The people behind the work.
Robert Aalbers and Sem Kuis, also known as Sempre Tattooer. Two artists with a shared commitment to design and craftsmanship.
Robert and Sem work together at Clean Solid across a broad range of tattoo styles. Their shared starting point is thoughtful design, good craftsmanship and tattoos made with the long term in mind.
Robert Aalbers
Founder of Clean Solid Tattoos, tattoo artist, visual artist and designer. Robert's background is rooted in skateboarding, punkrock and traditional old-school tattooing. His graphic approach also runs through prints, murals and design projects.
Robert began his tattoo career at No Hope No Fear in Amsterdam with Adam Kotger. He developed his traditional old-school experience in the United States among other places, and participated in international tattoo conventions. In 2000 he founded Clean Solid Tattoos in Waalwijk.
Robert finds inspiration everywhere: a shell, a leaf, a shadow or an interesting arrangement of shapes. An idea may become a tattoo, art print, mural or spatial project. His graphic approach connects the work.
Sem Kuis / Sempre Tattooer
Sem Kuis works as a tattoo artist at Clean Solid under the name Sempre Tattooer. Alongside his studio work, he creates murals with Robert, including projects at Hall of Fame in Tilburg and Kandinsky in Waalwijk.
