An image export can pass every file check and still fail as a physical artwork. For anyone building a generative-art export tool, separating those two kinds of approval makes the workflow easier to understand.
Whispart develops GAN-based images and gives selected works a physical form. Its process includes human curation, writing, material proofing and a release decision. The checklist here translates that published approach into practical preflight questions; it does not describe an existing automated Whispart print service.
Calculate resolution at the intended size
Pixel dimensions describe a file. Physical dimensions describe an object. The relationship is:
effective PPI = pixels along an axis / (print size in cm / 2.54)
For an illustrative 4096 × 4096-pixel image:
| Square print size | Effective PPI, rounded |
|---|---|
| 40 × 40 cm | 260 |
| 50 × 50 cm | 208 |
| 60 × 60 cm | 173 |
These are arithmetic examples, not Whispart product specifications or pass/fail thresholds. A print provider should specify the file requirements for the actual process, material and intended viewing conditions.
If the image is cropped, calculate from the pixels that remain. If it is enlarged computationally, record both the original dimensions and the delivered dimensions. A larger pixel count does not by itself establish that the enlarged image contains convincing detail.
Changing only a file's resolution metadata does not add pixels. A useful export interface should therefore show the intended physical size beside the dimensions, rather than celebrating a “300 PPI” label in isolation.
Separate the front image from the edge treatment
A stretched canvas introduces a second geometry problem: what appears on the front, and what is reserved for the sides or finishing process?
Keep the approved complete image separate from any production derivative. Ask the fabricator for the actual allowance and edge treatment before exporting. Do not assume that every canvas depth or frame uses the same dimensions.
A review should make any crop visible. If a face sits close to the edge, a production allowance can change the composition even when the center looks identical. A preview that shows only the front rectangle can conceal that problem.
Give each check a truthful result
| Check | What software can report | What still needs inspection |
|---|---|---|
| File opens | Decoding succeeded; dimensions read | Whether the image is the intended version |
| Size calculation | Effective PPI for the selected crop and size | Whether the print is convincing at the intended distance |
| Crop preview | Which pixels remain on the front | Whether the altered composition is acceptable |
| Color preparation | The file's declared profile and export settings | The result on the actual material under real light |
| Production proof | A proof record has been attached | Whether the proof deserves approval |
“Check completed” and “approved” should be separate states. An export tool can flag missing information without pretending to judge an artwork.

Close the loop with the physical object
The Whispart journal's account of physical proofing distinguishes room visualizations from physical evidence. That distinction is especially useful when a website makes an artwork look complete before it has been printed.
Attach the inspected proof to the exact file version, intended size, material and date. Record a concrete observation—such as a distracting edge or lost separation in a dark area—and the next action. If the file changes, do not silently carry the old approval forward.
For a practice that authorizes one physical release of a selected image, the decision to release deserves its own record. A successful export is an input to that decision.
