I'd like to start printing a large number of digital images that we have accumulated.
There are several digital printers in my area. Walmart, Costco, a few drug stores, etc.
Before we start printing, I'd like to identify which is the best printing service.
What series of pictures or images should I send to each printer to compare their quality ? By images, I mean something that I could make up, like a color/tone burst, etc. Or is there something already on the 'net I could use ?
