hi Fuzzbuster,thanks for your comments. I knew that Epson has three popular inkjet heads DX3,DX4 and DX5. DX3 use water-based pigment and dye ink. For DX4,DX5, it is Eco-solvnt ink.
Eco solvent ink is popular due to it has advantages which water-based ink(high resolution,less smell) and solvent ink(for outdoor,some outdoor media is printable) have. The solvent print head like Xaar, Konica, Seiko, Spectra,etc. Comparing with the resolution between them, you can find DX4 is much better, firstly the PL(pico liter) is smaller( i know you do not aggree), and the resolution is much higher than solvent print heads.
second, less smell did not mean no smell, not stronger like solvent ink. it is one of environmental friendly inks. You can find some eco printer is smaller than solvent printer. eco printer can print the media used for both indoor and outdoor. i am sorry if i make any misunderstanding. but hope to exchange each others opinion,and improve my knowledge of eco ink and printer.
