print horizontal lines in areas of transparency

[AutoDidatta]

Bye to all,
I created transparent ellipses that overlap. in the press preview everything ok, in the final pdf instead appear horizontal lines. My goal is to print a banner of 1m x 5m. I tried to increase the resolution and play with the print settings but I don't fix it. find the defect in the attachment.
thanks for the support
