Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of soft -proof press gloss oil mechanism, especially to a kind of soft -proof press with double group gloss oil machine mechanism. BACKGROUND

[0002] The printing machine is first to print the text and image into printing plate, install in printing machine, then by hand or printing machine the ink is applied to the place of printing plate with text and image, again directly or indirectly transfer to paper or other printing material, to copy the same printing product with printing plate;

[0003] In order to improve the preservation time of printed matter, usually in the rear section of printing will be set gloss roller, gloss oil is evenly applied to the surface of printed matter, so as to improve the preservation time of printed matter.
