Overview

If "Caution Laser Beam" needs saying clearly, this is the sign, and caution laser beam sign printing is what we do. It warns that a laser beam is in use, and you will find it in entertainment venues, cutting rooms, workshops and laboratories.

Caution laser beam sign printing: which material

Our caution laser beam sign printing comes on three kinds of board:

  • 3mm Foamex, a rigid PVC foam board that screws or sticks up easily and is happiest indoors or out for a season
  • 3mm Dibond, aluminium skins on a solid core, the one to pick for a sign that stays outside for years
  • self-adhesive vinyl, which sticks flat to smooth walls, doors, glass and machine guards

Inside, Foamex or vinyl does the job. Outside for the long haul, go Dibond.

Reading the sign

It reads "Caution Laser Beam". Yellow triangle, black border: the shape everyone reads as "watch out". The layout is a yellow triangle above black wording, plus the ISO 7010 W004 symbol (laser beam). The CAUTION heading tells people to watch out; the line beneath says for what.

Putting it up

At the entrance to the laser area. Give people time to react: the sign should come before the hazard, not after it.

Before you order caution laser beam sign printing, think about how far away people will be. Rule of thumb from ISO 3864-1: each 25 mm on the short side of the sign gives roughly a metre of reading distance. That makes A4 to about 8 m, A3 to about 12 m, A2 to about 17 m and A1 to about 24 m. Pick bigger for car parks, yards and long runs of corridor.

A warning sign sits alongside your risk assessment and other controls; it does not replace them.

Under the Health and Safety (Safety Signs and Signals) Regulations 1996, employers put up a safety sign wherever a risk is still there after other controls. Warning signs take the yellow triangle with a black edge.

Send a print-ready PDF, build it in the online designer, or pay for our artwork service (you get 1 design and 2 rounds of changes). Whichever you pick, a person checks the file before it prints. Each caution laser beam sign printing job is printed to order and sent out from the UK. Delivery to a UK mainland address is £7.95, or free once the order passes £100 after any discount (artwork fees are not counted). The Highlands add £10, and addresses in Northern Ireland, the Scottish islands, the Isle of Man, the Channel Islands, Scilly or the Isle of Wight get a quote. Full details are on the delivery page.

Which size do I need?

A safety sign must be large enough to read from where people will see it. Our conservative guide, based on the distance-factor method in ISO 3864-1, is about 1 metre of viewing distance for every 25 mm of sign height (the shorter side). Use it with your own risk assessment.

SizeReadable from up to about
A4 (210 × 297 mm)8 m
A3 (297 × 420 mm)12 m
A2 (420 × 594 mm)17 m
A1 (594 × 841 mm)24 m

Well lit or internally lit signs can be read from further away; dim areas need larger signs.

Questions

Quick answers about caution laser beam sign printing.

How big should the Caution Laser Beam sign be?

Think about the furthest point someone needs to read it from. For "Caution Laser Beam", A4 (210 × 297 mm) for readers up to 8 m away, A3 (297 × 420 mm) for readers up to 12 m away, A2 (420 × 594 mm) for readers up to 17 m away and A1 (594 × 841 mm) for readers up to 24 m away. Those distances assume ordinary light, so if it is gloomy or people are driving past, step up one size.

Is the symbol on this sign an ISO 7010 one?

Yes: W004, Laser beam. The "Caution Laser Beam" text sits alongside it, and the pictogram is taken from public domain artwork.

Where is the best place to put the "Caution Laser Beam" sign?

Put it at the entrance to the laser area. Fix it where it will not be hidden by doors, deliveries or vehicles.

Am I legally required to display "Caution Laser Beam"?

The Health and Safety (Safety Signs and Signals) Regulations 1996 say employers must put up a safety sign when a risk remains that other measures cannot remove. A warning uses the yellow triangle with a black border. Your risk assessment is what decides the exact positions.

Can I buy more than one Caution Laser Beam sign?

Yes, change the quantity before you check out; every sign is made to order. Need a big mix of different signs for a school, club or site? Use the Get a quote page. Goods worth £100 or more travel free to a UK mainland address; below that, delivery is a flat £7.95 for the whole order.

