Drop weights corresponding to drop weight patterns

A fluid ejection system comprising;

• a system controller;
• and
• a fluidic die comprising:
• a plurality of fluid actuators to cause ejection of fluid towards a target;
• an actuation data register to store actuation data that indicates each fluid actuator of the plurality of fluid actuators to actuate;
• and
• a plurality of registers to store respective different drop weight patterns, each drop weight pattern of the different drop weight patterns indicating a respective set of fluid actuators of the plurality of fluid actuators enabled for actuation, and a first drop weight pattern of the different drop weight patterns corresponding to a first drop weight, and a second drop weight pattern of the different drop weight patterns corresponding to a second drop weight different from the first drop weight.

A fluid ejection device comprising:

• a plurality of fluid actuators to cause ejection of fluid towards a target;
• an actuation data register to store actuation data that indicates each fluid actuator of the plurality of fluid actuators to actuate;
• a plurality of mask registers to store respective different drop weight patterns, each drop weight pattern of the different drop weight patterns indicating a respective set of fluid actuators of the plurality of fluid actuators enabled for actuation, and a first drop weight pattern of the different drop weight patterns corresponding to a first drop weight, and a second drop weight pattern of the different drop weight patterns corresponding to a second drop weight different from the first drop weight;
• a multiplexer to select a mask register of the plurality of mask registers;
• and
• an actuation controller to control actuation of a set of fluid actuators of the plurality of fluid actuators based on the actuation data in the actuation data register and the drop weight pattern in the selected mask register
