Everything looks great on screen, PDF looks great, printing PDF is fine, printing from the viewer looks like the printer is running out of ink, or its trying to print it in 8-bit, it just looks bad.
The concave looks awesome and our clients love it, but they do a lot of printing and forcing them to always go to pdf first isn't an option.
