This client required a colour and black & white version. So we created the first version in full colour to match the original and then using this we simply recoloured it into a single colour black version. You may notice we had to separate the C&P from the graphic behind otherwise it would appear all merged together and become unrecognizable.
Quite often our clients require an extra single colour black version for certain types of medium such as engraving or vinyl cutting for vehicle graphics as another example. We do charge a little extra for this if it needs to be edited slightly as in this example.
