Abstract

"PROCESSO E APARELHO DE REPRODUçãO FIEL EM CORES". Em qualquer suporte, de um documento original colorido (quadro, aquarela, etc.), compreendendo: (1) uma esquadrinhadora que abrange um dispositivo detector e analisador de cores, que decompõe cada superfície elementar ('pixel') do documento original, determinando as proporções em que ela se decompõe com referência a três cores previamente escolhidas, mais a proporção de branco (se o respectivo ponto cromático estiver na zona clara do hexaedro das cores) ou de preto (caso tal ponto se encontre na zona escura do mesmo hexaedro), um dispositivo para efetuar a varredura em linhas horizontais ou verticais do documento original e um mecanismo calculador para transformar essas proporções em coeficientes k~ j~, que são registrados seja de maneira contínua (registro gráfico analógico), seja discretamente por pontos seguidos (registro magnético digital); (2) um mecanismo de leitura desses coeficientes e sua transformação em comandos para dosagem das quatro cores; (3) um dispositivo impressor da mistura de cores resultante no suporte escolhido; e (4), accessoriamente, dispositivos pantográficos para reduzir ou ampliar a reprodução e para multiplicar seja a varredura, seja a reprodução."FAITHFUL COLOR REPRODUCTION PROCESS AND APPARATUS". On any support, of a color original document (frame, watercolor, etc.), comprising: (1) a scanner comprising a color detector and color analyzer, which decomposes each elementary surface ('pixel') of the original document, determining the proportions in which it decomposes with reference to three colors previously chosen, plus the proportion of white (if the respective color point is in the light zone of the color hexahedron) or black (if such point is in the dark area of the same hexahedron). ), a device for scanning horizontal or vertical lines of the original document and a calculating mechanism for transforming these proportions into coefficients k ~ j ~, which are recorded either continuously (analog graphic record) or discretely followed by dots ( digital magnetic record); (2) a mechanism for reading these coefficients and their transformation into commands for dosing the four colors; (3) a resulting color mix printing device on the chosen support; and (4), additionally, pantographic devices for reducing or enlarging reproduction and for multiplying both scanning and reproduction.
