What is the difference between CMYK, RGB, Index, and Spot colors?
CMYK: Cyan, Magenta, Yellow & Black inks, make up the colors known as 4-color process. These colors are used in varying percentages to create the spectrum of colors for full-color reproduction in offset printing.
RGB and Index color modes are not supported in the offset printing industry. RGB (Red, Green, and Blue) allows a larger percentage of the visible spectrum to be displayed than in CMYK. The RGB color mode is dependent on light being emitted through red, green, and blue phosphors. Monitors, film recorders, and video cameras display color using the RGB mode. Index color is based on a palette of 256 colors. This limited palette is useful for multimedia applications and Web pages.
Spot color usually refers to Pantone® specified colors. The Pantone Matching System® assigns numbers to specific ink mixes that are printing industry standards. A Pantone® swatch book can help you chose an appropriate color. Don't judge colors by the way they look on your monitor, you'll be surprised how different the color looks once printed.
What resolution do I need for the best reproduction of photos?
Whether you are reproducing a photo in grayscale or full color (CMYK) In Adobe Photoshop's image size dialogue box, at least 300dpi (dots per inch) or more should be displayed. Remember you can't really increase the number of pixels per inch without a loss of crispness. So images must be scanned or created at your target resolution or higher. If you are unsure or are unable to scan or create your photos to the specs needed, please give us the original photos so that we can scan them in to the appropriate dimensions.
