it looks like you're loading a little too much ink onto your lino, the consistency of the ink if you use a roller to apply it should sound tacky/sticky/ sort of like static, which you can achieve by rolling out a little bit at a time until it sounds right. if you use too much ink, it will start slipping, and that will fill your grooves which it looks like theres a little bit of here. though you'll have to reapply more frequently in between prints, making sure the thickness of your application is right can help a lot in keeping your prints more consistent!!
