Quality Control

These are a series of checks a product must undergo to ensure it is of a marketable quality. This ensures it meets specific standards. Checks are conducted on the size, weight, color and construction of the product among other things. 

Testing needs to be undergone at every stage of development. This ensures that say a bottle top is being created in the production line with the correct thickness diameter etc

Quality Controls 

• color bar - check density and consistency of printed colors
• registration mark - ensure printing plates are aligned
• crop mark - make sure the product is cut to the correct size
• visual checks - make sure their is no breaks in the type face and all text is clear and legible

all these controls must be applied to every page
