A thin, kiln-fireable image printed on water-soluble backing paper and sealed with an inorganic covercoat. When soaked in water, the image releases from the paper and can be positioned face-up on a glazed ceramic surface, then permanently fused in a kiln firing.
Ceramic decals have been used in commercial tableware manufacturing for over a century. Brands like Limoges and Wedgwood have long relied on them to apply intricate, repeatable artwork to porcelain. What was once exclusively an industrial technique is now accessible to independent potters, ceramic artists, and hobbyists — and digital printing has expanded the possibilities dramatically.
Unlike a tissue paper transfer (applied face-down), a waterslide decal is released from its backing and applied face-up — meaning the image appears exactly as it was printed, with no mirroring.
The decal sits on top of the fired glaze as a third firing. After the kiln firing, the covercoat burns away completely, and the mineral pigments fuse directly into — and permanently bond with — the glaze surface beneath.
How Ceramic Decals Differ from Vinyl & Paper Decals
It's worth clarifying: ceramic decals are not the same as vinyl stickers, screen-printed paper labels, or sublimation transfers. Ceramic decals use inorganic mineral-based toners that can survive kiln temperatures of 800°C–1300°C. The result is a glass-like, permanent surface — not a coating that sits on top.
The Three Main Decal Printing Methods
All ceramic waterslide decals are fired the same way — but how the image is printed onto the backing paper has a huge impact on color fidelity, minimum order quantities, detail level, and cost. There are three methods you'll encounter:
Digital Decal
Full-color CMYK printing using mineral-based powdered toners. No screens, no setup fees. Ideal for photographs, gradients, and complex illustrations.
Strengths
- Unlimited colors
- Photo & gradient support
- No setup fees
- Single sheet orders
- Upload & order online
Considerations
- Best on light glazes
- Slightly matte texture
- No metallic colors
Silkscreen — Overglaze
Dense opaque toners pressed through a mesh screen. The commercial tableware standard, great for spot colors, metallics, and high-contrast graphic designs.
Strengths
- Very dense color
- 23K gold & luster
- Sharp, crisp edges
- Works on dark glazes
Considerations
- Per-color screen cost
- No gradients
- High minimums
- Limited to ~8 colors
Silkscreen — Inglaze
Fires at high temperature (Cone 04–10), causing the image to sink into the glaze. Creates a soft, fluid look reminiscent of traditional Delftware.
Strengths
- Fused into glaze
- Extremely durable
- Classic aesthetic
- High-fire compatible
Considerations
- Soft/blurred edges
- Very limited colors
- No photo-quality
- Screen setup costs
Digital Decals: A Deep Dive

Digital ceramic decal printing uses a modified laser printer loaded with powdered mineral toners — the same inorganic pigments used in silkscreen printing, but applied via a CMYK electrostatic process. This unlocks the full visible color spectrum, including photographic gradients and subtle tonal shifts that are completely impossible with silkscreen methods.
What Makes Digital Different
Traditional silkscreen printing creates color by layering flat, opaque spots of a single toner. There's no mixing — a blue screen and a yellow screen overlap to create green, but with hard edges. Digital printing blends four base mineral toners (Cyan, Magenta, Yellow, and Black) at a microscopic level, producing over 16 million possible color combinations in a single pass.
Photographic Detail, Fired in Glass
Because the toner is applied as fine powder and fused with a liquid covercoat, digital decals can reproduce photographic images, watercolor washes, subtle gradients, and complex multi-color illustrations that would require dozens of silkscreens to approximate.
After kiln firing, the inorganic mineral pigments become part of the glaze surface — the same permanence as silkscreen, with the color flexibility of inkjet printing.

Digital Decal Surface Texture
One characteristic worth knowing: digital ceramic decals have a subtly matte, slightly textured surface after firing. This is because powdered toner has a slightly granular quality compared to the liquid inks used in silkscreen. The texture is minimal and adds to the handmade quality many ceramic artists love — but it differs from the glass-smooth surface of a silkscreen overglaze decal.
Color Density & Glaze Considerations
Digital toners are somewhat less optically dense than silkscreen toners. For the most vibrant color results, digital decals perform best on white, cream, or other light-colored glazes. On dark glazes — cobalt, black, deep teal — colors will appear muted or may not be visible. If you fire on dark clay bodies, a white underglaze or light-colored slip makes an excellent base.
