CPC Definition - Subclass B41N
This place covers:
- Printing plates or foils
- Materials for surfaces used in printing machines for printing, inking, damping, or the like.
- Preparing such surfaces for use and conserving them.
This place covers:
Substrates for printing plates or foils.
Treatment of such plates or foils.

Attention is drawn to the following places, which may be of interest for search:
Forme preparation for stencil-printing or silk-screen printing |
This place covers:
Stencils, stencil materials or carriers therefor, wherein the adhesive means is between different layers.
This place covers:
Pre-treatment of printing plates.
After-treatment of printing plates.
Treatment of both imaged and non-imaged printing plates.
This place covers:
The regeneration of printing plates.
Usually the hydrophilic coating of the substrate is classified in B41N 3/03 and its hierarchical lower subgroups (see the table in the definition statement of the subgroup B41C 1/10). However, if an application claims a conventional method for making lithographic printing plates having a highly unusual hydrophilic layer, then the appropriate classification entry is B41C 1/1016, since B41N 3/03 does not relate to the preparation of printing plates per se.
This place covers:
Developing with dampening water, also the composition of the dampening liquids.
The compositions of fountain solutions and gumming solutions.
This place covers:
- Mounting boards.
- Sleeves.
- Make-ready devices, e.g. underlays, overlays.
- Attaching by chemical means, e.g. vulcanising.
- Attaching the printing formes on the cylinder.
This place does not cover:
Devices for attaching printing elements or formes to supports (i.e. mechanical aspects of the fastenings as such) | |
Devices for attaching coverings or make-ready devices; Guiding devices for coverings (i.e. mechanical aspects of the fastenings as such) |
This place covers:
Shells for rollers of printing machines, which are not printing cylinders or blankets.
This place does not cover:
Damping rollers (i.e. mechanical aspects as such) | |
Construction of inking rollers |
When classifying in this group or in its subgroups and if the invention lies in a specific layer, an Indexing Code (a hierarchical subgroup of B41N 2207/00) shall be given to specify said layer (e.g. backlayer, intermediate layer, cover layer, etc.).
This place does not cover:
Transfer cylinders; Offset cylinders |
This place covers:
Inventions relating to e.g. monolayer blankets, blankets having a special support, blankets having a surface of specific smoothness, etc.
This place covers:
Multilayer printing blankets (two or more layers).
When classifying in this subgroup and if the invention lies in a specific layer, an Indexing Code (a hierarchical subgroup of B41N 2210/00) shall be given to specify said layer (e.g. backlayer, intermediate layer, cover layer, etc.).
This place covers:
Molded matrices or mats of papier-mâché or similar material for casting the stereotype printing plates from hot metal.
