I’ve been looking for a new laptop and trying to find something that has an 8-bit screen, i.e. something that will give me print quality color proofing. You’d think that would be an easy task given the number of high-end laptops on the market these days, but alas no. My first thought was of course an Apple MacBook Pro – you’d think that would do it right? Wrong.
Apple, in their great wisdom and cost cutting drives opted to use a single light source (white) for their new LED screens. And while they may look nice and glossy, they still use dithering to create the illusion of a full color pallet. Pretty much all laptops on the market (with a few exceptions listed below) use 6 bit color output. Meaning they only produce thousands of color, not millions as many of the manufacturers claim.
The way they do this, is through a technique called dithering. Dithering uses two adjacent pixels displaying two separate colors, to create the illusion of a third color. It’s a way of tricking the eye, which is fine for general use, but if you need to see the true colors of your designs or photos, you need to see millions or colors, not thousands.
