Setting Up Your First Photo Magnet Template

A step-by-step guide to measuring your graphic punch, setting up a magnet template, test printing, and calibrating printer compensation for perfect magnets every time.

Getting your template dialed in is the foundation of a smooth event workflow. This walkthrough covers everything from measuring your punch to calibrating your printer so every magnet comes out crisp and perfectly sized. We'll use a 63.5 × 63.5 mm (2.5 × 2.5 in) square magnet as our working example throughout — the same principles apply to any size or shape you use.

Best completed on a desktop or laptop — you'll need access to your printer settings and the Fridge Candy template editor.

What You'll Need

  • Your graphic punch
  • A ruler (millimetres preferred — more precise than inches)
  • A printer that supports borderless printing
  • A sheet of photo paper (plain paper works fine for test prints)
  • A computer with access to Fridge Candy

1 Measure Your Punch

Punch a blank sheet of paper and measure the cutout from edge to edge with your ruler. Write that number down — it's your punch size. For this guide we'll use 84 mm as the example.

Tip: Stick to millimetres. A 1 mm error is far easier to catch and correct than trying to work in fractions of an inch.

Note: most "square" punches actually clip the corners at 45°, creating a slight octagon. Measure the flat edges, not corner to corner. If your punch is rectangular, measure both width and height separately.

2 Know Your Three Zones

Every template is built around three concentric areas:

ZoneWhat it is
Cut LineThe outer edge — matches your punch size (84 mm in our example)
BleedA buffer band that wraps around the edge to prevent white borders if the punch isn't perfectly centred
Image AreaThe visible face of the finished magnet — what your customer actually sees

With an 84 mm punch and 10.25 mm of bleed on each side, the visible image area works out to 63.5 mm (84 − 10.25 − 10.25).

3 Enter Your Dimensions

In the Fridge Candy template editor you enter two values: magnet size (the image area) and bleed per side. Calculate bleed like this:

bleed per side = (punch size − magnet size) ÷ 2

Using our example: (84 − 63.5) ÷ 2 = 10.25 mm

Enter 63.5 mm as the magnet size and 10.25 mm as the bleed. The system automatically applies that bleed to both sides — you only enter it once.

4 Print a Test Sheet

Before printing a full run, do a single test print. Set your printer to:

  • Paper size — match the sheet loaded (e.g. 4×6 or 5×7)
  • Borderless printing — on
  • Scaling — Actual Size / 100% / None (never "Fit to Page")
  • Expansion — No Expansion if available; Minimum Expansion as a fallback
Even with expansion set to none, many printers still scale borderless output up slightly. That's normal — the next step corrects for it.

5 Check the Alignment

Place your test print in the punch the way you normally would and check whether the cut lines line up:

ResultWhat it meansWhat to do
Perfect fitPrint matches the punch exactlyNo adjustment needed
Too bigPrinted area overshoots the punchApply negative compensation
Too smallPrinted area falls short of the punchApply positive compensation

Measure how many millimetres off it is — that number guides your compensation value.

6 Calibrate

Open Advanced Options in the template editor and enter a compensation value to scale the output up or down to match your specific printer's behaviour.

The loop is simple:

  1. Enter a compensation value
  2. Print another test sheet
  3. Measure against your punch
  4. Adjust if needed and repeat

Most printers only need one or two rounds and land somewhere between −2 mm and +2 mm. Once it's set, it stays consistent for that printer.
