After hours of struggling with a recalcitrant poly-litho plate first drawn with sharpie (then cleaned & redrawn with ballpoint) it is a treat to work with another plate (shown above left) that inks cleanly! It gives me hope.
I will abandon the original Circles plate (shown in an earlier post), and perhaps create a new plate based on that design. Above you can see the a plate that works (shown at left), one print from this as scanned, plus one at right digitally enhanced for darker stronger lines. I have already added more to this plate for the next print round!
But here the fine point ballpoint lines are so delicate and the prints lack impact and strength. Much more work is needed!
