Two booklets on every sheet

Two different jobs on one sheet
Two shops' A4 flyers share one SRA3 sheet, 1 up each. Drop the second file onto the sheet; each back prints right behind its own front.A4 2-up, different jobs
Say it in words
Type the order the way the customer said it, “job 1 DL 3up, job 2 10up, bleed 3”, and the sheet lays out 3 DL flyers and 10 business cards by itself, front and back.Read on your computer, no internet
Running numbers
Raffle tickets, 20 to an SRA3 sheet, numbered 0001 to 0100. Drag the number onto the ticket; cut and stack, and the numbers run in order, stub and ticket matching.20 per sheet · 5 sheets · 20 stacks

Bleed the file didn't have
An A5 flyer sent at its finished size: click Mirror the edge and DayZu adds 3 mm of bleed, lays it on SRA3 and exports with crop marks. No going back to the customer, and the original is never touched.Mirrored 3 mm bleed
AI makes a soft picture sharp
A small picture prints at only 118 ppi on A5. One click and the AI on your own computer enlarges it 2× (235 ppi). Compare before and after at 400%, then use it. Nothing is uploaded.2× enlarge, on your computer

What it does
The jobs a print shop does every day, worked out for you
Every number comes from DayZu's own calculation, and every job is built as a real PDF you see before you export. What you see on screen is what prints.
Fills the sheet for you
Tries every arrangement, turned and upright, and keeps the one that fits the most. Placed at 100%, with crop marks around the sheet.90 × 55 cards on SRA3: 21 up
Front and back, heads the right way
See both sides together before you print. The back is laid out in mirror position, so nobody has to remember to flip on the long edge for every job.
Saddle-stitched booklets
Drop in one file per page. DayZu orders the spreads for folding, lets you drag pages around, and adds creep for thick stock, by shifting or by scaling.
Adds the bleed that isn't there
Frame the good part of the artwork, pick the finished size (DL, 90 × 55, anything) and DayZu mirrors the edge out into bleed. The original is never touched.
Finds the cards in a proof
A customer sends one picture with the front and the back on it. DayZu finds both cards, splits them into front and back, and adds the bleed.
Sharpens soft images
Artwork designed with AI tools is often not sharp enough to print. Enlarge it 2× inside DayZu and compare before and after first. Nothing is uploaded.
How it works
Three steps from customer file to press
Drop your files
PDFs or pictures, one or many. DayZu reads the real size from the file; it never guesses the finished size.
Check the real proof
It fills the sheet at once and builds a real PDF of both sides, with a list of anything to check before printing.
Export, ready to print
A sheet-size PDF that has passed a full check, straight to your printer. Your original file stays as it was.
Privacy
Customer work stays in your shop
DayZu runs on your shop's computer, not on someone else's server. Files and pictures go nowhere. It goes online only to check for a new version, when you write to us in the chat, and, if you connect your shop to the DayZu Hub, to send job cards, never files.
- No uploadsLayout, file checks and AI enlarging all run on your computer, even with no internet.
- Originals left aloneNo recompressing, no downsampling, no silent colour changes. Everything DayZu does is recorded in the output file.
- Checked before every exportThe proof on screen is drawn from the PDF you will print, and export only unlocks once that file passes a full check.
Details
Works with the printer you already have
DayZu exports standard PDF, so any digital press or RIP that takes PDF will do. It prints real jobs every day on a Fuji Xerox digital press.

Questions
Before you try it
Does it need the internet?
No. Everything runs on your computer; it only goes online to check for a new version. Shops that don't allow internet access still get every feature.
Do our customers' files go anywhere?
No. Files, file names and pictures stay on your shop's computer. Even AI enlarging runs there.
Does it run on a Mac?
A Mac version is on its way for the beta. Tell us which computer your shop uses, so we can get it to you first.
How is it different from InDesign or Kodak Preps?
DayZu does one job: getting files ready to print, fast, for the everyday work of small and mid-sized print shops — business cards, flyers, menus and saddle-stitched booklets. Little to set up, and in your language.
Is the beta free?
Yes, free for the whole beta. We'll tell beta shops well before we start charging.
What if a job prints wrong?
During the beta, check the front and back proofs in DayZu and print one test sheet before every long run. If something is wrong, send us a screenshot and we'll fix it fast.
