Keywords:Geo, Fireldwork (interpretive act), Foraging, Prototyping , Creativity, Learning through expressive activities

About Us
Based in Oe-town in central Yamagata Pref., YOSHIKATSU is engaged in four basic activities: Procuring materials, Figuring out how to make things, Prototyping, and Implementation and manufacturing with "Foraging, Design, and Super-special printing" as its main areas of activity.
YOSHIKATSU's creations, which incorporate fieldwork and prototyping methods, range from printed materials to artwork, furniture design, web design, branding and concept-making, and workshop program development.
In this session, the members of YOSHIKATSU will present some case studies of engagement programs, art programs, and other activities conducted by Foraged Colors, a development and research project to create ink from foraged materials.

What is "Foraged Colors"?
From Selecting Colors to Making Colors. Foraged Colors aims to produce colors from materials gathered from the sea and mountains, implementing these colors in contemporary society. * Patent: Bio-based pigments (No. 7542886)


History
2021:
Development of pigments that use plant dye and water-based binder for fabrics.
Development of an oil-based binder for printing.
2022:
Establishment of pigment manufacturing flow.
2023:
Establishment of manufacturing flow for water-based and oil-based binders.
Test for mass production, Research, and development of proprietary mediums, and implement education programs with public participation. Holding exhibitions.
2024:
Find basic colors for industrial printing (CMYK = four components of color: cyan, magenta, yellow, and black) and make prototypes of pigmented products. In collaboration with printing companies, experiments are being conducted on letterpress printing and offset printing, which require high-precision ink, to launch them as printing services.
