To validate a tech pack, ask for a sample from your supplier. If the sample made is the same as mentioned in the tech pack, it means the supplier has understood your requirements.
Errors in reading the tech pack are possible because the supplier is either relatively new or the factory, may be located out of the country or there is a language gap. It can also be possible that the factory has not dealt with textile products before. To avoid any such discrepancies, changes can be made in the tech pack at any time of production.
