Ever sent off a design with a perfect black, only to get prints back that look gray? ๐ค
Black is one of the trickiest colors to print, and picking the wrong one is a common, costly mistake for small businesses.
Here's the short version.
100% K (C:0 M:0 Y:0 K:100) prints with a single ink. It stays crisp and has no registration issues, so it's the right choice for body text and barcodes. On uncoated paper, though, it can look dark gray.
Rich Black (C:60 M:40 Y:40 K:100) layers all four inks for a deep, solid finish. Use it for large backgrounds and bold graphic elements. Keep it away from small text, because even a slight shift on press blurs the edges.
Never use 400% black (C:100 M:100 Y:100 K:100). It soaks the paper, won't dry properly, and makes registration a nightmare. Keep total ink under 300%. โ ๏ธ
One last tip: your screen can't tell these blacks apart. Turn on "Display All Blacks Accurately" in InDesign or Illustrator, and check Output Preview in Acrobat Pro before you export. ๐ฅ๏ธ
