Especificaciones y seguridad
Directrices de seguridad para la arquitectura y la impresión
Los archivos de salida de Librava se someten a cálculos geométricos determinísticos basados en el número total de páginas para calcular con exactitud el margen interior, el recorte exterior y los márgenes de sangrado que exigen las editoriales comerciales.
Esto elimina por completo los rechazos por problemas de alineación y las distorsiones de escala durante la encuadernación física, lo que la convierte en la plataforma perfecta para los autores independientes que desean expandirse.
