Screen Printing Frequently asked Questions
The list is designed to help you get the right information and inform you on some of the most Screen printing frequently asked questions.
Q: What is Screen Printing?
Screen printing is a form of stenciling that first appeared in a recognisable form in China during the Song Dynasty (960–1279 AD). It was then adapted by other Asian countries and was furthered by creating newer methods.
Whilst the Screen printing has advanced and the methods have progressed, the key principals of the traditional screen printing methods still apply.
Screen Printing is a process in modern day where a polyester mesh is stretched over an aluminum frame. This screen then gets coated with a light sensitive emulsion. The emulsion once dried, then allows for a film positive (Your Image/Logo) to be applied to the screen. The screen is then exposed to a UV light source, which intern burns/etches Your Image/Logo onto the mesh.
Once the screen has successfully been exposed, processed, blocked and taped, it is then ready for print production. The screen is then placed in the machine where it is set up to start the printing process.

Our team will then begin printing your garments and or items through the manual or semi-automatic screen printing process. This process is the transfer of ink through the Screened image onto your substrate.(E.g. T-shirt, Singlet, Jumper etc) To find out more, please contact us today.
Q: What types of inks are used in screen printing?
There are several types of screen printing inks, depending on the substrate that is required to be printed on, we will use a standard ink or one of our specialised inks to best suit the item.
Q: What is a PMS Colour:
A PMS colour stands for Pantone Matching System, which is a world wide colour matching system. This enables Printer, Designers and Clients the ability to select colours that correlate universally for their particular design, logo or image. Eg. A client in Europe has a Blue Colour of PMS 286C, this colour can be matched exactly to the Blue shade depicted in the PMS colour book, here in Brisbane. This is a critical part in Screen Printing, and it is encouraged that all customers are able to provide PMS colour matches for their decoration before production.

Q: Why do I need a White Base?
When printing vibrant colours on black or dark garments it is often necessary to print a white under base first. This is due to the fact that many plastisol textile inks do not have the opacity to cover well on dark garments. A white under base is nothing more than a white spot colour print in the shape of the artwork for which the colour is intended. It is printed first to provide a base for the coloured ink to rest on. The under base is flash cured before the remaining colours are printed.
Q: Why do I need a Grey Base?
When printing on Cool Dry, Polyester (100%, 50/50, 65/35), Sublimated and Athletic garments we have discovered that in their manufacturing process these garments are often very heavily loaded with dyes and once exposed to heat in the Screen Printing process, these uncured dyes can re-activate causing the dyes to leach into the print colours effectively changing the colour of the prints which we call “Dye Migration”. Our specialised Grey Base stops this from happening ensuring that the intended print colour stays the same and is not affected by the garment.
We also recommend using a Grey Base on all Red, Maroon, Bottle Green and Purple garments whether they are cool dry, cotton or pique.
