Appropriate surface treatments and finishes that can be applied for functional and aesthetic purposes [Papers & boards]
This topic covers the application of surface treatments and finishes to papers and boards for both functional and aesthetic purposes, including commercial printing and finishing processes.
Topic Overview
Surface treatments and finishes for papers and boards are essential in Design and Technology to enhance both the functionality and aesthetics of a product. This topic covers a range of techniques from simple coatings like varnishes to more complex laminations and embossing. Understanding these finishes allows you to protect the material from moisture, wear, and tear, while also improving its visual appeal, texture, and even tactile qualities. In the WJEC GCSE, you'll need to justify your choice of finish based on the product's intended use, target market, and production methods.
Finishes can be applied for functional reasons, such as making a paper or board waterproof, grease-resistant, or more durable. Aesthetic finishes include gloss or matte coatings, metallic foils, and textured surfaces that can make a product stand out. The choice of finish also impacts sustainability—some finishes can make recycling difficult, so you need to consider environmental implications. This topic links closely to material properties, manufacturing processes, and design specification requirements.
In the wider subject, surface treatments and finishes are part of the 'Materials and their properties' section, but they also appear in 'Designing and making principles'. You'll be expected to select appropriate finishes for given contexts, explain their benefits and drawbacks, and evaluate their suitability. Mastery of this topic will help you in both the written exam and the NEA (Non-Exam Assessment) where you must justify your material and finish choices.
Key Concepts
Core ideas you must understand for this topic
- →Functional finishes: varnishes (gloss/matte), UV coating, laminating, waxing, and waterproof coatings protect against moisture, dirt, and wear.
- →Aesthetic finishes: embossing, debossing, foil blocking, spot UV, and textured finishes (e.g., linen or felt finishes) enhance visual and tactile appeal.
- →Printing finishes: aqueous coating, UV varnish, and lamination can be applied over printed areas to protect ink and add sheen.
- →Sustainability: some finishes (e.g., plastic lamination) make recycling difficult; water-based or biodegradable finishes are more eco-friendly.
- →Application methods: finishes can be applied by spraying, roller coating, screen printing, or using heat and pressure (e.g., foiling).

Examiner Tips
Expert advice for maximising your marks
- 💡Always link the finish to the product's function and user needs. For example, a children's book might need a wipe-clean laminated finish for durability, while a luxury chocolate box might use foil blocking for a premium feel.
- 💡In exam questions, use specific terminology like 'UV varnish', 'aqueous coating', or 'spot UV' to show detailed knowledge. Avoid vague terms like 'coating' without specifying the type.
- 💡Consider the environmental impact: finishes that hinder recycling (e.g., plastic lamination) may lose marks if sustainability is a key requirement. Mentioning eco-friendly alternatives like water-based varnishes can boost your answer.
Common Mistakes
Pitfalls to avoid in your exam answers
- Misconception: All varnishes are the same. Correction: Gloss varnish reflects light and gives a shiny finish, while matte varnish reduces glare and gives a smooth, non-reflective surface. UV varnish is cured with ultraviolet light and is more durable.
- Misconception: Lamination always makes paper recyclable. Correction: Plastic lamination (e.g., polypropylene) is not easily recyclable and can contaminate paper recycling. Biodegradable laminates exist but are less common.
- Misconception: Embossing and debossing are the same. Correction: Embossing raises the surface (creates a raised pattern), while debossing depresses it (creates an indentation). Both are used for tactile effects.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Day 1-2: Learn the key functional finishes (varnishes, laminates, wax) and their properties. Create flashcards for each finish with its purpose, application method, and pros/cons.
- 2Day 3-4: Study aesthetic finishes (embossing, foiling, spot UV). Look at real product examples (e.g., business cards, packaging) to see how they're used.
- 3Day 5-6: Focus on sustainability. Research which finishes are recyclable and which are not. Practice explaining trade-offs between performance and eco-friendliness.
- 4Day 7-8: Work through past exam questions on finishes. Identify command words (e.g., 'Explain', 'Evaluate') and practice structuring answers.
- 5Day 9-10: Revise by teaching someone else or using active recall. Test yourself on matching finishes to products (e.g., 'Which finish for a takeaway coffee cup?').
Exam Question Types
How this topic typically appears in the exam
- 📋Multiple choice: Identifying the correct finish for a given scenario (e.g., 'Which finish would make a paper bag waterproof?'). Tip: Eliminate obviously wrong options first.
- 📋Short answer: 'Explain two functional reasons for applying a varnish to a board game.' Tip: Use specific terms like 'protect from moisture' and 'reduce wear on printed areas'.
- 📋Extended response: 'Evaluate the use of plastic lamination versus UV varnish for a set of recipe cards.' Tip: Discuss durability, cost, aesthetics, and recyclability. Conclude with a justified recommendation.
- 📋Design question: 'Suggest a suitable finish for a children's pop-up book and justify your choice.' Tip: Consider safety (non-toxic), durability, and tactile appeal.
Command Word Expectations (WJEC)
What examiners look for when using specific command words in this specification
Give a detailed account of reasons or causes. For finishes, state the purpose (e.g., 'to protect from moisture') and how it works (e.g., 'by creating a barrier that prevents water absorption'). Must include specific finish names and properties.
Weigh up the pros and cons of different finishes, considering factors like cost, durability, aesthetics, and environmental impact. Reach a justified conclusion. Use comparative language (e.g., 'more durable but less eco-friendly').
Provide reasons for a choice based on the design specification. For example, 'I chose gloss lamination because it is wipe-clean and enhances colour vibrancy, which is important for a children's book that will be handled frequently.'
