The step of printing onto the surface of a flexible sheet material conventionally involves printing a colour image by a plurality of offset litho printing steps, then screen over printing a dense white continuous layer on what becomes the back of the image. The plastics sheet is conventionally adhered to the base layer by means of a more or less white self adhesive tape. When we investigated the possibility of leaving out the white screen printing step, we found that tiny air bubbles spoiled the image as seen through the plastics sheet. Against this background, there is disclosed a method of making a mouse mat, comprising the steps of: printing a design and/or text onto a surface of a flexible sheet plastics material; printing by offset litho white ink over the said design and/or text; and adhering the printed surface onto a resiliently compressible backing sheet using a double sided self adhesive tape having a white liner. Offset litho printing has the advantages of being quicker and less labour intensive. It is possible to use inks which are cured by exposure to ultraviolet light, so avoiding the drying and stacking problems. Much less ink is used. |
