Methods and Apparatus for Controlling Register Error

An electronic device comprising:

• a processor;
• a communication interface;
• a memory;
• and
• a bus;
• wherein the processor, the communication interface, and the memory communicate with each other through the bus;
• and
• the memory stores at least one executable instruction executed to cause the processor to:
• acquire a control volume and a register error of a current gravure unit at a first moment, the control volume indicating a set value of a rotational angular velocity when the gravure unit is controlled to operate;
• acquire a control volume of at least one previous gravure unit at the first moment, the previous gravure unit being located prior to the current gravure unit as per a printing sequence;
• predict, via an error prediction model, a register error of the current gravure unit at a second moment based on the control volume and the register error of the current gravure unit at the first moment, and the control volume of the at least one previous gravure unit at the first moment, to obtain a predicted register error of the current gravure unit at the second moment, the second moment following the first moment;
• and
• determine a control volume of the current gravure unit at the second moment based on the predicted register error of the current gravure unit at the second moment.
