It is not fully exposed.

However, that itself can be caused by various conditions. Emulsion being too thick. Emulsion not being dry all the way through, something that happens easier when the emulsion is too thick. A weak UV light source, which again is more of a problem if the emulsion is too thick.

Possible causes:
a) old/defective emulsion.
b) humid environment.
c) underexposure.
Personally, I prefer my screens a bit slimy on the squeegee side because they are easier to wash.
Then I dry them and post-expose to fully cure.
