“…Pulping conditions are presented in Table 1. 9 Laboratory papers of approximately 42.5 g/m 2 (20 cm diameter) were formed in a Rapid-Köthen sheet former (FRANK-PTI) according to EN ISO 5269-2:2004 nine standards from a mixture of triticale pulp (in proportions of 10%, 20% or 30%) and pulp from recycled wood fibres (Figure 1). Figure 1 presents the process flow of laboratory paper production.…”

“…7,8 The current usage of non-wood fibre sources in papermaking include straw, sugar cane bagasse, bamboo, kenaf, hemp, sisal, abaca, cotton linter and reeds, as well as some exotic raw materials like aquatic plants, tea waste, palm leaf and banana stem. 9 In this research, laboratory printing papers were produced on a laboratory sheet former using a mixture of triticale pulp in different weight ratios (10%, 20% and 30%) and pulp of recycled fibres. Adding triticale pulp to recycled fibres pulp to create an innovative paper is of great importance considering that straw is currently burned or rots on the ground.…”

The packaging and labels graphic industry is dominated by several main printing techniques, namely flexography, offset, gravure and digital printing. Each technique is suitable for a particular type of graphic product and differs in the way ink is transferred to the printing substrate and by the type of image carrier employed. Depending upon the printing process, the printing ink is transferred to the substrate either directly or indirectly. High-quality prints in analogue technologies are based on ink transfer from printing plate to printing substrate, while digital printing is based on inkjet or statical ink transfer directly to the printing substrate. Since the development of digital commercial printing in the mid-1990s, devices have emerged that can reproduce almost the same quality in any required application. Digital printing has created a revolution in the printing industry, where inkjet printing and electrophotography printing are fast-growing digital printing techniques. Inkjet printing is one of the most popular non-impact printing technologies, where printing is performed without

“…The quality of prints on papers with pulp from agricultural residues has not been thoroughly investigated. In recent research [9], the possibility of using mixed pulp from wood and triticale straw up to 30% was shown on a laboratory scale. The use of paper with pulp from agricultural residues (wheat, barley and triticale straw) in the printing industry has been confirmed in several studies [10][11][12][13].…”

Nowadays, there is a strong initiative to use recycled or biodegradable materials in all aspects of production including the graphic industry. In this study, paper was used as a material fulfilling the two of mentioned properties. Under laboratory conditions, papers were made of 70% pulp from recycled wood fibres with an addition of 30% straw pulp (wheat, barley or triticale). Considering the importance of the possibility of printing such media based on their end use, the influence of fibre type on vapour barrier properties was studied and overall migration to hydrophilic and fatty food simulants was measured. Analyses were performed on digital, flexographic, and offset prints obtained by printing laboratory papers with UV-curable black ink. It was found that prints produced using the offset technique, in which the ink remains on the surface of the paper, had lower overall levels of migration compared to other printing techniques. The paper produced appears to have the potential to be used as a secondary food packaging material.

“…Since paper substrates have been traditionally produced from wood-derived cellulose fibres, the consumption of raw wood materials increased significantly but also led to a global awareness of the possibility of forest exploitation and the importance of reusing post-consumer wastepaper as a source of cellulose fibre [1,2].…”

The use of recovered paper in the paper and board industry worldwide has increased in the last decade. The recycling process affects several properties of the paper, so recovered pulp needs to be enriched with a certain amount of virgin fibre to increase the strength and quality of the paper, and thus the quality of the print. Since the cellulose-based printing substrates are sensitive to photolytic damage caused by exposure to light and high temperature, the focus of the research was to evaluate the stability of digital UV inkjet prints on laboratory substrates with wheat pulp. Assessment of the optical stability of laboratory substrates and prints made on them after ageing treatment was based on the reflectance spectra measurements before and after artificial ageing. In order to observe the optical changes that occur in cellulose printing substrates, unprinted and digital printed substrates were placed in an artificial ageing equipment SunTEST XLS+ test chamber according to standard ASTM D 6789-02. The test chamber emits visible and near ultraviolet electromagnetic radiation in the range from 290 nm to 800 nm. With the deterioration of the optical stability of unprinted and digital printed substrates, it was observed through the reflectance spectra (R) and the Euclidean colour difference (ΔE00*) that the highest colour degradation of all analyzed samples, occurs in the first 48 hours of artificial ageing. The results of this analysis confirm that the addition of wheat pulp in paper pulp provides better optical stability of unprinted and digital printed laboratory substrates.
