The students of the first courses of Graphic Arts have had the opportunity to know a little more in depth the manufacture and characteristics of the special papers. We have received the visit of Daniel Domínguez, representative of Guarro Casas, a paper factory with more than 300 years of history. From his hand, we have been able to see the whole process of manufacturing the paper and the technical and physical characteristics of which it is provided to develop the design and printing products. A world, that of paper, full of possibilities, textures and colour.
