I don't have the measurement files around anymore as I did the tests when
the printers first came out, but on CGS 180 gr. semimatte, I found a very
small difference between measurements after 10 minutes(although important to
note that with a Spectroscan it is not possible to measure the entire
ECI2002 in 10 minutes), 1 hour, 4 hours, 1 day and 1 week. As you mention,
paper I think has a lot to do with it, but probably also ink control. To
get stability at such short times, I think is due to no extra ink getting
put down, as often happens with RGB drivers.
