I'm currently working on a technical book with lots of inline and display equations that are written in Cambria Math. As per notation rules, variables need to be italicized but Cambria Math does not have an italic style. I have read that one can skew the letter to fake this effect (specially when they are single letters, not entire words), but I fear it may cause trouble when printing the file with an offset printer (my digital printer doesn't even print the skew, the variables print as roman letters). The same goes to using bold with variables that are vectors, applying a little weight to the letters.
Can I skew the letters in this way, or do I need to switch fonts in order to get a true italic style? In this case, is there any recommendation you could give me?
Cambria Math doesn't have italics, but Cambria does have an italics version, which includes Latin and Greek letters and much more.
So, for variables (whether Latin or Greek letters) use Cambria Italics, and for the symbols you need, use Cambria Math.
Thank you very much, I didn't realize Cambria has an italic version. I'm changing all my variables to that, and I'll keep the symbols as Cambria Math.
