Sorry, I think did not express it correctly, what I meant is that looking to the puzzles with the same scale: for instance, if you use the scale 100% with the Adobe Reader you do not see the dots in any of the 250 puzzles while if you go to a higher scale, i.e. 129%, then the first 200 puzzles do not show the dots but you see the dots and the continuous lines "overlapped" in puzzles 201-250, if you now increase again the scale to 150% then you have the continuous lines and the dots in all puzzles, is it not possible to suppress the dots "under" the continuous lines in all borders of the cages for any "scaling"? (that was what I tried to suggest, no problem with the exterior borders of the full puzzle or with the borders of the 3x3 boxes, these always show a continuous line). Reedit: Amplifying to 800% it is observed a very slim continuous line and over that a series of much wider dots; I understand that most killer's designers use only dots for the borders of cages but I think it's not really necessary and it looks better with only the continuous lines.
