What method to print local bright oil

One way to print glossy oil on the surface of a cassette is to burn a plate that prints bright oil and print bright oil like a printing ink. But doing so increases the cost of production.

For some hard-to-finish plates, the paper pad under the blanket corresponding to the paper tongue of the bond can be partially cut off, so that the printing pressure of that part is insufficient to transfer the light oil to the paper, so that no other Partial gloss oil printing is completed in the case of printing plates.
