CMYK

CMYK stands for cyan magenta yellow and blacK and is a color system used in the offset printing of full-color documents.

Offset uses cyan, magenta, yellow, and black inks and is often referred to as “four-color” printing. Monitors use red, green, and blue light instead, so they display images using a different color system called RGB. One of the great problems of the digital age has been matching colors between these two systems; i.e., taking a digital RGB image and making it look the same in print using CMYK. These problems are addressed by applications such as the Pantone Matching System.

Crop

To crop means to cut the pieces of an image that you don’t need.

Cropping differs from resizing because when you crop an image you retain the dimensions of the image. Resizing an image actually shrinks the image into smaller dimensions.

Duotone

Duotones are images that only display in two colors.

Like most visual techniques on the Web, duotones come from the world of print. In print, the more colors you use, the slower the production time and the higher the cost, so duotones were often an economical alternative. Duotones can also improve efficiency on the web by enabling the creation of cool-looking images with small file sizes. Duotones are made by first creating a grayscale image and then overlaying it with a different specified color.
