1) Don't over spray, work in one area and move to the next one and go back if you want to spray more, it will dry pretty fast if you use alcohol instead of water.
2) Protect your table.
3) Count how many drops you are pudding in your spritzer in case you need to refill you can get the same color if you use same amount of ink drops.
4) and one more thing shake your spritzer, to mix the alcohol with the ink.
I hope it helps here is a video for more details. thanks for watching :D
