Telling The Difference Between RGB And CMYK In Color Mixing

By Maryl Joop


Why is there a distinction between RGB and CMYK in printing? If you print, or are learning to print, on the web, you've likely had the lesson pounded into your head with a hammer that you need to make sure that your colors are set to RGB-red, green and blue.

If you don't do that, all your colors will skew and you have no idea why. If you print on paper then you've heard that the reverse is true.

Cameras have escalated to a high enough quality that taking a picture with the right camera will beautifully capture a realistic version of the painting itself. What constitutes the right camera you ask? Maybe when you think of taking a picture of it, you turn to your smart phone, or your sleek, pocket-sized camera that you take with you everywhere.

Although these do a good job of capturing memories and things in the moment, they are not the best cameras for capturing your painting. What's you will need is an SLR camera. An SLR is that large, chunky camera with telescopic lenses that you see some people with. They are the ones you typically set on tri-pods to take nice pictures.

This is due in large part to the specific need web designers are capable of fulfilling for both small and large businesses. Take Salt Lake City, for example, which is teaming with enterprising and established businesses, all of which are looking to grow and advance.

These are the basic colors of the spectrum. You cannot subtract anything from these light mixtures; you can only remove light, which creates the color black. On the other side of the spectrum, white is the combination of every color in the spectrum. Should you combine red, green and blue in this model, you will create the color white.

The color changes because the light is becoming more complex. As you combine only one or two of these three colors, they will create more colors to choose from. Interestingly enough, when you combine blue with green, you make cyan; blue and red create magenta, and green and red make yellow. Combinations of these three colors form the first three colors of physical print media. CMYK works as our physical print media. Unlike light, when you print colors together, they away from the colors complexity.

Instead of adding together to add brilliance, they degenerate into lower color forms that are darker and colder. This is why CMYK is called a subtractive color. Cyan, magenta and yellow are the most complicated basic three colors. In light, they are just one step away from white. When you combine them, they can form nearly any color by slowly deconstructing in controlled ways. Combining all three of these colors does not make black however.

This difference makes it hard to capture what you want to capture. An SLR uses a system of mirrors to see out of your lens. This makes a difference in the quality of the pictures you take of your paintings. To recap, an SLR takes better quality pictures of your art with a larger sensor, combined with a high number of megapixels and takes a picture of the things you're looking at.

You need both for your artwork. Alphagraphics specializes in printing quality pictures in Ogden. They provide a wide variety of printing services to help you reproduce the paintings that mean something to you at an affordable price.
