Colour variations means there may be slight changes in colour from what you have seen on screen, to the printed copy. This is the nature of the print industry.
If you print a proof on your own printer, keep in mind that depending upon the manufacturer of printing equipment, colours may vary slightly due to different ink used. We cannot be held responsible for colour variations, as it is beyond our control and we will not reprint at our expense as a result of such variations.
There can be a colour variation from run to run also, this may result in slight alterations in the colouring for repeat orders. The best way to maintain consistency is to request a printed colour proof. From the proof we can make alterations until you are happy with the colours.
