copy-editing
...................................................................................................................
When your work is at the final stage when you cant make it any better, and there are no more changes to be made then it is ready for copy-editing.
Copy-editing involves careful word-by-word checking of grammar, punctuation, style, inconsistencies, meaning and tone. The editor also repairs phrases and words that are odd, incorrectly used or ambiguous.
The editor will check cross-references, indexes, tables of contents, chapter headings, footers, numbering and flow. Part of the job involves directing the designer how to set like elements, approach the layout, and how to handle the artwork, drawings and graphics.
After editing, the final product is much improved and better presented than the writer ever expected.
proofreading
...................................................................................................................
This stage of editing is the very last time the manuscript is edited, and is an additional once-over before the printer produces thousands of copies of the document.
Proofreading is best undertaken after both editing and author corrections have been incorporated, to catch noticeable errors. It is often undertaken at galley proof stage, where the mock-up from the designer is checked to see how it looks in page layout.
More errors will be picked up in proofreading, and it is important that this stage is not overlooked. Details that ten readers have missed are often picked up here especially the ones readers will notice.
Some products are not proofread (or even edited, for that matter). The client usually finds that the product looks and reads poorly, they are embarrassed by mistakes, and regret the waste of money.