Silkscreen Decals: Overglaze & Inglaze
While digital decals are what we print and sell, understanding the full landscape helps you make informed decisions — especially if you're a ceramic artist who also works with commercial suppliers or production studios.
Silkscreen Overglaze Decals
Silkscreen printing uses a tightly-woven mesh screen with areas blocked out to form the design. Liquid toner is pushed through the open areas of the screen onto the decal paper. Each color requires its own screen.
The result is an extremely dense, opaque color — more vivid and saturated than digital, particularly useful for solid blocks of color and high-contrast graphic designs. Silkscreen overglaze also supports metallic toners: 23K gold, platinum, and copper luster finishes that are simply not achievable with digital printing.
The tradeoff: silkscreen requires custom screen creation for each design, significant minimum order quantities (often 50–500 sheets), and significant lead times. It's designed for production runs, not one-off custom orders.
Silkscreen Inglaze Decals
Inglaze decals are a specialized silkscreen variant that fires at much higher kiln temperatures — Cone 04 through Cone 10, reaching 1920°F to 2340°F (1050°C to 1280°C). At these temperatures, the image literally sinks into the glaze rather than sitting on top. The edge of each color becomes soft and blurred as it melts into the glaze surface.
This creates a look reminiscent of classic Delftware or hand-painted majolica — soft, watercolor-like imagery with a fluid, integrated quality. It's extremely food-safe and durable since the design is encapsulated within the glaze itself. The palette is very limited, however — many pigments cannot survive the high-fire process.

When to Choose a Digital Decal
Digital decals are the right choice in a wide range of situations. Here's a quick guide:
You need full-color, photographic, or gradient imagery
Any design with more than 8 colors, soft shadows, watercolor textures, or photographic detail can only be reproduced via digital printing. No silkscreen equivalent exists at any price point for this complexity.
You're making a small batch or a one-of-a-kind piece
Silkscreen setups cost hundreds of dollars before a single sheet is printed. Digital has zero setup fees — ordering one sheet is exactly as cost-effective per unit as ordering fifty.
You want to prototype before committing to a production run
Use digital to validate the design on the actual ceramic piece first. Once you're satisfied, scaling to silkscreen for large runs is a logical next step — but only after you've confirmed the image works.
You're personalizing a piece for a client, event, or gift
Pet portraits, wedding photos, family crests, botanical illustrations, personal artwork — digital decals make one-of-a-kind ceramic personalization practical and affordable.
You need quick turnaround
Because there's no screen creation, artwork review for screen separation, or minimum quantity to meet, digital orders can be processed and shipped within days rather than weeks.
How to Apply a Ceramic Waterslide Decal
Applying a ceramic decal is a simple process, but a few key steps make the difference between a perfect result and a frustrating one. This applies to all decal types — digital, silkscreen overglaze, and inglaze.
Start with a clean, already-glazed surface
Ceramic decals are a third firing — applied over an existing fired glaze. Your piece must have been bisque fired and glaze fired before decal application. The glaze surface should be clean, dry, and free of dust or oils.
Clean the ceramic surface
Clean the glazed surface with 91% isopropyl alcohol. Wipe down the entire area where the decal will be applied to remove fingerprint oils, dust, and residue that can prevent the decal from adhering evenly. Allow to dry completely before applying the decal.
Cut out your decal
Trim the decal as close to the design edge as you like. The excess clear covercoat around the design will be invisible after firing, but keeping margins minimal helps prevent trapped air bubbles.
Soak in warm water for at least 30 seconds
The image will begin to uncurl from the backing paper — this is your signal it is ready. Don't over-soak; you want the decal sliding freely but still on the paper when you lift it out.
Slide the decal onto the ceramic surface, face up
Hold the backing paper against the ceramic and use your finger to gently slide the decal off the paper and onto the piece. Position it where you want it before it dries — you have a short window to adjust.
Squeegee out air bubbles and excess water
Use a soft squeegee, a damp makeup sponge, or your fingertip to gently press from the center outward, removing trapped air and water. Avoid anything abrasive. Any bubbles left in will show as lifted areas after firing.
Let it dry completely before loading the kiln
Allow at least 1–2 hours of air drying before loading the kiln. The decal should appear completely flat with no visible moisture.
