Springback compensated die face
data as IGS (Optional Service Add-on):

Springback is a well known sheet metal problem. Using simulation technology, springback can be predicted to a reasonable degree of accuracy and then compensation can be made. Clients whom have requested "Springback
analysis and resulting color error map" can choose to go an extra step, by
"requiring" this option and having their die face design compensated for springback.

The end result is a die face design that has allowance for springback already built in.
