The main difference between CMYK and RGB color models is how they create colors. CMYK is used for printing and uses cyan, magenta, yellow, and black inks to produce colors. RGB is used for digital displays and combines red, green, and blue light to create colors.

ANSWER----Follow the instructions given blow to change RGB color to CMYK color in photo shop CS2 ---1) Open photo shop CS2 ---> 2) make a new document (or open the existing one) --->3) Go to Image ---> 4) Mode ---> 5) CMYK Color -------> Finishnow check your document, you will see your document color has been changed from RGB color to CMYK Color.... EndsSo enjoy with CMYK colorsHope it helpsCheers--------------------------------
RGB is color model and is suitable for screen. All colors in RGB are made from 3 primary colors Red, Green and Blue. There are also other color models like CMYK which is suitable for print. You can convert RGB to CMYK and vice versa in Photoshop.
CMYK is commonly used for printing because it can produce a wide range of colors by mixing cyan, magenta, yellow, and black inks. This model is effective for printing color images and text accurately. However, other color models like RGB are better suited for digital displays. Ultimately, the choice of color model depends on the specific printing needs and requirements.
CMYK is used for printing because it is a color model that uses four ink colors (cyan, magenta, yellow, and black) to create a wide range of colors by mixing them together in varying amounts. This allows for more accurate color reproduction in printed materials compared to other color models.
The underlying color model in Photoshop is neither RGB nor CMYK but LAB. It has the widest gamut, which means it can hold more color values than any other model. Of the two other models, RGB has more color values than CMYK does. When you convert from RGB to CMYK, the program first "maps" the RGB values into the LAB colorspace. It then maps the LAB values into the CMYK colorspace. Now, for REAL entertainment...take a pure RGB blue, or a pure RGB green, and attempt to map it into CMYK colorspace. It doesn't work at all. Red maps fine, but the other two go straight to hell.
By "Pantone Color," you must be referring to Pantone Solid or Pantone Spot Color, because Pantone is the brand of a private company that sets the international standard for print colors. "Pantone" does not indicate that something is not CMYK.The mentioned company, Pantone, produces a swatch book called Pantone Bridge, and has the spot color on one column, and the CMYK process color on the other column so that you can see the color shift between solid and CMYK, as well as the CMYK breakdown. These swatch books are available online or in a local graphics supply store.
RGB has a larger gamut than CMYK. In order from small to large: sRGB, AdobeRGB, ProPhoto RGB. The largest of the CMYK gamut is GRACoL.
CMYK stands for Cyan, Magenta, Yellow, and blacK, which are the four colors of ink used in standard color printing. A CMYK code is a set of four numbers representing the proportions of those four colors of ink, thus defining a color to be printed.
If you want to convert a DIC color to a Pantone color, you must calcuate the CMYK value inside a graphics program such as Photoshop. Once you have the CMYK value you can convert the color.
In the CMYK color process, black is produced by mixing cyan, magenta, and yellow inks together, ideally resulting in a rich black, though it often requires a separate black ink (K) for depth and detail. In contrast, the RGB color process generates black by setting all red, green, and blue light values to zero, resulting in a complete absence of light. This fundamental difference arises because CMYK is a subtractive color model used for printing, while RGB is an additive model used for digital displays.
CMYK refers to the four inks used in some color printing: cyan, magenta, yellow, and key (black)
