Pretty cool diagram, right? You can just about put it any number and you will get any color. I guess that’s why there is over 16 million colors!
How do you know when to use RGB? It’s short and simple. If you’re going to be doing something digitally, use RGB. There are no two types of colors, but they can be achieved. A digital monitor is made up of tiny unites called pixels. Millions of pixels that make up your colors. The RGB scheme has a greater range of colors than CMYK, which you will find out in a second because it has a full range of colors. You are very limited with CMYK. However, RGB will NOT always print out looking out on screen, and here is where CMYK comes in.
So what is CMYK? What does it stand for? For simple terms, CMYK is used in the printing world. CMYK stands for cyan, magenta, yellow and key or also known as black. These four colors are used strictly for offset printing. CMYK is standard in the agency world. We use it a lot when we print out brochures, stickers, flyers…the list could go on. I know it do not make sense but the colors look much better when printed. When you mix the colors though, they all produce white, pretty interesting right?
There are a select number of printers that can print RGB but they are extremely expensive and not accurate. While some could be used for “practical” reasons, when you layer RGB on top of other colors that are so close to each other, it produces even darker colors. Inks can only absorb so much and as we read before our eyes see them differently. However, when you have to print on different materials (stickers, photo paper, vinyl..etc) that is why you have to use CMYK.
Is it important to convert your files to RGB to CMYK, yes and no. A printing company could do it but you will be in for a surprise when your work comes back looking totally different (you will see an example shortly). Your color change from RGB to CMYK could be extremely dramatic. Almost looking dull and then you will not be happy with the results. Most printing places though require you to make your file into CMYK. My recommendation, that I have for sure learned at this digital agency since I do a lot of print is to start your project in CMYK if you know that you are making a brochure, business cards, stickers, flyers. There are crutial times where you have to use specific brand colors like an example, we have specific colors that work for RGB and CMYK because they know they will look good no matter how they are printed. However, I am not saying print in RGB, print in CMYK and save yourself the pain of having to go back into your file and transfer everything into CMYK – it can take hours (I’ve learned).
