Graphic substrates and surfaces have different requirements, which are addressed using specific types of large-format digital printing inks. Each ink is designed to adapt better to a particular surface, so understanding the differences between them is important to achieve the best print quality. <\/p>\n
These inks are mainly used in inkjet printing processes. This technology works by spraying ink onto the surface through a jet mechanism. Below, we explain the main types of inks used in large-format digital printing.<\/strong><\/p>\n <\/p>\n Most of their composition is water mixed with dyes or pigments<\/strong> that provide colour, giving them a wide tonal range. They are mainly used for printing on paper and cardboard substrates, as their adhesion on other materials is limited. They are not recommended for outdoor applications<\/strong>. They are mainly used for: <\/p>\n One of the main characteristics of these water-based inks is that they are non-toxic <\/strong>and odourless <\/strong>during printing and use. However, although they can produce vibrant colours, <\/strong>these may fade more quickly. Pigment-based versions offer better durability but still have limited resistance to water,<\/strong> weather conditions and UV light. <\/p>\n These inks use a solvent-based composition that carries colour pigments. The result is highly durable and resistant<\/strong> prints. They are mainly used for outdoor elements because their adhesion to materials such as plastics is very strong. Their main applications include: <\/p>\n In solvent printing, the solvent evaporates during the printing process, leaving the pigment fixed on the substrate. For this reason, solvent inks are not considered environmentally friendly, which has led to the development of more sustainable alternatives. <\/p>\n Eco-solvent inks were developed as a more environmentally responsible alternative<\/strong> to solvent inks, which have higher toxicity and stronger odours. <\/strong>These inks contain fewer volatile organic compounds (VOCs), making them less harmful to both health and the environment. Their main applications include: <\/p>\n They generally offer lower durability and slightly less colour intensity compared with solvent inks, but they are a strong alternative<\/strong> due to their lower environmental impact. They can also be used indoors because they do not require extensive ventilation. <\/p>\n Latex inks contain no contaminating volatile organic compounds (VOCs). Among all ink technologies, they offer one of the highest levels of sustainability.<\/strong> <\/p>\n Also known as resin inks,<\/strong> they are composed of a combination of water, heat-curing resins and additives that help create the printed image. They are similar to solvent inks but have the advantage of being non-toxic and odourless.Water-based inks<\/h2>\n
