Abstract

"MáQUINA E PROCESSO DE IMPRESSãO ELETROSTATOGRáFICA". São revelados um processo e um aparelho para eliminação de revelação indesejável de potenciais de carga de plano de fundo em um sistema eletrostatográfico de múltiplas cores, em que a aplicação de uma polarização de revelador em uma determinada estação de revelação é seletivamente controlada para ser substancialmente idêntica ou superior à voltagem da imagem de plano de fundo da imagem gerada por uma estação de formação de imagem precedente de tal forma que o diferencial de voltagem entre as partículas de tonalizador na estação de revelação e áreas de plano de fundo incluindo as áreas de imagem anteriores é substancialmente igual a zero e as forças eletrostáticas atuantes sobre as partículas de tonalizador são insuficientes para atraírem as partículas de tonalizador para a imagem residual. São revelados um processo e um aparelho para eliminação da re-revelação de imagens precedentes em um sistema eletrostatográfico de múltiplas cores e, mais particularmente um sistema de múltiplas cores de imagem-sobre-imagem, em que as polarizações de formação de imagem e de revelação para cada cor no processo de impressão são sistematicamente ajustadas para eliminação de diferenciais de potenciais de carga que podem operar de forma a atraírem partículas de tonalizador para o elemento receptor em um procedimento subseq³ente de revelação de imagem.
