Paper & Board: Quality Control
Quality Control
Quality Control
Quality control allows the quality of items produced to be kept to a high standard. This is incredibly important as each paper-based product needs to be the same size and of the same quality.


Tolerance
Tolerance
- This is the allowance allowed for products in terms of their accuracy of measurements and accuracy of build to allow for computer or human error.
- This does not mean the product will be of low quality but there will be a threshold that each product needs to meet.
- Products need to strive to be perfect but account for humans and machines sometimes making small inaccuracies.


Example: A4 paper
Example: A4 paper
- For example, the measurements of an A4 paper are 22.1cm x 29.7 cm and if any of the papers measurements was was out by 0.5mm +/- then it would result in an inaccurate product.
- From this, the measurement for the width is allowed to range between 22.05 cm and 22.15cm in order for it to be acceptable.


Colour registration marks
Colour registration marks
- Registration marks are used for prints and fabric prints.
- The registration mark will be produced at the bottom of the finished piece.
- If the registration mark is misaligned then it will not show the colours fitting in each sector perfectly.
- The reason why this may happen is because of the misalignment of each or some colour plates.


Visual inspections
Visual inspections
- The most common type of inspection used in most stages are the visual inspection, without this, there can be spelling errors or presentational errors such as wrong colours or graphics.


Testing of early drafts and prototypes
Testing of early drafts and prototypes
- To ensure there are fewer issues, prototyping and draft prints stop or limit the number of errors for the final print.
- Drafts are usually printed on paper that is thinner or cheaper.
- The reason for this is to ensure that the product is perfect before it goes forward for production.
- This can save time and money but most importantly can ensure accuracy.
