Digital BW, The Print

Hello. I am getting banding when I print with my HP 9800. I am
printing B&W with the photo grey cartridge. The results are great,
except for the banding. When I do print color, it also shows banding. It
does not show banding in every print, but I would say it does on a
frequent basis. I have tried new cartridges and it still bands. Any
suggestions? Also, can anyone advise using this printer to print BO? 
Thank you.

Hi Francis,

I also have vertical banding with my HP 9800. Don't know what causes 
it.  I called the HP rep, and she said it was the paper batch. which I 
don't believe, because the banding showed also with Ilford paper.

Black only is easy. Just add 4-5% of gaussian noise to the image to make 
sure the transitions are smooth and print with the option to use 
black/gray cart with the black cart installed. Some carts I've used 
showed some horizontal banding, and it's not like clogged nozzels, but a 
1 cm wide lighter area across the print few cm's from the rear edge of a 
super-B print. The last black cart I have shows this. The A4 prints are 
great, but can't print bigger prints, because of this banding. But I've 
printed some great super-B prints with other carts, so it is a hit and 
miss to get a good cart to print BO.

Hope this helps,

best

One thing still. I get prints without banding with grey cart using best 
quality setting.

Thank you.

Do mean Gaussian Blur ? Thank you.

No, I have Picture window Pro, and there you can add gaussian noise,  or 
PS Filter->Noise->Add noise -> distribution gaussian at 4-5%
