Thumbtack Press is a California-based online print gallery. They use an 8 color archival ink jet process on heavy stock, and the prints normally range from $14.99 to $44.99.
Artists submit work for consideration, and according to the site, about 1% of the submissions are accepted - it is a very curated group of artists that are involved with the press. Artists retain the rights to their work sold through Thumbtack and 50% of the proceeds from each sale go to the artist. Thumbtack does all of the printing, packaging and shipping of the work to the patrons. Framing options are also available.
