* Assemblage: Johns often incorporates everyday objects into his paintings, such as targets, flags, and numbers. This technique, called assemblage, blurs the line between painting and sculpture.
* Encaustic: Johns frequently uses encaustic, a technique that involves painting with pigments mixed with beeswax. This method gives his works a unique texture and luminous quality.
* Collage: Johns frequently uses collage, incorporating different materials like newspaper clippings, fabric, and maps into his canvases. This technique adds depth and layers of meaning to his work.
* Screenprinting: Johns also uses screenprinting, which allows him to create bold, graphic images.
These techniques, along with his use of everyday imagery and iconic motifs, contribute to Johns' unique and influential style.
It's important to note that Johns doesn't have a single "signature technique." He creatively utilizes a variety of methods, blending them to create complex and multi-layered artwork.
