One centered dark band-is this common?

(1/2) > >>

Rocco Penny:
practice practice practice-
ok working on making a large print from a smaller image,
on doubling the size of the print,
this band appears down the middle all the way from one edge to the other

does this appear to be beginner's mistakes?
Is there a heading in my cs4ps textbook I should be studying?
OK thanks

Not sure what you are actually doing here... what method are you using to print larger?

- PS up-scaling?
- printer driver change?

Also, does it show with other images printed the same size?

Cheers,
Bernard

Rocco Penny:
hello, thank you,
yes,
cs4ps and upres in application
I had banding in another exposure after upres.
Only two exposures, both worst in the bright blue of the sky, and only when I enlarged them to two hunnert percent of native size.
On any paper, and worse on shinier paper
thank you for the time

Can you see it in the file itself after you uprez on the screen or only when you print it?  Is the print printed lengthwise?  It almost looks like a printing artifact to me ... as though the paper hit something and didn't move correctly.

Rocco Penny:
Hi thank you,
there is no problem with the original file according to my monitor, and smaller prints of the same image have no band. I'm printing 36x24 on a 24" printer.
I believe there may have been a problem with the paper advancing on the 1rst Hahnemuhle pr baryta print I made,
but surely not on the HP aquarella seen on my table above.
That same line, in the same place, appeared on each 1/2 way through the print job only when enlarged from 100% to 200%. I'd cancel the job at that point, but since the ocean and sunset are further toward the end, and the color is critical at the point where the sun hits the water, I just let it continue so I can see what the deal is.
I'll start over as the color is not what I wanted either.
The wasted paper and ink are becoming a concern as these aren't smallish images.
I appreciate your comments.
Thanks again,
Rocco
