The diploma thesis deals with the study of the process of grinding aggregates of particles of a mixture of powdered lanthanide oxides in the dowanol solvent. The formed dispersions were characterised and used for the preparation of printing inks and subsequently for the printing of labels with chemical codes readable by XRF spectrometry. The aim was to study the milling process, to verify the reliability of reading and recognition of marks with the appropriate codes and to monitor the influence of the additive of the up-conversion powder on the resulting relative intensities of the elements in the chemical code. The statistical significance of the differences in the averages of relative intensities was assessed based on the Student's t test.