Is anything added to the price of the "Caution Laser Beam" sign at checkout?

Only delivery, where it applies. The price you see is the price you pay at checkout. The £5.02 starting price for the "Caution Laser Beam" sign is the full price of the goods. Goods worth £100 or more travel free to a UK mainland address; below that, delivery is a flat £7.95 for the whole order.

Asked by buyers

How much will the Caution Laser Beam Sign set me back?

£5.02 is where the Caution Laser Beam Sign starts, set up as A4 (210 × 297 mm) and self-adhesive vinyl on the Saver speed. Change the size, material, extras, quantity or speed and the total on the page moves straight away. The price you see is the price you pay at checkout, with delivery the only thing that can be added. Delivery anywhere on the UK mainland is £7.95 an order, and it costs nothing once the goods come to £100 or more after any discount code (design and artwork fees are not counted).

Is delivery ever free?

It is £7.95 for the whole order, not per item, and free once the goods reach £100 after any discount code; design or artwork charges are left out of that £100. On its own the opening price of £5.02 would add £7.95 for mainland delivery; reach £100 of goods and that goes to zero. A mainland Highlands postcode puts a single £10 on the order. Northern Ireland has its delivery priced before you pay, and so do the Channel Islands, the Scottish islands, Scilly, the Isle of Wight and the Isle of Man. Before delivery, this sign costs from £5.02. On this page, Caution Laser Beam Sign starts from £5.02.

If I buy the Caution Laser Beam Sign today, when will it leave you?

As the page first opens, the speeds for the Caution Laser Beam Sign are Express 2 working days, Standard 4 and Saver 6, counting Monday to Friday and skipping bank holidays. The count begins once we have your order and a file ready to print. A bigger size or a different material can move it by a day either way; each speed shows its own days as you choose. Tracking arrives by email on the day it ships, and the courier usually takes one to three working days from there.

How big does our Caution Laser Beam Sign have to be to read across a room or yard?

Stand where someone first needs to read "Caution Laser Beam" and pace out the gap to where it will hang. Then match that number: up to 8 m for A4, 12 m for A3, 17 m for A2 or 24 m for A1. Dim corners or people on the move call for one size bigger. Those distances follow the ISO 3864-1 distance-factor method (25 mm of height per metre) and sit alongside your risk assessment, not in place of it. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all.

Which sizes can the Caution Laser Beam Sign be printed in?

Smallest: A4 (210 × 297 mm), from £5.02. Biggest: A1 (594 × 841 mm), from £15.12. 2 more are listed in between, each priced on the cheapest options. Not sure which? Mark the space out with tape or string first and stand back to look. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. For reference, Caution Laser Beam Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).

What will people understand when they see a Caution Laser Beam Sign?

Its job is to flag up a hazard: "Caution Laser Beam" is laid out as a warning sign, built around a black-edged yellow triangle. The picture is W004 from ISO 7010 (laser beam), which gets the point across to visitors who read little or no English. Those colours and shapes come from the 1996 Safety Signs and Signals Regulations, which is why they look familiar.

How much does an A2 (420 × 594 mm) sign cost?

From £9.33, with the cheapest settings and the Saver service. Material by material, it is 3mm Foamex at £42.91, 3mm Dibond aluminium composite at £61.17 and self-adhesive vinyl at £9.33. Add £7.95 for UK mainland delivery, or nothing at all once the goods reach £100. Select it on the page and swap materials, finishes and speed to watch how the figure moves. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. For reference, Caution Laser Beam Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).

We are kitting out a hall with several different signs. Can they all go in one order?

Yes. Put each sign in the basket with whichever size and board suits its spot, then pay once at checkout. One delivery charge covers the whole order, and it drops to nothing when the goods reach £100 after any discount code. Picking the same board for every sign gives the set a matching look; "Caution Laser Beam" comes in A4, A3, A2 and A1. Before delivery, this sign costs from £5.02.

Can a private person buy a single sign?

Yes. One is enough, and you do not need a business name or an account to check out. The opening price is £5.02, and any bank card will do. On its own the opening price of £5.02 would add £7.95 for mainland delivery; reach £100 of goods and that goes to zero. A person still checks your file before it is printed, just as for a big order. Before delivery, this sign costs from £5.02. On this page, Caution Laser Beam Sign starts from £5.02.

