A Study of PMS-300C Logo

This PMS-300C case is an excellent example. I’ve followed the printing of this supplementary label on packaging for many years. What can we learn?

Summary:
– Not even the PMS book is the same reference as digital library (dE=2,16).
– PMS-300C is not achievable in normal CMYK (dE>4,62).
– ECG inks can reach it (dE=0,86).
– Spot inks can for sure reached it (dE=1.51).
– Process control is key for both process and spot ink printing.
– Different repros and printers can take different approach to color separations.
– Also printed spot inks can vary a lot (n=10; Ave=4,96; Min=1,51; Max=7,07; STD=2,075).
– Not all design colors need tight tolerances (dE<2,50).
– Brand owners accept even large color variations (dE=14,30), based on color priority.
– There’s no reason to force using spot inks always.
– Some tight tolerances would create unnecessary waste, without having influence on sales function.

IMO, the color tolerances can vary by object priority, e.g.:
– Priority-1: dE00<2,5
– Priority-2: dE00<5,0
– Priority-3: dE00<10,0 (or more)

What do you think? Any surprises?
