Specifying Artwork and Finish for Custom-Printed Phone Cases

A logo file alone is not a complete production brief. When you source custom-printed phone cases, specify the exact case build, where the artwork sits, how large it prints, what color and finish you expect, and which proof was approved. Tie each item to the actual case construction so your custom phone case manufacturer has less to interpret between sample and production.

The steps below are a practical way to communicate with a supplier, not a universal industry standard. Templates, printable areas, and file rules vary by build and process, so the supplier’s confirmed details should anchor every specification.

Tie Artwork Placement and Scale to the Case Build

Placement and scale only mean something against a specific case. “Centered logo, medium size” can produce different results on a slim hard shell and on a thicker protective case, because the printable surface is not the same. Build the brief in this order:

1. Name the phone model and case construction. Write both in the brief, for example the exact phone model plus the case type and material your supplier uses for that build. Avoid shorthand like “iPhone case” when several builds exist.
2. Request the current template for that build. Ask the phone case manufacturer for the template and printable area that match the named model and construction, and ask how they mark the revision.
3. Annotate position and final dimensions on that template. State where the artwork sits relative to the template’s reference points, such as distance from an edge or the camera cutout, and give the final printed width and height. Use the units the template uses, and add inches if your team works in them.
4. Follow only the boundaries the supplier specifies. If the template shows a safe area or bleed, keep critical elements inside it and extend background art as instructed. If no boundary is marked, ask before you assume one.

When the build changes, request a new template and re-check placement. A layout made for one construction should not be moved onto another unchanged.

Specify Color and Finish for the Chosen Process

Treat your color and finish request as an input, and treat the supplier’s answer as what defines the sample. Keep these two layers separate in the brief:

• Your requested appearance: the finish you want, such as glossy or matte, and the color references your team uses to define brand colors.
• Accepted file and color requirements: ask which file formats, color modes, and color references the supplier can work from for this build.
• Process and surface conditions: ask which print process will be used on the selected case surface, and whether that surface or finish changes how your colors are likely to appear.
• What the sample will show: confirm whether the sample uses the production process, surface, and finish, or only approximates them.

This keeps expectations honest. A color reference tells the factory what you’re aiming for. It does not guarantee that a given process and surface will reproduce it exactly. If the supplier says the sample can’t show the real finish, decide whether you need another sample before you approve production.

Make the Proof Describe the Intended Build

An approved proof is only useful as a reference if both parties know exactly what it represents. Before production, record the approval in one place that you and the supplier both acknowledge:

1. Case build: phone model and case construction.
2. Template revision: the version the artwork was placed on.
3. Artwork file and version: file name plus version number or date.
4. Finish: the agreed surface finish.
5. Proof or physical sample: which digital proof or sample was reviewed, and what production conditions it represents.

Be careful with in-house printouts. A desktop proof is a simulation, and Adobe notes that hard-proof accuracy depends on the printer profile and calibration, including monitor calibration and how closely the desktop printer matches the simulated output device. That guidance covers commercial-print simulation, not phone case printing. So a desktop print is not a substitute for a sample made on the intended case build.

The record only works as a shared reference if both sides explicitly approve it. If any field changes later, update the record and approve it again. You can start that conversation through our store homepage.

FAQs

Should I send vector or raster artwork?

Ask the supplier which formats they accept for the selected process. Vector files usually scale cleanly for logos. Photos are raster by nature, so confirm the resolution the supplier needs at the final printed size.

Can one artwork file cover several phone models?

You can reuse the design, but each build needs its own template, placement, and dimensions. Treat each model and construction as a separate line in the brief and in the approval record.

What if the production run doesn’t match the approved sample?

Compare the production units with the approval record: build, template revision, artwork version, and finish. A clear record makes it easier to tell whether something changed or whether the sample represented different conditions.

Is a digital mockup enough to approve production?

A mockup helps confirm layout. It cannot show how color and finish look on the real surface. If color or finish matters to your brand, ask for a physical sample on the intended build.
