The blue line has been given 'trapping' – specifically the 'spread' version. This made its outer edges slightly larger so that if there was some misregistration it would still cover enough to prevent showing a sliver of unprinted paper.<br />The Royal Mail's explanation of it being due to varying heat in the printing locations sounds like 'Chinese Whispers' to me; something incorrectly repeated by someone who doesn't really understand the process. The actual artwork production method in the last example is clearly one that uses trapping. Otherwise, the white text in the bar (the word "STATION") would fill in whenever the print started to swell. Nope, this just isn't logical and it doesn't fit with anything I know about print production methods and behaviour – which is something I teach at university.Keith Martinhttp://panoramaphotographer.comnoreply@blogger.comtag:blogger.com,1999:blog-61379575088648114.post-19594815469387865492013-02-23T09:39:06.541+00:002013-02-23T09:39:06.541+00:00"In which case:
