An artwork file should travel with enough information to reproduce its intended composition, not just a filename and a request to print it. At minimum, the production brief may need the exact approved version, orientation, dimensions, crop boundaries and selected edge treatment. Include any critical detail that must remain visible on the front. A clear handoff prevents a technically printable file from becoming an unintended design after trimming, wrapping or stretching.
Identify the exact image and its intended composition
Use a descriptive file name or version reference that clearly distinguishes the approved image from drafts. A family portrait may exist as an original camera file, a retouched copy, and several crops. Stating only use the latest photo invites confusion. Record which version contains the approved edits and keep the source unaltered for comparison. If the photograph includes people, artworks, or third-party imagery, the person supplying it must also establish appropriate permission for the proposed reproduction.
Specify orientation and composition in a visual way where possible. A simple marked proof can show which area must remain on the visible front and whether the surrounding image may continue toward the sides. Draw attention to essential facial features, inscriptions, signatures, and historic image borders near any possible crop. If a design includes lettering, supply the approved exact wording and intended line breaks. These are content instructions, not merely numerical measurements.
Give technical information that is genuinely useful
Physical size and the underlying pixel dimensions affect whether the original image has enough detail for the proposed presentation. Record the pixel width and height and the requested visible print dimensions. Do not invent a universal minimum resolution for every canvas printer, image type, or viewing distance. Ask the producer to evaluate the source for its actual process. Resizing cannot reveal original detail that was never captured, and an altered file's PPI label alone does not guarantee quality.
For a landscape with a narrow lighthouse near the edge, write a note such as 'keep the complete lighthouse visible on the front; do not wrap it around the side.' Attach an annotated crop that marks the required feature and specify the intended orientation. That is more actionable than sending a file named final-final and writing 'make it look good.' File version, trim guide and side treatment should all identify the same approved composition.
Color information may also matter. Provide the source file with its available embedded profile intact, and tell the producer if particular neutrals, portraits, or brand colors are critical. A reference proof can help clarify expectations, but a screenshot from an uncalibrated device is not an exact color specification. If a particular print finish, coating, or edge method is desired, request confirmation that it is offered and identify the selected option accurately in the order record.
Prevent approval misunderstandings
A concise instruction note can separate nonnegotiable details from acceptable adjustments. For example: preserve the entire quotation and both faces; moderate tonal adjustments may be reviewed before output; do not invent a different background. This guidance is better than telling a producer to make it look good without context. Document who approved the proposed crop and whether any later change requires renewed signoff. The decision record should stay alongside the exact file version.
If the image combines work by several people, clarify who supplied the parts and whether their reuse is permitted. Do not infer copyright ownership from possession of a digital image or from a social-media upload. A business may also have limits on file format, content, color workflows, or production options that a general FAQ cannot verify. Keep those requirements in a separate confirmed supplier checklist, rather than pretending the editorial guidance is an actual Wallpics upload policy.
The most useful delivery package is a specific image plus unambiguous visual instructions. It explains what must be visible, what physical presentation is intended, and which choices need confirmation. That allows a provider to flag a mismatch early instead of interpreting a vague file name after printing has already begun.
