Think of printers and printer paper as paints and canvas. The better the paints, and the better the canvas, the better the finished result.
If you’re using a cheapo home inkjet printer, and printing 20lb. bond with a 90 brightness, your printed images will look terrible. They’ll be grainy and faded.
However, if you have your images printed on a color laser printer, on 28lb. or 32lb. stock with a 98 brightness, your prints will sing.
Trust me. It’s how I make my living.
