Essentially, editing is a process where the copy (the words you want to print or publish) is made ready for publication. It is something that needs to happen before you are ready to determine the layout for the text so that major changes to the text can be made – if required.
Editing will ensure smooth-flowing, accessible and consistent text – without compromising your voice or budget. It takes skill and experience to look at a text with a holistic view, right from the tone of voice to layout for publication. Investing in good, clear communication from the outset will save time and reputation.
There are lots of different kinds of editing, but really the most important thing is that we talk about what you need. The rest you can leave up to me.
