Have any friends who work in the carton factory taught you some experience?

At present, there are two common printing methods in carton factory. One is "watermark", that is, the patterns and characters are printed directly on the pre-made cardboard. The other is pre-printing, that is, "offset printing" or "gravure printing" is printed on carton paper, and then it is bonded with single-layer corrugated paper. The host didn't say clearly what kind of printing it was.

Watermark: short for ink printing. The machine used is called an ink printing machine. It can be said that this machine is specially produced for carton printing. The operation method is similar to what several people upstairs said. First get the printing plate according to the product to be printed, then install the printing plate, install the printing plate on the machine, then adjust the ink, mix the inks of various colors evenly, and put the ink on the machine according to the color printed by the printing plate. Then try it out, take a piece of cardboard to see the printing rules and ink color difference, and then debug it to an ideal state to start printing.

The operation steps of "watermark" in preprinting are similar to those of "offset printing" and "gravure printing", but the two methods are quite different and not a machine. The details are different in more than one sentence. Printing can't be learned in a day or two, and you will know what printing is all about in a little bit.

As the upstairs said, printing must be cautious and responsible.
