There is much more to forming an image in inkjet printing than simply positioning ink droplets on a receiver.
Liquid ink interacts physically and chemically with the fibers of the receiving medium.
The relationship between the perceived color image depends on the dynamics of how ink droplets are deposited, and on how the receiver incorporates the dyes in the inks. For example, based on drop-spreading models, we can derive simple design equations to calculate the required drop volume for a given print resolution for both coated and uncoated media.
