Achatmarmor: "Agate marble", mimicking the appearance of stone by sprinkling color onto a wet sheet and allowing the sprinkles to spread into irregular, diffuse spots. The quintessential composition notebook pattern is based on this design.

Brocade: Also called "Dutch Gilt", metallic designs are embossed onto a single or multi-color surface-colored paper.

Bronzefirnis: "Bronze varnish" is similar to Brocade papers, but this older technique has printed metallic designs which are flat rather than embossed. 

Buntpapier: A general term for papers which have been decorated after being pulled from the vat, often exclusive of vat-colored papers 

Colorway: Any of a number of color combinations in which a given pattern or design exists—see 25.046/25.032 or 23.004/26.040 as examples of the same pattern in different colorways.

Embossed: Distinct from brocade papers impressed by hand with engraved metal blocks, embossed papers are generally machine-decorated papers impressed with engraved metal cylinders. 

Full Paper Binding: A book with one or more pieces of paper covering the spine and boards, be they wooden or paper-based.

Gustavmarmor: Similar to Achatmarmor, this is a sprinkling technique that uses chemicals to produce halos of a secondary color surrounding diffuse spots.

Irispapier: A surface coloring technique wherein stripes of color are blended together with a series of dry brushes to create soft gradient or ombré effects.

Kiebitz: "Lapwing" or "Plover" is a sprinkled decoration, traditionally black specks over a brown surface-coloring, which resembles the eggs of the bird for which it's named.

Limp Paper Binding: A single piece of thick paper, with or without turn-ins or secondary decorative covering, is used as the book covering, and sewing supports are either laced in or adhered. Differs from a wrapper in weight and method of textblock attachment.

Negative/Positive Designs: This describes whether the major shapes or figures in a printed sheet are made up of mostly inked or un-inked spaces. Negative designs have been carved out of the block, and only the background is printed; positive designs have the background carved away. It is possible, of course, for both techniques to be used in the same block: in 24.001, the green impression creates positive leaves and stems along with negative floral shapes which are filled in with the red impression.

Rieselpapier: "Trickle paper", wherein liquid colors are applied to a vertically angled sheet to capture the trails of flowing liquid; in the c. 1840 Aschaffenburg sample book, several examples are labelled as "Markgrafenpapier" [Margrave's paper].

Surface-colored: Paper which is colored after the sheet is formed; fibers are generally colored only on the surface of the sheet, and uncolored fibers may be visible on the reverse side or in abraded areas.

Tupfpapier: "Dabbed paper", wherein colored paste is sponged directly onto a plain or surface-colored paper.

Vat-dyed: Paper which is colored during the papermaking process and thus not technically "decorated". Fibers are colored all the way through the sheet.

Wrapper: A single piece of paper, often thin or text weight, is used as the book covering. Often stitched through the side of the textblock or adhered, either along the spine only or to supporting endleaves.

Wurzelmarmor: "Root marble", mimicking the appearance of root- or tree-marbled leather bindings which are created by dripping acids over wet leather to create dark swirling designs.
