Overprint Preview - It Makes Things Disappear
Today I had a call from one of my clients saying that a print job he had just had done has come out wrong. The word "Pure" should should have been printed all red but instead came out all black and red, almost as if the top item had disappeared.

I had no idea why this was but it's something to do with the use of "Overprint". A quick bit of Googling turned up this great article on it at Creative Pro.
So here's a quick tip: If you are working on artwork that hasn't been created by you from scratch, do a quick overprint preview to see where your colours might be falling down.
How strange! Great tip though, thanks…. Logged….

Of course I’ll have forgotten that by the time it happens to me
September 15th, 2006 at 7:57 pmLuckily the proof that the client had signed off had the red in place so when the print shop tried to say it wasn’t their fault they didn’t really have a leg to stand on. I’m not sure why the artwork I was working from would have used overprint fills though - it served no purpose.
