Thanks Dana for the info.
However, since I ran out of ink and GO, I placed another order today (June 6th) along with a separate 220ml bottle of G.O. since it seems to go 3 times as fast as the others. Not to happy with the system now. Maybe the printer is putting out too much ink, but no way to really tell. It only does the pump-up when I call for it to print, otherwise it is quiet like the other printer (Same model 3880). I don’t see any leaks present as I’ve had the carts out so many times for refills. The maintenance cart shows 14%, but it has taken a lot of power cleans too as I had a lot of yellow stain from the initial OEM ink charge left in the whites. I dunno.
From your charts above, that black line (Starts by the yellow.) I’m guessing is the G.O. (LLK) line? That’s the one that I think drank all my G.O. ink up. No doubt it might have taken a big hit since I had to do maybe 5-6 power cleans to get rid of that yellow prior to learning I could flush it out with just a yellow print. I see Qimage Ultimate is also allowing for individual ink cart flushings now as well (Aside: I’m using QTR, but have tried Qimage to see a sharpness increase, which it seems to do.).
I also sent Wells a JPG today when I queried if you got the envelope that shows the issue I have. The white type with my name is dark and almost black in the print where the LCD screen under it is white. (Excuse the slow shutter speed of 1/8 second since I needed the LCD screen alone and not with the flash bouncing off it.).
If USPS doesn’t get the images to you by next week (Big yellow legal (8.5x11) stamped envelope.), I guess I’ll have to go back to the commercial lab and have them run another set that shows their sharpness on Epson Luster than I cannot achieve with the K7 and my printer with the same images.
Really is frustrating! Okay, very expensive too.
I do know in this mess that the Canson Platine Rag and the extinct Ilford Prestige Gold Fiber printed with Photo Black seems sharpest so far. I did have to throttle back a lot on the curves I got off your site though. Seems Step-21 (Blackest) had ink sitting on it waiting to dry coming out of the printer. Seemed to throw off the i1 PhotoPro 2 head as well. Ink dried pretty quick though, maybe 1 minute or so. Still looks a bit carbon blackish sitting on the Canson RC papers though.
I also see from your charts above you are running around the 40-60% mark in ink density. I had to pull the Ilford GFS with Photo Black and GO way down to <30% and it’s beginning to look much better in tonal range, although my Cyan is always high for some reason. Maybe I got a flooder printer? I’ll attach my QTR curve for that paper which seems best so far in the mess, although still isn’t as sharp as the labs. Hopefully it got through as I also had to uninstall Adobe Flash again to get it to accept the JPG upload here. Ugh!