Fire to 1555°F (846°C) for digital decals or Cone 018 (1470°F / 800°C) for silkscreen overglaze
For digital decals, ramp at 200°F/hr (95°C/hr) to 788°F with kiln vented, 0 hold. Then 285°F/hr (140°C/hr) to 1555°F (846°C), hold 15 minutes, and cool naturally. For silkscreen overglaze decals, fire to Cone 018 (1470°F / 800°C) using the schedule recommended by your supplier.
File Preparation Guide
For the sharpest possible digital decal, your file setup matters. Here's everything you need to know before uploading.
Tips for the Best Results
Use transparent backgrounds where possible. The covercoat applied over the entire decal will be invisible after firing, but a white background will show as a white rectangle around your design. If your design has irregular edges or a cutout shape, export as PNG with transparency enabled.
Avoid very pale or light colors near the design edge. Light yellows, pale pinks, and soft gradients that fade to white can be difficult to control during printing and may disappear or show uneven edges. Add a 1–2px stroke or keep important detail away from the outer margin.
Remember: colors will shift slightly after firing. Mineral toners don't behave identically to digital screen colors. Reds and oranges are particularly prone to shifting warm. Testing a small design on a matching glaze before committing to a large order is always worthwhile.
Pack your sheet efficiently. Since you get one Letter sheet, design your layout to make the most of the space. Tiling small designs, placing multiple variations, or including both a test strip and a full composition on one sheet is a common and savvy approach.
Firing Temperatures Explained
Kiln temperature is the single most important variable in successful decal firing. Each decal type has a specific firing range — firing too hot will destroy the design; firing too cool will leave the covercoat intact and bubbled.
A note on ramp rates: For overglaze and digital decals, the ramp through 300–788°F is critical. Moving too fast through this range can cause the covercoat to bubble and trap gases, resulting in a blistered or pitted finish.
Frequently Asked Questions
Are digital ceramic decals food safe? +
Yes. Our digital ceramic decals use lead-free mineral toners. Non-metallic colors are food safe when properly fired. However, as with any overglaze decoration, we recommend hand-washing to preserve the finish over time. The decal sits on top of the glaze rather than embedded within it, making it slightly more susceptible to abrasion than inglaze methods.
Can I use digital decals in a microwave or dishwasher? +
Digital decals (non-metallic) are generally microwave safe and top-rack dishwasher resistant. For longest-lasting results, hand-washing is recommended. Repeated high-heat dishwasher cycles can eventually cause surface wear on overglaze decorations.
What if my design has white areas? Will white print? +
White is not a printable color in CMYK digital ceramic printing — there is no white toner. Areas of your design that are white or transparent in your file will simply not have any toner, allowing the glaze beneath to show through. If you need white to appear as white, you need a white glaze beneath those areas. This is one of the key reasons digital decals work best on light-colored or white glazes.
Can I cut a digital decal into a custom shape? +
Absolutely. The decal paper itself can be cut with scissors or a craft knife to any shape you like. This is commonly used to create decals that wrap around a curve, fit a specific area of a piece, or to separate multiple designs printed on the same sheet for individual application.
Do I need a special kiln for overglaze decals? +
No — any kiln that can reach 1555°F (846°C) is suitable. Electric kilns are ideal because they allow precise temperature control. Gas kilns can be used but require careful atmosphere management. The most important factors are accurate temperature measurement (use a properly calibrated thermocouple or witness cones) and a slow initial ramp rate.
What's the difference between a decal and a tissue paper transfer? +
A tissue paper transfer is applied face-down — the image is pressed onto the clay or glaze surface, then the paper is peeled away, leaving a reversed impression. A waterslide decal is soaked in water, slides off its backing paper, and is placed face-up — the image appears exactly as printed, with no mirroring. Ceramic waterslide decals also use kiln-fireable mineral pigments that permanently fuse to the glaze; tissue paper transfers are often temporary or require different firing processes.
Can I order a digital decal of a photograph or copyrighted image? +
We can print any image file you upload. You are responsible for ensuring you own or have appropriate rights to the image. Photographs you have taken, original artwork you have created, or licensed images with appropriate use rights are all suitable. We cannot reproduce copyrighted commercial artwork, trademarked logos, or licensed character art.
How many designs can I fit on one Letter sheet? +
As many as you can fit on the Letter canvas (215.9 × 279.4 mm). Small repeat designs can be tiled dozens of times on a single sheet. Multiple different designs can be placed on the same sheet and cut apart after printing. We print exactly what you upload — the layout is entirely your choice.
