**Definition:** This place covers:

Machines or presses always include a fixed or static printing form, usually a printing plate, carrying a graphical and/or alphanumerical design forming the printing image,

after applying ink on the surface of said printing form, said inked image is applied by contact pressure onto the surface of a substrate which will form the printed matter,

machines or presses as a whole as well as all parts, details, objects and controls specifically adapted for use in such machines, e.g. drying, dampening, heating, cooling, cleaning, air blowing and suction devices,

feeding and/or handling of substrates to be printed upon is covered from the in-feed device through the whole machine down to the delivery device,

auxiliary folding, cutting, collecting and depositing specifically adapted for printing machines or presses in covered by B41F13/54 - B41F13/70 ,

machines or apparatus for printing operations in combination with other operations, e.g. embossing, are covered by B41F19/00 ,

machines or apparatus for printing operations in combination with perforating operations are covered by B41G7/00 .
