Six small supplies do most of the protecting around a DTF press: PTFE sheets, heat tape, a T-shirt alignment ruler, a reusable lint roller, a heat press mat, and heat press pillows. Together they cost far less than the press itself, and each one guards against a specific mistake. All six are on my Sublimation Starter Kit list on Amazon.

What does a PTFE sheet do in DTF pressing?
It sits between the press and your work as a protective layer. Marie Gems transfers press at 320°F for 15 seconds with a cold peel, which is hot enough that a slip of film or adhesive can end up on the platen. The HTVRONT PTFE sheets come as a three pack of 12x16 inch sheets, so one covers a 12 inch transfer, and they were about $6 as I write this. A cheap sheet is easier to replace than a scorched shirt.
How do you keep a transfer from shifting?
Tape it down before the press closes. Heat tape is made to survive the temperature, so it holds a transfer in place while you close the press. The MEBMIK heat tape is a six roll set, about $10 as I write this. Shifting is the classic pressing mistake, because a transfer that moves as you swing the press closed cannot be repositioned once it bonds.
How do you place a transfer straight?
Use a ruler made for it instead of eyeballing the center of a shirt. The Vowlove T-shirt alignment ruler is listed as being for DTF transfers ready to press, and it was about $10 as I write this. A crooked design is the kind of flaw that a customer notices immediately and you notice only after the press is open, so a ruler earns its place quickly.
Why lint roll a shirt before pressing?
Loose fibers and lint trapped under a transfer show up in the finished design. A quick pass with a reusable lint roller, like the Nyosye reusable lint roller, clears the surface first. Reusable matters because it is something you reach for on every single garment, and a sticky sheet you peel and throw away adds up.
What are a heat press mat and pillows for?
They shape what happens under the platen. The HTVRONT heat press mat is a 15x15 inch double sided mat, about $20 as I write this, and it gives the press a stable surface to work against. The SUNHE YHK heat press pillows come as a four pack in four sizes, and pillows raise the area you are pressing so seams, zippers, and buttons do not sit under the platen. Reach for them when a garment has hardware or thick seams near the design. My Benable lists carry the same kind of supplies. My DTF Business Starter Kit list includes heat press tape, silicone parchment paper, and heat press pillows, and my note on the pillows says they even out the pressure around buttons, zippers, and seams so you are not getting a lighter print at the edges. My Sublimation Must Haves list has a Teflon sheet, sublimation tape, and a lint roller.
What do these supplies cost together?
Not much. As I write this, the PTFE sheets, heat tape, alignment ruler, and mat add up to about $46 together, at roughly $6, $10, $10, and $20. I am leaving out the lint roller and the pillows because I do not have a current price for either, so check those listings. All six are on my Sublimation Starter Kit list, and prices on Amazon change, so treat these as rough numbers.
Which of these should you buy first?
Buy the PTFE sheets and the heat tape first, since they prevent the two costly mistakes, scorching and shifting. Add the ruler and the lint roller next, because they fix small errors on every press. The mat and the pillows are for when your work calls for them. That order covers the mistakes that cost you a garment first and the ones that cost you a crooked design second.
The bottom line on heat press supplies
These are small, cheap, and easy to skip until the first ruined garment. If your process is still forming, start with protection and placement, and add the rest as your products ask for it. These sit on a sublimation list, but they work with any heat press method, DTF included, and DTF vs. sublimation vs. HTV explains how the methods differ. For the whole process these supplies sit inside, how ready-to-press DTF transfers are made walks through it.
