It is difficult to show accurate colours or the quality and finish and weight of our paper and card on a screen. If you are unsure of its suitability for your purposes we suggest you place a small order to try.
Cards are suitable for home printing, please always check your individual printer specifications prior to attempting to print, as we cannot guarantee all printers will accommodate thicker paper/card.
