Cyanotype blue ground, white line drawings, dimension callouts, title block panel
A starting grammar for a website in Blueprint: one matte sheet of Prussian blue, white line in a fixed width series, a frame and a ruled title block that hold real information, and nothing that measures nothing.

Section B–B
Plain single-stroke letters; capitals for titles; one or two sizes.
DRAWING NO. · REV · OWNER
Frame, grid references, centring marks, views, title block lower right.
One series, 4 : 2 : 1. Square corners, no ornament.
A projected view; every callout measures something.
The record documents interface conventions for Blueprint. These four components are contemporary builds on those conventions, not historical artefacts.
A drawing does not animate.
Hover the buttons: the swap to a bleached patch is instant.
Matte, grained, continuous tone. A correction is bleached out and leaves a white mark.

A drawing that will be built from has no room for interpretation.
Every line weight, callout and panel exists so that a reader in another workshop can reconstruct the object exactly, and the blueprint is the quick, cheap contact copy that carries the drawing there: white line on Prussian blue is the chemistry of that copy, not a style.
White line work reversed out of a saturated cyanotype-blue ground, with projected views, dimension callouts and a ruled title block: the conventions of the engineering drawing it reproduces. The blue is the chemistry of the contact print.
The diagnostic condition is that the apparatus is load-bearing: the title block identifies the document and the callouts measure the object.

Composition: sheet frame, corner title block, grid refs.
A 1911 engineering manual prescribes, for working drawings (which blueprints reproduce), rapid single-stroke lettering, vertical or inclined with inclined preferred, and titles in freehand single-stroke capitals.
A 1911 engineering manual condemned ruled geometrical and block letters.
Large offices sometimes had title forms printed in type on the tracing cloth, which then reproduced in the print.
Later standards list templates among lettering techniques and require lettering fit for copying processes.
A plain single-stroke letter, capitals for titles, at one or two sizes: the freehand lettering of the working drawings blueprints reproduce. Ruled block letters were condemned in the period; templates belong to later standards.
Colour: cyanotype blue, white line.
White line work reversed out of a saturated Prussian-blue ground. The colour is not a palette choice: the cyanotype process produces exactly this, and a blueprint in another colour is a drawing that is not a blueprint.

The blueprint is a single-layer print: Prussian-blue pigment in the fibres of uncoated paper or cloth, with no binder layer.
The surface is extremely matte, the paper or cloth texture is visible and usually rough, and the blue ground has continuous tone.
The verso is usually the colour of the support (white or off-white).
A 1911 manual notes that prints from some papers need more exposure and look mottled, plainly showing texture and watermarks.
Supports included paper, linen (which shrank), imitation vellum and later polyester film.
Prints were made quickly and cheaply for an ephemeral purpose, not long-term stability; the 1911 manual says the sensitised material darkens and spoils with age or exposure to light or air; faded blueprints can regain substantial density in dark storage.
Corrections were made by bleaching the blue with an alkaline solution, which leaves white marks on the ground.
A 1911 manual instructs that working drawings be laid out with a border and says the title is usually boxed in the lower right corner; blueprints reproduced these.
Current standards put the title block bottom right on A0 to A3 sheets inside a 0.7 mm frame, and define its fields (legal owner, identification number, revision index).
The drafting practice blueprints reproduced rejected ornament: intricate border corners, elaborate north points and ornamental titles were condemned as a waste of time and in bad taste.
The only recurring non-content marks found are functional sheet marks such as the frame and reproduction centring marks.
A blueprint is a flat, single-layer sheet, usually large, stored flat or rolled.
Rank by line weight, as the engineering drawing it reproduces does: outlines wide, hidden detail dashed, dimension and witness lines narrow. The print carries the drawing's widths; it adds none of its own.
Form / motif / surface / technique: cyanotype reproduction.
A ruled title block in the sheet corner carries drawing number, revision and owner. For A0-A3 sheets the standard places it bottom right.

Scope: The visual register of the cyanotype blueprint, an 1842 reproduction process: white line reversed out of Prussian blue, as Aesthetary's drawing language; the title block and dimension callouts are unverified drafting conventions we add.
Neither is a free hand: an area research has not reached is not permission to decide on the language’s behalf.

Engineering Drawing AESTHETIC
Blueprint is not Engineering Drawing's parent, nor its child. A blueprint is a reproduction of an engineering drawing made by a contact print process, and engineering drawings are made to suit several copying processes (diazo, microfilm, telefax). The two share the drawing's conventions (projected views, title block, dimensions); Engineering Drawing is the drawing, Blueprint the cyanotype print of it.
Cartographic AESTHETIC
An object to be built versus terrain to be traversed.
