The Dutch Type Library (DTL) is a publisher of digital types which operates on an international basis. Established in the spring of 1990, it was the first of its kind in the Netherlands. The Dutch Type Library has set out to produce and publish types of the highest possible quality. This standard not only applies to the type designs but to their digital descriptions as well. The Dutch Type Library supplies principally all of the current digital formats, including PostScript Type 1, TrueType for Mac OS and Windows and, of course, OpenType.
In the second half of the 1990s, the programmers of DTL Germany / URW++ started programming DTL FontMaster, a series of (batch) modules for professional digital font production, which run under Windows and Mac OS. It was the first program of its kind on the market that automated the production of full featured OpenType fonts based on the Adobe OT SDK.
