3. Strength
4. Brightness
5. Thickness
You can change the properties of paper in 3 ways
1) Coatings
- Give a smooth finish
- e.g. china clay
2) Sizing Agent
- Improves paper's ink absorbency
- This also affects brightness
3) Laminating
- Different types of boards can be made from this
Paper thickness is measured in GSM ­ grams per square metre
220+ gsm = board
Board thickness is measured in microns
There are 1000 microns in 1 mm
