Otherwise, you risk getting strange, muddy or simply incorrect colors back from the printer. RGB stands for the independent color channels that make up the digital light display: red, green, and blue. This is true even if an image is currently in the CMYK color space, because the devices that likely captured that image — digital cameras and scanners — operate in RGB. They sense and store red, green, and blue light instead of physical pigments.
While progress in flexibility has been made, CMYK conversion is still required when sending out your artwork and images for commercial printing. And converting everything to CMYK before you send your files to print can also guarantee that the printed results match your expectations.
However, on print materials, colors are produced differently from how they are made on a computer monitor. Layering RGB inks on top of or close to each other produces darker colors because inks can only absorb and reflect different colors in the light spectrum , not emit them.
RGB colors are already dark to begin with. This makes it difficult to produce lighter colors such as yellow or lime green as adding RGB colors will invariably result in much darker hues.
Using a CMY color model provides a workaround for this problem as cyan, magenta, and yellow are lighter than red, green, and blue.
Yes and no. However, we recommend starting your project in CMYK or at least converting from RGB before you send it in for printing for a few reasons. The letters in the name stand for the colors mixed together to create more colors. Both methods can produce a wide range of visible colors, but they have fundamental distinctions between the two methods. CMYK is used for printed media, while RGB is used for monitors, televisions, projection, and other light-based display technologies.
CMYK, which mixes four ink colors, uses subtractive color. If we mix all the colors together, we end up with black, gradually subtracting lightness as we mix more paint or ink. For pure white, we must leave the paper unprinted, as nothing can be whiter than the paper it is printed upon. CMYK specifically, and subtractive color in general, has some weaknesses. Black is added to CMY in order to produce rich blacks; without a dedicate black ink, the best we can do is a muddy dark grey.
When white light reflects off the colored ink, certain wavelengths are reflected more prominently than others. This is interpreted by our brains as color. Black is the absence of color. This can be shown in the picture below. Certain colors that can be displayed on a monitor in RGB cannot get printed on a sheet of paper, which is why the colors can change. Even after converting to CMYK, you may notice color shifts in the colors, which might require a lot of editing to correct.
Or, it could result in you accepting that the colors will be off. If you start with the CMYK colorspace from the start, this will eliminate any possibility of problems with mismatching colors from your display to your print. When creating documents for print, it can save a lot of time and frustration by making sure your software program is set up for CMYK before you start designing.
In the same window, choose which specific CMYK color profile. We recommend GRACol because this is the color profile that our presses will print in. This will maintain the resolution of your file.
Now the file is ready to be saved! JPEGs into a file for printing.
