Flame Resistant Apparel Printing in Southern Utah

If you run a crew in Cedar City, St. George, or anywhere in Southern Utah and you want your logo on FR shirts, the decoration is the part that can undo what you paid for. At Pulse Merch we screen print and embroider workwear for local contractors, electricians, and plant crews, and FR jobs get a different intake conversation than a stack of cotton tees. This article covers what we ask before we touch an FR garment, when screen printing makes sense, when embroidery does, and where both go wrong.

You already know what FR clothing is for. The question is what happens to it once a logo goes on.

Start With the Garment’s User Guide, Not the Artwork

The first thing we want from you is the garment’s user information guide or the maker’s decoration instructions, not your logo file. Garment makers spell out what they allow on their own fabric, and that document outranks anything we or any decorator can tell you.

PIP’s FR user information guide is a good example of the typical position. It says that attaching non-flame-resistant or non-heat-resistant emblems may compromise safety and should be avoided where possible. If you do use one, it should be no larger than a credit card, you should not mark through certification markings, and you should not remove safety or cleaning labels. Other makers publish their own limits, and they are not all the same.

So the order of operations we recommend is:

Pick the garment for the hazard you have.
Read the maker’s decoration limits for that garment.
Then design the logo to fit inside those limits.

Most reprints on FR jobs come from doing it in the reverse order. Someone approves a big chest-and-back design on a tee, then finds out the garment they bought does not tolerate it.

Confirm the Hazard Before You Confirm the Shirt

We are a decorator, not a safety consultant, and we do not assess your hazards. But we see enough mismatches that it is worth saying: FR is not one thing. A shirt rated for flash fire is not automatically the right answer for an arc flash exposure, and the reverse is also true.

OSHA makes the point directly in its arc flash publication: FR or rubber-insulated PPE does not necessarily provide arc flash protection, and employers need to assess the hazard and choose PPE accordingly. NFPA 2112 is the standard for garments worn by industrial personnel facing short-duration flash fire exposure, with minimum design, performance, testing, and certification requirements. If your safety manager or insurer has told you which standard applies, tell us when you request the quote. It changes what we recommend.

This matters for decoration because the standard behind your garment is what defines how much non-FR material you can put on the outside of it. We would rather ask that question on the first call than explain a rejected shipment later.

Screen Printing on FR Fabric

Screen printing is the method most Southern Utah crews ask for, because it is fast on 24 or 48 pieces and holds up well on heavier workwear fabric. On FR garments it has a specific limitation: the ink is a layer sitting on top of the fabric, and ordinary plastisol or water-based ink is not itself flame resistant.

That is why the size of the print matters more here than anywhere else in our shop. A small left-chest logo is a different risk than a full back print. The research we rely on here is consistent on the principle. Customization is acceptable as long as it does not compromise the garment’s flame-resistant properties, and non-FR decoration should be kept minimal. Where makers give a number, as PIP does with the credit card limit, treat it as a hard ceiling, not a target.

What screen printing does well on FR work:

A one- or two-color left-chest logo, kept small and clean.
A small sleeve or collar-area mark where the maker allows it.
Simple name or crew-number prints that hold detail.

What we steer people away from:

Full back prints on FR shirts, especially in heavy ink coverage.
Large solid blocks of ink over seams or pocket edges.
Multi-color artwork with fine halftones, which crack first on a fabric that gets industrial-washed.

We cover the general behavior of ink on work garments in our practical guide to screen printing on workwear, and our page on FR shirt printing in Southern Utah goes through what holds up on the shirts themselves.

Embroidery on FR Garments: Where the Argument Is

Embroidery is the other obvious choice, and opinions differ. Some garment manufacturers publish guidance saying embroidery is the riskier option because needle holes break up the continuity of the fabric and could let flame through. Others allow it with conditions. We are not going to pretend there is one answer. The answer depends on the garment maker’s instructions for that exact garment.

What we can tell you from running embroidery machines is how the details play out:

Stitch count and density. A dense logo punches a lot of holes in a small area. A lighter, simplified logo does less to the fabric than a tightly packed one.
Thread. Standard polyester or rayon thread is not FR. OSHA notes that common nylon thread may reduce the protection of FR clothing when used in repairs. The same logic is why you should ask your garment maker whether it specifies an FR thread for decoration, and tell us so we can source it.
Backing and patches. Stabilizer sits behind the stitching. If the maker has a rule on backing, that rule needs to reach us before we hoop the garment.