How much for the biggest size, A1 (594 × 841 mm)?

From £15.12, with the cheapest settings and the Saver service. Material by material, it is 3mm Foamex at £63.13, 3mm Dibond aluminium composite at £88.40 and self-adhesive vinyl at £15.12.

I live in the Scottish Highlands. Will the Caution Laser Beam Sign cost more to send?

The whole UK is covered. Outside it, sadly, we cannot deliver. Mainland addresses in the Highlands pay one extra £10 on the order, even when delivery would otherwise be free. For Northern Ireland, and for the Channel Islands, the Scottish islands, Scilly, the Isle of Wight and the Isle of Man, we tell you the delivery cost before you pay, so message us your postcode on the Contact page or our Get a quote page. Choose Saver and this sign leaves us after 6 working days; Express brings that down to 2. Before delivery, this sign costs from £5.02. On this page, Caution Laser Beam Sign starts from £5.02.

Is there a quicker turnaround for this sign?

Work back from the day you need it. Express takes 2 working days to get the Caution Laser Beam Sign out, against 6 on Saver, and costs £6.68 on the opening option rather than £5.02. Add up to three working days for the courier, plus any time you need to finish the file. Cutting it fine? Put your date in the question box before you order.

How many pixels does a photo need to print well on this sign?

Roughly 7,016 pixels across and 9,933 down for an A1 (594 × 841 mm) design, which is 300 dpi. Things read at arm's length need that 300 dpi at full size to stay crisp. Text and logos are safest as vector art, which never goes fuzzy. Pictures saved from a website or social media are nearly always too small, and our file check will point out any that could print blurred. Make the artwork for this sign the same size as the one you order, such as A4 (210 × 297 mm). Material choices for Caution Laser Beam Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

Can the wording on a Caution Laser Beam Sign be changed, or our logo added?

A school can add its crest to "Caution Laser Beam", a club its badge, a shop its name. Choose typesetting (£15) if you know the words, or design from your brief (£35) if you would like us to lay it out; each comes with one first draft and two rounds of changes. Have your own finished file? Upload it free and one of our team will look it over. Keep the symbol and safety colours unchanged so the sign still reads the right way. Make the artwork for this sign the same size as the one you order, such as A4 (210 × 297 mm).

Will anyone look at my file before it is printed?

Every file gets a human check for size, bleed and resolution, and we contact you about any problem before printing. Nobody can know your details better than you, so double-check names, numbers and dates: we print what is supplied, and work begins once the order and file are confirmed. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On its opening option, Caution Laser Beam Sign leaves us after 6 working days on Saver.

Does the Caution Laser Beam Sign come in a peel-and-stick version?

Yes: self-adhesive vinyl is one of the material choices, and that version is simply a sticker with a backing to peel off. Use it on smooth things like glass, doors, cupboards, machines or painted plaster. Clean and dry the surface first, then smooth it on working out from the middle. If the wall is rough or dusty the sticker will not grip well, so go for one of the boards. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On this page, Caution Laser Beam Sign starts from £5.02.

What thickness is the Caution Laser Beam Sign, and does it feel sturdy?

The sticker version, in self-adhesive vinyl, is only a film, so it sits flush on a door or wall. Every rigid option measures 3 mm. Foamex is a lightweight PVC foam board. Dibond has aluminium on both faces around a plastic middle, so it stays flat and firm but is easy to fix. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On its opening option, Caution Laser Beam Sign leaves us after 6 working days on Saver.

We are putting up a full set of signs at our premises. Which ones sit well next to this one?

Two good companions for it are Caution Pinch Point Sign and Warning Very Hot Water Sign. Each has a page of its own with every size, material and a live price, and picking one material for all of them makes the wall look like a matching set. Put the lot in a single basket and you pay one delivery charge, which drops to nothing when the goods reach £100. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.

Will a Caution Laser Beam Sign cope with rain and wind outdoors?

