When gravure printing machineloading the plate, pay attention to the left and right sides of the plate. When the cone is clamped, it should not be too tight to prevent the copper plate roll from being cracked. If it is too loose, it will “escape the plate” when printing. The plate roller is mounted in accordance with the printing color sequence. The printing color sequence printed in the printing is gold and silver ink → black ink → original green → original yellow → original red → white ink. Just the opposite when printing: white ink → magenta ink → yellow ink → green ink → black ink → gold and silver ink.
