Promotional photo mugs or the more technical term  Dye sublimation mugs offer you a visually amazing way to promote your business or organisation.. The technique uses popular organic colour dyes which achieve vibrant colours and crystal clear printing results. What's more, this printing method is also environmentally friendly. The dye does not contain substances such as lead and cadmium. The absence of these harmful chemicals does not affect the print in a negative way. In fact, you can expect a finished product that has a beautiful glossy appearance. If you have a full colour logo or picture to print, promotional photo mugs are an excellent product that simply must be seen.
