There are some schools of thought that advocate split printing at G2 and G5 rather than G0 and G5. the reason being that G0 can muddy the highlights in some images. I've not tried this to back that up, but have used the G0 and G5 successfully.

Does the cross hatch method involve a set of strips at G0 going from say right to left, and then G5 from top to bottom on the same sheet rather than a seperate sheet for each grade?
