Live test
Test your printer: does it scale?
A test sheet with a millimetre grid and a Jordanian 166 × 82 mm cheque frame. Print it from your browser and measure — or hold your cheque over it against the light. The difference you see is the same difference that ruins a cheque leaf.
- 1
Print the test sheet
A4 paper, actual size (100%), no margins. If your browser does not offer those options, print with the defaults — that is exactly what we want to measure.
- 2
Measure with a ruler… or with your cheque
Measure the reference line (should be 100 mm) and the distance from the paper edge to the corner (should be 10 mm). Or hold a blank cheque from your chequebook over the frame against the light: does it match, or does it drift?
- 3
Enter the measurements
We work out the scaling and offset, and how many millimetres the boxes would drift across the width of a cheque.
The test sheet
Sheet preview
This is what comes out of your printer. The grid is in real millimetres and the frame is the standard Jordanian cheque size.
Print at actual size (100%) on A4 with no margins. The top-left corner of the grid sits 10 mm from both paper edges. Both reference lines are exactly 100 mm. The frame below is the standard Jordanian cheque size, 166 × 82 mm: hold a blank cheque over it against the light.
Nothing is uploaded to any server. The sheet is generated inside your browser and goes straight to the printer.
Result
What did you get?
Enter the measurements in millimetres. We calculate the scaling, the offset, and how far the boxes drift across the width of a cheque.
Why does this happen?
The browser scales, and so does the printer
A web page passes through the browser’s scaling (“fit to page”, margins, headers) and then through the printer driver, which may substitute the paper size. Each layer shifts things by millimetres, and the result changes with every print dialog and every machine. On an A4 sheet you never notice. On a cheque 166 mm wide, 3% scaling is 5 mm outside the box.
- Sheek generates a PDF with millimetre coordinates and sends it to the printer with no scaling
- A calibration wizard using this same grid, once per printer — and the offset is saved
- A MICR guard: it never prints over the forbidden band
- The Jordanian cheque size, 166 × 82 mm, calibrated and confirmed
Questions
Before you print
I don’t have a ruler — how do I measure?
Use a blank cheque from your chequebook: hold it over the printed frame against the light. If all four edges line up, your printer and browser did not scale. If the frame is smaller or larger than the cheque, there is scaling. If it matches in size but is shifted, there is an offset.
The frame came out exactly right. So I don’t need the app?
It means this combination of browser, printer and settings is right today. Try another browser, or after an update, or from a colleague’s machine, or with “fit to page” — the number changes. Sheek fixes the result because it bypasses the browser layer entirely and saves each printer’s offset by name. Beyond scaling, there is the ledger, the amount in words, and maker–checker approval.
My browser did not offer “no margins” or “100%”
That is part of the problem: some browsers and printers impose margins or scaling without asking. Print with the defaults and measure — the offset you get is the one that happens on every cheque you print from the web.
Is any data uploaded?
No. The sheet is generated inside your browser, and the measurements you enter are calculated on your device and never sent anywhere.
