This is my first question here, I did search but uhmm haven't found the answer. I have a document that must follow the next rules: The chapter header in uppercase and bold and arial 13 pt; section header in lowercase and arial 13 pt; subsection header in lowercase and slanted font and arial 13 pt; and finally the main font for the document is arial 12 pt.
Following enter link description here Along with the scrbook guide (p. 55) I can almost get it, except for the chapter header that I am not sure how to make at the same time bold and in small caps.
\documentclass[12pt,spanish]{scrbook}
\usepackage[spanish]{babel}
\usepackage[scaled]{uarial}
\renewcommand{\familydefault}{\sfdefault}
\usepackage{kpfonts}
\setkomafont{chapter}{\normalfont\increase\rmfamily\scshape}
\setkomafont{section}{\normalfont\increase}
\setkomafont{subsection}{\normalfont\increase\rmfamily\slshape}
\begin{document}
\chapter{Un título bastante largo para probar}
Algo de texto ¿Por qué no?
\section{Un título bastante largo para probar}
Algo de texto ¿Por qué no?
\subsection{Un título un poquitillo más largo}
Algo de texto ¿Por qué no?, así es.
\end{document}
Any help is extremely appreciated.
