I have this from time to time, although never with monoprints, only collagraph. I’ve never been sure what causes it, but having fairly fluid ink does help.
I’ve also seen it suggested for monoprints that smearing the plate with a fine film of washing up liquid before applying the ink helps to ensure a clean release. I’ve never tried this though.

It used to happen a lot when I used Fabriano paper. I now use Somerset 300 which is less dense and moulds to the texture of the plate better. The Fabriano was quite smooth so perhaps there was a sort of ‘suction’ effect at work that doesn’t happen with the rougher Somerset, especially if the pressure was to high.

Soaking the paper well, then drying it evenly also helps. The soaking seems to aid flexibility, while the even drying ensures even bonding across the plate.

I’ve never used Zerkall so can’t comment.

Too much pressure can also be an issue, especially if the inks are a litle sticky. I’ve noticed too that some inks are naturally stiffer than others so your observation of some colours being worse than others may relate to that.

It doesn’t happen too often for me now which I put down to fairly free flowing inks, getting the dampness of the paper right and avoiding very humid weather.

For collagraphs temperature and humidity seem to be a factor, perhaps by softening the protective varnish.

you should change the ink properties, by adding a tack reducer. (tack = stickeness of the ink)

Most watercolor painters have encountered the disappointment of their paper clasping making the paint stream wherever with the exception of where they need it to go. Stretching watercolor paper makes it stay level for the entire painting measure like a duplicate fob. The experience of painting on watercolor paper that stays entirely tight and level is disclosure to painters who have consistently battled with their paper.

It sounds like you’re encountering a tricky issue with your printmaking process. As you’re using oil-based inks and Zerkall paper, it might be a compatibility problem. It’s peculiar that cadmium red ink is causing more trouble. On another note, have you ever considered utilizing local SEO ranking services for your artwork? It could be an effective way to broaden your audience’s reach. Anyway, as for the paper problem, you might try testing different paper types to see if you get better results.
