Sublimation Temperature Chart: Settings for Every Substrate (2026)

Updated: July 20, 2026

A reliable sublimation temperature chart is one of the most useful things you can have next to your heat press. Getting the temperature, time, or pressure wrong by even a small amount can mean the difference between vibrant colors and a faded, blotchy, or scorched transfer.

The tricky part is that sublimation settings are not universal. A ceramic mug needs completely different settings than a polyester shirt, and even two brands of “11oz white mugs” can behave differently depending on their coating. The settings in this chart are practical starting points based on widely used standards, but always check your blank supplier’s recommendations if they provide them.

Below you will find settings for many of the most common sublimation substrates, organized by category. Bookmark this page or save a screenshot for your craft room.

Complete Sublimation Temperature Chart (2026)

This chart covers the most common sublimation substrates with recommended starting settings. These are general guidelines. Your specific heat press, blank brand, and environment (especially humidity) can all affect results. When in doubt, start at the lower end of the temperature range and do a test press on a scrap piece first.

Tip: screenshot this chart or bookmark this page. Having your settings visible next to your heat press saves time and prevents mistakes, especially when switching between different substrates during a session.

Fabric Sublimation Settings

All fabric sublimation requires polyester content. The higher the polyester percentage, the more vibrant the colors. A 100% polyester shirt produces the sharpest results, while a 60/40 cotton-poly blend gives a softer, more vintage look with less color intensity.

For all fabric pressing, pre-press for 5 seconds without the transfer paper to drive out moisture. This step prevents fading and ghosting. Place butcher paper inside the garment to prevent ink from bleeding through to the back side, and place butcher paper on top to protect the heat platen.

After pressing, peel the transfer paper in one quick upward motion while the fabric is still hot. Dragging or slow peeling on hot fabric can cause ghosting. Full care instructions for keeping sublimated shirts looking good are in the washing sublimation shirts guide.

Drinkware Sublimation Settings

Mugs and tumblers need longer press times than fabric because the coating takes more time to absorb the ink through the thicker substrate. With drinkware, removal timing depends on the blank and the method. Ceramic mugs are often allowed to cool down briefly after pressing, while shrink-wrapped tumblers are often stripped as soon as practical so the paper does not stick.

For ceramic mugs, a mug press or a dedicated convection oven are the most common methods. Some crafters also use an air fryer as a budget alternative. Tape the transfer down so it cannot shift, then let the machine supply the pressure: the heated element in a mug press, or a fitted silicone wrap or shrink sleeve in an oven. In an oven, shrink wrap or a silicone sleeve is what creates even pressure around a stainless tumbler. In a tumbler press the machine supplies that pressure itself, and the tape only holds the transfer in place. For complete mug settings including enamel and color-changing mugs, see the mug temperature and time guide.

Tip: mug press temperatures can vary significantly between brands. Measure the real platen temperature with heat test strips or a surface contact probe: an infrared gun is unreliable on a shiny platen, because reflection and surface finish distort the reading. Check several spots, not one, since platens can vary across their surface. If your press displays 400°F (204°C) but actually runs at 380°F (193°C), your colors will come out faded and you will blame the paper or ink when the problem is the press.

Hard Substrate Sublimation Settings

Hard substrates like acrylic, glass, metal, and ceramic share one important rule: the coating is everything. The same substrate from two different suppliers can need different settings because the coatings vary. Always check the supplier’s recommended settings if available.

Acrylic is the most temperature-sensitive hard substrate. Go too hot or too long and the acrylic warps, sometimes beyond saving. For Unisub cast acrylic, the published setting is 350-360°F (177-182°C) for 120 seconds at medium pressure: cooler and roughly twice as long as most blanks. Other coated acrylic products run differently (Sawgrass lists 375°F for 60 seconds for generic acrylic), so acrylic is not one recipe. Use the sheet that came with your blank because heavy pressure on hot acrylic causes deformation.

Glass and ceramic tile blanks often need much longer press times than fabric, but exact settings vary widely by coating, thickness, and blank style. Rushing the cool-down after pressing can cause the print to look hazy.

What Happens When Settings Are Wrong

Understanding what goes wrong at each extreme helps you diagnose and fix problems quickly:

Pre-Press Checklist (Especially Fabric; Some Hard Blanks)

Run through this before every press, regardless of what you are making:

1. Check your temperature. Verify the displayed temperature matches your actual platen temperature if possible. Budget heat presses can be off by 10-20F.

2. Pre-press when the blank calls for it. For fabric, a short 3-5 second pre-press is standard to remove moisture. Some hard blanks also benefit from a brief pre-press and full cool-down before transfer, while others are normally pressed without a separate pre-press step.

3. Secure the transfer paper. Use heat-resistant tape on all edges. For mugs and tumblers, tape the transfer. In an oven, add a fitted wrap or shrink sleeve; in a press, the machine itself supplies the pressure. Paper shifting is one of the most common causes of ghosting.

4. Check whether the design should be mirrored. Most sublimation transfers are mirrored and placed face-down, but some back-coated glass blanks are exceptions. Always check the blank instructions.

5. Use protective paper. Butcher paper on top of the transfer and inside garments prevents ink contamination of the heat platen and bleed-through.

Tip: the first few times you sublimate a new substrate type, do a test press on a scrap piece. Every heat press behaves slightly differently, and the 5 minutes you spend testing saves you from wasting an expensive blank.

How to Use This Chart (and Where These Settings Come From)

Every setting here was checked in July 2026 against manufacturer and blank-supplier documentation, and corrected where it did not match. The sources are listed below. Even so, these are starting points, not rules: presses run hotter or cooler than they read, coatings differ between suppliers, and humidity changes the result. Always test one piece before you commit an expensive blank, and when your blank comes with its own instruction sheet, follow that sheet over any chart, including this one.

For reference, Sawgrass publishes an official heat press settings reference (PDF). The process is called dye-sublimation, though what matters for your press is simply this: the dye is driven into the coating rather than sitting on top of it, and that only happens inside the right temperature and time window for the material. Getting that window right is what this whole chart is for.
