Screen printing is one of the oldest techniques of printing apparel where a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil. Screen Printing is commonly used and the most cost efficient way of printing on most apparel items. It is also known as silk-screen, screen, serigraphy, and serigraph printing. One color is printed at a time, so several screens can be used to produce a multicolored image or design. This process is not an easy task and it requires many steps to complete a custom design. The Screen printing process begins with the design. Once we get a design from a client or create a design that is approved by a client, we will then determine the type of screen printing you need.

Embroidery is the technique of decorating fabric or other materials with a needle and thread. Embroidery may also incorporate other materials such as, pearls, beads, quills, and sequins. Earlier historic examples of embroidery include chain stitch, blanket stitch, satin stitch, and cross stitch which remain the remain the fundamental techniques of hand embroidery. Embroidery today is in a wide variety of tread colors and is seen on caps, hats, coats, blankets, dress shirts, denim, stockings, and golf shirts. Embroidery years ago was considered very expensive due to the time consuming methods used to carry out this process. In recent years, embroidery has become more affordable due to the process of digitizing and automation. The modern cost effective ways of embroidery translates to savings for the consumer making it a more affordable option.

The development process begins with a graphic design that is converted into a digital format that the embroidery machine can recognize. These set of operations are known as digitizing which is a very time consuming part of the whole process. Once the file is digitized, it goes into the embroidery program on the computer that controls the embroidery machine. Once the embroidery machine and materials are set up, the computer sends the instructions to the embroidery machine and the design is sewn onto the product.

Direct to garment printing, also known as DTG printing, is a process of printing digital images from a computer onto a shirt or other garment through the use of an inkjet printer. This process specializes in modified inkjet technology that has a transport mechanism for the garment and specialty inks that are applied to the garment directly and are absorbed by the fibers. Direct to garment printing is similar to a home inkjet printer that is connected to your computer, except that the paper is replaced with a shirt. Like a home inkjet printer, DTG printers do not need to be set up for individual jobs and can render millions of colors.
