We ordered A4 wall calendar for a charity project and they are really good. Colours are perfect the and paper quality is great. I found the program for designing the calendar not quite as user friendly as I would have liked but I persevered and am extremely happy with the finished product so much so that we designed a desk calendar and ordered 100 of those too!
I've used Colour Digital Print twice now and both times the service was first class and the quality of the product was excellent. I wouldn't hesitate to use them again for all my future printing projects
