What are the differences between dyeing and printing?

Dyeing: A dyeing process is an interaction between a dye and a fibre, as well as the movement of dye into the internal part of the fibre. Textile dyeing is the process of applying colour evenly on the textile (fibre, yarn, fabric, or even garment). Depending on the requirement, textile dyeing can take place in any stage of manufacturing of the textile.

Printing: It is the process of applying colour to fabric in definite patterns or designs. Textile printing can be called as the localized dyeing.
