The vast majority of printers for both home and commercial use employ a different color model from electronic display devices such mobile device screens and computer monitors. Computer monitors use an RGB red, green, black color model, suited for getting a wide dynamic range of colors of a dark screen.

Color in Process Printing

The color mode or image mode determines how colors combine based on the number of channels in a color model. Different color modes result in different levels of color detail and file size. For instance, use CMYK color mode for images in a full-color print brochure, and use RGB color mode for images in web or e-mail to reduce file size while maintaining color integrity. For example, a bright red color has an R value of , a G value of 20, and a B value of When the values of all three components are equal, the result is a shade of neutral gray.

The RGB color model is one of the most widely used color representation method in computer graphics. It use a color coordinate system with three primary colors:. Each primary color can take an intensity value ranging from 0 lowest to 1 highest. Mixing these three primary colors at different intensity levels produces a variety of colors. The collection of all the colors obtained by such a linear combination of red, green and blue forms the cube shaped RGB color space.

If we see an image, we see multiple combinations of color s. Every value carries information about the image and we can alter the values according to our requirement. The point is which value should we change for our particular requirement. If we talk about the color sensors present in a human eye, cones are the sensors responsible for color vision. However, blue cones are most sensitive. So these are our primary colors — Red, Green, and Blue. The word primary is widely misinterpreted that these three colors, when mixed in various intensity proportions, can produce all visible colors.

Depending on where and how the final result is displayed, one color space is always better than the other. Never fear these acronyms again! But to fully optimize your design, you need to understand the mechanisms behind each. Use the RGB color mode if your design is supposed to be displayed on any kind of screen. A light source within a device creates any color you need by mixing red, green and blue and varying their intensity. This is known as additive mixing: all colors begin as black darkness and then red, green and blue light is added on top of each other to brighten it and create the perfect pigment.

RGB vs CMYK: What’s the difference?

No, but a PDF workaround solves the problem

Агентство не может позволить себе еще одного скандала. Стратмору нужен был козел отпущения. Кроме всего прочего, Хейл был настоящим ходячим несчастьем, готовым свалиться на голову в любую минуту. Из задумчивости Стратмора вывел звонок мобильного телефона, едва слышный в завывании сирен и свисте пара. Не останавливаясь, он отстегнул телефон от брючного ремня. - Говорите. - Где мой ключ? - прозвучал знакомый голос.

Глаза Сьюзан сузились. Она терпеть не могла, когда он называл ее Сью. Вообще-то она ничего не имела против этого имени, но Хейл был единственным, кто его использовал, и это было ей неприятно. - Почему бы мне не помочь тебе? - предложил Хейл. Он подошел ближе.
