Abstract:Namen naloge je bil z laboratorijskimi testi ugotoviti kompatibilnost izboljšanega pufra (P – 55 Eko pufer), ki bo kompatibilen z novimi optiline barvami Cinkarne Celje. Pufer (v tiskarstvu) je koncentrat, ki se dodaja v majhnih količinah (do 5%) v vlažilno tekočino, ki v ofsetnem tisku vlaži čiste površine in s tem onemogoča prenos barve na proste (netiskane) površine. Kompatibilnost barva – pufer se nedvoumno najbolj ugotavlja pri samem tisku. Vendar je bilo predhodno potrebno narediti primerjalne laboratorijske teste med različnimi pufri, ki so nam dali določene rezultate. Vlažilnim raztopinam smo izmerili pH vrednosti, elektroprevodnosti, površinske napetosti, gostote, kislinske komponente, sušino in določili vodno ravnotežje z rdečo in rumeno optiline barvo Cinkarne Celje.

Title:THE COMPARISON OF DIFFERENT FOUNTAIN SOLUTIONS FOR OFFSET PRINTING
Abstract:The purpose of this diploma work was a laboratory test for the buffer improvement that would be compatible with the new colours from Cinkarna Celje which they started producing this year. Buffer (in printing) is a concentrate that is added in small quantities (up to 5%) to the hydrating fluid which moisturizes clean surfaces in the offset printing and thus prevents the transfer of colours on the free (unprinted) surfaces. Compatibility of colour - buffer is most notably determined in the press itself. However, it was previously necessary to do comparative laboratory tests of various buffers, which gave us some results. pH, conductivity, surface tension, density, acid components and the amount of dry matter were measured in the hydrating solutions. The water balance of red and yellow optiline colors from Cinkarna Celje were determined.
Keywords:offset printing, printing inks, surface tension
