Got a mind blowing design for a t-shirt? Great! Time to move that design from computer to cotton!
There are lots of different ways to apply a graphic design to a blank t-shirt. In this guide, we’ll explain the difference between screen printing, vinyl transfers, dye sublimation and DTG digital printing. You’ll learn the pros, cons and limitations of each print method so that you can shop around with confidence and pick the very best option for your business.
There are some technical reasons to choose one print method over another, but the biggest reason is probably product quality. The way in which a blank t-shirt gets printed has a massive impact on the durability, comfort and finish of the product you’re trying to sell…
The more you know about the basic differences between dye sublimation, digital printing, screen printing and vinyl transfer, the better your product will be … it’s that simple!
There is no perfect t-shirt printing method. Every method is good in certain situations and bad in others. A lot of it depends on the blank t-shirt you want to use and how you want the finished product to perform. For instance…
So, with all of the different options available, how do you choose? Well, we have good news for you: we’ve made a t-shirt print method picker which you can download and keep!
On this grid, you can see what each print method will and won’t do. Depending on what’s important to your business and to your customer, you’ll be able to pick the right print method in a matter of seconds:
This checklist will give you a steer, but it’s no replacement for actually holding a physical product in your hands.If in doubt, try to get a few t-shirt samples made up. That way, you can see and feel the difference for yourself.
When you dye sublimate a t-shirt, you get a permanent design that never rubs off. Your design will last as long as the t-shirt does, because dye sub ink stains the individual fibres that make up your t-shirt.
The whole process of dye sublimation relies on special inks that are designed to vaporise at a high temperature. First, your design gets printed onto your blank garment. Next, the garment gets heated up until the dye sub ink transforms from a solid into a gas. This coloured gas is thin enough to penetrate the fibres in the individual threads of your t-shirt, and stain them with whatever colour you choose. When the t-shirt cools down again, the ink solidifies and you’re left with a permanent design that looks great for years to come.
There are a few issues with dye sublimation. You can’t print white, which means that you can’t sublimate on dark shirts. It’s a bit like trying to paint with watercolours on black paper — the artwork just won’t show through . If you want to use dye sub as your tee printing method, you need a white, light grey or pastel-coloured shirt.
Dye sublimation also doesn’t work on cotton t-shirts. The special ink will only bond to polyester. If your tee is a poly-cotton blend of at least 70% polyester you should be OK, but check with your printer first.
Vinyl transfers are like die-cut stickers for your t-shirt. With vinyl, you place your transfer directly onto the fabric of your shirt, then apply heat to get it to stick. Some transfers use heat-activated adhesives, and others will need to be ‘melted’ onto the garment. Either way, your vinyl graphic will sit on top of the fibres of your t-shirt. It won’t penetrate the fibres like dye sublimation.
If you want to print every t-shirt yourself, you could do it using vinyl transfers. You would either need to work with an online vinyl transfer company (someone who can die-cut your vinyl for you and send you a ‘sticker sheet’ of transfers), or you would need to invest in a cutting plotter or cutting machine to die-cut your decals yourself. You would then need a t-shirt heat press to bond the vinyl to each shirt.
Vinyl is a great way to get vivid, punchy colours onto a dark t-shirt. It’s also a very cost-effective option if you’re working with small designs like pocket details and sleeve decals, because you can squeeze lots of die-cut decals onto a single sheet of vinyl.
Screen printing works by cutting out a stencil on a very fine mesh sheet known as a silkscreen. You place that stencil on top of your blank tee, then paint your ink across the stencil to decorate your shirt.
Screen printing gives a softer finish than vinyl, and it works on any type of t-shirt (cotton, poly or blends). It also allows you to print bright colours onto dark tees. If it’s cured correctly, a screen printed t-shirt will look sharp for years.
Screen printing generally only lets you print a 4-colour or 6-colour design, depending on the machinery that your printer is using. It also takes time to set up your kit for the first t-shirt. Every silkscreen needs to be created individually and calibrated, which takes time. As soon as the setup process is complete, you can produce a lot of high-quality tees at speed.
With DTG, or Direct-To-Garment, printing, you can pack as many colours as you want onto a t-shirt, and you can achieve high levels of detail too. DTG is a very good compromise between the speed of dye sublimation and the vibrancy and versatility of screen printing.
There’s very little setup work involved in DTG printing. All you need to do is spray your garment with a pre-treatment spray , then print it on a special printer. After the printer has finished, you heat the garment, and the ink and treatment form a permanent bond with your t-shirt’s fabric. The whole process of spraying, printing and cooking a shirt takes a couple of minutes.
DTG and screen printing deliver very different finishes, so if you’re trying to choose between the two options, get your hands on a sample of each. Your t-shirt will breathe and feel differently depending on which print method you choose.
That’s it for this week! Now that you understand the difference between the main printing methods, you’ll be able to go and get quotes from a few different printers.
