I basically abandoned my previous printing chart and started anew with 11x14 (my current project)
Took 8x10s and cut them up. (same brand, same type, same paper) Got 3 test strips each and tested key areas. Once satisfied with parts, printed 11x14. Printed 3 of them with minor adjustments each. They are drying now.
I still cannot avoid needing to print full size prints and re-evaluate and re-adjust.
I'll have to wait until these are completely dry and redo them if necessary.
