Investigating printing systems

In the Graphic Production subject, led by Lluc Massaguer, students carry out an experimental investigation on different aspects related to the graphic production process.

This edition has delved into existing printing systems which are no longer used, or those that have characteristics that make them peculiar.

Cèlia Mateu has experimented with Green Engraving with Tetra Pak and coffee ink.

The Green Engraving is a technique to make embossing matrices that uses the Tetra Pak as a printing form, which comes from the reuse of a food material, in a way that new waste is not generated but redefines its use.

This project uses an ink based on coffee grounds and water, without any chemical component that could be toxic, being able to clean the matrix with soap and water, without the need for solvent, completing an easy and simple process, as well as respectful with the environment. Thus, an element (coffee) is reused which, like the Tetra Pak, already had its use previously.

Sarah Barbuto has developed a hectograph, a printing apparatus that worked with gelatin. Being hydrophilic, it retained water-based inks.

She reproduced text in a short print run and combined the technique with Gel press, which has allowed her to arrive at more illustrative results.
