Common ways to customize patterns on product surfaces include screen printing, pad printing, UV printing, laser engraving and other processes. Customized surface patterns are a key process to enhance product value. Their functions include accurate information transmission (functional identification), brand enhancement and product identification (commercial value), functional guidance and operation optimization (human-computer interaction), surface decoration and texture enhancement (aesthetic value). They are widely used in consumer electronics, automotive parts, industrial equipment, home appliances and other fields.
