What Not to Do When Laminating a Printed Calendar

Laminating a calendar turns a paper sheet into something you can wipe clean and reuse. Done right, it lasts for years. Done wrong, you get bubbles, a smeared month, or a warped page that won't lie flat.

Most laminating problems are easy to dodge once you know them. Here's what to avoid so your calendar comes out crisp and flat.

Don't laminate ink that's still wet

Fresh prints need a little time. Inkjet ink especially can stay slightly damp for a few minutes, and the heat of a laminator will smear or blotch it. Give a home print at least ten to fifteen minutes to dry, and longer for pages with heavy color.

Laser prints and prints from a copy shop dry almost instantly, so they're safe to run right away. If you're printing at home, our printing guide covers settings that lay down cleaner ink in the first place.

Don't cut off the border

It's tempting to trim your calendar right to the edge before laminating. Don't. The pouch needs a small margin of clear plastic around the paper to seal shut. Cut to the very edge and the laminate can peel or let moisture creep in.

Leave at least a few millimeters of space around the page, and trim the plastic, not the paper, after it comes out. A design with built-in margins makes this easy. Many of the ready templates already leave that room around the grid.

Don't grab the wrong pouch

Laminating pouches come in different thicknesses, measured in mil. A common mistake is using a pouch your machine can't handle, which leads to jams or a cloudy, half-sealed finish.

• 3 mil is thin and flexible, fine for pages you'll swap out often.
• 5 mil is sturdier and lies flatter, a good match for a wall calendar.
• Check your laminator's limit before you buy. Cheaper machines often top out at 5 mil.

Match the pouch to the page size too. A Letter page needs a Letter pouch, with that sealing margin included.

Don't rush it through

Speed is the enemy of a clean laminate. Feeding a second page before the first is done, or tugging the sheet as it comes out, causes wrinkles and bubbles. Let the machine pull the pouch through on its own.

Feed the sealed edge in first so air can escape out the open end. Then let it cool on a flat surface. Warm laminate is soft and curls if you bend it or stand it up too soon.

Don't laminate what you might change

Laminating is permanent. Once a page is sealed in plastic, you can't reprint it or fix a typo, so it's worth one more look before you feed it in. Check that the year is right, the dates line up, and any names or events are spelled the way you want.

Because it's permanent, laminating suits calendars you plan to reuse, not ones tied to a single month you'll toss. A perpetual layout, an undated chore chart, or a meal-planner grid all make sense laminated, because you write on them with a dry-erase marker and wipe them clean. A dated month for this year is usually better left as plain paper you can recycle when it's done.

If you do want a dated calendar laminated, pick one you'll want on the wall for the whole run, like a full-year sheet. And test your marker first. Some permanent markers won't wipe off laminate, while dry-erase and wet-erase pens come clean with a cloth. A quick scribble in the corner tells you which one you've got before you write across the whole month.

Laminate your calendar so it lasts

Get these few things right, dry ink, a paper border, the right pouch, and a slow pass, and your laminated calendar comes out flat, clear, and ready to wipe clean all year. That's a sheet you print once and use for months, instead of running off a new one every few weeks.

A reusable calendar pairs well with a dry-erase marker, so pick a layout with roomy boxes first. Build one in the calendar maker or grab a monthly calendar, print the version you want to keep, and seal it once for a calendar that holds up to a whole year of daily use.
