The invention provides a method of applying a design by a printing process to an expanse of material [18] which is dimensionally unstable, in particular genuine tanned leather and synthetic leather, which method includes the steps of adhesively applying the material to a rigid backing plate [20] to define a pictorial area [18.1] where the material adheres to the backing plate [20]; providing adjustable key means [22, 24] on a print table [10] of a stencil or screen printing apparatus, to demarcate a selected position for the backing plate [20] where a print plate [12.1, 12.2, 12.3, 12.4] of the printing apparatus will produce a printed image [36, 42] in a desired location on the pictorial area [18.1]; positioning the backing plate [20] in the demarcated position with reference to the key means [22, 24]; and printing a printed image [36, 42] in the desired locality on the pictorial area. The key means is preferably a displaceable base plate [22] which can be placed in a desired position on the print table [10]. The base plate [22] has keying pins [24] to engage with keying apertures [26] in a backing plate [20]. To achieve an accurate placement of successive images [36, 42] where a multi-colour design is to be printed, a transparent overlay sheet [30] is provided over the pictorial area [18.1], and a trial image [34, 40] is printed on the overlay sheet [30], whereupon the position of the base plate [20] is adjusted with reference to the trial image. <IMAGE> |
