T-Shirt Screen Printing – What’s Involved



If you’re looking for Brisbane screen printing, then it’s probably a good idea that you find out exactly what the process involves before making a purchase. Screen printing is a process that uses a woven mesh to hold an ink restricting stencil to transfer a chosen image to fabric.

The Technique

Art creation – This stage is where you design the art intended to be used for printing. It’s important to choose a design that will translate well, and either a hand-drawn or computer generated image can be used. When screen printing T shirts, it’s also critical that when translating this design to film that the film is 100% black in the right areas, as light can pass through and semi cure your emulsion which can be impossible to wash out. Film to T shirt transfers are where most issues can occur so it’s definitely better to be overly cautious here.

Choosing the frame and mesh -  For this part it’s important to have a rigid frame, and one where the mesh is tightly secured. The performance of your screen will define the quality of your print, and choosing a printing store that has invested into their frame and mesh will allow you to push the limits with your design and creativity. 

Prepping the screen – This is where the mesh is gently abraded with a mild abrasive while cleaning off any potential dirt or grease. Once this is complete it is set to dry in a room that is absent of any dust or other particles, to ensure that it is clear enough to receive the emulsion.

Setting up the press – A press operator uses a scrap shirt and prints just one colour while aligning the other screens. This process is called registration, and once the screens are registered, the ink is added to the frame and a sample is run with the entire colour spectrum. Any adjustments can be made at this point to make sure everything is lined up perfectly.

Running the press – Each shirt is loaded onto a pallet for printing, and then goes on to make its way around the press, stopping at each head (or section). A different colour is used at each head, where the ink is pulled across the stencil made on the frame. This is repeated, and once the shirt has been through the entire colour spectrum it is placed through a dryer with extremely high temperatures that are necessary to cure the ink.

This is the general process of screen printing and in general it can be done relatively quickly, depending on the quantity of shirts you require. Overall, it pays to invest in a service that has quality equipment and materials, so you get exactly what you're looking for with the design.

An Introduction to Digital Fabric Printing


Digital fabric printing is a relatively new form of printing that offers technology with a huge amount of applications. In this article I will discuss the technology and design process that is used with this method, and examples of why this might be beneficial as a form of printing over the other methods available.

Technology

 Digital printing has a great advantage over the standard rotary screen printing due to the technology that it uses. Because there are no screens to prepare, users are able to do very small runs of a design for testing, rather than being forced into a huge print to save costs.


The inks used are created specifically for each type of fiber (cotton, nylon etc), and these are applied to the fabric in the form of thousands of little droplets as it passes through the printer. Once this is completed, the fabric is then finished using steam and/or heat to cure the ink. Digitally printed fabric will usually wash and wear similar to most other fabrics, however occasionally there can be some fading in the first wash with specific ink types.

Design Process

Creativity can be pushed in the designs, as they are able to be created with almost any graphic design software (such as Adobe Photoshop or Adobe Illustrator). Existing photographs or artwork can also be scanned and then manipulated to make a pattern.

In general designs are created as a pattern that is repeated or tiled across the fabric. It is also possible to create a huge design that fills a large area without repeating, however this can cause issues if the file of the design is too large for the printer to handle.

Overall, this method is an excellent way to go when deciding about how to approach printing onto fabric in Brisbane. Digital printing allows you to not only push the boundaries in the design stage but also test a variety of these designs easily and efficiently without spending too much time in doing so.
