# How to simulate a bold font if I only have a Regular Height TTF file?

How can I simulate a bold font if I only have a Regular Height TTF file?

I'm trying to use Ibarra Real font, but I have only Italic and Regular font files.

Using xelatex and a preamble like:

\usepackage{fontspec}
\setmainfont[Extension=.ttf,BoldFont=IBregular,ItalicFont=IBitalic,Numbers=OldStyle]{IBregular}


I can see it, but \textbf is the same as normal text.

Is it possible to modify font weight in latex?

In the name of all that is holy, please do not do this. Just download the bold version of the typeface! Faked bolds should be eliminated. –  Alan Shutko Aug 1 '14 at 18:18
I used the download zip at ibarrareal.es , Better with you link –  Zhen Aug 1 '14 at 18:36

I don't have that font, so I used (actually abused) EB Garamond, but it should work the same with your font.

\documentclass{article}
\usepackage{fontspec}
\setmainfont[
Ligatures=TeX,
Extension=.otf,
BoldFont=EBGaramond12-Regular,
BoldFeatures={FakeBold=3},
ItalicFont=EBGaramond12-Italic,
BoldItalicFont=EBGaramond12-Italic,
BoldItalicFeatures={FakeBold=3},
]{EBGaramond12-Regular}
