Artistic printmaking is an important field of visual expression that includes various printing techniques and enables in-depth exploration of visual elements. In this master's thesis, I will focus on examining the visual problem of tonal keys in artistic printmaking. The primary focus will be on the intaglio collagraph technique, through which I will explore a specific method of processing a visual motif by gradually introducing light from a dark base. My research will center on developing a personal approach to achieving gradual building of light from a dark foundation within the collagraph process. I am particularly interested in creating different brightness keys through the specific preparation of the matrix. The matrix is produced using a negative drawing method, which allows for gradual modulation of tonal transitions. Alongside this, I will analyse the expressive potential of this method and explore its applicability in the depiction of figurative motifs. Due to its technical accessibility and expressive versatility, collagraphy is a suitable technique for use in educational settings and is thus included among intaglio techniques in the national art curriculum for 8th-grade primary school. Through this research, I aim to contribute to a deeper understanding of the potential of collagraphy as an intaglio technique for exploring brightness keys and their effects in primary education. Additionally, I hope this thesis will contribute to the development of art didactics, as the results may be applied within the context of primary school art instruction, where intaglio printmaking is often overlooked due to technical and safety constraints.
