Thank you Fred and Mike!
Nozzle check shows no broken lines.
I have third party CIS ink. The image below shows the range of colors from this ink. The drawing on the right is the original while the left one is printed on a premium luster paper with setting on Color Control, Epson Vivid, using ACDSee editing program. So far this is the only artwork that prints up in an acceptable way. And this is only so on this luster paper. No other artwork printed on any paper/setting come close to the original.
The soft proof looks exactly like the scan, which is very acceptable. Does this mean the error is with my printer? If so, does this printer issue affect all prints? As you can see, the image below, although not a perfect match, seems balanced in colors.
just as some background, the screen views in QU including the print preview are based only on your monitor profile. The printer profile is not considered for screen views. By using soft proof, the image is sent to the printer profile first and then back to the monitor: in order to show you what the print should look like when printed (think of soft proofing as a way to see what your printer profile is doing... but view that on the monitor). So a soft proof view, even though it is on screen, does take into account the printer profile so if a soft proof looks green, it's due to a bad printer profile.
Thank you for the information.
