Fabrics tend to stretch a lot. It hardly maintains a constant size or shape. This affects a designer since the colour of the design starts to merge with each other and thus becomes difficult to print. To overcome this problem and to make printing on t-shirts easy, the process of colour registration is used. This ensures that the colours are at the right place in relation to the other colours and do not mix with each other. However this technique needs to be done with care and by an expert who has mastered this skill. Any error in registration can make the design look shabby. They start looking misprinted and poorly aligned. Even a slight shift in the fabric can make the whole design messy and spoil the output of the final product.
The registration process happens during the t-shirt printing phase, however in order to increase the clarity and make it more accurate, the process can be carried out during the design phase too. This is called trapping. This process adds a light stroke to the colours so that the overlapping zone between colours is bare minimum. This makes a huge difference to the output of the product and they look cleaner.
In the screen printing process, the colours in the design is printed with a short interval between each colour. This lets the colour settle and spread marginally. If it is a very fine grained mesh it causes the colour to spread a lot which increases the chance of the details of the design to get lost. The main reason for the colour to spread is the tightness in the mesh of the screen which is being used to squeeze the ink. If the mesh is not tight enough then the ink penetrates through bigger blobs and causes more spreading.
