Ahh, makes sense. Sorry for misunderstanding... had I thought about it a little harder I should've realized that.
:o(
They weren't able to print the measurement sheets today, due to the production schedule (we've been quite busy lately, thankfully!), so I generated a new, smaller test chart and instructed CTP to plate it one-up, dead center.

Absolutely! I discussed everything in detail with the head dayshift pressman, and I will be called out when he does the run. Hopefully tomorrow, but we'll see... I also told him to run as many makeready sheets as necessary, regardless of how it relates to our normal runs.
