What is Sublimation?

Sublimation is a printing process where heat is used to transfer dye inks onto materials like polyester fabric, ceramics, metals, or specially coated surfaces. It involves converting solid dye into gas without going through the liquid phase — hence the name sublimation.

What You Need for Sublimation

1. Sublimation Printer
   Must be a printer specifically made or converted for sublimation.
   Popular brands: Sawgrass or Epson.
2. Sublimation Ink
   Only use sublimation-specific ink. Standard inkjet ink won’t work.
3. Sublimation Paper
   Special paper designed to hold and release sublimation ink efficiently.
4. Heat Press Machine
   Used to apply heat and pressure to transfer the design.
   Flat press for shirts, coasters, placemats & keyrings etc
   Mug/tumbler press for curved items.
5. Design Software
   Adobe Illustrator, Photoshop, or Coral Draw
6. Blanks (Items to Print On)
   Must be polyester-based or polymer-coated.
   Examples: Tea Towels (at least 65% polyester), Placemats, Mousepads, Coasters, Keyrings

Sublimation Process Step-by-Step

Step 1: Create or Import Your Design

• Use your software to design or download high-resolution, mirrored images.
• CMYK colour mode is ideal for accurate prints.
  

Step 2: Print on Sublimation Paper

• Print the mirrored image using sublimation ink on sublimation paper.
• Let it dry for a few minutes.
  

Step 3: Prepare the Blank

• Ensure the surface is clean, dry and free from dust.
• Use lint rollers for fabrics and alcohol wipes for hard surfaces to remove any residue that may effect sublimation.
  

Step 4: Align and Tape the Print

• Position the sublimation print face-down onto the blank.
• Use heat-resistant tape to keep it in place.
  

Step 5: Heat Press the Item

• Follow specific time/temp/pressure settings depending on the blank:
  Example (T-shirt): 400°F for 45-60 seconds, medium pressure
  Mug: 380°F for 180 seconds
• Use protective sheets (like Teflon paper) to prevent ink bleed.
  

Step 6: Peel & Reveal

• After pressing, peel off the paper (usually hot peel).
• Admire your vibrant, permanent design!

Aftercare Tips

• Wash sublimated apparel inside out in cold water.
• Avoid bleach or strong detergents.
• Sublimation designs won’t crack or peel — they’re infused into the material.
• Material Care Notice: Sublimation coatings on MDF, aluminium, fabrics, ceramics, and other substrates can react differently to UV light. While some materials offer better UV resistance than others, none are fully UV‑proof.
• Direct sunlight may cause fading, yellowing, or warping depending on the product. Indoor, shaded placement is recommended for maximum durability and do not put in direct sunlight .
• Note: Direct printing by UV printing and using UV coated items reduce effects of UV and direct sunlight as this uses pigment inks rather dye-sublimation inks and is a different printing process and is more resilient to UV and sunlight

Common Issues & Fixes

Issue	Cause	Solution
Blurry images	Design not sharp enough	Use higher DPI/resolution
Ghosting	Paper shifted during pressing	Use more heat tape
Incomplete transfer	Not enough pressure or time	Adjust press settings
Faded design after washing	Not polyester, or ink not fully sublimated	Use higher polymer content

Heat Press Settings: Safe Ranges for Common Blanks

Every supplier varies slightly, but these ranges work for most products:

Product Type	Temp	Time	Pressure
Polyester T‑shirts	180–200°C	45–60 sec	Medium
Mugs (11oz)	180–200°C	180–240 sec	Medium
MDF	180–200°C	60–90 sec	Medium
FRP	180–200°C	45–70 sec	Light–Medium
Acrylic	180°C	60 sec	Light
Mouse Mats	180–190°C	45–60 sec	Medium
Bar Runners	180–190°C	60 sec	Medium
Coasters	180–200°C	60–90 sec	Medium
Tote Bags (polyester)	180–190°C	45–60 sec	Medium

Care
Always sublimate/press in a well ventilated area and if necessary, wear heat protective gloves as substrates do get very hot after being in a heat press.

We do offer a guide to heat press settings on each of our products, but this will vary between what press you use, what inks and paper is used.

Sometimes a bit of trial and error is needed before you find your correct settings.

Material‑Specific Care

MDF / Hardboard Products

Not waterproof — avoid contact with water.

Clean gently with a dry or lightly damp cloth.

Keep away from heat sources and direct sunlight to prevent warping.

Aluminium Products

More durable but still avoid abrasive cleaners.

Wipe with a soft cloth and mild detergent if needed.

Indoor display recommended for best colour retention.

Ceramics

Hand‑wash only unless specifically marked as dishwasher‑safe.

Avoid abrasive sponges on printed areas.

Do not expose to sudden temperature changes.

Fabric Products

Tote Bags

Wash inside‑out on a cool, gentle cycle.

Use mild detergent; avoid bleach and fabric softeners.

Air‑dry to maintain colour vibrancy.

High heat can dull sublimation dyes over time.

Tea Towels

Machine‑wash on a gentle cycle with mild detergent.

Avoid bleach or stain removers containing optical brighteners.

Tumble dry on low or hang to dry.

If ironing is needed, iron on the reverse side only.

 

Sublimated Bar Runners & Mouse Mats

Cleaning

Most fabric‑top runners can be machine washed on a cold, gentle cycle.

Use mild detergent only.

Let them air dry — the rubber base can warp in a dryer.

Stain Handling

Treat spills quickly with warm water and a soft cloth.

For sticky alcohol residue, a gentle soap solution works well.

Avoid scrubbing aggressively — it can roughen the printed surface.

What to Avoid

No bleach or stain removers.

No tumble drying.

Don’t fold them — store flat to prevent creasing.

Mouse Mats

Core principle: Sublimation is permanent, but the surface fabric still needs gentle care.

Cleaning

Wipe with a damp cloth and mild soap for everyday marks.

For deeper cleaning, hand‑wash in lukewarm water with a gentle detergent.

Avoid soaking for long periods — the rubber backing can warp.

Air‑dry flat, away from direct heat.

What to Avoid

No bleach, no harsh chemicals.

No machine washing — many mats curl or delaminate.

No tumble drying — heat can distort the rubber base.

Avoid prolonged direct sunlight to prevent fabric fading .

Longevity Tips

Keep away from sharp objects that can snag the fabric.

If the mat curls, place it under a heavy book overnight — don’t apply heat.
