PrintingCenterUSA requires Print-Ready PDFs from customers for print projects. One of the most important qualities a Print-Ready PDF has is that it is in the CMYK color mode. With that being said, one of our most frequently asked questions is: How practise I catechumen from RGB to CMYK? That's what we're going to detail for you today.
Earlier we get into the technical how-to's, it is important to have a grasp of why your files being in CMYK is so of import. When preparing your files for a print project, the colour manner of all files is something you should constantly be enlightened of. This goes for your images, graphics, and final PDFs. Your product should be designed in the CMYK color mode whenever possible.
1. What is CMYK?
CMYK stands for Cyan, Magenta, Yellow and Key (Black). If yous do not relieve your product in CMYK, PrintingCenterUSA volition automatically convert your design from RGB. RGB stands for Cherry, Green, and Blue—This is the colour mode you encounter everything in when viewing on all monitors. Your telephone, computer, tablet, tv, etc are all RGB.
Color printing is besides known equally iv color printing, full color printing, process printing, and CMYK printing. Four-color printing involves the separation of all colors into four different color values (Cyan, Magenta, Yellow and Black).
ii. Why Does the Colour Way Matter?
CMYK Printing is an additive color process utilizing ink or toner. RGB is a subtractive color procedure that is based on light. When y'all add physical layers of colored ink on meridian of each other, they mix 1 mode. When you add layers of colored light together, they mix in a completely different style. For example, in the epitome below you can run across that when all of the RGB colors add together together in the middle of the RGB diagram, white is created. When all of the CMYK colors add, they create Central (Black).
When RGB files are converted to CMYK to print on a four-colour printer, there are generally color shifts. Commonly these shifts are minor, only they can be an issue, especially if your projection is color-sensitive. Similarly, if you upload a CMYK epitome to the internet, you may also see color shifts (Example Below).

When you save your images and graphics from the net, y'all must recall to catechumen that prototype to CMYK (and check that it'southward a loftier enough resolution, only we'll salvage resolution for some other day). This is due to the gamut of CMYK, and more than specifically PrintingCenterUSA'south specific color profile, being smaller than the RGB gamut. Gamut refers to the maximum range of colors for a color space. RGB has a much larger gamut that CMYK, which is why at that place are colour shifts when converting from RGB to CMYK.
