plastic surfaces with success.

The Inks are quite resistant to UV, in the page I have linked below, they rate the various colors as to lightfastness. The higher the number, the more resistant:

Great! Thanks for the info! One more question, can you recommend a supplier for bumper sicker stock? Thanks again!

Oracal makes great vinyl for different applications. Go onto their site to find which product would suit your application and I believe there is alist of their vendors.

Good luck.

Hello 1021 Design,

Was your letterpress bumber sticker printing project a success? We are looking into printing bumper stickers for a project, and i found your post. Did you have a good experience with “Tough Text” ink and with oracal.com for the sticker stock? Or, did you come up with anything you liked better?

Thanks,
Nicolas
