About Your Custom Heat Changing Mug

    Magic heat changing mugs come with either a navy blue or black base colour that covers your design. Only when filled with hot water will your image be revealed, so when it's not in use your mug will appear either blue or black. When you're designing your custom heat change mug, view your creation as both hot & cold to get a clear idea of how it'll look aesthetically in its different forms. Made from solid white ceramic, they are durable, contemporary mugs.

We print your design onto a special blue or black layer that reacts to heat, so choose your base tone here.

How your Colour Changing Mugs are Printed & Made

We print your bespoke designs onto a special layer that reacts to heat, changing from the base colour to white when filled with your hot drink of choice. Only the body of the mug has this layer, so your handle remains blue or black. We package them up in their cold state so all you will see is either black or blue when it first arrives, ideal if you're creating one for a surprise. As the heat sensitive mug is activated, the reveal starts at the bottom and the base colour magically starts to vanish.
Please note that the blue or black base colour isn't completely opaque, and the outline of your design might come through slightly, more so if you select blue.

Care Instructions

Please do not put in the dishwasher. Clean by hand using mild soapy water to help preserve the life of the print and prevent chipping. 

  • Hand Wash

Design Tips

Your unique design wraps around the body of the mug, only leaving a small gap when it reaches the handle. We don't print on the handle as this could distort your beautiful design. The full height is covered leaving almost no white space at the top or bottom of your mug. A clever idea would be to print a secret message with the first word placed at the bottom, that way the sentence can be read as the heat sensitive mug works its magic. 

As the outline can be seen slightly, we'd suggest opting for designs that feature lighter, more subtle colours. However, it's only slightly visible and the effect isn't diminished because of this. 

If you're in the wedding business, the custom heat change mug is a fun addition to your product range, as they can be used for proposals, maid of honour requests or hen party reveals. Simply create colour changing mugs with various slogans and quotes and add them to your range. You can also use them for hospitality as they'd be a popular talking point among guests. Print a special greeting to guests welcoming them to the event, or use them creatively for a competition whereby only one mug has the winning symbol.

How does this product enhance my...

  • Home

    With the custom heat changing mug you get 2 in 1. When the mugs are cold, your kitchen cupboards are neat, tidy and uniform and when you use them, all the family can experience a different design. Sometimes, certain mugs get overused and others are underused, however as these all look the same when cold, you don't know what you'll get.

  • Business

    Create a buzz at your business event with heat sensitive mugs. As delegates sip their tea or coffee, they'll be greeted with a special message from your company. If the nature of your business involves revealing something new, like a hair salon, bridal boutique or gym, these mugs are a clever and subtle nod towards experiencing a transformation of some sort.

  • Design Brand

    These heat changing mugs leave everything to the imagination, perfect if you're an artist who likes to provoke thought and opinion. Have your paintings, drawings or conceptual art printed onto these mugs for a novel way to sell your art. Not everything is what is seems with heat activated mugs, and you can create some real drama when presenting them.

Frequently asked questions:

How do heat sensitive mugs work?

We print your design onto a special layer that reacts when hot liquid is poured in. Once activated, it slowly disappears revealing your design.

Is my design totally concealed?

You choose from either a blue or black base tone. Your design is slightly visible under both colours, but less so with the black base.

Can I print on the handles too?

The heat activation only occurs on the body of the mug, so your handles will remain either blue or black, depending on the selected base colour.

Print Guideline

  • DPI-Print Guideline Icon

    What's the best resolution to print in?

    We print at 200dpi, which is a good combination of quality and file weight. Ideally, your image should be scaled to 100% at 200dpi, this means that no resizing of your file occurs stopping any interpolation.

  • Jpeg-Tiff Print Guideline Icon

    Should I save my file as a TIFF or JPEG?

    For multi-coloured or very detailed files we recommend using a tiff format, but they must be flattened. For simple colours and low detail files, a jpeg is fine.

  • RGB-CMYK Print Guideline Icon

    Which colour model should I choose? RGB or CMYK?

    We advise providing images in the RGB colour space. Specifically using the sRGB image profile, to achieve best colour results.What does this mean? In your editing software choose RGB as the working space, and assign the image profile as sRGB (full name sRGB IEC61966-2.1)


    What does GSM mean?

    Grams per Square Meter (GSM) is an international standard for measuring the weight of paper or fabric. GSM uses the weight of a square meter (1000 x 1000mm) as an indication of the weight and thickness of a given fabric. We class 20-100gsm as light (summer fabrics, gauzes and fine silks), 101-249 gsm as medium (most clothing fabrics) and 250+ gsm as heavy (upholstery fabrics, and other specialist fabrics).

  • Fill Bleed Areas ICON

    What are bleed areas?

    When designing your product, it’s best to make sure that your image is slightly larger than needed. In printing, the extra printed image is referred to as a “Bleed Area” or margin, and it is removed from the finished piece. A bleed area acts as a buffer for slight inconsistencies in the manufacturing process. however, it’s important to fill your bleed areas completely, or you may end up with white, unprinted strips along the edge of your finished product.

  • Transfer-Print Guideline Icon

    Do you print on garments a customer supplies?

    Unfortunately not. All our garments are printed on flat fabric and sewn into finished products, which gives a better-finished result and all-over print. We test meticulously so that we know what gets the best results on our fabrics, and our facilities cater perfectly to them. We do however print sublimation paper to order, so if you have access to a heat press you can press your fabrics or flat garments easily.

  • Pattern Alignment Across Seams ICON

    Can you Align a Pattern or design across panels of a garment?

    We always strive for the greatest accuracy when printing and constructing your garments. However, due to unavoidable stretch or movement of the fabric during the stitching process, we cannot guarantee perfect pattern registration across garment seams. We are generally accurate within 2-3mm, which is close enough for most patterns but may show slight issues with detailed geometric patterns.

  • print label option icon

    Can I print my own Labels?

    Most of our garments now come with printable label space for you to add your own company information and branding. If you would like to sew in your own labels, we also offer Printed Fabric Labels here.

  • Eco friendly Printing

    How is your fabric printing eco-friendly?

    With environmental consciousness in mind, our fabrics are all printed using completely water-based inks. This means no chemicals or solvents are used. Our heat fixing procedure fixes the colours and prints, avoiding the downsides of steaming, such as excess or contaminated water returning into the waste system. We have one facility where we conduct all the printing, production and fulfilment.

Please note: As everything we provide is handmade to order, all measurements may vary slightly.
