Abstract
método para correção de cores em uma impressora digital. a presente invenção refere-se a um método para a correção de cores de uma impressora digital em uma largura de impressão da impressora digital, tendo as etapas de: a) prover uma imagem digital especificada, a dita imagem digital tendo pelo menos um padrão de canal de cores, em que cada padrão de canal de cores é atribuído a um canal de cores de impressão da impressora digital; b) determinar pelo menos uma cor de teste da imagem digital especificada; c) gerar um padrão de teste digital, o dito padrão de teste digital sendo provido com pelo menos uma listra de teste de cor única que é destinada a ser impressa na largura de impressão da impressora digital, d) imprimir o padrão de teste digital através do uso da impressora digital; e) detectar os valores de cor do padrão de teste impresso com base em sua posição na direção da largura de impressão através do uso de um dispositivo óptico de medição de cor; f) gerar dados de correção para a impressora digital usando os valores de cores detectados e g) usar os dados de correção na impressora digital e/ou na imagem digital especificada. o método é adequado em particular à correção de cores de impressões subs-tancialmente de cor única e para reduzir a formação de listras na direção da impressão.
