Update: I experience difficulties towards the tail of my printing with head strikes. It seems ink loading caused bowing and buckles that would eventually lead to headstikes that compoundedly would unregister my paper towards the end of my print.
I developed a workaround by printing on half of a larger sheet by manipulating a custom paper size in Print Tool. This in turn allowed me to minimize my margins because I used the remaining half of the sheet as a very long tail.
After drying I print the unused side and basically print two images separately allowing for discreet and separate blending of the three curves in Print Tool.
I wonder if this technic might be useful to others that can front load to avoid Pizza Wheels. The idea being that an extra long tail can defeat the requirement for extra large borders.
