Spot Color printing is best suited for printing that requires up to 3 PMS colors.
Full Color printing uses the four process ink colors: cyan, magenta, yellow and black, (CMYK) and combines these colors to produce full color pictures. It is best suited when corporate logos use or exceed more than four colors.
Make margin on the layout that is 0.5cm from the edge all the way around.
Now create your design with the idea that the layout will be cut off where those guides are…. because that is precisely what is going to happen.
Make sure that any photographs or backgrounds that you want to bleed go clear out to the perimeter of the document.
