4 Color Large Format Poster Company Printing

The use of color on big prints such as large format posters determines how your design will look like once printed.of your it is important to ensure the quality of colors . Printing companies use a 4-color range in producing their products. This color scale, also known as CMYK, makes use of Cyan, Magenta, Yellow and the Key color (black). This becomes the base colors used in modern printing industry. Specific combinations of CMYK colors result to its color mode counterpart, RGB (red, blue, green):

• Magenta + Yellow = Red
• Yellow + Cyan = Green
• Cyan + Magenta = Blue

Although CMY combination results to a color near to black, the key color is nonetheless added to the CMY range to conserve the use of the three colored inks.


CMYK is specifically used in printing while the other color gamut, RGB, is used in computer monitors and TV screens. RGB absorbs light, while CMYK reflects light. Electronic monitors need to "absorb" light to display colors. On the other hand, paper (or any other printing stock) simply reflects available light. Thus, when RGB is utilized in prints, it appears darker because it absorbs light instead of reflecting it. Therefore, CMYK works with specific color wavelengths rather than dealing with the amount of light, making the 4-color process ideal for printing on paper or card stock.

There are instances when you created your poster design using a different color mode on your graphics editing software as opposed to the one being used by the printing company. As a result, the color of the final printed product would not appear the same to the one on your original design. Therefore, in order to prevent this from happening, you must check first whether the company prints using the RGB or CMYK color model. If the company prints using RGB, then you must convert the color mode in your design software to RGB; same thing goes for the CMYK mode. This way, you can guarantee to receive ready-for-printing color quality of your design.
