I couldn't find a specific term for 'schärfen' in this context at all.
However, I came across a link that you might find useful where the whole process is described in lots of lovely detail.
It's an extract from the book:
Application of Dyestuffs To Textiles, Paper, Leather and Other Materials
by J. Merritt Matthews, Ph.D. 1920, Chapter 18 (The Vat Dyes)
1. Classes of Vat Dyes
2. Indigo
3. Methods of Dyeing Indigo
hope it helps
