I have made a logo in Illustrator. It is a very simple text logo where I have created outlines to turn it into a Vector. I also have made some small adjustments with overlays to remove part of the text (see picture). When I zoom in everything is perfect the way I want it to be, but when I save it as a PDF it suddently changes my design and make certain lines thicker and parts of the logo blurry.
Why is that ? I just want a clean logo that I can resize and use for different purposes.
In the second picture you can see that the I is thicker that the other letters but it is not that way in the first photo which is a screenshot of the illustrator file.
