Lessons
i.Beginner
Beginner lessons establish what PNG is, what information it contains, and how to prepare a simple file without confusing pixels, transparency, or resolution metadata with production instructions.
Beginner lesson sequence
- 1
PNG fundamentals
Identify PNG as a losslessly compressed raster image and compare it with vector, document, and machine formats.
- 2
Pixels and size
Read pixel dimensions and calculate effective resolution at a specified physical size.
- 3
Transparency
Distinguish transparent pixels from white pixels and inspect artwork on contrasting backgrounds.
- 4
Basic export
Export a correctly sized PNG from an editable source and reopen the result.
- 5
Production fit
Identify whether a selected raster production method can use the PNG directly.
Completion evidence: one validated PNG, its editable source, and a short note stating the intended product, method, final size, and transparency choice.
ii.Intermediate
Intermediate lessons connect PNG artwork to product templates, color-managed handoff, production software, companion files, and repeatable maker intake.
Intermediate lesson sequence
- 1
Product-based setup
Use printable area, bleed, safe area, seams, curves, and restricted zones correctly.
- 2
Color and alpha
Inspect profiles, transparency edges, partial alpha, substrate color, and proof requirements.
- 3
Companion files
Determine when a cut contour, editable source, placement proof, or machine-specific file is required.
- 4
Maker preflight
Validate file, order, material, machine, preset, and product as one production package.
- 5
Controlled proof
Produce or evaluate a test that isolates scale, placement, color, or edge behavior.
Completion evidence: a product-ready PNG package with template, production notes, companion file when applicable, and a completed intake checklist.
iii.Advanced
Advanced lessons focus on technical PNG structure, workflow validation, controlled production, repeatability, and root-cause analysis across several production systems.
Advanced lesson sequence
- 1
Datastream structure
Interpret color type, bit depth, alpha representation, critical chunks, ancillary chunks, filtering, compression, and interlacing.
- 2
Workflow comparison
Explain how the same PNG is interpreted differently by sublimation, DTF, DTG, raster engraving, and print-and-cut systems.
- 3
Process control
Document controlled inputs, approved settings, tolerances, inspection rules, and change control.
- 4
Failure isolation
Separate file, software, machine, material, process, and quality-control causes using controlled tests.
- 5
Repeatability review
Demonstrate that an approved result can be reproduced or explain which variables prevent it.
Completion evidence: a documented production case showing technical validation, proof strategy, production record, inspection result, and corrective action for at least one controlled failure.
