The best of these papers, with suitable pigment-based ink systems, can match or exceed the image quality and longevity of photographic gelatin-based silver halide continuous tone printing methods used for color photographs, such as Fuji CrystalArchive (for color prints from negatives) and Cibachrome/Ilfochrome (for color prints from positive transparencies). For printing monochrome photographs, some photographers believe that traditional silver-based papers exhibit deeper black tones and smoother tonal gradation compared with inkjet prints; however, objective testing of contemporary fine art inkjet media (in particular the finer gloss and luster papers) does not support these impressions. Paper is one amongst several key elements determining the quality of the print; the others are the ink, the printer, the printer/paper profile, the software used for print preparation and most importantly - the skill and expertise of the print-maker.
