Hello, 

I create a web app using basic viewer template. I have a ramp of color when is 0 is light color and when is 10 is darker color.  in my webmap is correct.

and if I print this image from my web map the ramp is correct. but when I print from the application, 0 is darker and 10 is lighter color .

and this is not correct

is there a bug?

How can I fix it?
