Abstract

"COMPENSAçãO DE NãO LINEARIDADE DA LINHA DE EXPLORAçãO EM UM SISTEMA ROS". Arquitetura de sistema para correção de não linearidade explorada em uma impressora usa qualquer explorador de saída por rastreio tendo perfil de não linearidade explorada previamente armazenado na memória de uma estação de testes instalada com qualquer placa de pixels. A placa de pixels inclui o registro de tabela de correção em que a placa de pixels utiliza o perfil de não linearidade explorada do explorador de saída por rastreio a fim de calcular o registro de tabela de correção para corrigir o registro errado de pixels.
