White Ink Adhesion to Acrylic when printing 2nd surface with flood white over 4 color.

I have been challenged to develop a print configuration that cures the White Ink over a 4 color print on Clear Acrylic (Second Surface). The White has been very sensitive to scratching shortly after the print has concluded - in fact it can be scratched with the brush of a finger nail. I would appreciate any input that may lead me to a more durable surface in this 2nd Surface print application.

Hi @drcleveland1963, I would recommend increasing the Overcoat value and modify the curing height. Hope this helps.
