The SVG format requires Photoshop CC 2017 or Illustrator CC 2018 (or newer)
The Regular TTF format works universally.
Hackney is entirely hand-painted sans serif. A raw, bold, condensed font, with brushy imperfections and an earthy realism.
SVG fonts or colours fonts are a great new format, which makes it possible to add loads of detail and texture not possible before. Hackney SVG keeps all the incredible definition of the real painted strokes as a transparent texture, so it gives you a proper hand-painted effect, without you having to do anything (or go near paint). SVG fonts work just like normal fonts, but allow so much more customisation and look hyper-real. They can be used in any colour and on any background.
