Sublimation Blanks(1000+)

Most mug presses are designed for straight-sided drinkware with a diameter that matches the press sleeve. That typically includes 11 oz and 15 oz ceramic sublimation mugs, and some straight, skinny stainless steel tumblers if your press has a compatible attachment. Certain glass mugs sized like standard ceramics can also work.

• Tapered cups and jars usually don’t seat evenly in a mug press and may need wraps and a convection oven.
• Confirm the blank is sublimation-coated.
• Match the diameter and height to your press element.
• Protect the press with clean butcher paper.

Compatibility can vary by model and coating, so it’s a good idea to check the specs and any press notes listed on the product page.

A little prep can help your transfer look cleaner, but results can vary with your setup:

1. Clean the tumbler with mild soap, rinse, and air dry.
2. De-grease the print area with isopropyl alcohol and avoid touching it after.
3. Align and tape your design tightly; keep the seam straight and secure with heat-resistant tape.
4. Wrap with clean butcher paper to catch any ink bleed.
5. Use a snug press sleeve, wrap, or shrink film as recommended for your press or oven.

Time, temperature, and pressure depend on the blank and equipment. Reviewing the application or care notes on each product listing and doing a single test press before a full batch can help dial in your process.

Care depends on the material and coating, so checking the listing is helpful:

• Ceramic sublimation mugs: Many are noted as dishwasher friendly; top rack and gentle cycles can help, but longevity varies.
• Stainless steel tumblers: Hand washing is generally recommended to help preserve insulation and the printed finish.
• Frosted or color-change glass: Gentle hand washing is often suggested; bamboo lids should be hand washed and not soaked.
• Hardboard coasters, slates, and ornaments: Wipe with a soft, damp cloth.

Avoid abrasive pads and harsh cleaners, which can dull coatings over time. Water hardness, detergents, and cycle settings may affect print life, so consider testing one item first before committing to a care routine.

Dimensions can vary slightly by tumbler, so sizing to your exact blank is a smart approach:

1. Measure height: the printable area between the lip and the base curve.
2. Measure circumference: wrap a flexible tape around the body (or multiply diameter by π).
3. Set margins: subtract about 1–3 mm if you prefer a tiny gap, or allow a small overlap if you plan to blend a seam.
4. Test fit: print a plain-paper wrap and dry-fit it before using sublimation ink.

Check the product page for posted dimensions to speed things up. If you’re using a press sleeve or shrink film, account for compression, which can subtly affect seam alignment.

Reducing ghosting and visible seams usually comes down to tight application and steady handling:

• Choose straight-sided blanks for full-wrap designs to help maintain even pressure.
• Tape thoroughly along all edges, especially the seam, to prevent lift or air pockets.
• Use clean butcher paper to stop ink offset onto equipment or sleeves.
• Control moisture: pre-press flat items briefly; keep drinkware dry and at room temperature.
• Minimize movement while hot; follow your transfer paper’s peel timing (hot/warm/cool) to reduce shifting.
• Design for the join: stagger, feather, or color-match artwork at the seam.

Optimal settings differ by blank and press, so a single test piece can help you refine your method.
