It is easy to become ‘blind’ to what is actually written, especially when you have been closely involved with a job and know what it ‘should’ say.
Proof reading is a skilled job requiring high levels of concentration, a detached viewpoint and a sceptical eye in order to seek out what is wrong rather than what is right! For instance often text is read backwards before reading it forwards to avoid being lulled by the sense of a paragraph in to missing spelling errors.
Every day our proofing team spots errors which could have been at least embarrassing and at most could render the printed job unusable. Often this is in work which was looked at by several people before the PDF was submitted!!
As part of our Pre-Print Check we proof read jobs and work hard to ensure that the printing we produce is perfect. Whilst this is not a guaranteed service it is rare that errors get past our proof readers!
