Grad 4: represents the increased density that can be achieved by adding
Black to CMY (also referred to as the “skeletal Black”). The shape of the
curve reflects where Black begins and ends and the slope of its ramp in
between. The endpoint of the Grad 4 curve represents the total reproduction
density of all four inks (generally ±2.0 for coated stock). The area in
between Grad 4 and Grad 3 curves represents the skeletal Black:
By pulling the nodes of Grad 4 down to meet Grad 3,
the Black is eliminated in the density range where the curves meet:
