The important thing about contrasts is to maintain the right balance.
There are essentially 3 methods to create contrasts:
1) cross-hatching/fine details
2) half tones
3) black fills
All of them have their pros and cons (and proper uses).
However, if you rely too much on only one technique chances are that your pages will look lackluster...
Therefore it‘s a good idea to combine these methods.
No method or combination is the best. Use all tools available at your disposal!
