Frequently asked questions

Highlights for 1.2.3 (17 May 2026):

• Smart Preflight v2 — colored summary panel (Passing / InfoOnly / WarningsOnly / Critical) + top-5 prioritized actions in imperative form.
• Content-based bleed detection — the app inspects real extent of images and glyphs and compares it to TrimBox/BleedBox. New issue codes: BLEED_CONTENT_UNUSED, BLEED_CONTENT_OVERFLOWS_BLEEDBOX.
• Template suggestion from PDF — Tools → Suggest template from PDF. 25 presets with confidence scoring.
• N-up Layout Optimizer — in the template editor, "Optimize N-up" tries both orientations and picks the denser packing.
• Trim/Bleed preview guides — cyan dashed (TrimBox) + magenta dotted (BleedBox). Independent toolbar toggle.
• Manual update check — Help → Check for updates (tri-state result).
• Duplex roll-fed/N-up fix — 2-page PDF + 12-up + duplex → 1 sheet with 12 fronts + 12 backs (was: 2 separate sheets).
• Preview UX polish — 1-based counter, side toggle in spread view, CMYK bars inside the paper, overview placeholder from 25% zoom.

Full step-by-step instructions in Help → What's new.

Above the issue list, a colored panel adopts one of four moods:

• ✓ Passing — no issues, ready to print.
• i InfoOnly — informational notes only.
• ⚠ WarningsOnly — warnings without blockers.
• ✕ Critical — errors that may stop the RIP.

Below the mood you get a top-5 prioritized list of actions in imperative form (e.g. "Add 3 mm bleed to source file"). Clicking an action jumps to the matching issue. Full details: Help → Preflight v2.

Menu Tools → Suggest template from PDF…. The engine analyses:

• page size (TrimBox or MediaBox, ±2 mm tolerance),
• side ratios (e.g. 1.41:1 → A-format, 1:1 → square),
• page count (multiple of 4 → saddle stitch, >40 → perfect bound, 3 → trifold),
• bleed presence (BleedBox > TrimBox),
• spot channel presence (e.g. white-under-varnish for stickers).

Returns 1–5 proposals ranked by confidence 0–100%. Full preset list: Help → Template suggestions.

In the template editor, for a given item size, sheet size, margins and gutter, it tries both portrait and landscape orientations and picks the one that fits more pieces.

Formula: cols = floor((sheet_w − 2·margin) / (item_w + gutter)), rows analogously, N = cols × rows. The larger N wins; ties go to portrait.

Example: business card 85×55 on SRA3, 8 mm margin, 3 mm gutter — portrait gives N=20, landscape N=21 → landscape picked. Details: Help → Layout optimizer.

Yes — since 1.2.3 the preview toolbar has an independent Trim/Bleed guides toggle (shortcut: T):

• ━━━ cyan dashed → TrimBox (cut line)
• ··· magenta dotted → BleedBox (bleed extent)

Off by default to keep the view clean — turn on only when checking bleed/trim placement. Together with Preflight v2 it gives you full control over the cut area.

Menu Help → Check for updates…. The app queries the GitHub API and shows one of three states:

• Update available — with a changelog link and a "Download & install" button.
• You're on the latest version — nothing else to do.
• Check failed — no internet, GitHub down or rate-limit.

Independently, the app checks for updates once per day silently in the background. You can disable it in File → Settings → Updates.

In versions 1.2.0–1.2.2, a 2-page PDF with 12-up + duplex produced two separate single-sided sheets — not usable in production.

In 1.2.3 GangingStrategy pairs pages in sequence (1+2, 3+4, …) and produces 1 sheet with 12 fronts on the front side and 12 backs on the back side. The stats panel correctly reports 1 physical sheet with 24 impressions. The regression is locked down with a unit test.

imPRESS Studio is a professional PDF imposition tool that lays out document pages on press sheets per a chosen template (saddle stitch, perfect bound, folding) and exports a print-ready PDF.

Target users:

• Digital and offset print shops
• DTP studios and advertising agencies
• Photographers preparing albums and photo books
• Self-publishing authors
• Freelance designers preparing print artwork

InDesign is a publication-design tool — imposition is not its core function and requires extra plugins or external tools.

Acrobat handles basic N-Up at print time but doesn't produce a full imposition with signatures, creep, registration marks, etc.

imPRESS Studio is a dedicated imposition tool — it does one thing precisely, with full control over templates, margins and marks, without needing the entire Adobe Creative Cloud subscription.

• OS: Windows 10 or later (64-bit)
• Runtime: .NET 8 (self-contained build, no separate install)
• RAM: 4 GB minimum, 8 GB recommended for large files
• Disk: ~200 MB + space for PDFs
• Optional: Ghostscript 10+ for PDF/X-4 conversion

We're focused on Windows for now. The app uses Avalonia, which technically supports macOS and Linux — those targets are on the roadmap but unscheduled. If you need a non-Windows build, let us know — it helps prioritization.

