Abstract
Described is a printing system including a first array of ink ejection elements formed on a first substrate surface for ejecting droplets of a first ink, a second array of ink ejection elements formed on a second substrate surface for ejecting droplets of a second ink, a memory element associated with the first and second arrays of ink ejection elements contains parameters that relate droplet ejection characteristics of the first and second array of ink ejection elements. The droplet ejection characteristics may contain ink ejection alignment data that enables the calculation of the relative alignment between the first and second arrays of ink ejection elements such that droplets of the first ink can be effectively aligned with droplets of the second ink. Also, ink droplet volume data enables the calculation of the relative drop volume between the first and second arrays of ink ejection elements such that the printing system can provide hue control.
