Dri-Offset Rotary Label Printing Machine

The dri-offset rotary label printing machine consists of four sections: unwind, printing, drying and rewind section.

The printing section of the offset rotary label printing machine is different from the flexographic label printing machine. Take the four-color offset rotary printing press for example, there are four ink fountains near which are four printing plate cylinders. The printing plates are adhered to them and their number is decided by the quantity of colors to be printed. The ink is transferred from the ink roller to plate, then to the rubber blanket on offset cylinder. The image is transferred to the surface of ribbon when it passes through the offset cylinder and impression cylinder.

The dri-offset rotary label printing machine has a simple dryer and an additional dryer is needed for multi-color and complex image printing.

Minghui provides common offset printing presses and numerical control offset printing machines.

The common offset label printing machine features a fixed printing length of 394mm and it is the length the ribbon goes around the machine. If the length of label that customer need to print is 49.25mm, the common offset label printing machine can print 8 labels in a round. If the label length is 50mm, 7 labels can be printed with extra blank space on the ribbon. In this case, customers can choose the numerical control offset printing machine to automatically adjust the printing length, eliminate the blank part and reduce material waste.
