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.
4/0 – Full Color Front, Blank Back
4/1 – Full Color Front, black ink Back
4/4 – Full Color Front & Back

Typically spot UV is prepared for printing by including a separate mask file usually in black and white with black indicating where the UV will be placed. This mask file lets the press know where spot UV should be applied. In most applications the spot UV area in the mask will match a design element underneath it exactly so that the design element below is covered in gloss. Blind spot UV is the process of having the spot UV mask design element exist in the mask file only as a creative effect. For example having a logo or pattern in spot UV that is applied over an area of the ink without that same logo or pattern (a solid colored background for instance).
