I offered to set up a qsl design/printing process for amateur radio operators a while back on here, but most people (okay just one) balked at the idea. I can make a card that anyone can send to a offset or screen printing company that not only looks good and sharp, but is not prone to water or damage in the mail. In effect - a real postcard. Not only that, but when they are exported to a jpeg graphic they still look reasonable. I use indesign and its a very flexible and powerful application for designing and preparing graphics for professional - or even casual printing.
