Sublimation Blanks : Frequently Asked Questions Answered
Share
We get these questions every day, by phone, by email, and in our inbox at two in the morning from people about to press their first case. This page is the short version. Every answer here is written to stand on its own, so you can grab what you need and get back to your press. Where a question deserves more room, we link to the longer guide.
A quick note on who is answering. We are a family that both makes sublimated products and supplies the blanks. Our daughter Abby started a phone case brand out of the garage in 2019, and in 2025 we bought Innosub USA, the supplier that sold her the first blanks she ever pressed. So when we say something works or does not work, it is because we ran it through a press ourselves.
What are sublimation blanks?
Sublimation blanks are undecorated products manufactured to accept sublimation ink. They are either made from polyester, or made from something else and given a polymer coating that the ink can bond to. A blank is not just any object you own. It is a product engineered so that under heat and pressure the ink becomes part of the surface instead of sitting on top of it.
That bond is the whole point. A sublimated print cannot peel, crack, or wash off, because there is no layer to peel. The color lives inside the coating.
For the full explanation of what happens chemically and why the substrate changes everything, read what sublimation blanks are and how they work.
What materials work for sublimation, and which do not?
Sublimation works on polyester and on polymer-coated surfaces. That covers polyester fabric, coated aluminum, coated MDF, PU leather, neoprene, coated glass, and the hard plastic inserts used in phone cases.
It does not work on untreated natural fibers. Cotton, linen without a coating, leather, and raw wood will take heat but will not hold color, because there is nothing for the dye to bond with. You will get a faded ghost of your design that washes out.
Two clarifications worth having in 2026, because the internet is still repeating old advice. First, poly-cotton blends do work, but the color is lighter in direct proportion to how much cotton is in the blend. A 65/35 blend gives you a soft vintage look, not a vivid one, and that is a design choice rather than a failure. Second, there are workarounds for cotton, including sublimation-friendly heat transfer vinyl and polyester coating sprays. They are legitimate, but they are a different process with different durability, and you should test them before you sell them.
Why choose sublimation over other printing methods?
Three reasons that are particularly important to small businesses:
The print lasts. Because the ink bonds into the material instead of sitting on it, there is no vinyl edge to lift and no screen print to crack. Products hold up to use and washing without degrading the image.
You can print one at a time. There is no screen setup, no minimum run, no plates. One-off personalization costs you the same per unit as a hundred, which is why sublimation is the engine behind almost every custom pet portrait, memorial keepsake, and name-on-it gift you see online.
You can print on shapes. Curved, wrapped, and irregular surfaces are all fair game with the right press or wrap, and the equipment is less expensive than other printing methods such as UV.
There are a few trade-offs, and one of them is color range. Sublimation cannot print white, and it cannot print onto dark substrates with any accuracy. Your blank color is your background color. Plan designs around that instead of fighting it.
The other consideration is your substrate. Sublimation requires a polymer coating or polyester content in order to bond properly. This means you have to source blanks that are specifically designed for sublimation.
What can you actually print on?
Far more than most people starting out realize. Here is where our catalog sits today, grouped the way our customers typically shop:
- Phone cases: iPhone, Samsung, and Google, plus phone case accessories and spare inserts
- Tech accessories, including wireless charging pads, watch bands, earbud cases, and stands
- Pet accessories: collars, leashes, and tags
- Apparel and bags and totes
- Home and garden and kitchen and bar
- Keychains and nametags, jewelry, and school and office
- Games and toys, automotive, and photo frames and signage
- 3D printing blanks for full-wrap designs
If you would rather just look at everything, there is our full catalog and what we added most recently.
One pattern worth knowing before you build a product line: our customers typically purchase products in clusters. Depth inside one category outsells breadth across many, and that holds true whether you are buying from us or selling to your own customers.
What equipment do you need to start?
