How to Avoid Blues Turning Purple
• In the printing world, blue is close to purple in the CMYK color spectrum.
• When using equal parts cyan and magenta, it will print purple even though it appears blue on screen.
• The best way to avoid an undesired purple in your printing design is to utilize a small percentage of magenta when a heavy percentage of cyan is used.
• We recommend using 30% more cyan than magenta to avoid turning purple.
