I am looking to design in color mode ‘bitmap’. I don’t understand the use of the color mode bitmap. When and how can I use it?
It can be said to be an (old) alternative to vector. I have used it for some very old logos and drawings, but more recently in signatures. It is not vectorized, and not anti-aliased, so it needs to have very high resolution in order to not appear pixelated.
It can only have one color. If you place a bitmap colored file in InDesign, you can actually change the color there. Which is quite handy especially for signatures.
