Performance characteristics of materials Performance characteristics of papers and boards explained
Cutting is the process of separating paper or board along a line using a blade, guillotine or die.
Read the full explanation
The performance characteristic is how well a given paper or board can be cut: whether it gives a clean, straight edge without tearing, crushing, delaminating or fraying. Thin paper cuts easily with a craft knife or guillotine but can tear if the blade is blunt. Thick or dense board needs a sharper blade, more pressure or a die-cutting process, and may crush or feather at the edge if cut poorly. In practice a straight edge guides a craft knife for short runs, a guillotine gives repeatable straight cuts, and die cutting suits complex or volume shapes. Assessors judge cutting quality by inspecting the cut edge for straightness, cleanliness and damage to the surface.
Your focus
- Describe how paper and board are cut using a knife, guillotine or die.
- Explain how the ability to be cut depends on material thickness, density and blade condition.
- Outline how to judge whether a cut edge is clean and accurate.

Marking Points
- Defines cutting as separating paper or board along a line with a blade, guillotine or die.
- Explains that the ability to be cut is how cleanly a material separates without tearing, crushing, delaminating or fraying.
- Links material thickness and density to the blade sharpness, pressure or process needed.
- Compares hand cutting with a guided knife, guillotine cutting and die cutting for different shapes and volumes.
- Describes judging a cut by inspecting the edge for straightness, cleanliness and surface damage.
Examiner Tips
- 💡Name the tool or process and the material it suits.
- 💡Describe what a good cut edge looks like and what defects to check for.
- 💡Compare methods by shape complexity and quantity, not just by preference.
- 💡Keep the distinction between cutting and scoring clear in your answer.
Common Mistakes
- Treating cutting and scoring as the same operation; correction: cutting separates the sheet, scoring only creases it for folding.
- Assuming a blunt blade is adequate for thin paper; correction: a blunt blade tears and frays even thin stock.
- Ignoring edge quality; correction: a good cut is straight and clean with no crushing or delamination.
- Using a craft knife for every job; correction: a guillotine or die cutter gives repeatable or complex cuts where appropriate.
