DPI, PPI, RGB, CMYK—these are all hyper-specialized terms for graphic designers, and they relate to the resolution of images and clarity of color. Each one is massively important to the industry and directly responsible for trillions of dollars in profits for businesses all over the globe.
CMYK, in particular, is essential to physical branding, and every prospective graphic designer must master it. Here is what you should know about the CMYK color space.
CMYK vs. RGB
The common mistake most people make when learning CMYK is conflating it with RGB. The two spaces of graphic design are far more different than similar. The RGB space consists of red, green, and blue colors. These are native to electronic screens. Basically, designers use RGB when working on digital objects and imagery.
However, when people print RGB images, the colors must convert to CMYK. Cyan, magenta, yellow, and key (black) comprise this space. These hues are what printers produce when creating printed materials.
Importance Within the Graphic Design Industry
How do graphic designers use the CMYK color space? During printing, a process called subtractive color profiling occurs in which brightness-reducing ink layers onto white images. This eventually produces your preferred colors.
So when dealing with RGB files, graphic designers must carefully convert images to CMYK for proper four-color process printing. They must ensure their RGB space utilization is good quality so that the color doesn’t get lost during the conversions.
Preventing Dull Conversions
This part is quite technical, but the process is how designers successfully convert RGB files to suitable CYMK images. They start by saving illustrator files into EPS while still in RGB mode.
They then open said file in a program, such as photoshop, and select CMYK color mode with 300 DPI. This method minimizes color loss, which is essential since the file can no longer undergo edits. Additionally, businesses use heavy-duty label printing to maximize the clarity of printed materials.
Ultimately, what you should know about the CMYK color space is its importance in advertising and making profits from said advertisements. Additionally, this color space is crucial for the many individuals who call graphic design their career.
