Processes for the manufacture or reproduction of printing surfaces
Printing machines or presses
Printing plates or foils; Materials therefor
Definition statement
This subclass/group covers:

Substrates for printing plates or foils.

Treatment of such plates or foils.

{made of aluminium or aluminium alloys or having such surface layers (B41N 1/086 takes precedence) }
Informative references
Attention is drawn to the following places, which may be of interest for search:
Alloys based on aluminium as such
Stencils; Stencil materials; Carriers therefor (stencilling apparatus for office or other commercial use B41L 13/00)
Informative references
Attention is drawn to the following places, which may be of interest for search:
Forme preparation for stencil-printing or silk-screen printing
{characterised by the adhesive means}
Definition statement
This subclass/group covers:

Stencils, stencil materials or carriers therefor, wherein the adhesive means is between different layers.

Preparing for use and conserving printing surfaces
Definition statement
This subclass/group covers:

Pre-treatment of printing plates.

After-treatment of printing plates.

Treatment of both imaged and non-imaged printing plates.

{Cleaning, washing, rinsing or reclaiming of printing formes other than intaglio formes (B41N 3/06 takes precedence) }
Definition statement
This subclass/group covers:

The regeneration of printing plates.

Chemical or electrical pretreatment
Relationship between large subject matter areas

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.

Damping; Neutralising or similar differentiation treatments for lithographic printing formes; { Gumming or finishing solutions, fountain solutions, correction or deletion fluids, or on-press development (treatment of materials containing silver salts G03F7/06L; developers per se for processing photosensitive materials G03F 7/32) }
Definition statement
This subclass/group covers:

Developing with dampening water, also the composition of the dampening liquids.

The compositions of fountain solutions and gumming solutions.

Special rules of classification within this group

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.).

Special rules of classification within this group

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.).
