Extraordinary impact and visual conspicuousness. Poipoi is a super 3D sans family for posters, logos and all display. The basic idea is not a brand new. The Stacking type system has been used since before wood type age. As you imagined, colored wood type(woodcut), many other engravings and contemporary printer machine print many colors separately with different printing plates for each color.
Poipoi uses the same system for 3d effect.
Please use Photoshop or Illustrator, or your favorite graphic design apps that can handle layers.
Layers are the printing plates of wood type. You should be able to change text color for each layer.
Poipoi “Standard” style is the base of this font family.
You can add effects by stacking Highlight and shadow layers.
Stacked layers in different color make the text in 3D.
