A quick search online will reward you with endless examples of typos. As you can see from the links below some are cringe-inducing, some are downright offensive and many can be pretty costly.
A 'typo' is a typographical error – usually a minor mistake in typing or printing - that can have major consequences. The very mention of the word sends a chill down the spine. At best they are embarrassing; at worst they suggest a lack of professionalism beyond the simple mistake in hand.
The harsh reality is that they occur, and maybe we shouldn’t obsess over them as much as we do. All you can do is your very best to catch them before you approve a job for print.
Here at Impact, we always advise our clients to never rely solely on Microsoft Word spell check and other predictive text facilities; always allow enough time to review the content of the proof and finally to get a “fresh pair of eyes” on the artwork before approving for print. We don’t claim to have a 100% record on typos, but we do have a system to avoid them where we regularly check artworks with our own team of proofreaders as well as working with consultants on larger projects. After all that, if the typo gets through, their(!) is very little can be done about it.
