Two views.
One physical print.

Arrange 2–8 pictures, set lens pitch and print DPI, then create an interlaced image, actual-size PDF and lens pitch-test sheet.

Prepare, test, print

Choose photos or import image files. Select frames, move them earlier or later and adjust each crop. Print setup controls millimeter dimensions, DPI, effective LPI, vertical or horizontal lenses, reversed order, phase, A4/Letter and pitch-test steps. Save and apply print-setting presets.

Create print files generates five local files: interlaced PNG, actual-size print PDF with crop marks, nine-band pitch-test PDF, settings CSV and editable JSON backup with source images. Share all five or individual files through system sharing. Import the JSON to restore a separate copy. The library lets you reopen, duplicate and delete saved prints.

A physical lens and a suitable printer are separately required. Print at 100% / actual size, measure the 100mm ruler on the pitch sheet and test the bands under your lens. Enter the effective pitch before the final print. Frame preview is a manual sequence, not a physical lens simulation. Lens pitch, viewing distance, printer precision, scaling and mounting affect results; compatibility is not guaranteed.

Images up to 20MB and 100 megapixels, retained at at most 1600px per edge. Output is limited to 4096px per edge, sizes20–150mm, DPI300/600/720/1200 and2–8views. Each view needs at least one output pixel per lens. No inferred depth, generated3D, video creation or printer control.

Email maga40@naver.com with the app version, device, print settings and problem. Send personal pictures only when necessary. For printed results, include the measured ruler length and effective lens pitch.

Privacy policy

Effective October 1, 2026. Prismturn is provided by Gobling Company. It does not collect, transmit or upload your images, projects or settings to a developer-operated server. No accounts, advertising, analytics, tracking or third-party SDKs are included.

Photos and files you explicitly select are read on the device. Normalized image copies, frame order/crops, print settings, presets, names and notes are saved in local app storage. Production begins empty; the original day/night example is loaded only when you choose it.

PNG, PDF, CSV and JSON outputs are generated in the local app cache. The JSON backup includes source images and project settings; share it only with intended recipients. System sharing sends files to destinations you choose, whose own privacy terms apply.

Remove a frame to delete its saved source image. Delete a print to remove its saved sources, project and associated cached exports. Delete a preset to remove that saved configuration. Deleting the app removes local app data. Previously exported or shared copies remain at their destinations and must be removed there. Your device backups may include local app data according to Apple or computer backup settings.

If you email support, we receive the information you send and use it to answer. Opening this website sends ordinary web requests to its hosting provider. Neither action is required to create or export a print. Contact the support address for privacy questions.
