I thought it best to start a new thread about this issue of "Re-Profiling" (Printing, then reading at later date)
I have been interested in printing the target then allowing the print to dry for a longer time such as hours or days, then reloading the print to complete the scan to create the profile.
Thanks for the help on the previous thread.
So it turns out the way to do it is pretty simple, it just requires patience and futzing.
1. First I printed the target, trimmed the print using a "razor-in-the-slot technique" then I let it sit for about 3-4 hours.
2. Next, I reloaded the print as a sheet. This required some patience and screwing around mainly as the canvas is a bit unwieldy and it was a "short-sheet". Perseverance and following the on-screen loading prompts finally got me there, and the sheet was loaded. Note: that I chose "Load Sheet" and chose the custom paper that I used to make the profile.
3. Once the sheet was successfully loaded, I went back into the profile utility in the color center and chose "create and install ICC profile" then selected the action: "scan ICC profiling chart and create ICC profile", un-checking "print ICC profiling chart".
4. The process started, but it took maybe 5 minutes for the photospectrometer to warm up or prepare. Once it did, it went ahead and created the profile.
So ultimately it is possible to print the profile and wait, then reload and and continue with the process. I assume it would be much easier to just print the profile on the roll, then unload the roll and wait for the desired amount of time, then reload the roll to then read the chart and profile.
The key is to reload the paper first before attempting to do anything further.
So hurray - it works - just a little slow and a little picky, but really sweet.
This post is for those who are befuddled about this technique - and thanks to everyone for the suggestions, advice.
