The defining shift begins with the Ootje Oxenaar series, where each denomination is constructed around a single dominant visual concept. The 10 gulden Kingfisher (IJsvogel) is built on sharp blue tonal control and avian form without traditional framing. The 50 gulden Sunflower expands into a saturated yellow field, turning botanical structure into a full-surface composition. The 250 gulden Lighthouse rises through vertical bands and concentrated blue-violet gradients, forming one of the most recognizable European banknote designs. Across these notes, Oxenaar embedded micro-level details — fingerprints, hidden motifs, and personal references — integrated directly into the engraving, creating a secondary layer of discovery for collectors.

The later transformation under Jaap Drupsteen removes even residual figurative balance. Denominations such as the 10, 25, 100, and especially the 1000 gulden Kievit shift into computer-generated grids, point-based raster structures, and sharply segmented color fields. The 1000 gulden stands as a fully abstract composition, integrating barcode elements for accessibility and embedding security features directly into the geometric system. These notes operate as engineered visual structures rather than traditional engraved documents.
