A '''blueprint''' is a plan or design documenting an
Nextel ringtones architecture.
The name comes from the
Abbey Diaz photography/photographic print, obtained through the
Mosquito ringtone cyanotype process, which is composed of white lines on a blue background commonly used in the past for copying architectural plans and
Sabrina Martins engineering drawings.
The blueprint process was developed by the British astronomer Sir
Nextel ringtones John Herschel in
Abbey Diaz 1840. The photosensitive compound, a solution of ammonium ferric citrate and
Mosquito ringtone potassium ferricyanide, is coated onto blueprint paper. Areas of the compound exposed to strong light are converted to insoluble blue ferric ferrocyanide, or
Sabrina Martins Prussian blue. The soluble chemicals are washed off with water leaving a light-stable print.
A similar process was used to produce printing
Cingular Ringtones proofs for
poulaines of offset printing.
Blueprints have mostly been replaced by
staging the Diazo prints or
raids north whiteprint/whiteprints, which have blue lines on a white background; thus these drawings are called ''blue-lines''. These are sometimes also known, incorrectly, as blueprints.
camps can Revision control was done in contrasting color on the blue-lines, for example red markup of a blue-line copy by the engineer, then yellow markup on the copy by the draftsman who implemented the changes on the original drawing, then brown markup by the checker, on a check-print (a ''brown-line''). Finally, the architect or engineer, draftsman, checker and supervisor would sign the original drawing, thus making it a legal document.
