Just got a brand new epson 1400 and bought a pack of JVC Taiyo Yuden Water Shield White Inkjet Hub Printable 16X DVD-R. i also got the cone ciss system for the printer as well. did the alignment thing and got it about as good as what my eyes could decide which was best. pictures on paper come out beautiful. however when printing on the dvd itself there are visible vertical lines running down the dvd. they are not bad but upon close examination u can see them for sure. they are about an inch apart or so. im printing with the built in epson dvd printing software. the one setting i changed was the spot where u pick CD/DVD premium surface. im sure its a setting that needs to be adjusted...i just dont know what. also they appear whether i use epson's ink's or the cone inks. TIA
