As screen printers, it is easy to forget the flexibility of the process in terms of the range of materials than can be printed onto an equally large number of substrates. The term "Ink" covers anything that can be suspended in a fluid and made to flow through a screen mesh. To do this it must be possible to dissolve the material or turn it into a powder that can be held in suspension within a fluid. I could bore or amuse you with a list of materials that can be printed through a mesh. From Antibiotics to Zirconium through to more unexpected materials including cement, butter, glass and deodorant, all will flow through the mesh with encouragement from the squeegee. So how is this characteristic of the process going to improve your profitability? It could open new markets, or enable you to offer additional products to existing customers. Never assume your client understands the capabilities of the screen printing process. Let us look first at the readily available specialist ink systems.
