Abstract

"COMPENSAçãO DE ERRO DE RECARGA EM MéTODOS DE CONTROLE DE PROCESSO EM CORES". Processo de controle de toner, que inclui a determinação substancial de como o erro de recarga afetará uma imagem impressa, modulação da densidade de cor de um emplastro de teste para compensar o erro de recarga antes da impressão do emplastro de teste, impressão do emplastro de teste modulado, detecção da imagem digital, ajuste da saída de toner de acordo com a imagem digital detectada.
