Hello, I’m Alec from Fineline Print, and I’m back again to answer a question which frequently pops up in design circles about Black.
As strange as it may seem, there is more than one type of Black and I’m going to show you the difference and … how to use that knowledge in your design work.
In our Learning Centre Guide 'What is CMYK' we looked at the four Process Colours: Cyan, Magenta, Yellow and Black.
In this instance the Black in question is known as True Black and on large areas of coverage it can look a bit washed out. Grey almost.
But using the other Process Colours there is a way of achieving an even deeper Black. This we know as Rich Black.
The Rich Black you can see in the graphic above is made by adding Cyan, Magenta and Yellow to the ink mix in the following proportions: C-75% M-68% Y-67% K-90%
So, that’s all very interesting but how does it help you as a designer?
Well, here’s just two examples:
And here’s where not to use it:
Small areas of Black. Rich Black may misregister on very thin or small areas – and this applies to type as well.
Extra care should be taken when placing graphics with a Black background into areas of solid Rich Black.
If the Black in the graphic is True Black it will stand out like a sore thumb in the printed job.
Take great care to check because the differences between the two Blacks are not always easily spotted on screen but the effect, when printed, may be enough to ruin your job.
To avoid the situation altogether, it’s best to use graphics with a transparent background such as PNG and Vector files.
True Black and Rich Black mismatches in printed work can be really frustrating so I hope this quick run through will help you avoid the issues in your own design work.
But before you go …
