Start with a model-by-design matrix
List each exact phone model as a separate row. For each row, record the artwork version, planned quantity, color direction, and the person who can approve that combination. Avoid a single line such as “latest iPhones, assorted designs”: it leaves the mix impossible to price or review consistently.
If quantities are provisional, mark them as estimates and show the range you are considering. Ask the printing team which models and case options it can quote for your project. A design approved on one model should not be assumed to transfer unchanged to every camera layout.
Identify the final artwork and who may use it
Give every file a descriptive name and revision number, such as summer-campaign-front-v03. State which file is final, who owns or licenses each image and typeface, and whether text must remain editable. If a photo, logo, or slogan belongs to a client or creator, secure permission for the planned use before it enters production.
Share the best source file available and label low-resolution references as references. Do not infer that an image suitable for a website is suitable for printing. Ask the supplier for its actual file format, color, resolution, and template requirements before preparing a final production file; this guide does not set those technical limits for OneTwo.
Describe what must survive changes in case shape
Mark the focal point, important text, and any elements that must not be cropped. State whether the background may extend or shift around the camera opening. A simple annotated preview can show which details are negotiable and which are essential. Keep a separate note for each model whose camera arrangement changes the composition.
Do not treat a flat artwork image as proof of final placement. Request a model-specific proof or other approval method from the printing team, and confirm what can be changed after approval. If a photo includes a face or a logo has a required clear space, call that out explicitly.
Agree on one approval path
Name one person to consolidate comments. Ask what proof will be provided, which details it represents, how revisions are handled, and when artwork becomes approved for the order. Put the final file name and revision in the approval record so an earlier draft cannot be mistaken for the release version.
Keep commercial questions alongside the artwork questions: required models, quantities, target timing, delivery destination, and whether the order is one run or likely to repeat. The quote comparison worksheet explains how to compare offers using the same assumptions. Any sample, production timing, packaging, or fulfillment request needs separate confirmation; none is implied by this checklist.
A brief you can send
- Project: intended use and the contact who can approve artwork.
- Matrix: exact phone models, design IDs, and estimated quantities by combination.
- Files: final candidate artwork, revision numbers, rights status, and reference images clearly labeled.
- Placement: focal points, text, crop restrictions, and model-specific questions.
- Approval: proof and revision questions, target timing, and delivery destination.
OneTwo Tech Inc. operates phone case UV printing at its Walnut and Chino, California locations. See the U.S. business printing page for confirmed locations and the inquiry route. Send a project brief to the team and ask which specifications and terms it can support. Do not ship materials or visit either location without arranging that with the team first.
