In April, 2017, the customer was newly engaged in the printing industry and imported some print machines. He bought a container of self-adhesive vinyl from us. After receiving the goods, he reported that some products had blurred patterns after printing. Our salesman and technical department helped customers adjust the ink and printer parameters, explained the application scenarios and precautions in detail, and finally helped customers solve their problems. Now, the boss is one of our long-term cooperative customers.
