The process of screen printing is quite similar to that of letterpress or lithography. The only difference is that the process uses a transparent overlay instead of a t-shirt or another flat surface. The original image is drawn or photocopied directly onto the overlay, which will be used to create the graphic. The area to be inked must not be transparent, and the film or image used as a stencil can be anything that blocks ultraviolet light. The black-and-white positive is also projected onto the screen. A film positive is usually exposed.
The emulsion is then spread over the surface of the screen. Then, the screen is exposed to light. Then, the negative part of the screen is blocked off to make a stencil, which will create a shape or outline of the design on the substrate. Once the emulsion is dry, the stencil is placed over the dry screen, which must be exposed to a strong light source to print the design. Afterwards, the printed image is transferred to the substrate.
Once the design is complete, the next step is to place it on the screen. A production worker will spread a thick, green emulsion over the screen, which will act as a stencil to guide the ink through the screen. The ink will be transferred through the stencil’s open spaces, only the UV sensitive parts of the design will remain visible on the substrate. Once the screen is ready for printing, the process can be repeated a number of times, if necessary.
There are various types of screen printing. Large print works use large tubs of special cleaning fluid, acid, or a special cloth to remove traces of the emulsion. Smaller print works use a sink or a water trough. Some even use a power hose to clean the screens. There are many advantages to screen printing, including its legality and ease of use. There is no need to worry about the safety of your screens when printing.
There are various types of screens available for screen printing. The most common is the ironing method, which is the most popular among beginners. The iron is used to set the ink after it has been applied to the screen. Iron can be used as a home iron, or a heat press is also available in some shops. However, it is best to use a heat gun or dryer to avoid damage to the screen. One should always use a good quality ink when doing screen printing.
When using screens for screen printing, choose cotton for its durability and flexibility. The best fabric for screen printing is cotton. If possible, go for organic cotton and 100% cotton. It is more durable and affordable than other materials, and has a longer life span. It is often used for t-shirt production. Moreover, many people find it appealing to wear t-shirts, which are ideal for a wide range of occasions. It is an excellent way to make a living from screen-printed designs.
