Hi, Susie, I have some of the new SU ink pads and have had some problems with the "spongy" pads that SU has now been using. I know what you mean, and it's been frustrating for me as well. What I've learned (to some extent) is to not push the stamp into the ink pad too much, especially not as much to get it foaming. It shouldn't be doing that. I often will turn my stamp over and lightly tap the ink pad on it and then look at the stamp to see the coverage (in order to see whether it needs more tapping). I hope that helps, but there is a section in the Forum for questions about this.
Here's a direct link to it. Just click on "here." If you don't see a thread addressing your problem, you can start a "New Post" like you did here and ask a question. I believe you will get some help. Hope that helps. Hugs!
