- Pulp obtained by processing straw of three types of grains (wheat, barley, triticale)
- Formed 10 types of printing substrates with a different straw pulp content and a control substrate without straw pulp
- Gained monotone prints on laboratory produced printing substrates with different printing techniques (offset, gravure, flexography, screen and digital printing)
– printing of solid tonality of conventional and contemporary inks that are dried when exposed to UV (UV inks) in four colours (cyan, magenta, yellow and black) with 5 printing techniques on 10 different printing substrates with a total of 360 different monotone prints whose tone reproduction quality will be the subject of this research.
- Gained multi-tone prints on laboratory produced printing substrates made by applying different printing techniques (offset, gravure, flexography, screen and digital printing)
– printing with cyan and yellow, magenta and yellow, cyan and magenta, and cyan, yellow and magenta inks of solid tonality with conventional and contemporary inks that are dried when exposed to ultraviolet radiation (UV inks) by applying 5 printing techniques on 10 different paper substrates will result in a total of 360 different multi-tone prints whose tone reproduction quality will be the subject of this research.
- Recommendation for making prints on paper made with straw pulp (define printing technique and appropriate ink) with satisfactory quality of reproduction
– results of the quality of prints obtained by analysing the penetration and migration of the ink into the printing substrate
– results of prints based on certain qualitative parameters: penetration and migration of the ink on laboratory substrates, graininess and inequality of full-tone reproduction, the quality of tone reproduction for cyan, magenta, yellow and black (L* a* b* values) compared to ISO standards and Pantone standardized colour catalogue, trapping and the total amount of ink available on the substrate
- Guidelines for the durability of prints on substrates with a different percentage of straw pulp in the packaging or in publications
– print durability results are based on the stability of prints in relation to chemical agents, pressure, temperature, humidity and UV radiation
