I have resized document in preparation for print and used lanczos 3 (non-separated) and after a 10 seconds of crunching the numbers, my imaged changed and now has a thin horizontal band which I cannot remove.
I have tried the immediately obvious which is close the image and re-open; it's still there! I have gone back to my original and it's not there!
Any help/ideas would be most welcome. I will send it for printing anyway, but I fear it's highly likely that the print will contain the horizontal line.
Thanks!
