Custom size poster
Upload your poster artwork
Resolution is judged at the size you chose above. Grow the poster and the same file may stop being sharp enough.
Try it
- Upload the low-res image at the default 50 × 70 cm, borderline.
- Grow the poster to 100 × 150 cm: same file, now clearly not sharp enough. Resolution is relative.
- Upload the A1 sample and shrink the size, suddenly everything passes.
Sample files
The two products staying in their lanes: the price comes from the size you type, never from the file; while Filecheck judges whether your artwork is actually sharp enough at that size.
Change any option and Filecheck re-checks the same file without
re-uploading. Add ?fcdebug=1 to the URL to see what
it is told about your selections.
How this page is wired
The Filecheck element owns the page; the Print Options form reacts over its public Page API. The blueprint (one JSON document) still declares both: the options with their prices, and the inline Filecheck workflow this page runs.
intake.on('status', s => {
po.setFile(factsOf(s)); // facts reprice the form
s.canProceed ? po.releaseHold('filecheck')
: po.addHold('filecheck');
});
po.addEventListener('change', e =>
intake.setContext(contextOf(e))); // selections re-check the file
