Colorful disc surface offset production specifications

Disk printing has its own special requirements. If the electronic document or film used for the surface printing does not meet the printing specifications, it may cause delays in the completion of the order. Therefore, ensuring that the print preparation materials correctly meet the printing specifications is the key to ensuring the expected delivery date. Customers should confirm that their panel designers are fully familiar with these related printing specifications to provide electronic documents or films in the correct format.

Therefore, computer-printed color inkjet samples do not provide the correct color-tracking reference for optical disc printing. Usually, customers are required to provide 3 copies of proofing.
