Form 3- Time to Change the Tank?

Very simple…
How do you know when it is time to change the tank?

You’ll see damage/points on the flexible layer.

Fantasy is correct, you’ll see it, but also you may start to notice some diminished accuracy in the actual prints. That’s a good guide as well. This may start to happen longer after you see issues on the tank surface than you’d think, so that would probably be my default guide.

On the matt inside of the tank there are some clear areas of finished prints.
Is that normal or should we avoid printing at these places?
