What is Discharge Printing?
Here at Fifth Column, we love printing t-shirts, it’s in our DNA. And we love all aspects of the art. One technique which is increasingly popular is discharge screen printing. Okay, we know, that begs a question. What is discharge printing? Well, read on and we’ll tell you everything you need to know about this fascinating form of screen printing and the discharge printing process. In simple terms, discharge printed t shirts are created using the screen print method but done so with a special ink. Specifically, discharge printing ink which reduces the dye in the garment and replaces it with the ink colour. As an aside, some folk refer to discharge printing as extract printing.
One of the key characteristics of discharge printed clothing is the soft hand feel of the finished article. These soft prints differ from those achieved with more traditional ink in that the dye is absorbed into the material rather sitting on the surface. As a consequence, you can’t feel the printed design when you run your hand over the garment. Plus, discharge print commonly has a rather beautiful, retro-inspired vintage vibe which people absolutely adore. Something that’s a must for certain artwork, those designs that simply won’t properly work with a surface-proud, plasticky feeling print.
What are the advantages of discharge printing?
Following that, we really ought to have a closer look at the qualities which make discharge printing t shirts such an attractive option. Whilst discharge print won’t suit every project, it’s definitely got a lot of devotees and is gaining admirers all the time.

Is Discharge Printing Eco-Friendly?
The answer is yes, in context. It’s fair to say that there are aspects of discharge printing t shirts which are friendlier to the environment than some of the alternatives. For example, plastisol inks are no longer acceptable in certain circumstances. To explain, the latter contain PVC which is considered by many to be an extremely toxic substance. That’s to say, making and getting rid of it can be dangerous and potentially harmful activities. Which is avoided by using water-based discharge printing ink. Another eco-friendly t-shirt printing tick is that it’s possible to combine eco pigments with them. So, is discharge printing toxic? The answer is no more so than other methods if handled thoughtfully with an environmentally acceptable approach to such things as the bleaching process.
