I'm doing a big print that will take a few days to complete. Instead of cleaning the screens after each use I decided to try refrigerating the screens with the ink still on them. I've heard of many successes with this on Flickr.
The next day I tried to print and could not get a clear print. My solid coverage now had splotches. The ink had dried and clogged the screen in some areas. After I cleaned the screen, I was left with clogged areas. You can see them in the picture below.
I'm hoping that when I print again I won't have any problems. Unfortunately, those clogged looking spots in the pic, that's where it was splotchy on my print.
Conclusion: I will not refrigerate my screens with ink again! No more shortcuts. The cleaning process is tedious, but well worth it.
UPDATE: I tried reprinting and it is definitely a clog. I printed as much as I could and hand painted the areas that wouldn't print.
