Today, screen printing uses manmade threads of steel, nylon, and polyester - no silk at all. Screen printing is a stencil method of print making in which a design is imposed on a screen of silk or other fine mesh, with blank areas coated with an impermeable substance, and ink is forced through the mesh onto the printing surface.
The few of the practical mediums for selling your screen printing services are:-
Long letter formats in direct mail and the internet: Because you need the space to ask and answer questions about what the customer needs and what the customer should have. And you also need the space to show massive amounts of testimonials to prove you are the best choice to screen printing.
Word of mouth: The easy way to use word of mouth marketing is to create a campaign for your database of customers, asking for referrals. To make it even more effective, add a gift to motivate your past customers to refer your services. This is where promotional items come in handy. It does not have to be expensive, just nice to have.