1. Visit github.com/dnblsr-lab/imPRESS-Studio/releases
2. Download the latest imPRESS_Studio-Setup.exe from the Assets section
3. Run the installer (Inno Setup) — wizard lets you pick the install folder, add desktop and Start menu shortcuts
4. On first launch the activation window appears — paste a Trial or production key

After install the app auto-checks for updates on launch and installs them silently in the background (same GitHub Releases source).

The official distribution channel is GitHub Releases:

github.com/dnblsr-lab/imPRESS-Studio/releases

Each release ships imPRESS_Studio-Setup.exe plus a changelog. The app uses the same URL for auto-updates.

1. Email impress_studio@proton.me with subject "Trial 30 days", or use the contact form
2. Install the app, run it — the activation window shows your machine ID
3. Copy the ID and reply to our email
4. You'll receive an activation key within 24 hours — paste it into Activation key and click Activate

The Trial gives full functionality without restrictions for 30 days:

• All binding types (saddle stitch, perfect bound, folding)
• Watermark-free export, no sheet limit
• PDF/X-4 conversion with ICC profiles
• Batch CLI mode
• All templates and custom layouts

After 30 days the app still launches but export is locked until you load a production license key.

Standard licenses are bound to a hardware hash of one computer (motherboard serial, system disk, hostname). Moving to another computer requires a fresh activation.

Replacing a motherboard, CPU, or reinstalling the OS may require re-activation. Don't worry — just contact us and we'll re-issue a key within a day.

We offer three durations — all with full feature set:

• 6-month — €39 — perfect for one-off projects and seasonal volume
• Annual — €69 — best value, beats two 6-month renewals
• Perpetual — €139 — lifetime, one-time payment, 12 months of updates included

Full pricing: impressstudio.pl/en/#pricing

Yes. For 3+ seats we offer volume discounts and managed deployment (multi-seat or floating keys). Contact us for a tailored offer; we also provide priority support for larger print shops.

The perpetual license itself never expires. After 12 months only the right to free updates ends. You can keep using your current version indefinitely, or extend the update window for a small annual fee.

Export is locked at end of period — the app still launches and lets you preview templates and files. Order a renewal, paste the new key, and you're back to full functionality. All custom templates, settings and history are preserved.

1. Open the Template manager and click New
2. Name: A5 booklet — saddle stitch
3. Binding: Saddle stitch
4. Sheet size: SRA3 (320×450 mm)
5. Trim: A5 (148×210 mm)
6. N-Up: 2×1
7. Pages per signature: 8 (or 16 for longer pubs)
8. Bleed: 3 mm, safe zone: 5 mm, gutter: 5 mm
9. Marks: crop, registration, color bars
10. Save the template

Saddle stitch — for ≤60 pages: brochures, catalogs, folders. Cheaper, faster, but needs creep compensation.

Perfect bound — for thicker pubs (50+ pages): books, magazines. Has a spine, looks more premium, but each signature prints separately.

Rule of thumb: ≤48 pages → saddle stitch; 64+ pages → perfect bound; 48–64 pages → judge case by case (paper weight, esthetics, durability).

Page count must be divisible by 4 (one sheet = 4 pages of print). Templates typically use 8 or 16 pages per signature, so the count must also be a multiple of that.

If your document has e.g. 31 pages, pad to 32 with a blank page or trim to 28. imPRESS Studio adds blanks automatically when needed, but you'll have more control if it's done in the source PDF.

Yes — version 1.2 adds RollFed binding dedicated to sticker / label workflows. Setup:

1. In the template editor pick Binding type → RollFed. The Roll section appears: repeat count (variable repeat), gap X/Y between items, max segment length, optional auto-rotation
2. Sheet width = roll width (e.g. 320mm). Segment height is computed automatically
3. In Cutter marks section pick SummaOPOS or SummaOPOS-XY. The app draws four solid-black squares (default 3mm) at the cut group corners with default 5mm offset — Summa's optical sensor reads them and calibrates the cut path
4. Optionally in the Overlay / Logo section add your logo (PNG/JPG/PDF) — it gets stamped on every output sheet
5. Export PDF and send to your latex / solvent printer. After printing, the Summa cutter contour-cuts each sticker

Workflow tested with Summa OPOS XY. For other plotters (Mimaki, Roland) reach out via the contact form — we'll add a preset.

N-Up = number of publication pages per sheet side. X×Y = X horizontal × Y vertical.

• 1×1 — one page per sheet (proof print)
• 2×1 — classic booklet: A5 on SRA3, A4 on B2
• 2×2 — 4 pages per sheet: A6 on SRA3, A5 on B2
• 4×2 — 8 per sheet: business cards, labels

Pick based on trim size vs press sheet. imPRESS Studio auto-validates that the N-Up fits on the sheet given bleeds and margins.