"Caution Laser Beam" can go outside as long as you match the material to the job. For a sign that stays out for years, Dibond is the one to choose. Foamex will manage a sheltered spot, such as a porch or under a canopy, but it is really an indoor board. Strong sun slowly fades any print, so glance at outdoor signs every so often and swap any that have become hard to read. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.

What is the easiest way to put up a Caution Laser Beam Sign?

It depends what "Caution Laser Beam" is going on. Brick or plaster: screws through holes near the corners, washers under the heads, and a light hand (Foamex especially). Painted doors and smooth walls inside: foam tape or sticky pads, no drilling needed. Fences and railings: two or four holes, then cable ties. Glass and glossy panels: the vinyl version, pressed on after a wipe and a dry. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.

Which material is cheapest for the Caution Laser Beam Sign?

Taking the smallest size, A4 (210 × 297 mm), as the example: self-adhesive vinyl at £5.02, 3mm Dibond aluminium composite at £40.79 and 3mm Foamex at £27.79. Larger sizes follow a similar pattern, and the full grid sits in the size table further up the page. Think about where it is going first: a cheap material in the wrong spot can end up costing more. Before delivery, this sign costs from £5.02. Material choices for Caution Laser Beam Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

Do we legally have to display a Caution Laser Beam Sign?

Not in every case. The Health and Safety (Safety Signs and Signals) Regulations 1996 require employers to put up safety signs where a risk is left over once other controls are in place. So whether you need "Caution Laser Beam" on display, and where it goes, comes out of your own risk assessment. A sign adds to other safety measures and never takes their place. The symbol on this sign follows ISO 7010, reference W004.

Which cards do you take, and is paying online safe?

You pay by debit or credit card when you check out, and you can do it as a guest without making an account. Card details are handled by Stripe, a specialist payment company, so the full card number never reaches us or sits on our system. Printing starts after payment goes through and your file has been checked. If your group needs a price agreed before anyone pays, ask for a quote instead. Before delivery, this sign costs from £5.02. Nothing is printed ahead of time: each sign is made to order for you. Material choices for Caution Laser Beam Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

Can a volunteer order without setting up an account?

Yes. There is a guest checkout, so a one-off order does not need a login. Payment is by debit or credit card, processed by Stripe. The confirmation email that follows lists everything bought and what was paid, which helps when you claim the money back from the group. What the page shows is what the group pays, plus any delivery. Nothing is printed ahead of time: each sign is made to order for you. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On its opening option, Caution Laser Beam Sign leaves us after 6 working days on Saver.

Next year we will want the same sign again. Is reordering easy?

Yes. Treat it as a fresh order of the same item with the same settings, and attach the file you used last time. Keep a copy of the print file in a shared folder so whoever orders next year can find it. Change any details that have moved on, such as a new email address or this year's date, before uploading. Nothing is printed ahead of time: each sign is made to order for you. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On this page, Caution Laser Beam Sign starts from £5.02.

We need a few different designs. Do they each need their own order?

One checkout covers the lot. Add a basket line for every design, attach the right file to each, then pay once. You pay a single delivery charge of £7.95 for the whole order, or nothing if the goods add up to £100 or more. Repeating one design on another line? Choose the artwork choice that points to a file already in the basket, and no second design fee is charged. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. Nothing is printed ahead of time: each sign is made to order for you. On its opening option, Caution Laser Beam Sign leaves us after 6 working days on Saver.

Our club needs a big batch of signs, or an odd size. Can you price it?

Our Get a quote page is the place, and it also handles delivery to Northern Ireland and the islands. For anything the page cannot do, tell us the size, number, material, date and postcode on Get a quote, add a file if you have one, and we email a price back.

Our treasurer needs a receipt for the accounts. What do we get?

Every order gets a confirmation email listing what was bought, the options chosen and the amount paid, and a club, school or small firm can file that as its record of payment. What you pay for this sign is the price shown on the page plus any delivery charge, nothing more. If your accounts need a particular kind of invoice, ask through the Contact page before you order and we will tell you what we can provide. Nothing is printed ahead of time: each sign is made to order for you. Before delivery, this sign costs from £5.02. For reference, Caution Laser Beam Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).

I am not sure which options to pick for this sign. Can someone advise me?

