When printing a file, you can never be certain exactly how your colors will print. The blue you choose on your computer screen may not match what is printed (maybe its darker or lighter or more green when you print it).
Have you heard of CMYK? That stands for Cyan, Magenta, Yellow and Black (why black is a K, I have no idea). Each time you print, you are combining those inks in different ways to achieve each different color. This can lead to the same color looking different on different printers.
Pantone has a special ink for each of its colors, so that no matter the printer/paper, your brand color will always be the right color. It's more expensive, but your brand will have color consistency.
When I saw this pack of 100 Pantone post cards for $20, I just had to get it.
I might do something like this and just frame the postcards.
Jessica from How About Orange turned her chips into magnets.
There are so many Pantone products out there and I want to own every single one: toothbrushes, folding chairs, stools, mugs, flower pots, rubics cubes, phone covers, mouse pads,messenger bags, bikes, luggage tags, and salt and pepper shakers.
Can't wait until I figure out what to do with mine. Hmmm...this might be a project I have to wait on until I get a bigger living space.
