PRINTING The
Moulin du Got never processed its paper on the spot, but now has the
opportunity to do so as it has received several machines dating from
different periods, some from the Foyer Rural de Saint Léonard.
Coupled with the discovery of 500 years of papermaking the printing
workshop offers you 500 years of evolution in the Graphic Arts. Since the beginning of time men have tried to communicate: from the cave man’s drawings to writing on all kinds of materials (stone, wood...) knowledge was written down, but not widely spread. We owe to the invention of paper, and then to the printing press invented by Gutenberg in 1437 the possibility of a universal transmission of that knowledge.
Cold
typographic composition :
Upper and lower case.
Assembly by hand of different graphic symbols, different shapes and
sizes with blanks and spaces as required by the text and the desired result.
Use of a composing-stick, typo meter, sundry brass accessories, stamps, and
small pincers called tweezers.... Hot
typo-setting :
Linotype. A Composing Machine.
Automatic assembly of brass type moulds, selected with a keyboard, to
form a whole line of text in a single block by projecting molten lead. Once
used these lines of text can be melted and the process renewed. The
Printing press
: Stanhope (1795); Platen press (1890); OFMI Heidelberg (1950)
The assembled elements making up a page are fitted into a metal frame to form a
solid block. This block is placed on the appropriate printing press and with
the application of black or coloured ink and a sheet of paper the printer
obtains a printed page. From the “Stanhope” to the semi-automatic
“Heidelberg “ production passes from 300 sheets per day to 300 sheets
per hour, and then to 3000 sheets per hour.
Lithography
: Lithographic Printing.
Invented in 1770 by SEMEFELDER this method of printing uses the
antagonism between oil and water, either using a special limestone or a
plate of grained zinc. A special crayon, or Indian ink, or lithographic ink
is used to draw the design thus blocking the grain of the stone or zinc.
Next the whole support must be dampened so that the grain of the
unblocked zone holds the water.
When the
stone or zinc is inked only the design, blocked, will hold the ink and when
the sheet of paper is pressed on to the support only the design is
reproduced. Embossing
:
Embossing Press
This art permits the deformation of paper so that an original subject
sculpted on wood or plaster appears in relief. A sheet of paper is pressed
between two moulds, one positive, the other negative, and keeps the shape.
Embossing gives effects of light and shadow.
Copper
plate engraving :
Press
This technique aims to reproduce on damp paper any design engraved on
plates of copper or zinc. Engraving these plates is the work of an artist.
The copper plate printer is only asked to
execute a reproduction.
