Introduction to Material Selection: Papers and Boards
Welcome! When you design a product, choosing the right material is one of the most important decisions you will make. Imagine trying to print a high-quality wedding invitation on a piece of rough, brown corrugated cardboard—it just wouldn't work! In this chapter, we will look at why designers choose specific papers and boards. We call these Influencing Factors. By the end of these notes, you’ll understand how aesthetics, the environment, cost, and social issues help designers pick the perfect material for the job.1. Aesthetic Factors: The "Look and Feel"
Aesthetics is all about how a product looks and feels to the user. This is crucial because it is often the first thing a customer notices.Form
Form refers to the shape and structure of the material. Some boards, like folding boxboard, are chosen because they are easy to score and fold into complex 3D shapes. Others, like solid white board, are chosen because they stay flat and rigid for high-end book covers.Colour
The colour of paper or board affects how it is perceived.- Solid white board is often chosen for medicines or luxury items because white looks clean and "pure."
- Brown corrugated board is used for shipping boxes because its natural colour suggests it is recycled and functional.
Texture
Texture is how the material feels.- Cartridge paper has a slightly rough texture (a "tooth") which helps pencil lead or charcoal grip the surface.
- Foil-lined board feels smooth and metallic, which can make a product feel more expensive or "high-tech."
Quick Tip: If a question asks about aesthetics, think about the "Three Senses": How does it look, how does it feel, and what does the shape tell you?
2. Environmental and Ecological Factors
Designers today must think about the planet. Every piece of paper starts as a tree, and how we handle that process matters.Sustainability and Extraction
Sustainability means meeting our needs today without stopping future generations from meeting theirs.- Extraction: Most papers come from wood pulp. If we cut down forests without replanting them, it’s not sustainable.
- Processing: Turning wood into paper uses a lot of water and energy. Using chemicals to bleach paper white can cause pollution.
Ecological Footprint
This is the impact of a product on the environment.- Transportation: If paper is made in one country and shipped to another, it has a high carbon footprint.
- Wastage: Designers try to "nest" their shapes (fitting them closely together) to reduce the amount of scrap material.
- Biodegradability: One of the best things about papers and boards is that they are biodegradable—they break down naturally over time.
Did you know? Using recycled paper uses roughly \(40\%\) less energy than making paper from fresh wood pulp!
3. Social and Ethical Factors
Social factors are about how people and society are affected by the products we make.Social Footprint
This includes trend forecasting—designers look at what is popular to decide which materials to use. For example, if "eco-friendly" living is a trend, a designer might choose unbleached, recycled board to appeal to customers.Ethical Factors and the Consumer Society
Ethics is about doing the right thing.- Avoiding Offence: Designers must ensure that the images or text printed on papers and boards do not offend different cultural or religious groups.
- Built-in Obsolescence: This is when a product is designed to be thrown away quickly so the consumer buys a new one. While common in packaging, many people now see this as unethical because it creates too much waste.
- Fair Trade: Is the person making the paper being paid a fair wage? This is a major ethical concern for modern designers.
4. Availability and Cost
At the end of the day, a business needs to make a profit.Cost
The cost of material is influenced by its quality and how it’s made.- Copier paper is very cheap because it is produced in massive quantities (mass production).
- Packaging laminates (like Tetra Pak) are more expensive because they use multiple layers, including polyethylene and aluminium foil.
Availability
If a material is hard to find, the price goes up. Designers usually choose stock forms (standard sizes like A4 or A3) because they are always available and cheaper than ordering a custom size.Key Takeaway: Designers must find a balance. A material might be beautiful (aesthetic), but if it’s too expensive or ruins the environment, it might not be the right choice!
5. Summary Table for Quick Revision
Use this table to help you discriminate (choose) between materials in your exam:
| Factor | What to consider | Example | | :--- | :--- | :--- | | Aesthetic | Form, Colour, Texture | Using foil-lined board for a luxury "shiny" look. | | Environmental | Sustainability, Recycling | Choosing biodegradable card instead of plastic. | | Social | Trends, Ethics | Avoiding built-in obsolescence to reduce waste. | | Cost | Budget, Mass Production | Using corrugated board because it is cheap for bulk shipping. |Common Mistakes to Avoid
- Mixing up "Physical" and "Aesthetic": Physical properties are things the material does (like being flexible), whereas aesthetics are how it looks.
- Forgetting the "Life Cycle": Don't just think about the material when it's new. Think about the ease of recycling and disposal too!
- Ignoring the "Consumer": Always remember who you are designing for. A child’s toy box needs different aesthetics and social considerations than a high-end smartphone box.
Final encouraging thought: Don't worry if there seem to be a lot of factors to remember. Just ask yourself: "Is it pretty? Is it kind to the planet? Is it affordable? Is it fair to people?" If you can answer those, you're halfway there!
