Sounds good. My only concern is the longevity of the profile for a public printer. I will be sure to ask them if they intend to change papers soon or inks, but how reliable are the Epson profiles over time when the printer is used every day like this?
Dan, good questions. If they have a policy of using only Epson K3 inks, then I believe one can count on stable performance from one batch to the next. If they use 3rd party inks and change suppliers periodically, each time this happens a new profile would be recommended. Likewise and for sure if they were to change papers. The profile is only "accurate" for the equipment and materials used in printing the patches. Printer performance can drfit over time, but the 7800 has a built-in linearization technology I believe used with the ColorBurst RIP. Hence depending on how the lab maintains the printer, this may not be a factor significantly impairing profile performance over time. By the way, this printer model is now discontinued, so another question is for how long your lab will be using it before they up-grade. Sounds to me like you need to have a conversation with the lab asking them these questions and see what they tell you. Then you'll know whether going this route will be useful.
