SvarogImpose

Before you start

• Google Chrome on Linux. Tested with Chrome 152 on Ubuntu 22.04; other browsers and operating systems are unverified.
• Extract the entire buyer ZIP and open SvarogImpose.html. The app and its PDF library are bundled and work offline.
• One unencrypted PDF up to 50 MB with one page, or two pages with matching finished sizes. Forms, signatures, active content, automatic actions and three or more pages are refused.

Your first result

1. Open the app and try the example

   Extract the full ZIP and open SvarogImpose.html in Google Chrome. Choose Load the example card. Expect 8 per sheet, 2 columns × 4 rows on A4. The rotated alternative should report nine.

2. Inspect the actual PDF

   Choose Download imposed PDF and open the result in your PDF viewer. Page 1 has the fronts; page 2 has the backs. The in-app diagram shows positions and orientation, not the artwork itself.

3. Load your finished design

   Choose one unencrypted PDF containing one page (front) or two matching pages (front and back), up to 50 MB. Check the detected page boxes and Finished size comes from. Use the TrimBox when correct, the whole page, or the page minus an entered bleed. The design is never scaled.

4. Set up the sheet

   Select a sheet preset or custom dimensions. Set margins, gripper edge and allowance, bleed, row/column gutters, and crop-mark length and offset. Choose automatic fit or fixed rows and columns. The bleed setting cannot create artwork outside the bleed present in your source.

5. Proof the front/back mapping

   Choose left-right or top-bottom turn-over, and head-to-foot if required. Download and print the duplex test sheet at actual size. Measure the result on the target printer and, if needed, enter a back offset up to ±10 mm. Reprint a proof after changing the settings.

6. Export and keep the job record

   Download the imposed PDF and job sheet, or the ZIP containing all outputs. Save the settings JSON for reuse. Check the result in your normal PDF viewer and approve a physical proof before production. The source file is unchanged. To remove the app, delete its extracted folder; keep any jobs you still need.

A worked example

Hollowfen Bindery: eight cards on A4

Input: examples/hollowfen-card-front-back.pdf — fictional 85 × 55 mm card, 3 mm bleed, 5 mm purple slug, front and back with different coloured corners

1. Use the supplied fictional two-page PDF or click Load the example card.
2. A4 portrait, 5 mm margin, no gripper, 3 mm bleed, 0 gutter, crop marks 2 mm offset and 5 mm long, left↔right turn-over
3. Review both schematic sides, export the imposed PDF, and compare it with the expected PDF in the free pack.

Expected result: 8 per sheet (2 columns × 4 rows). The first finished card edge is 17 mm from the left and 29.5 mm from the top of the sheet. Vertical cut lines are at 17, 102, 108 and 193 mm. No slug appears. On page 2 each back's yellow corner sits behind its front's green corner. Rotating the design would fit 9.

Troubleshooting

Compatibility & limits

• Only tested on Google Chrome 152 on Linux; other browsers and operating systems are not claimed
• One design per job; no mixing of different designs on one sheet, variable data, booklets or page reordering
• Does not measure printers or cutters: duplex registration, paper movement and cutting accuracy must be checked with the test sheet and a proof
• Not a preflight or PDF/X tool. Spot colours, overprint and ICC profile preservation are not verified
• Annotations, links, layer visibility, page transparency group settings and the output intent are not carried over (a warning is shown)
• Refuses encrypted, damaged, signed and form-field PDFs; JavaScript, launch or automatic actions; files over 50 MB or with three or more pages. Plain links can be accepted but are not carried over.
• Bleed can't exceed the bleed in the file; designs are never scaled
• The in-app preview is a placement schematic, not rendered artwork. Inspect the exported PDF with your normal PDF viewer before printing.
• Fine hairlines can appear in anti-aliased screen views where bleed edges meet at zero gutter; physical output and cutting remain unverified.
