Usability and printability of paper substrates with non-wood fibres for graphic products printed by five printing process

Customers are usually unaware of the process required to reproduce graphic products that are used on a daily basis. Manufacturers of graphic products and merchandise are aware that, regardless of the substrate they are printed, they must ensure consistent colour matching and print quality to attract attention on store shelves and ensure customer loyalty. Packaging, labels and publications are mostly printed using multicolour printing, whereby different colour shades are reproduced with the three standard process colours (cyan, magenta and yellow) in different ratios. The quality of the graphic product depends largely on the origin of the raw materials used for the printing substrate, the type of ink and the technology used for printing. The paper substrate most used for printing labels, packaging, or publications is generally made from cellulose fibres derived from wood, non-wood or non-plant sources. Nowadays, the use of non-wood lignocellulosic fibres resources plays an important role in optimizing raw materials for paper production. The aim of this research was to evaluate the usability and printability of paper substrates with the addition of non-wood fibres for graphic products printed by digital, flexographic, gravure, screen and offset printing process.
