Hello AlexKidd, I didn't use your translation (but thanks for the idea
an italian point of view could be useful)
About the "embolden level" ("Glyph embolden" is the menu option) is for PDFs and what the device actually does is making things darker, not only makes the letters bold (darker and thicker) but also darkens everything except the white background. I know it's not exactly a "contrast level" but I didn't think of anything better in spanish (impossible to translate embolden). Anyway thanks for the comments
