DPI for the Pixel Guy

If you’re ever in need of full-color business card or postcard printing, look no further than 4by6.com, an online service for printing great quality cards. Recommended to me by Ethan and Josh, the process couldn’t have been easier — with templates and instructions on how to create high-res EPS files to be uploaded directly to them.
cardsJust download their templates, drop in your artwork, then a custom application uploads your completed files to 4by6. PDF proofs are posted online — once those are approved the cards are shipped out. The quality’s great, and it’s also very affordable. I recommend two things: order a free sample kit from them, and go with the satin finish (but not the satan finish).
As a web guy who always struggles when looking for print options, a find like this is gold.
