RELATO DE EXPERIÊNCIA: A IMPORTÂNCIA DA INSTRUMENTAÇÃO ÓPTICA NO APERFEIÇOMENTO DA FLEXOGRAFIA

Abstract

The present work is based on the experiences acquired during the curricular internship at a company that manufactures flexible plastic packaging in southwestern Goiás, with a focus on the printing sector. The activities developed are centered on the ink room, ranging from the approval of received ink batches to the release of specific colors for machine production. The quality control routine involves the use of high-precision optical instrumental chemical analyses. The device implemented in the process is a spectrophotodensitometer, which measures light reflectance and provides fundamental parameters to define the color and the quantitative difference between a standard and the sample, the delta E (ΔE), enabling the identification of tonal variations. In addition, specialized software, such as Apollo, is used to check for failures during the wide-web printing process. This work demonstrated that data collection and analysis allow for effective monitoring of the flexographic process, ensuring operational fluidity and the maintenance of required quality standards, thus developing an industrial routine of excellence.
