otm 8 under development

Autumn this year otm 8 will be released. This edition contains additional functionality, for example, enhanced support for ttc/otc fonts, the option to edit the stem-snap arrays and stdhw values in the cff Header, and also trackpad gestures.

For the ttc/otc support the TrueType Collection Editor has been added. If one opens this tool, one will get an overview which tables are contained in which ttf font and which tables are shared. The window has a scrollbar to display all ttf fonts even if the number is very large. Also included are options to share tables with drag and drop, or to change a table and apply these changes to all fonts which share this table.

Those who purchased otm 7.9 in 2019 will be entitled to receive a free upgrade to version 8.

New: dtl OTMaster 7.9

The previous retail version (6.3) of dtl OTMaster was released back in the spring of 2016. A lot of functionality has been added since, especially developed for the internal font production at urw Type Foundry and the Dutch Type Library. The current otm version is already 7.9 and an overview of the extensive new functionality can be found below.

The initial plan was that version 8 would be the next retail version. However, the conversion from otf to ttf and vice versa, the handling of the ufo 3 format, and the development of the updated manual takes a bit longer than planned. Especially since the typo Labs conference in Berlin last April, we received quite a number of requests for a new otm version. Therefore we have decided to release version 7.9 first. Consequently this version comes without the otf to ttf conversion, ufo 3 support, and without an updated manual.

However, because of these limitations we lowered the price for otm 7.9 to €199 instead of the standard €255: please note that this is a one-time-only discount. Owners of version 7.9 will be able to upgrade to version 8 (scheduled for the first half of 2019) for only €25. An upgrade from older versions, for example 6.3, to version 7.9 costs €50.

otm 7.9 is available for macOS, Windows, and Linux. The macOS version has not been notarized by Apple for Gatekeeper yet: consequently, when starting dtl OTMaster for the first time, the right-mouse button (or + click) has to be pressed to open the application. Of course, alternatively the settings for allowed downloaded apps in the ‘Security & Privacy’ section of the System Preferences can be changed.

New: dtl LetterModeller 5.8

A new version (5.8) of LeMo is available for downloading now:


Prior to the official release of FoundryMaster in a couple of months, the glyph-editing functionality has been revised and above all simplified in the latest beta version of this major font tool. The ‘shift’ (pointer) mode has the ‘quick-mode’ functionality integrated now and this implies that it is not necessary anymore to use a three-button mouse*: all editing functions work with shortcuts. Because LeMo contains most of the editing functionality of FoundryMaster, this new approach also works for this application now. The downloads above contain the ‘LeMo_pointer_tool’ PDF, which provides an overview of the new shortcuts.

Please note that the interface of LeMo shows some legacy problems, especially when it comes to the multiple layers. In the course of time more and more functionality has been added to different base structures and this is far from easy to change. Instead of focussing on this issue, the emphasis in the development of LeMo will be on the investigation of how and to what extent the tool can become self-learning. Jürgen Willrodt and Frank E. Blokland will (try to find time to) focus on applying neural networks in the coming decade(s).

* The main reason for the somewhat unusual three-button mouse functionality was a complexity with Qt under Linux, which is used for the development of the tools.

dtl and urw at typo Labs 2018

Also this year the Dutch Type Library and urw Type Foundry were present (for the third time) at the typo Labs conference, which took place at the Umwelforum in Berlin from 12 till 14 April 2018.

During the ‘Type, Technology & Design’ hands-on session on Friday the 13th of April, Jürgen Willrodt and Frank E. Blokland especially focused on the integration of OTMaster and FoundryMaster in workflows based on, for example, Glyphs or RoboFont. After all, combining the unique functionality offered by different font tools can ease and speed up production matters considerably.

A new program that was introduced at the hands-on session is gposMaster. As the successor of KernMaster, it combines auto-kerning with several editing options. Like OTMaster and FoundryMaster, it will become available for macOS, Windows, and Linux end of 2018, or otherwise at latest early 2019.
