The Effect of Heat-Cured Clear Acrylic Coating on the Color of Artificial Iris

The effect of heat-cured acrylic resin coating on the color of artificial irises fabricated using oil painting, laser printing, and inkjet printing was investigated. Sixty artificial irises (30 brown, 30 blue) were created on paper and measured using the CIELAB color system before and after coating. Color changes were evaluated using the CIEDE2000 formula. Results revealed significant color changes in all groups, influenced by fabrication technique and color. For brown irises, laser printing exhibited the lowest color change, followed by oil painting and inkjet printing. For blue irises, inkjet printing displayed the lowest color change, while oil painting and laser printing showed no significant difference. Overall, heat-cured acrylic resin coating affects iris color, with laser printing being preferred for brown irises and all techniques suitable for blue irises.
