Colour printing techniques and challenges

As is indicated by the name colour printing is the technique of reproducing an image or any text in colour. This technology has made the earlier existent technology of black and white printing or monochrome printing completely obsolete. It seems strange now that the so simple sounding basic principle of colour photography was not made use of until some recent time. It makes use of the fundamental colour mixing techniques which we are taught in kindergarten probably. The technique is that the three primary colours, that is, red, green and blue when mixed in equal amounts, create the perception of white. By further varying their compositions and creating different permutations and combinations all other colours can be created as well. As was taught to us in the lower classes, by mixing any two primary colours, a secondary colour is obtained. For example, a mixture of red and blue creates magenta, a combination of red and green leads to the formation of yellow and the combination of green and blue makes up the calm and serene looking cyan.
The passage of time has seen the evolution of various colour printing techniques. Industrial printing in case of mass scale requirements is also done these days. In fact, we have taken colour printing for granted, considering the way it has smoothly blended into our daily routine. Pick up any book or magazine around you. I doubt if you will find any of them in a plain black and white print. Leave alone books and magazines, step into your bathroom, even the toothpaste you use has a coloured tube. In fact run around your eyes in your vicinity. All you will find in your vicinity is a plethora of colours. Different kinds of printing techniques go into manufacturing these colour printed covers.
One popular technique is that of process printing which is also referred to as a four colour process. This kind of printing procedure makes use of four coloured inks. These four colours are cyan, yellow, magenta and black. The inks used are translucent in nature that means that they are not completely transparent. When two of these inks overlap on paper, a primary colour is obtained. Another emerging technique of colour printing is a six colour process printing which in addition to the four colours mentioned above, makes use of two additional colours, that is, orange and green. This enlarges the available colour palette.
These are not the only available printing processes but colour printing can also be done with a single colour ink. It can also make use of multiple inks out of which none is primary in nature. When the number of colour inks used is minimum and limited, and specific colours other than the basic primary colours are used in the printing process, it is known as spot colour printing.
Whatever the technique of imprinting colours on an otherwise blank paper be, it is beyond debate that colour printing has today captured the entire market and advertising space.
