Here is a well-known Digambar Pratikraman book you can look for:

• Digambar Pratikraman by Subhash — a detailed text used in many Digambar communities for the Pratikraman ritual (includes Brhatsāmāyika passages and the core alochana with Kayotsarga, Pachchakkhan, etc.).

If you’d like, you can also read about the Digambar Pratikraman procedure and sutras in Jain Knowledge articles that outline the Digambara vidhi and key prayers. You can read more here ( jainknowledge.com)

Note: Pratikraman practices can vary slightly between Digambar and Shvetambar traditions, but the core purpose—confession, forgiveness, and renewal of vows—remains the same.
