(sorry to double post, it seems that I cannot edit my last one)
By the way, would it be possible that you upload a vectorized pdf (I mean with real text, background images, etc...) instead of the "bitmap" pdf ? I imagine that you composed your document with a background texture, then added thematic images, and then, postcrip fronts text, and finally created a single bitmap image file ?
If you could share a vector/composed PDF, this way it would be possible to modify it by ourselves, remove background for printer friendly usage, translate it in another language, etc...
thank you!
