When these components are examined, it is seen that they contain petrochemical substances. During and after the printing process, some of these components are separated from the ink as waste material and are mixed with air, water or soil, thus damaging nature and human beings. Considering this problem, safflower oil and natural (Pinus pinaster) resin were used in this study to produce bio based offset printing ink varnish, one of the main components of the ink. Safflower oil and (Pinus pinaster) resin were mixed in different proportions to form varnish with suitable viscosity to the printing ink composition. The usability of these varnishes as an alternative for varnishes produced with mineral oil in standard offset printing ink was investigated. Magenta color standard offset printing ink was prepared with these varnishes and sample prints were printed on coated paper, uncoated paper, Bristol board with IGT C1 offset printability tester. Test prints were examined in terms of specialties such as drying, L*a*b and density with a spectrophotometer. As a result of the measurements and determinations, it was determined that the varnish produced with safflower oil and (Pinus pinaster) resin can be used instead of offset printing ink varnishes produced with mineral oil.eninfo:eu-repo/semantics/openAccessBahçe BitkileriPolimer BilimiGıda Bilimi ve TeknolojisiBitki BilimleriMühendislikKimyaArticle626267432219
