We are so far into the digital age yet there is still a bit of confusion about CMYK (and RGB) colour models. I'll do an overview of the CMYK colour model and the affect on digital print it has. The biggest misconception is that a colour specified as CMYK percentages alone represents an actual colour. It would be wrong to accuse a digital printer for producing incorrect colour if the only thing you provided was a combination of CMYK percentages such as those seen in corporate identity manuals. Read on to find out why...
In previous articles, I covered how we control colour with software and hardware using design programs and the printers. There is another important piece of hardware too. It's a colour matching booth. Not a weird device that you climb inside and lock the door, but rather a station that has special fluorescent tubes that illuminate vertically mounted prints and proofs from above. The big problem to overcome with manual hardcopy matching of colour is the lighting conditions. There are so many different conditions, fluoresecent warm to cool tubes, halogen, daylight sunny and cloudy, incadescent blubs and now led lighting which all emit different colour. There is no easy solution but a good start is an industry standard, which just happens to be D50 or more commonly known as daylight.
Matching colours correctly; it is a process that happens behind the scenes. You might not realise how important it is and why we take it so seriously. A number of years ago I read an article which is a great way to describe why colour management so important. It's all about making toast!
