Özet: Metal Offset Printing System is one of the important printing systems produced in metal packaging production. The image to be printed in this system is first transferred to the offset printing plate. When the system starts up, the ink in the places to be printed on the plate and the dampening water in the places that will not be printed are first transferred to the blanket with a certain pressure and then to the metal substrate passing between the blanket and the printing cylinder with a certain pressure. In this study, test prints of 0.2g and 0.3g weights were made with Mineral Oil Based Conventional ink and UV ink used in metal offset printing and the effects of ink change and quantity change on printing results were investigated. For this purpose, test prints were carried out on the Unenamelled and Enamelled surfaces of the metal in the IGT Test Printing device with the same environment and material properties as Conventional and UV ink. The average of the measurements made over 3 of the 4 test prints made for the measurement were taken visually properly. Comparison was made by measuring the density of the prints, printing brightness (printing brightness) and Chroma. After the examination, it was observed that the enamel coating had sufficient contrast writing, ink density and Chroma values and an effective increase in print gloss value, as well as the type and quantity of ink, affect the print density and print gloss.
