A magnification tool (visor, lamp, glass, loupe, microscope etc..) 
should go a long way in troubleshooting the problem. Do the following;

1. Examine the printed artwork "nine ways to Sunday" using the above 
tool. If there are issues here then it's pointless proceeding with 
the exposure step.

2. Examine the developed board as above. If there are issues here 
then it's pointless proceeding with the etching step.

3. Examine the etched board as above.

Once you've determined where the problem lies then you can focus on 
its correction.
