EPS images blurry in ID

I bought 20 EPS line art images from Shutterstock to use in a book. But, all the images are pixelated. I got in touch with Shutterstock and they told me that the images are fine and the problem is on my side.

I also saved the image as AI, PDF, and TIFF, but nothing has changed. I have the View on Display, High Performance and still nothing. I uninstalled the program and reinstalled and still nothing. My project is stalling because of that. Can please anybody help me out? I’m adding one of the images in the Preview program on the Mac and it looks perfect; it’s only when it is in ID that looks jagged.

Many, many thanks!!

Preview of one of the EPS images. It looks perfect. Not like this in ID. Here you can see how it looks. I used Blending Mode, Multiply, but even without it, it is still blurry.]1]1
