The EC Open Access policies and ERC Guidelines ask for either the final manuscript or the published version of the article to be made available for Open Access. Most deposited versions are the author's final version - the version after peer-review, after revision and checking - that is, the version sent to the publisher for printing. Some publishers allow the use of the final PDF file which contains their layout and style of font - in which case the versions are identical. Otherwise, while the style of the font might be different, the text of the repository version is identical except for any minor copy-editing done by the publisher after it leaves the author's hands.
