We use three types of methods for T-Shirt printing:


In addition to printing T-Shirts, we also offer T-Shirts at affordable prices. For more information on our variety and our printing methods, please read on.

Our printing is not limited to T-shirts and golf shirts, we also print on all kinds of materials. We have a catalogue of standard promotional shirts, as well as corporate shirts available. If you require a quote on any of our shirts, simply supply us with the unique product code in our catalogue together with the colour you require and the units per size and we will forward a quotation to you. Send your quotation request to our email HERE.

The first step in printing T-shirts, is choosing the colour and quality of the T-shirts you want to use.

It is a common mistake to assume that the thickness or weight of a T-shirt dictates its quality. The weight of T-shirt material is measured according to the grams per m2 of the material. This is usually between 135 grams and 200 grams. As an example, a 145-gram T-shirt is not necessarily of a better quality than a 170-gram T-shirt. A T-shirt that is categorised as a 145-gram, pre-shrunk, 100% cotton with interlock weaving will appear neater and hold its shape for longer than a 180g carded cotton T-shirt.

Carded cotton is usually made from a lower grade material and is mass produced. The colouring process in the production of these T-shirts is of a lower quality and has the tendency to fade after prolonged wash-and-wear. Even so, these lower grade shirts remain popular because of the competitive market and client budget constraints.

Coming and carding are two ways of preparing the raw fibres for spinning yarn. In order to make yarn, raw fibre must go through an alignment process. Here are some of the differences between carded and combed yarn:

  • Carding the fibres creates a somewhat woollier yarn because the alignment process is not as meticulous.
  • Combing creates an evener yarn because this process aligns the fibres better. The combing process is more expensive because it allows for more wastage during the process.

As a rule, we only supply 100% cotton T-shirts unless you request otherwise.

You are most welcome to supply your own T-shirts for printing.

*Please note that dark coloured T-shirts are usually more expensive to print on than lighter or white T-shirts.


The most commonly used printing on t-shirts is screen printing. For the screen-printing process positives must be prepared, silk screens must be manufactured and then set-up manually. This is a labour intensive and time-consuming process and therefore costlier when lower quantities are printed but more economical in larger quantities.

Our minimum order quantities for t-shirts to be silk screened is 20 shirts with designs with up to two colours, and 50 shirts if the design has three or more colours.  The biggest advantage of silk screen printing is that the ink penetrates the material and is then treated with a heat process, this process ensures an extended lifecycle for your print.


When requesting your quotation for silk screen printed t-shirts, please provide us with the following information:

  • Will the artwork be provided in spot or fading colours?
  • The number of t-shirts to be printed.
  • The size of your design.
  • Will you be able to provide the artwork in a print ready, editable vector format?
  • The number of colours in your design.
  • We need to see the design/artwork before sending you a quote.

In cases where you cannot provide the artwork in an editable print ready format, our team of designers can assist you in the re-design the artwork at an additional cost of R 450.00 (Excl. VAT) per hour. The editable artwork will remain your property and can always be re-used, even at different printing companies.


This heat transfer process starts when you digitally print in full colour on a plastic-like vinyl material that is cut into any shape and then transferred to a surface by a heat press. With the heat transfer process, the transfer sheet is pressed at 180°C to 200°C. This is done at a pressure of 1.6 bars.

Video flex offers two main options. The first option is to cut out your design on pigmented video flex (this will not fade in colour, and a variety of more than 30 colours ranging from gloss, matt, glow-in-the-dark, glitter and many more are available to choose from), or secondly you can have your design printed on either a clear (recommended for white t-shirts) or off-white video flex. When you choose cut-out video flex, we have no limitations, although very fine detail in your design is not recommended. The more detail your design entails, the longer it will take for us to do the cut-out, and this is costlier. We prefer to see your artwork before hand to enable us to give you a more accurate quotation.


  • This has a faster turnaround time, compared to other printing methods.
  • Designs print more clearly than with other printing methods.
  • Any artwork format can be used (printable option only), where with the screen-printing method, you are limited to vector format only.
  • On low quantities, Video flex is more cost effective than silkscreen printing, especially when many colours are involved.


  • Not all types of materials can be used to printed using video flex.
  • Some clients dislike the plastic-like surface of video flex.
  • It is advised that you don’t iron, tumble dry, machine wash or dry clean heat transferred products. The best way to wash your garments are by hand in cold water.
  • Artwork with fine outline detail and sharp edges cannot be cut-out. The artwork can however be put in a white block (or another colour) and pressed as a solid artwork.
  • With the printable option the colour starts to fade after a couple of washes.

This is a computer to printer process of T-Shirt printing. This process is usually recommended in cases where the design involves full-colour printing of images or logos and is the costlier of the three processes and does not involve the manufacture of silkscreens and positives as in the case with silkscreen printing.


  • The quality of full colour T-shirt printing is superior than that of screen printing.
  • In cases where you want the same design printed on both adult and kid sized t-shirts it is easier to scale the design up or down with digital printing.
  • This process is ideal when your design includes more than two colours and you want to print relatively low quantities of shirts.
  • This is a computer to printer process where there is no need for the preparation of silkscreens or positive film and therefore has the advantages of a much lower cost, especially in cases where you need low quantities or when your design consists of more than one colour.


  • This process is the costlier than the other T-shirt printing processes.
  • Although this process produces colour fast prints, it is less colour fast than screen printing and more colour fast than full colour video flex printing.
  • The size of your design is the biggest determining factor when in it comes to price unlike in the case of screen-printing, where the number of colours is your determining factor.
