Beauty is in the eye of the beholder they say, but what they don’t say is that colour is also in the eye of the beholder. But colour in a digital world (and in the real world) has many variations of each and every colour imaginable. Are dark blue and navy blue the same colour, and where does royal blue come into the equation? For printers, web designers, manufacturers and many industries that are responsible for reproducing exact colours for customers, there can be a lot of misunderstandings on what the correct colour is when discussing projects that involve very specific colour combinations. To better understand colours in the digital and print world, let’s first understand these basics. Another school of thought is that cyan, magenta, and yellow printing plates are carefully keyed, or aligned, with the key of the black key plate in four-color printing. The RGB colour model is what is known as an additive colour model in which red, blue and green colours are added together in various increments to create a large variety of colours. A colour in the RGB colour model is described by indicating how much of each of the red, green, and blue is included. The colour is expressed as an RGB triplet ( r, g, b ), each component of which can vary from zero to a defined maximum value. Pantone colours are also known as spot colours and the Pantone Matching System or PMS. All colour in these devices is made up of a mix of the 3 colours and then the intensity of each of these colours. The Pantone system also allows for many special colours to be produced, such as metallics and fluorescents. Each colour scheme distorts the final artwork output. Let’s put this into something of more value after all a picture is worth a 1000 words. Print this on a couple of different colour printers and see the results. So what you see on screen or in your emailed proofs of colours for your project don’t necessarily show the true final colour output once printed. Likewise what your home or office printer prints will probably not be 100% the same as the final digital or litho print.
