Hi, The appearance of a gap before the letter T has nothing to do with kerning per se, but with my use of smallcaps and kerning. I solved my problem by defining a font feature and applying it with the \setff command as described on the wiki. \setuplayout[header=0pt, footer=0pt] \setupstretched[width=6.25cm] \definefontfeature[smallcapitals] [smcp=yes] \starttext \setuphead[subject][style=\setff{smallcapitals}, textstyle={\kerncharacters[.40]}] \startsubject[title={Properties of Blood}] \stopsubject \setuphead[subject][style=\setff{smallcapitals},deeptextcommand={\kerncharacters[.40]}] \startsubject[title={Properties of Blood}] \stopsubject \setuphead[subject][style=\setff{smallcapitals},deeptextcommand={\stretched}] \startsubject[title={Properties of Blood}] \stopsubject \stoptext On Mon, Sep 14, 2015 at 5:33 PM, Michael Guravage wrote:

Hi,

I am trying to use kerning in subject titles. \kernchracters works pretty good, but as you can see in the attached example, there is a gap before the Ts in Properties, and again in Praefatio and Praefationis. The \stretched command yields similar results, vis-à-vis the gaps.

If somebody can enlighten me how to properly use kerning in this situation, I'd be immeasurably grateful.

Cheers,

Michael
