A typesetter regularly sends me manuscripts (300-400 pages long), which she has created in Quark or Pagemaker (sorry, I don't know which) and converted to pdf (sorry, again I don't know which package she uses). When I look at the pdf on screen or print it, there is some very odd spacing - words stretched out, two characters very close together ... that sort of thing. If I convert the pdf to Word, there are physical spaces between some characters in words - so very many that it is impossible to use spellcheck or search and replace. The typesetter says not to worry about this as it is fine on her system and will print from Quark/Pagemaker OK. This isn't very satisfactory for me as I have the document to proofread and the odd spacing makes it difficult/more time consuming. My question is, though, why does this happen? I thought the whole point of pdf documents was that they picked up a document and stuck it down again in its exact form. I regularly convert Word documents to pdfs and do not have this problem, and I receive pdfs from other people which are spaced perfectly.
