Abstract
(EN)
The invention relates to a chromatic reintegration method for works of art based on the use of color tables or charts as color reference system. The invention defines the use of color tables or charts (Figure 1) as a color reference system on the basis of which the colors to be restored in a work of art (Figure 7) can be identified in such a way that their trichromatic components yellow, magenta and cyan or their four chromatic components yellow, magenta, cyan and black and their corresponding proportions can be specified. This makes it possible to effect restoration using traditional restoration systems and to initially know in an orientational manner, both in terms of quality and quantity, the colors to be used to achieve the desired result. The invention describes the structure of said color tables or charts. Alternative methods for obtaining said color tables or charts, e.g. serigraphy, lithography, printers, plotters, etc., are also described in the invention.
(ES)
La presente invención define la utilización de tablas o cartas cromáticas como un sistema de referencia cromático (figura 1) a partir del cual se pueden identificar los colores a reintegrar en una obra (figura 7), de forma que éstos puedan ser especificados a partir de sus componentes tricromáticos: amarillo, magenata y cian, o bien, cuatricromáticos: amarillo, magenta, cian y negro, y en su correspondientes proporciones. De esta forma, es posible realizar la reintegración por los sistemas de reintegración tradicionales conociendo inicialmente de manera orientativa, tanto cualitativa como cuantitativamente, los colores que se han de utilizar par obtener el resultado deseado. Se describe la estructura de estas tablas o cartas cromáticas, y por otra parte se citan diferentes métodos alternativos de obtención de las mismas: serigrafía, litografía, impresoras, plotters, etc.

L'invention concerne un procédé de réintégration chromatique d'oeuvres d'art faisant appel à des tables ou cartes des couleurs comme système chromatique de référence. Cette invention définit l'utilisation de tables ou de cartes des couleurs (fig. 1) comme système chromatique de référence à partir duquel on peut identifier les couleurs à réintégrer dans une oeuvre (fig. 7) de manière que celles-ci puissent être spécifiées à partir de leurs composants trichromatiques: jaune, magenta et cyan ou quadrichromatiques: jaune, magenta, cyan et noir dans les proportions adéquates. Ainsi, la réintégration est assurée par les systèmes de réintégration traditionnels connaissant, tant sur le plan qualitatif que sur le plan quantitatif, les couleurs qu'il faut utiliser pour obtenir le résultat souhaité. L'invention concerne aussi la structure de ces tables ou cartes des couleurs et différents procédés d'obtention de celles-ci ainsi que les instruments connexes, à savoir la sérigraphie, la lithographie, les imprimantes, et les traceurs entre autres.
