The scope to print patterns and designs are endless, and there exists many materials on which this can be experimented upon. There are many organizations which get some logo or symbol printed on various clothings like caps, shirts and even magnets. The products can be of varying qualities as what is to be preferred.
It is a lively business that involves creativity and very low investment. The customers normally come up with their own plans and designs and sometimes it can be designed by you. You can buy a complete printing press and setup the whole business with a very minimal investment in the same. The most essential itineraries are a frame, masking tape, squeegee, light dye and t-shirts. A little more investment in things like a printing press screen will make things easier.
These things can be printed easily and sold at a premium, making profits on these things are very easy and quite simple. The ink is pushed through the stencil and frame setup using a pump and this ink gets absorbed on the threads of the woven mesh, the cloth. The blank spaces and the coloring together lead to the formation of the pattern or design that you desire to print. This is normally done on silk screen or something with a very fine material with an impermeable substance.
A fine woven fabric which looks like a mesh is used to stretch over and cover an aluminum frame. This mesh is normally made up of fine materials like silk but nowadays materials like steel, nylon, and polyester are also being used. There are many areas of the screen which are blocked off with some non-permeable material to form a structure like that of a stencil, which is nothing but a negative of the image to be made; that is, the open spaces are where the ink will appear to form the picture.
Prior to ink is applied to the screen, the screen and casing must go through a development referred to as 'pre-press'. In this method, a blend is 'scooped' across the lattice and the 'exposure unit' burns away the pointless emulsion leaving behind a spotless area in the lattice with the indistinguishable shape as the desired illustration. The pallet that the material will be in print against is covered with a wide 'pallet tape'. This supply to protect the 'pallet' from any surplus ink leaking through the substrate and potentially discoloration the 'pallet' or the transfer of unwanted ink onto the next substrate. Further, the screen and the constructed frame using an adhesive tape. The last process in the 'pre-press' is jamming out any superfluous 'pin-holes' in the suspension. If these holes are left in the blend, the ink will maintain through and leave unwanted marks. To obstruct these holes, materials such as adhesive tapes, specialty mixture and 'block-out pens' may be used effectively.
