block print This traditional hand printed process is especially suitable for more exclusive papers. It requires immense skill and a long apprenticeship. The effect is a heavy build up of colour providing a special depth and graining. The advantage of block printing is the availablitiy of large repeat sizes (up to 183cms / 72ins). Available in custom colours and backgrounds. Minimum order is 10 x 10m Rolls. Cole & Son holds over 1800 block designs. flocking - hand blocked & hand made Flock printing, revived by Coles owner John Perry in the 1870s, is a process that replicates cut velvet on wallpaper. The process involves hand block printing of a special glue instead of ink, and then cut wool or viscose is vigorously shaken onto the surface of the paper.
