And after going back that same spot that didn’t mark, there’s no ink?

Paper was too slick. Those pens need friction to move the ball at the end of the point and transfer ink to the paper. If the ball doesn’t catch on the paper and move, no ink.

Also gel pens have thick ink so it doesn’t always come out at the same pace.

Ballpoint pens have a tiny little ball at the tip, and an ink reservoir that feeds down into the ball coating it and thereby delivering ink. If the ball is somehow stopped from moving, the ink can’t release.

Tiny imperfection in the ball can prevent it from smoothly rolling across a surface, which means it won’t write on that spot. The surface may also have tiny imperfections, or be too smooth in general, to write on with a ballpoint pen. Going back to a rough surface or approaching the area with a different angle might allow it to continue writing, but often you’re just SOL when it comes to ballpoint style pens.

They’re super convenient, don’t waste much ink, don’t dry out as readily, and provide a smoother writing experience, which is why they’re so prevalent among low-cost pens.

This happens to me too. Those pens are annoying if you’re left handed tbh. The nib always digs into the paper without putting down ink.
