The visual quality of the print result is largely dependent on the optimum level of coalescence process of the underprint material and the ink. The structural characteristics of the paper are extremely important in that the print can be obtained without loss and with the desired colour value. Since paper and cardboard are heterogeneous and interchangeable materials, it is necessary to measure the structural properties and determine their effect on the printability parameters of these properties. In this study, 90 g/m2 alternative papers, which are widely used in a certain product group and have different characteristics, are selected. 5 alternative papers were selected, elongation, strength, contact angle and surface energies were determined with the calibrated test devices. With offset printing, the ink is transferred to the paper by keeping the ink quantities constant with the cyan, magenta, yellow and black lines. Inks were measured for density and colour measurements followed by light fastness test and colour measurements were repeated. Differences in colour and paper properties are compared with multi-criteria decision making methods and given graphically. The optimal paper was selected using the TOPSIS (Technique for Order Preference by Similarity to Ideal Solutions) method, which is a multi-criteria decision-making method for choosing the most appropriate paper for production.
