I took your original logo and added a twist to it, making it look like paper being taken through a printer, applying the CMYK color layers and then the paper coming out of the printer or off the press. This allows it to be just small change to the original yet the dba to be its own. The font on #23, #24 and #26 is a little different than what you used on ChiefSigns but fits the movement of the icon where the 'R' and 'A' attach and the 'I' and 'X' attach at the bottom with a flow.
I added #58, #59 and #60 with the Digital Printing in the designs. Funny thing is I sketched an Indian head with the CMYK feathers shaped like pieces of paper when I first started looking for ideas for your contest but didn't see anything in the brief or in your original branding that looked like that is the basis of the name so I didn't digitally render any of my sketches. When I saw the designer who used the chief head move to 2nd I was like "Dang!" ha! I went ahead and added a profile of a Chief's face on #60 to tie that in without having to change the design much, yet get that subtle icon in there.
