The difference between printing oil and machine oil

Oil passing is one of the very important processes in printing. After printing, the printing factory will apply a sample layer of protective oil on the printed material to protect the ink from slight scratches, which also protects the paper. This type of protective oil is generally referred to as over oil. Generally, strict requirements are required. Oil passing machines can be used for oil passing, including gloss oil, matte oil, matte oil, vacuum oil, etc. The oil produced by oil passing machines is relatively thick and can reach the level of gloss glue. Generally, for exported products, oil passing machines are preferred.
