hi andrea,
zoom to a level of 6400% and you can give the answer yourself. this is
just the way acrobat's rip is interpreting your separator gfx.
you can try to remove the horizontal border lines (also too fine for
printing). additionaly you can use (slightly) alternating background
colors per line to emphasize the horizontal borders (like in exxel).
btw: very nice location (only sunlight is missing); please drop a note
when the final pdf is released :)
best wishes, peter
