Yes. In some cases, there is an additional charge for this service in order to buy the correct ink if an exact match is required. There are a few products in which this is not possible due to the limitations of the imprinting process.
Your Customer Care Representative will help you with this. Just let AnyPromo.com know which colors they should be working towards in the additional comments section in the order process, or just let your representative know (you will get an email from them shortly after you place your order).