Of course. Tell us three things: where this sign will go, whether it is for one day or for years, and your deadline. Send that through the question box on this page or the Contact page, and a member of the team will suggest options. If what you need is outside the options listed, the Get a quote page lets you describe it and get a price. Nothing is printed ahead of time: each sign is made to order for you.

Do I have to register before I can buy?

No. Guest checkout is fine, and card payments go through Stripe, so a debit card or a credit card both work. If you choose to open an account while checking out, My Account keeps your past orders.

Can I send this sign back if I no longer need it?

Not for a change of mind. This sign is made for your order, and goods made to your specification fall outside the 14-day cancellation right (reg. 28(1)(b) of the Consumer Contracts Regulations 2013). You can still cancel and get all your money back before production begins. Anything faulty, damaged or wrong is covered by the Consumer Rights Act 2015, and we reprint it or refund you.

Can I swap my file once I have paid?

It depends on timing. Until production begins, a new file can replace the old one, or the order can be cancelled with a full refund; once it has begun, nothing can be changed. Message us straight away on the Contact page with your order number. Items printed exactly as supplied or designed do not count as faulty, so check names, numbers and dates first.

Who looks after me once I have bought the Caution Laser Beam Sign?

You deal with FatPrint the whole way through. Once you order, somebody checks the artwork, the Caution Laser Beam Sign is printed specially for your order, and a courier delivers it with a tracking link by email. Need to ask something along the way? Use the question box here or the Contact page and a real person answers.

Will my logo colours come out the same as on screen?

Very close, but not always identical. A screen glows, print reflects light, so a small difference is normal. Sending CMYK artwork keeps it nearest; RGB is changed to CMYK before printing and the brightest greens, blues and oranges can look a touch flatter. For an exact brand colour, give us the Pantone reference and we get as close as the material allows. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On its opening option, Caution Laser Beam Sign leaves us after 6 working days on Saver.

I have never ordered printing before. Do I need to know the technical words?

No. A person on our team checks every file for size, bleed and resolution and tells you in plain words if anything needs changing. Or pick typesetting for £15 and we lay out your words and logo for you, with a first draft and two rounds of changes. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Make the artwork for this sign the same size as the one you order, such as A4 (210 × 297 mm). Material choices for Caution Laser Beam Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

Some of our visitors have poor eyesight. Will this sign be easy for them to read?

Good contrast, a simple bold typeface and the right size for the reading distance make the biggest difference. Our standard safety designs already use the high-contrast colour combinations set out for safety signs. Put it at eye level in good light, away from reflections, and use as few words as possible. Make the artwork for this sign the same size as the one you order, such as A4 (210 × 297 mm). Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On its opening option, Caution Laser Beam Sign leaves us after 6 working days on Saver.

What if A1 (594 × 841 mm) is still too small for the Caution Laser Beam Sign?

The size list tops out at A1 (594 × 841 mm), starting at £15.12. Anything bigger is priced on request: send the size, the material and how many through our quote form. A board over A0 counts as oversize for delivery, which adds £15 to the order once. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. Material choices for Caution Laser Beam Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

Does a Caution Laser Beam Sign come upright or wide?

Portrait. "Caution Laser Beam" is offered in A4, A3, A2 and A1. That shape is made for doors, posts and slim wall spaces. If your spot needs the opposite, pick one of the paid design options and we re-lay it to suit. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all.

The spot gets full sun all afternoon. Could this sign warp in the heat?

It depends on the board. Foamex is foamed plastic, and a large, thin sheet in strong sun can curve, most of all when it is held only at the corners. Dibond sandwiches a core between aluminium skins and stays flat, which is why people choose it for signs that live outdoors for years. If you go with Foamex, fix it flat to a wall along its length or pick a thicker option. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Nothing is printed ahead of time: each sign is made to order for you. Material choices for Caution Laser Beam Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

Could the Caution Laser Beam Sign go on a door, say an office or classroom door?

It can, and the vinyl sticker version is the tidiest way to do it on a door or a glass panel. On a flat door, the 3mm Foamex board with foam tape on the back is a good alternative. Aim for eye height, either beside the door or on the side people push, so an open door does not hide it.

Material choices for Caution Laser Beam Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.
