Name document size and finished size
If a graphic is designed at one tenth of full size, a 600 × 200 mm document represents a 6,000 × 2,000 mm output. Write both pairs of dimensions, units and the 1:10 scale in the handover. Do not make the print operator infer the scale from a filename or from a familiar banner product.
Scale the dependent geometry deliberately
Bleed, safe areas and finishing features must follow the agreed template convention. Confirm whether the provider’s template is already reduced or whether you must create reduced values. Effective resolution must be assessed at the final output size. A pixel image that appears adequate in the small document may lose that effective resolution when enlarged.
Test one understandable record
Use the scale calculator to check the arithmetic and export the values with the job ticket. Compare the aspect ratio to the confirmed system and label orientation. If the document and output proportions disagree, pause and resolve the cause rather than applying an arbitrary stretch. The accepted technical specification should name the final geometry independently of a screen preview.
Worked example — fictional
A fictional backdrop is required at 5,000 × 2,500 mm. The provider asks for a 1:10 document, so the design size is 500 × 250 mm. A provider-confirmed full-size bleed of 40 mm would correspond to 4 mm in the reduced document if that is the agreed template convention. The handover states both sizes and the 1:10 scale. A photograph 2,000 pixels wide covering the full backdrop has an effective output width resolution of about 10.16 PPI, regardless of how sharp it looks when the reduced page fits on a monitor. The team therefore asks the provider to assess the actual file and viewing requirement. The example shows why scale, finishing geometry and raster resolution need connected records rather than a lone reduced PDF attachment.
Decision checkpoints
- Scale notation: record the relationship in a form another operator can interpret without guessing.
- Document geometry: confirm the reduced dimensions match the selected template’s expected size and units.
- Final geometry: name finished physical dimensions independently of the file’s small page size.
- Image check: calculate effective resolution using the final placed size and actual retained pixels.
Common pitfalls
- A file named 10-percent can still contain the wrong dimensions, so verify its actual geometry.
- Scaling only the panel outline while leaving finishing allowances unchanged can alter the intended construction.
- Automatic stretching can hide an aspect-ratio disagreement and distort content without resolving the underlying requirement.
Use it on your next job
Enter the final dimensions and scale in the resize tool, then compare the result with the actual document. Ask the provider how bleed and safe areas should be represented. Include document size, output size, ratio and template revision in the job pack. Pause any release whose proportions disagree with the accepted equipment or application.
Take this to the next job
- State the scale explicitly
