Banding on b&w ink jet prints

I'm getting horizontal banding on my b&w prints - especially noticeable in the black areas. I have already done about 5 nozzel checks and cleaning and 1 deep clean. Also did a print head alignment. Also switched the black carts. Those actions improved it a little but still can see slight banding in the blacks. Any additional actions I have not thought of would be appreciated.

 

Using a PIXMA ip8720 with 3rd party inks (the PGI-250 XL is pigment) and CANON Premium Matte paper 13x19. Also using the 'plain paper'/GRAYSCALE setting to eliminate all traces of color tints. I know the PGI-250 XL/'plain paper setting is normally used to print text but this is the only setting I'm using that does not produce green/magenta/cyan color tints on b&w prints. The prints are high contrast and a tad harsh but I like that look for what I'm printing right now.

So you see all nozzles fully firing cleanly?

I suspect that it isn't possible to make all inkjets exactly alike. Close enough for most people and most images.

 

For a large uniform gray area, very small density changes might be visible.

 

And maybe more visible in black and white than color.

Yes, there are no white lines running through any of the colors,b&w on the nozzel print out.

Do the test print to isolate individual nozzle problems. Since cleaning doesn’t help, you may need a new print head. Skips are obscured in actual prints due to overlap.

Print out a color reference image: see banding?

I recently had a similar problem with my Epson Photo Stylus 1400. I brought it to a Epson repair and he soaked the print head and it cleared up the problem. Otherwise I was looking at replacing the print head. It might be worth a try for you to have this done.

Has anyone printed that test file? I can't figure out how to do that.

Yes! What's the issue?

When I open the PrinterTestFileFlat.tif, the "print" option is grayed out.

I have Lightroom 6 as well as CS6.

Don't know what you're doing but all fine on this end. You unzipped it and opened it in Photoshop right?

Overlooked in this discussion is the OP's admission to using 3rd party inks. What does Canon know about ink formulation and performance, including atomization, penetration and dot gain, that others do for less?

Yes, NOW I unzipped it and opened it in Photoshop. Thank you. Operator error.

I printed it also.

I just profiled my 10 year old Dell 24" monitor with the Color Munki. The color patches are close but not perfect and the blue on my print is a little purple compared to the test file on the monitor.

I have the Epson Stylus Photo R3000 using Epson inks; Windows 7.

Thank you for your help.
