Digital BW, The Print

Aaron

Be careful with the food sealer. I think it has way too much vacuum. 
I placed my MIS UT inkset in a bag to keep them from drying out, 
intending to leave them only a few days and when drawing the air out 
with a straw - ink began to run out of the cartridges. Now I have a 
huge mess inside the bag. Trying to decide whether to write it off 
or clean them up.

I had thought of using the sealer earlier - sure glad I didn't do 
it.
