Short answer - yes it drifts, but there is a standard to compare it to, and
if a lab cares about what they are doing, they will try to achieve that
standard. All color processes drift throughout the day, with high or low
usage. they have to be monitored and controlled. If a lab just says "hey,
it changes. Theres nothing I can do about it." then it's time to look for
another lab.
