PNG

Skill mastery means the learner can prepare and validate a production-ready PNG without step-by-step prompting and can explain the reasoning behind each major decision.

This achievement should be awarded only after the evidence and assessment requirements in section 17 are met. It is proposed and is not currently automated.

Guide mastery combines complete coverage of the PNG guide with passed knowledge, application, and troubleshooting evidence. It is stronger than guide completion because it verifies transfer of learning.

PNG mastery does not automatically grant mastery of sublimation, DTF, DTG, laser engraving, print-and-cut, or another production method. Each method requires separate equipment, material, safety, setup, finishing, and quality competence.

A production-method mastery achievement should come from that method's curriculum and practical assessment, with PNG preparation counted only as one supporting skill where applicable.

File-type mastery is the highest PNG-specific achievement proposed for this guide. It indicates that the learner understands the format, creates production-suitable files, applies them correctly, troubleshoots failures, and meets consistent quality requirements.

This achievement remains proposed until Gudiee implements the assessment, review, award, revocation, and versioning workflow.
