HAHA, well, I haven't tested the purple yet, but my understanding it's better. I know the blues are. With the 1200x1200, the colors are better, but on most designs I see us still using 600 mode.
The prints on top of an underbase can be dang near neon. The raw cotton mutes the colors a little too much. Some of the pretreats out there will help with this. Mike, have you tried the new Image Armor underbase for lights? It's wicked. We are considering doing it to all shirts, because they colors are just that much better.
