Optical Characteristic of Ink Jet Prints Conditioned by Substrate Ageing

The investigation results of optical characteristic and the relevant values essential for the quality of reproduction of the Ink Jet impressions in relation to the defined conditions of the accelerated ageing are presented in this paper. The results show that the ageing process influences the optical properties of the printing substrate in the following sequence ; recycled paper, fine art paper and offset paper. By analysis of FT-IR spectrum smaller increase intensity of the carboxyl peak can be noticed and the changes in the area, for which C=O vibrations are responsible, which is the result of the oxidation changes on aged paper in relation to the non aged paper. With prints on aged paper the greatest aberration in yellow and cyan happens on the fine art paper. Quick closing of screen in the printing is preformed on the aged paper in relation to other samples series can be noticed.
