To reproduce the spectrum of colors we blend 4 main colors: Cyan, Magenta, Yellow and Black. The printing term “4/0” refers to these four process colors on the front, and no color (blank) on the back.
1/0 – One color ink front, No print on the back
1/1 – One color ink front, One color ink on the back
Matte White or Color Card
[Glossy] Lamination or Coating ( Glossy, UV Coating, Matte, Aqueous, etc.): Most cards are finished with some sort of coating to improve the look and durability of the card once it is printed. Depending on the manufacturer and price, you may have a few options to choose from. Glossy UV is a very common option, and provides a glossy, reflective-type look to the card face. Aqueous coating gives the face some sheen, but not nearly as much as UV gloss coating. Matte is the standard looking paper-finish look.
