[alt-photo] Re: Epson 3800 Ink Expiration Date and Epson Driver

[Marek Matusz]

Amy,

Looking really close I can see that both sets of test prints show some banding, although it is more pronounced in one set (the one that you tweaked the driver settings). Maybe the tweak should go in the opposite direction. Just out of curiosity, some of the squares show much less banding, or almost none (at the same grey level). Are they diifferent colors?

Maybe you have overadjusted something in the settings? I can't remember if there is a reset to factory settings thing on the printer head? It might be worth a while to get a second opinion on the printhead testing and adjustments. Somebody else might spot something that you just glossed over and now it is fixed your mind as "good".

I have been using that printer for over 2 years now, never had touched any adjustments and since switching to QTR rip as driver life has been so simple, perfect negatives every time.

However, they (Epson) actually use expired inks all the time with no ill effect. Currently, I am printing with several expired inks—some of which expired last fall. So, now I'm wondering if there is any correlation between ink freshness and venetian blinds or even UV sensitivity. Epson could not address this issue, especially since I'm printing on Pictorico and not an Epson media.

And, when I tweak the settings under Advanced Media Controls in the Epson driver (as originally recommended by Epson and several folks on this list), it appeared to eliminate the venetian blinds, but then I experience other issues like the shadows blocking up. Recently I decided to print 1 PDN Color Density Range Palette with those same Advanced Media Control settings used to combat venetian blinds and then printed 1 PDN Color Density Range Palette withOUT the Advanced Media Control settings applied. Both were coated, exposed and developed according to my standardized time for pt/pd BUT the final print results are drastically different (BTW, each CDRP was printed with a Stouffers 31 step-tablet which reproduced the same in each). The CDRP printed with the Advanced Media Control settings reveals no paper white (looks way over exposed) and there is micro-banding; these differences are not detectable in the negatives themselves.

The New Busy think 9 to 5 is a cute idea. Combine multiple calendars with Hotmail.
