The anilox roller is a key component in flexographic printing.

It is responsible for transferring ink from the ink fountain to the printing plate.

The anilox roller is made of a metal core with a ceramic or steel coating that is engraved with a pattern of tiny cells. The size and shape of the cells determine the amount of ink that is transferred to the printing plate.

The anilox roller rotates in contact with the printing plate.

As the cells on the anilox roller pass over the printing plate, they transfer ink to the plate's surface. The amount of ink that is transferred is determined by the volume of the cells and the speed at which the anilox roller is rotating.

The anilox roller must be precisely engraved in order to ensure that the correct amount of ink is transferred to the printing plate.

If the cells are too large, too much ink will be transferred to the plate and the print will be too dark. If the cells are too small, too little ink will be transferred to the plate and the print will be too light.

The anilox roller is a critical component in flexographic printing. It plays a key role in determining the quality of the printed image.
