When you supply a sample panel for colour matching if you require this to be kept on file we would formulate this. As we match by eye, our mixers would keep a record of every tinter and base which has been added to the mix and keep this on record under a special formulation code which you will use for all future orders. This formulation code would have to be provided every time you require this colour.
If you supply a sample panel and do not require this to be formulated it will be sent back with the goods.
