Print Permanence Ratings for Epson 9800 Printer and UltraChrome K3 Inks

Source: Wilhelm Imaging Research

Wilhelm Imaging Research has posted preliminary testing results for the new Epson Stylus Pro 9800 printer using the new UltraChrome K3 inks. The results are available either in online presentation or downloadable as a PDF from the Wilhelm Imaging Research web site.

Of particular note, the Display Permanence Ratings for the Epson UltraSmooth Fine Art Paper when displayed under regular glass rates at 108 years which jumps to 175 years when displayed under UV absorbing glass. That paper ink combo rates over 200 years under dark storage.

The highest color rating was for Somerset Velvet with the PremierArt spray coating which extended the permanence to 166 years under glass (without the spray coating, Somerset Velvet rated 62 years). Epson’s Watercolor Radient White paper came in at 118 years under glass and 236 years under UV.

However, what is stunning is that when using the new Advanced B&W Mode when printing B&W images, the print life is substantially increased! Epson UltraSmooth Fine Art Paper when printed using the B&W Mode increased its permanence rating to over 205 years under glass and a truely impressive >300 years when under UV glass. Epson Enhanced Matte Paper rated at 325 years under just glass!

A note from the PDF explains the huge jump in permanence for the Advanced B&W Mode is due to the fact that primary ink usage with the B&W mode is the 3 highly-stable carbon pigment based black inks that largely replace the cyan, magenta and yellow inks. These carbon pigment black inks are extremely stable.
