Screen Printed Sweatshirts-A Part Of Modern Lifestyle

A sweater, pullover, jumper, or jersey is a relatively heavy garment intended to cover the torso and arms of the human body (though, in some cases, sweaters are made for dogs and occasionally other animals) and usually worn over a shirt, blouse, T-shirt or other top. Sweaters tend to be, and in earlier times always were, made from wool (typically of sheep, though possibly of alpaca or other type); however, they can be made of cotton, synthetic fibers, or some combination thereof. Sweaters are maintained by washing, and the use of a lint roller. A sweatshirt is not something that we wear to office but as a casual wear in your free time the new-generation sweatshirts that give a cozy feeling and a perfect fit looks very pleasing. Sweatshirts are, in fact, gaining prominence as a very popular type of clothing preferred by millions of people across the globe, which comes in a wide range of colors, sizes and with many different images screen printed on the front and back of the shirt.

Screen printing or silk screening is a printing technique which suits flat surfaces. The core of the process constitutes a fine mesh or screen which is tightly stretched around a solid frame. The areas that need not be printed are masked off on the screen. The print is created by positioning the framed screen over the item to be printed along with a small quantity of thick ink. A metal blade is then used to press the ink through the screen. The unmasked areas allow the ink to be imprinted on the material while the masked areas prevent ink from passing through. The last stage of the process is sending the item on a conveyor belt which passes through a heat tunnel. This process is to make sure that the ink dries off fast so as to allow the materials to be packed or stored.

The process is repeated if there is a need for more colors. This means that the process should be repeated for each and every color. The screens are placed on a revolving press which allows different color prints to be properly aligned or merged with each other. These days automatic screen printers are available in the market, which does not require any manual labor, except for the setting up and the loading and unloading work. There are multiple options to mask a screen. The most popular among them is to apply the masking liquid directly on to the screen. This method is suited when only one or two colors are needed. For more colors to be printed, the best alternative is to use photosensitive emulsion.
There are three types of screen printing presses. The 'flat-bed' (probably the most widely used), 'cylinder', and 'rotary'. Textile items are printed in multi-color designs using a wet on wet technique, while graphic items are allowed to dry between colors that are then printed with another screen and often in a different color.

Over the years, people have been using silk screening to place designs on t-shirts, until recently, when modern technology has been adopted such as digital printing using inkjet printers. Silk screening, however, has always remained an attractive source of high quality prints on shirts.
