In the past two decades of having owned both inkjet and laser printers, I've noticed a common issue among laser printers. While high-end ink jet printers have always produce high quality photographic images that look great when viewed from any angle, the same cannot be said for laser printers: While they are getting close to photographic quality, the prints always seem to have an uneven shine to it which is a lot noticeable when viewing them tilted.
What is that "uneven shine" called? Have laser printer companies done research to deal with that uneven shine?
