Ink is defined as a colored liquid used for writing and reading. Ink is the basis for daily functionality, and communication. Ink makes up homework, literature, business transactions. The issue however is, that ink oftentimes goes unnoticed. Often, people don’t realize that many important things to them consist of ink. This is because ink is not large, and it does not stand out, it just appears. Ink is simply something that is there and costly to replace.The history of ink dates back considerably, evolving over the ages into what it today
Ink manufactured for writing originated in Egypt and China originally dating back to around 2500 BC. This ink was composed of soot bound together with gums. This paste was formed into rods and dried before being mixed with water immediately before use. Ink of this time was only used for handwriting. Printing would then be created by the Chinese in 3000 BC. The invention of the writing brush made from hair is attributed to General Meng Tien of China. This allowed writing to be done on silk rather than with bamboo pens on strips of bamboo. Bamboo is heavy, bulky and awkward, but for all its virtues, silk is expensive. They used a mixture of coloured earth, soot and plant matter for pigments, again mixed with gums for a binder. Actual printing consisted of ink being drawn onto moveable slabs outlined with letters and signs. Then in 1440, when Johannes Gutenberg invented the first printing press with moveable type, was beginning to be made of soot bound with either linseed oil or varnish, materials extremely similar to those that are used in ink today. Following this in 1772 colored ink was introduced, however, the drying agents for colored ink would not be introduced until the nineteenth century....

Once the varnish is created, pigment dispersal occurs.This is when the pigment particles clump together. These clumps must be broken up and the pigment dispersed evenly through the resin. There are three main types of equipment used to do this. Shortly after dispersal, ink is then created.
The last step is the printing process. Printing is usually done using four different colours of ink: cyan, magenta, yellow and black. Theses subtractive colours are chosen because by 'overprinting' these inks, all other colors imaginable can be formed. For example, red is produced by overprinting yellow and magenta, as the yellow absorbs the blue light and magenta absorbs the green light, leaving behind pure red light. Black ink is used because although in theory cyan, magenta and yellow should add together to give black, they actually produce brown.
