G1 = Tropicalgin; G2 = Chromaprint premium; G3 = Hydrogum 5; SG1 = No disinfection; SG2 = Spray disinfection; SG3 = Immersion disinfection; C1 = No storage; (C2) 72 h of storage and (C3) 120 h of storage
Higher scores in different test categories indicate higher accuracy of the reproduced details
Kruskal–Wallis test, P = 6.25E−16
Within each column, same superscript letters indicate no difference between test categories within the same test group (Mann–Whitney, P > 0.05)
Within each row, same superscript numbers indicate no difference between test groups within the same test category (Mann–Whitney, P > 0.05)
