ABSTRACT:
When spot printing is made by opposed blanket cylinders for spot printing that are disposed on one of a pair of blanket cylinders disposed to oppose each other in a rotary press, the present invention discloses a spot printing method characterized in that a suitable number (more than two) of blankets are selected from inside the range of division width obtained by dividing the full width range of the blanket cylinder for spot printing into a suitable number (more than two) of widths and are then fitted to the blanket cylinder for spot printing, and printing is then made by the blanket cylinder for spot printing.
The present invention discloses also a blanket cylinder for spot printing which comprises a suitable number (more than two) of blankets of a width within the range of division width obtained by dividing the full width range of a blanket cylinder; and blanket fitting devices operative independently of one another within the range of division obtained by dividing the full width range of the blanket cylinder.