There are four basic components to start with:
A sublimation printer. Either a dedicated unit or a converted inkjet running sublimation ink. Do not run sublimation ink through a printer you also want to use for regular printing, because you cannot go back. We recommend the Epson EcoTank line because they are relatively inexpensive and are easy to fill and convert for sublimation.
Sublimation paper. It is coated to release the ink cleanly under heat. Regular paper holds onto the ink and gives you a muddy transfer. Quality paper will be thick and have a fast drying time to avoid smudges in the print.
A heat press. There are a wide variety of heat press options on the market and most will do the job. You need a flat heat press for most 2D sublimation or a vacuum heat press for 3D sublimation. We offer a few options and you can also find deals on Facebook Marketplace or similar sites.
Blanks. As mentioned, you need to have blank products that are specifically coated for sublimation or have a high polyester content.
Heat presses, consumables and pressing supplies are in printing supplies, and if you are shipping finished product, we offer some shipping supplies as well.
Start with one product you understand, get it consistent, then widen out. If you are weighing whether this is a business or a hobby, we wrote about starting a sublimation business from home and how to pick a niche and grow it.
What is a heat press, and what settings should I use?
A heat press is a machine that applies a controlled temperature and an even, measured pressure for a set number of seconds. That combination is what converts the solid dye to gas so it can enter the coating. A household iron cannot do this, because it cannot hold an even temperature across the whole surface or apply consistent pressure, and uneven pressure is the single most common cause of a blotchy first print.
Settings depend entirely on the substrate, not on the design. As a starting point from our own testing:
| Substrate | Temperature | Time | Pressure |
|---|---|---|---|
| Aluminum | 385°F / 196°C | 35 seconds | Medium |
| MDF | 350 to 360°F / 176 to 182°C | 60 to 70 seconds | Light to medium |
| PU (vegan) leather | 360°F / 182°C | 45 to 60 seconds | Light to medium |
| Linen | 360°F / 182°C | 40 to 50 seconds | Medium |
| Neoprene | 385°F / 196°C | 35 seconds | Light to medium |
| Glass | 360°F / 182°C | 60 to 100 seconds | Medium |
Treat these as your starting point and adjust for your press, because two presses set to the same number rarely read the same temperature at the platen. The complete list, with notes and video walkthroughs, is on our heat press settings page. If a press comes out wrong, troubleshooting covers ghosting, insufficient heat, pressure problems, and overprint residue with photos of what each failure looks like.
Two things that are not on the settings chart but decide your results anyway. Tape your transfer down, because a transfer that shifts even slightly during the press gives you a double image. And get the design placed correctly before you press, which is what our free printing templates are for.
Can I do sublimation at home?
Yes. Most of the businesses we supply started on a kitchen table or in a spare bedroom, and a fair number are still there and doing well.
What you need in practice: a dedicated surface that can take heat, a standard outlet that is not shared with other high-draw appliances, ventilation, and somewhere to let pressed items cool flat. Presses are heavy and get hot, so a folding table is a bad idea and a solid one is worth the money.
The real constraint on home sublimation is not space. It is consistency. Pressing ten cases perfectly is easy. Pressing two hundred identically, in the same session, and having them all match, is the skill. That comes from writing down what worked and repeating it, not from better equipment.
How do I know if a blank is any good?
Look at the coating, not the price. A cheap blank is almost always a thin or unevenly applied coating, and it will show up as color that looks washed out even at correct settings, or as a print that looks fine on one unit and dull on the next from the same box.
Three things we would check on any supplier, including us:
Consistency across a batch. Order a small quantity first and press several from the same lot. If they do not match each other, they will not match for your customers either.
Whether the supplier presses the product themselves. There is a real difference between a company that resells a container of blanks and one that runs the material daily and knows which SKUs are difficult. We are in the second group because we still make and sell finished products under our own brand.
Whether they will tell you what does not work. Any supplier happy to sell you a blank they know presses badly is not a supplier.
