For custom keycaps, material and printing method are part of the design decision. DIYKeycap's listed custom set uses PBT, a Cherry profile and dye-sublimation printing. Understanding those specifications helps you prepare artwork and ask useful questions before ordering.
What dye-sublimation means for your design
Dye-sublimation uses heat to transfer dye into the material rather than creating a second molded plastic legend. PBT is used for this printing process. It can support illustrated and multicolor artwork, but the final result still depends on the specific production method and design. Do not assume that every effect, finish or color combination can be reproduced without a feasibility review.
Design for legibility, not only the preview
Start with a clear difference between the legend and background. Check tiny text, fine lines and subtle gradients at keycap size. If the design spans the keyboard, remember that the image is divided by gaps and individual key shapes. Keep important details where they remain visible during normal use.
Set realistic color expectations
A backlit display and printed plastic reflect color differently. Screen settings, room lighting and the keycap surface can affect what you see. Send color references and identify priority colors; ask how those references will be reviewed for the project. An attractive digital render is useful for composition but is not a physical color proof.
Catalog examples for project discussion. Ask DIYKeycap to confirm the selected material, legends, key inventory and keyboard model.
Check material, profile and layout separately
PBT describes the material; Cherry describes the profile; ANSI or ISO describes a layout family. None of those labels alone confirms compatibility. DIYKeycap's listed set offers 129-key ANSI and 156-key ANSI/ISO options. Compare the actual key inventory with your keyboard's stem, Enter, Shift, spacebar and bottom row.
Use a simple pre-order review
- Check the exact keyboard model and key sizes.
- Review legends, logo placement and any artwork spanning multiple keys.
- Confirm the available material, profile and printing specification.
- For bulk work, agree sampling, color review and production terms in the project quote.
Choose the specification before drawing
Make a short specification card with five separate items: keyboard model, physical layout, key inventory, profile and printing requirement. PBT is the plastic; the profile describes the key shape and height; the inventory lists the keys supplied. A material name does not tell you which Enter key or spacebar is included.
For DIYKeycap’s listed custom set, compare the 129-key ANSI and 156-key ANSI/ISO diagrams before choosing your artwork template. The extra keys in the larger inventory help cover more arrangements, but do not automatically provide every local-language legend or unusual key size. Use the actual model, not simply “75% keyboard,” to request a compatibility check.
Ask the right questions about colour and lighting
If you want light lettering on a dark background, send that exact combination for review. Do not assume that a printing-method label guarantees every background, gradient or edge treatment. Ask which parts of the key can be printed and whether the proposed design suits the selected production route.
If you need illuminated legends, ask whether the specific product has shine-through lettering. “PBT,” “custom” and “dye-sublimation” alone do not establish that feature. A keyboard’s lighting can be visible between keys without shining through the letters. This is a separate buying decision from whether the artwork is readable under normal room lighting.
Use a colour review that records what matters
- Provide the original colour references, rather than a screenshot from a messaging app.
- List the most important colour relationships, such as readable dark legends on a light background.
- Review artwork placement separately from the physical colour result.
- Ask what sample or proof arrangement is available, what it represents and which design version it covers.
- Record the agreed specification before production. A changed background or material may require another review.
The white MDA examples pictured above illustrate a different profile from the listed Cherry-profile custom set. They are catalog references, not colour proofs or finished samples of your design. Do not use them to infer identical shape or production terms.
A practical full-keyboard artwork check
As a design exercise, imagine an illustration across a compact keyboard. Place the main subject where key gaps are less likely to split its important features, then inspect Enter, Shift and the spacebar individually. Keep functional legends readable. Review both the complete image and each key, including any supplementary keys used on another keyboard. This is an illustrative exercise, not a customer case study.
When comparing a ready-designed set with a custom project, start with our PBT keycap selection, then check each product’s actual specifications. For a regional project, also review the German, French, Spanish or Italian layout guide.
Discuss your project with our factory
DIYKeycap has its own factory and accepts bulk custom keycap projects. Send your company name, quantity, keyboard models and layouts, artwork, delivery country and target date. Minimum quantity, price, sampling, lead time and packaging are confirmed for each project.
