Linguistic Sign-Off (LSO)
You have my word (of translator)
Good communication also implies a proper use of the space. Once the content has been reviewed and proofread and it has a proper layout, the next step is to check the text from a visual point of view in order to assure that all fits properly: tabs, slashes, split words, etc.
An LSO means the final go-ahead of a project. It confirms that the text fulfills its aim and that its layout is correct.
