Description from the seller
André Barbe, known as Barbe
(1936-2014)
Humor, erotic art and comic book illustrator
Member of the Humorists Association
Worked for Le Rire, Pilote, Hara Kiri, Charlie Hebdo
Illustrator of numerous works including the Cantique des Cantiques (La Musardine, Ed.), Don Juan, Mozart, Da Ponte, the full text of the opera (La Découverte, Ed.), Glénat, Albin-Michel, etc.
This rhodoid is a unique piece from my personal collection. It consists of 6 rhodoid strips taped onto a sheet of the same material for definitive insolation (see below for the technical aspect). Suggestion: before framing, you can detach these strips and tape them onto a glass pane and place everything on a colored background for a beautiful decorative effect (see photo example). Note that the two pink stains on one rhodoid are only light reflections; the document has no defect.
The rhodoid will be carefully packaged.
In offset printing, rhodoid (or transparent acetate/polyester film) historically refers to the transparent sheet used as an intermediate support for image transfer before the final engraving of the printing plates.
In the jargon of prepress printers of the traditional era (before digital), people often spoke of the "film" or the "rhodoid".
Here are its two major historical and technical functions:
1. Mounting and insolation of plates (Traditional Era)
Before today’s digital technologies, creating an offset printing plate involved a manual assembly step:
* The negative or positive film: Texts and images were first exposed on transparent films (often unfairly called rhodoids).
* The assembly: The prepress operator would assemble and tape these transparent films onto a stable transparent support (astralon) to compose the final page.
* The insolation: This transparent assembly was pressed against the offset plate (light-sensitive) in an insolation frame. Ultraviolet light passed through the transparent areas of the "rhodoid" to fix the image onto the metal plate.
2. Color control and registration (The "Blue" or Cromalin)
Since offset printing relies on the superposition of several colors (the four-color process: Cyan, Magenta, Yellow, Black), the rhodoid played a crucial verification role:
* Each color had its own transparent film.
* By superimposing the different rhodoids on each other by transparency, the printer could check the registration (whether elements were properly aligned) and get a preview of the final result before starting the presses.
What has changed today: CTP (Computer to Plate)
Today, the use of rhodoid in offset printing has almost entirely disappeared in favor of CTP technology (Computer to Plate).
