FontLab VI was created with variable fonts in mind. Liberated from the limits of the Multiple Master approach, FontLab VI offers support for an arbitrary number of masters that can be placed anywhere on any axis within the design space. In this talk, Adam will discuss how to start a variable font project in FontLab VI, transfer variable font data from other formats into FontLab VI, define axes, font masters and glyph masters, how to explore the design space and manage different master designs, how to draw and edit contours across different masters, automatically or manually create interpolation-ready drawings, and how to prepare variable font sources for production as OpenType Variation fonts and as static OpenType font families.
