Problem in exporting to pdf in photoshop cs6

i need to export a label for printing and i have no contact with the printer nor will i. When i export a label to pdf via Adobe photoshop Cs6 i get nice and crisp text but there's an image that's so important and it renders in a bad resolution

but when i save it as tiff it renders fine but i need that pdf because i need the text to look crisp and clean so what can i do?

PDF settings: i saved it as a copy with no editing capabilities, using press quality and high image quality, and in the output i set the image quality to high
