Printing with 'blue dots'
Hello. When I print my cards I noticed that the background has little blue dots. They are everywhere on my page including my text. I usually create my file in InDesign and then export it as PDF file and then print it.
I tried printing it from InDesign, from Illustrator and still no change. I am using illustrations that I vectorize in Illustrator by image tracing high quality, I don't know if this has something to do with it.
Has anyone any idea what this could be?
Thank you.
