The standardization of printed prints is an important factor in graphic production because the quality of the printed print largely depends on it. With the help of analysis and measuring instruments, we can come to the conclusion that the changes are more threatening to the printing process. In the given work, the tests were performed on GALERIE ART GLOSS weights of 150 g / m² and VANTAGE GLOSS weights of 250 g / m². Three different jobs were printed on the paper of this grammar, with a similar circulation and a different time period of printing.
By comparing the results of measuring optical density, color overlap, gray balance, CIE L * a * b *, spectral reflection and whiteness and yellowness of the paper, it is possible to see how the quality during printing on the graphics system KBA Rapida 160/8 deviates from the original values.
