Screen Printing for Custom Printed Tshirts
When many people hear, the word what “screen printing” or “silk printing” they automatically think of the printing on a t-shirt but screen printing can involve being used on substrates ranging from metal to plastic. Screen printing is best suited for video, bold designs. A printing technique is specially suited for an appartment or relative flat work surface. The process involves a screen or fine nylon uppers expanded securely around a frame that is form. If there printed Tshirts are areas you don’t want printed, they are masked on the printing screen. To create the print the framed screen will be positioned over the item you want printed with a blob of thick paint. To press the printer through the screen you would use a squeegee. A stiff plastic blade is attached with a plastic or wooden handle. It is used to pull the pain across the screen to press the printer through the screen.
In the areas that are masked the printer is avoided from passing through but the areas that are unmasked will allow the web link to be produced. Once this is done, the item is put on a conveyor belt through the heat canal. This is called a curing process to ensure that the inks will dry quickly that the material can be packaged or stacked. If the inks have been properly cured, they will remain, even under harsh conditions, on the printed substrate. If there are more colors desired in the final design then the process will be repeated with the different screens. For example, if the design requires three colors then it would require three different screens.
To make sure that the colors are registered or properly arranged with each other, the screens are placed on a rotary press. Some screen printers have fully automatic pressers. With one of these types, they don’t require any manual labor other than setting up the machines and then packing and unloading the machines.
A screen can be masked in many various ways. Applying hiding fluid directly onto the screen is the most straightforward way. This way is for simple one or two graphics images. For printing that is more complicated it is ineffective. Screen printers will often use photosensitive emulsions for multicolor jobs. The first step is for the design to create on a clear part of plastic file. Next, a photosensitive coating is applied to the entire screen surface. Once it has dried, the film will be placed on the screen and then it will be come across bright light. After a period of time, the screen printer will wash the exposed areas off the screen with water. Now the screen is just about to print. If you are printing on a dark color, a white base coat will be applied first.
