Converting to CMYK

CMYK (Cyan, Magenta, Yellow and Black) is the color model used by commercial printing presses. RGB (Red, Green, Blue) is the color model used by computer monitors and most domestic printers.

Many colors you create on your monitor (RGB) are not achievable using standard four-color process inks (CMYK). If you submit your files in RGB color mode, we will convert them before going to press which could lead to color shifts that you may not be happy with. It is always best to create your document from the start in CMYK format to ensure that you have a good idea of how your colors are going to print from the beginning design stages.

                        

Likewise, unless you plan on using spot (or Pantone colors) in your design, you should convert all spot colors to CMYK before submitting your files. Some colors look quite different after conversion!

 

 

 

 

 

Sometimes we place images from other sources not knowing they are RGB or contain spot colors.  Again, if not corrected prior to submitting files, the conversion may result in color shifts.   You can check the swatches in your design programs to see what colors are being used in the files.  If you have more than the 4 process colors, you will want to change them, unless you plan to use spot colors in addition to the process colors or if your design only includes spot colors.

A quick check of your ink swatches can save frustration and time on rework in the future!
