Record 1 2019-07-19

English

Subject field(s)
  • Reprography
  • Electrostatics
DEF

A process for copying graphic matter by the action of light on an electrically charged photoconductive insulating surface in which the latent image is developed with a resinous powder(such as toner).

CONT

Xerography.... a process that first places an electrostatic charge on a plate [or drum]. An image is then projected onto the plate [or drum], causing the charge to dissipate in the illuminated areas, thus allowing an applied coating of resinous powder to adhere only to the uncharged(dark) areas. The powder is then transferred to paper and is fixed by heat.

OBS

This process is used in photocopiers and laser printers.

French

Domaine(s)
  • Reprographie

DEF

Procédé d'impression électrostatique permettant de reproduire à sec des documents sur n'importe quelle surface en utilisant des poudres spécialement préparées qui remplacent l'encre.

OBS

Ce procédé est utilisé dans les photocopieurs et les imprimantes laser.

Record 2 2017-04-19

English

Subject field(s)
  • Reprography
  • Photography
CONT

Electrostatic copying.... the charged image is formed on the surface of a metal drum coated with selenium. The image is made visible by the application of a plastic powder, called toner, that has been given the opposite electrical charge and is thus attracted to the charged image on the drum. The toner image is then transferred to plain, uncoated paper by the attraction of another opposite charge placed behind the paper. The toner is fused onto the paper by heat to produce a permanent image.

French

Domaine(s)
  • Reprographie
  • Photographie
CONT

Procédés électrostatiques. La projection optique de l'image se fait sur un cylindre de sélénium [...] Dans sa rotation, le cylindre (ou tambour) subit les divers traitements ci-après [...] : - Charge électrostatique dans l'obscurité par effet Coronna. - Projection optique d'une bande étroite de l'image de l'original, créant une image latente sur le cylindre. - Dépôt et répartition d'une poudre colorante sur l'image latente. - Transfert de l'image révélée sur un papier copie qu'on chargera d'électricité de signe contraire pour y attirer la poudre fixée sur le cylindre.

Record 3 2012-01-31

English

Subject field(s)
  • Radiography (Medicine)
OBS

xeroradiography : A method of roentgenography using, instead of film, a metal plate coated with a semiconductor, such as selenium. The image is obtained by dusting the plate with a dark powder, the particles of the powder being fixed in place by the electrical charges resulting from exposure of the plate to X rays.

French

Domaine(s)
  • Radiographie (Médecine)
OBS

Impression sans contact, n'utilisant pas de substances chimiques liquides.

Record 4 2008-03-05

English

Subject field(s)
  • Non-impact Printing
DEF

A printing process using static electricity to deposit dry powder ink or, less frequently, liquid ink, on a sensitized surface in order to create an image.

French

Domaine(s)
  • Impression sans impact
DEF

Procédé de reproduction sans contact ni pression fondé sur certaines propriétés de l'électricité statique (photoconductivité de certains corps) [dans lequel] l'encre, sec ou liquide, est transportée de la forme au papier par attraction et est fixée par cuisson.

Record 5 2004-08-30

English

Subject field(s)
  • Electrostatics
  • Graphic Arts and Printing
  • Photoengraving
DEF

Reproduction process involving the application of a positive electrostatic charge into the image of a document and subsequent treatment with negatively charged powder which adheres to the positive image area.

OBS

[This] process utilizes the fact that in certain substances an electrostatic charge will be dissipated by light where it strikes, but will remain in unlit areas.

French

Domaine(s)
  • Électrostatique
  • Imprimerie et arts graphiques
  • Photogravure
DEF

[...] un procédé de REPROGRAPHIE qui utilise les propriétés photoconductrices de certaines substances, c'est-à-dire la propriété qu'ont certaines substances d'être plus ou moins conductrices de l'électricité en fonction de l'éclairement auquel elles sont soumises.

OBS

reprographie : ensemble des techniques qui permettent d'assurer la reproduction de documents [...]

Spanish

Campo(s) temático(s)
  • Electrostática
  • Artes gráficas e imprenta
  • Fotograbado
DEF

En una máquina copiadora de documentos es un proceso en el que la copia resulta, directa o indirectamente, del efecto de la luz sobre un material eléctricamente cargado.

Record 6 1996-10-11

English

Subject field(s)
  • Inks and Colour Reproduction (Graphic Arts)
  • Electronic Publishing
  • Simulation (Cybernetic Systems)
DEF

A toner, either dry powder or liquid, used to develop electrostatic images, as in a photocopying machine. The charge of the pigmented particles is opposite to that of the image; the particles are thus attracted to and adhere to the image-bearing surface.

OBS

Electrostatic inks are not inks in the truest sense, nor should they be confused with the organic pigment in ordinary ink.

French

Domaine(s)
  • Encres et couleurs (Industrie graphique)
  • Éditique
  • Simulation (Systèmes cybernétiques)
DEF

Toner, liquide ou sec, utilisé dans les procédés électrostatiques pour révéler l'image latente.

OBS

Les toners électrostatiques, liquides ou secs, constituent les matières colorantes de l'encre employée en électrophotographie; se distinguent des toners magnétiques (employées en magnétographie).

OBS

the print is first developed with powder, after which a lifter with a sticky surface is pressed against the print and then pulled away. Part of the powder sticks to the surface of the lifter and gives a mirror image of the original print.
