Do the Epson UltraChrome K3 inks have less outgassing than the previous Epson UltraChrome Inks?
The new Epson UltraChrome K3 inks have about the same outgassing as the previous ink set. So, depending upon the environmental conditions, Epson recommends that you let your prints “outgass” into interleaving papers (Epson Singleweight Matte, Doubleweight Matte, and Presentation Matte all make great interleaving papers) for at least 48 hours before framing.
Please note: You must replace the interleaving paper at the 24 hour mark with a fresh sheet. Proper framing procedures must be used, including no contact between the print and the inside of the glass or UV acrylic.
