saving in photoshop to .pdf

[Dava]

hi,

i am having some problems in photoshop, when i am saving to .pdf format its showing a white bar across some of the text.

am i doing something wrong when saving?

i untick the optimize for web viewing and saving it in full quality with no down sampling

where do i turn that off? inside photoshop or the pdf reader?
