Resumo: | Brazil plays an important role in the consumption and production of ceramic tiles nowadays. The decoration of tiles by digital inkjet printing, due to its technical and aesthetic advantages, is a spreading technology and has already been adopted in the national industry. Ink sets acquired from different manufacturers differ in their extension behavior on the ceramic surface, in the definition of the printed pattern, in the range of printable colors, and in the ink yield, square meters of a same decoration that can be printed for unit volume of ink. Due to the peculiarities of this technology, there is still no methodology for evaluating the performance of the inks and there is very little published on this topic. This paper proposes a methodology for a comparative evaluation of the performance of industrial inks, aiming to help in the selection of these inputs by ceramic tiles producers. Drops of the evaluated inks were applied on a defined ceramic substrate. The colorimetric behavior and the extension of the ink were assessed as indicative parameters of the image quality and yield of the inks. The colorimetric characteristics and the size of the points produced with inks from different suppliers were significantly different for all the four colors of the inks evaluated. For all these colors, the results point to similar conclusions, demonstrating the validity of the method. Some technical characteristics of the inks were studied to identify the reasons for the different behaviors observed. The color differences between inks of different suppliers are explained by the different pigment phases in each composition of ink. The extension of the inks were greatly influenced by its viscosities. The more viscous inks, due to greater difficulty in penetrating the ceramic substrate, expanded more over it. |

A decoração de revestimentos por impressão digital por jato de tinta, devido às vantagens técnicas e estéticas que apresenta, já foi adotada na indústria do país e se difunde cada vez mais. Conjuntos de tintas adquiridos de fabricantes distintos apresentam diferenças em seu comportamento de extensão na superfície da peça, na definição do desenho impresso, na paleta de cores fornecida e no seu rendimento (metros quadrados de uma mesma decoração impressos por unidade de volume da tinta). Devido às peculiaridades dessa tecnologia, ainda não há uma metodologia para a avaliação do desempenho das tintas e muito pouco foi publicado a respeito do tema. O presente trabalho propõe uma metodologia para avaliar comparativamente o desempenho de tintas industriais, visando auxiliar na seleção desses insumos pelos produtores de revestimentos. Gotas das tintas avaliadas foram aplicadas em um substrato fixo e o comportamento colorimétrico e o índice de extensão dos pontos resultantes foram avaliados como parâmetros indicativos da qualidade da imagem e do rendimento das tintas. As diferenças colorimétricas e o tamanho dos pontos para tintas de fornecedores distintos foram bastante significativas, e os resultados apontam para conclusões equivalentes para todas as cores avaliadas, o que demonstra a validade do método. Algumas características técnicas das tintas foram estudadas para identificação das razões para as diferenças de comportamento observadas. As diferenças de cor entre tintas de fornecedores diferentes são explicadas pelas diferentes fases pigmentantes em cada uma delas. Os índices de extensão foram bastante influenciados pelas viscosidades das tintas. As tintas mais viscosas, devido a maior dificuldade de penetração no substrato cerâmico, se estenderam mais sobre o mesmo.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)porUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMUFSCarDecoração digitalDecoração por jato de tintaRevestimentos cerâmicosENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICAMetodologia para avaliação do desempenho de tintas para decoração digital de revestimentos cerâmicosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisOnline600600def1d9c8-353a-4dec-a3b5-c49b68749aedinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALDissAVL.pdfDissAVL.pdfapplication/pdf1821668https://repositorio.ufscar.br/bitstream/ufscar/7886/1/DissAVL.pdf42db42e0bbdf294d1344ec7943e5d40dMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81957https://repositorio.ufscar.br/bitstream/ufscar/7886/2/license.txtae0398b6f8b235e40ad82cba6c50031dMD52TEXTDissAVL.pdf.txtDissAVL.pdf.txtExtracted texttext/plain173099https://repositorio.ufscar.br/bitstream/ufscar/7886/3/DissAVL.pdf.txt6b5c0bc275d25ce8e498b153cc42a923MD53THUMBNAILDissAVL.pdf.jpgDissAVL.pdf.jpgIM Thumbnailimage/jpeg6172https://repositorio.ufscar.br/bitstream/ufscar/7886/4/DissAVL.pdf.jpga717d0c695bd06f79d1dd9ca35a45b2aMD54ufscar/78862023-09-18 18:30:58.502oai:repositorio.ufscar.br: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Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:30:58Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
