Hello! You've made good progress anyway. Your pen tip test starts at 0.2mm, and there is still some paper visible in the first pixel in your pen tip width test, so that shows that your actual pen tip is less than 0.2mm.

So the first thing you can do is drop your pen tip size to 0.2, that will give each pixel more "depth", it allows more levels of darkness to be expressed. Alternatively, you could use a thicker pen for it.

The second thing would be to use a different pixel type. The scribble pixel is quite hard to get good results from - I've really only has success with it with a very small grid size, and with a thick pen configured with a thin pen tip!

The original (and still the best!) pixel style is the variable frequency square wave. That's what the pen tip test uses.

Good luck!
