There are three particular methods usually employed to accomplish screen printing that produces printed garments for promotions, merchandise and fashion. For any t-shirt printer, ‘Spot Colour’ printing is the most common and works exceptionally well for a great variety of graphics. Spot colour printing is best used when printing graphics which are usually not very photographic in nature.

The colours of the inks to be used in the reproduction of the graphic images are usually Pantone specified colours chosen by a graphic designer. Pantone coated or noncoated color types are selected to clarify the ink hues of the pattern. Used in publishing, printing and design, the Pantone matching system, is internationally used to identify colors with a unique name and number.

When colour identity and uniformity is an issue, for example in branded promotional garments or a large selection of products, this method of spot color printing works very well.

The Four Color Process is another method used in screen printing. Printing in this style is primarily used for images and illustrations that use a wide range of colours, shades and tones. The method used to print images found in magazines and books is the 4 colour process as well.

Reproducing the colours of the original image requires a mixing of translucent inks on a white background. This is of course a rather more difficult process to achieve on a fabric than it is on paper. But the method used is about the same. The printing that you choose will work only on white articles of clothing and will not show correctly on coloured items. The print set up costs are higher than that of simple spot colour designs and as such only suitable for larger print runs of 100+.

When garment screen printers reproduce such full colour images onto coloured fabrics a method called ‘Simulated Process’ is used. The artwork is separated into various colours and shades using a method similar to spot colour, as used by a t-shirt printer, to achieve the overall look and feel of the original image.

This is a standard method used by all printers and most popular for example with the reproduction of heavy metal and fantasy imagery taken from CD cover artwork and reproduced onto black t-shirts for band merchandise. This, for a t-shirt printer is the most expensive. For that reason, it is used entirely on large print runs. This is because it costs more to set up the colour separations, and it takes a greater number of colours to print the pictures.