Yes. Add files to the left panel (+ Add files… or drag & drop), check the ones to merge, click Load selected. They'll be combined in list order — change order with the ▲▼ arrows.

PDF/X-4 (ISO 15930-7) guarantees predictability on press — embedded fonts, defined color profiles, supported transparency and layers.

Most print shops require PDF/X-4 or PDF/X-1a. Files without this conversion may be rejected or flagged in preflight.

1. Download from ghostscript.com/releases/gsdnld.html
2. Pick the Ghostscript AGPL Release, file gs*w64.exe for 64-bit
3. Install in the default location (C:\Program Files\gs\gs[version]\)
4. Optionally add to PATH so imPRESS Studio finds it automatically
5. Or specify the path to gswin64c.exe manually in export options

Ask your print shop — they usually have recommendations. Common choices:

• Offset, glossy coated: ISOcoated_v2_eci, FOGRA39L
• Offset, uncoated: PSO_Uncoated_ISO12647_eci, FOGRA47L
• Digital print: sRGB IEC61966-2.1
• Newspapers: ISOnewspaper26v4, WAN-IFRAnewspaper26v5

Standard profiles ship in the icc/ folder. You can also point to your own profile in export options.

In Export options → Sheet range use:

• 1-5 — sheets 1 through 5
• 2,4,6 — single sheets
• 1,3-7,10 — combination
• empty — all sheets

Useful for first-sheet test prints or reprinting a specific page.

Try in order:

• Disable PDF/X-4 — Ghostscript conversion is the heaviest stage
• Check source size — high-res images and transparency slow things down
• Export a smaller sheet range
• Close other apps — imposition is CPU-intensive
• Use CLI mode in an overnight batch script

Check file status in Info (left panel). Common causes:

• Encrypted PDF — remove protection in Acrobat or another tool
• Unembedded fonts — Acrobat → Preflight → "Embed all fonts"
• Corrupted PDF — open in Acrobat and re-save

Verify that:

• The output file isn't open in Acrobat, a browser or another program
• You have write permission for the chosen folder (don't write to C:\Program Files\ without UAC)
• Antivirus isn't blocking the app — add the imPRESS Studio folder to exclusions

Email impress_studio@proton.me with:

• Description of the problem or suggestion
• App version (About)
• Windows version
• For bugs — log file from the app's logs/ folder
• (Optional) the PDF or template that triggers the issue

Reports are handled within 24 hours on business days.

Yes. Full batch imposition:

"imPRESS Studio.exe" impose --source in.pdf --output out.pdf --template tpl.json --pdfx4

Exit code 0 = success, 1/2 = error (check logs).

Yes — a template is a regular JSON file you can generate from a script. Export one template from the GUI as a reference, modify the fields (name, size, N-Up, margins, marks) and save as a new file. The CLI accepts it as-is.

A hot folder is a directory monitored by the application — when an operator drops a PDF into it, imPRESS Studio detects the new file, applies the chosen imposition template, and writes the imposed sheet to the output folder. The original moves to an archive folder (or is deleted, configurably), failed files go to an error folder. Available since version 1.1, configurable from the Tools → Hot Folders menu.

No limit — each with its own template, input/output folder and configuration. Typical setup: one for A5 booklets, one for gang-run business cards, one for covers. Each runner is isolated — a fault on one hot folder does not stop the others. A process-wide Ghostscript ceiling protects the machine from overload.

Yes. The application uses two parallel detection sources: FileSystemWatcher (push, low latency) and polling (pull, snapshot diff every N seconds). Polling is the safety net for SMB/DFS shares where FSW is known to drop events. A multi-stage stability probe also handles the case where copying a 200 MB PDF over the network is still in progress while Windows already raised Created.

Nothing is lost. Every job is "reserved" in a local SQLite ledger before the file is moved. After a crash, on next start, the runner recovers orphan reservations — files in the work folder return to input and are reprocessed. The UI shows a blue banner "Recovered N interrupted jobs", so the operator sees what happened.

No. The application computes a fingerprint for each file (SHA-256 of the first 1 MB + size + mtime). If a file with the same fingerprint was already processed successfully, subsequent drops are skipped. Re-export of the same PDF after editing produces a different fingerprint, so it is treated as a new job.

In GUI mode the hot folder host lives with the application process — closing the window also stops the host. For 24/7 operation, run the daemon from the command line: "imPRESS Studio.exe" hotfolder run (Ctrl+C stops it). This is the natural step before a full Windows Service version, planned for upcoming releases.

Yes — the host refuses to start runners when the license is invalid or expired. The manager UI shows a red banner with a link to the activation window in that case. The license is re-validated periodically (every 60 minutes) and once more before each export, so expiry mid-shift stops runners with a clear message instead of silently producing invalid sheets.
