Have just got a new laptop and running cs5 on all but indesign which is cs3. I have a piece of artwork which has drop shadow and when I make a pdf on my old machine the shadow is fine and everything else but when making a pdf of the same artwork running cs3 on the new laptop which is a macbook pro intel i7 running lion I have issues with the drop shadow which is looking muddy and the text box background is showing asa tint! Have tried changing transparency flattener etc to no avail but the prob does go away when saving a as adobe 4 pdf 1.3 instead of adobe 5. The pdf looks fine apart from thin white keylines around the text boxes! Am missing something here but dont know what! Help!
How are you viewing this? Is overprint preview turned on in the viewer?
Sounds like you’re using Preview on your Mac instead of Acrobat.
Preview can’t handle advanced PDFs.
Er...um..what a dopey beggar I am ! Of course that's what it is and should have realised but of course go raging about and asking here instead of just thinking about it abit! Apologies for wasting your time and humble thankyou for replying.
