Yvonne,
I am on the newer side here myself. So my experience on this site is limited in some ways.
That said it looks like you are getting banding in your processes even before you would go to print.
Banding happens when the digital equipment, the FAA serves, the cell phone you are using, etc and the combinations
of equipment dont have enough data to stop banding from happening. Banding is a splotch of an area where
the image's gradient fails. Instead of a gradient you get a flat one hue, one tone area. I mentioned the FAA servers because
I think I can see banding in your images on their servers, but lets make this perfectly clear THIS IN NO WAY IS FAA's FAULT.
This only has to do with your equipment.
And perhaps someone here with more experience will correct me about this or confirm that your processes are
creating banding.
We all need plenty of computer power, whether in our cameras as mega pixels, or in our computers as
processing power.
