Is white Considered a color?
Not Typically. Because white is the default color of paper, it is simply recognized as the absence of ink.
What is a proof and why is it important?
In printing terms, a proof is a one-off copy of your documents after all modifications and printing setup process have been completed. It is your last, and best, opportunity to make sure that your print job comes out the way you envisioned. By carefully inspecting the proof, you can help ensure an accurate, flawless delivery of your print job the first time.
why do the printed colors look different than the colors on my screen?
In short, printers and monitors produce color in different ways. Monitors use the RGB (red, green, blue) color model, which usually supports a wider spectrum of colors. Printers use the CMYK (cyan, magenta, yellow, black) color model which can reproduce most -but not all- of the colors in the RGB color model.
Depending on the equipment used, CMYK generally matches 85-90% of the colors in the RGB model. When a color is selected from the RGB model that is out of the range of the CMYK model, the application chooses the closest matching color. Programs like Adobe InDesign, Photoshop, and Illustrator will allow you to choose which color will be replaced; others may not. We'll provide you with a proof to ensure a "what-you-see-is-what-you-get" final product.