If your garment maker says no direct embroidery, an alternative some crews use is a sew-on patch made from FR materials. Professional guidance from the British Safety Industry Federation lists embroidery, heat-applied logos, screen printing, and sew-on badges as methods in use, and recommends FR logos on garments certified to heat and flame standards. That is UK guidance, so treat it as a reference point for buyers, not as the US rule.

For how our embroidery process works generally, see how embroidery works on durable custom apparel.

Screen Printing or Embroidery: How We Decide

We get asked to just pick one. Here is how we sort it, once the garment maker’s rules are on the table.

Screen printing makes sense when:

The garment maker permits ink or heat-applied marks and you want a small, simple logo.
You are decorating a lighter FR knit, such as a polo or tee, where stitching can pucker the fabric.
The order is a few dozen shirts with a one- or two-color mark.

Embroidery makes sense when:

The maker allows stitching, and the logo is small and can be simplified.
The garment is a heavier jacket, coverall, or canvas-weight shirt that carries stitches without distorting.
You want a mark that will outlast many wash cycles without cracking or fading.

Neither makes sense when:

The maker says do not decorate. Some garments are sold as is, and the answer is to buy them without a logo and use a separate, non-FR layer or a hard hat or vest for identification.
The logo has to be large. Large and FR do not go together on the outside of a protective garment.

There is no universal winner. Fabric, garment type, logo size, and the maker’s instructions decide it, in that order.

Placement and Size: Keep It Small and Away From Labels

For FR work we put the logo in the least disruptive spot on the garment. That is usually the left chest, kept inside the size the maker allows, and nowhere near the labels. The PIP guidance is specific: do not mark through certification markings, and do not remove safety or care labels. Those labels are how an inspector, a safety manager, or the next supervisor knows what the garment is.

For the general logic of where to put marks on workwear, our guide to logo placement for custom apparel in Utah covers the visual side. On FR garments, the maker’s rules come first and the visual choices fit inside them.

If you need your own identification on top of the maker’s labels, such as a company care label or inventory tag, read our note on workwear compliance labels before you order.

What We See Go Wrong

Here is the paragraph from the shop floor. The most common problem is not a bad print. It is a crew that bought generic work shirts, assumed they were FR, and ordered 40 of them decorated before anyone checked the tag. Once the shirt has ink on it, you cannot return it. The second most common is a crew that buys real FR garments but asks for the same big back print they have always run on their regular tees. A third is people who send us garments that have already been laundered many times and ask us to add a logo. Fabric that is worn, thin, or has been repaired is a poor candidate for any decoration, and we say so.

We would rather turn down an FR order or send you back to the garment maker with a question than put a logo on something that should not carry one. That conversation costs you a phone call. The alternative can cost you a full order of garments.

Care and Washing After Decoration

Printed or stitched FR clothing has to be maintained like FR clothing, and the logo adds one more thing to watch. Duluth Trading’s FR user guide, a typical maker document, tells wearers to follow the label instructions, clean the garment often enough to remove contaminants, inspect it before and after each use and cleaning, and repair it only with FR fabric, thread, and components.

A few points matter specifically for decorated garments:

Contamination. OSHA says FR clothing contaminated with grease, oil, solvents, or other flammable substances should not be used, because contamination greatly reduces its effectiveness. Ink and a logo area can hold on to oils more than plain fabric does, so a grease-stained crew shirt is something to pull from service, not something to wash around.
Industrial laundering. ASTM F1449-20 says industrial laundering is an effective cleaning process for FR clothing, but the wearer must follow all care label instructions. Industrial washes are also hard on prints. If your crew uses a uniform service, ask them about wash temperature and dryer settings before we choose a method.
Wear. OSHA’s 1995 enforcement guidance notes that the FR properties of apparel can diminish after many washings or if the garment is incorrectly repaired or laundered. A cracked or peeling logo is a sign to inspect the garment, and damaged FR clothing should be replaced before work resumes.

The same guidance puts responsibility on the employer. It says employers are responsible for making sure FR properties of apparel are maintained, regardless of who supplies the clothing. If you hand out decorated FR shirts, that includes the shirts you decorated.

Ordering Checklist for Printed FR Apparel

Bring these to your quote request and the process goes quickly:

The garment brand, style, and fabric, plus the user information guide or decoration instructions.
The hazard standard your safety manager has specified.
Your logo in vector format, with the largest size you want to see on the garment.
The laundering method: home wash, uniform service, or industrial laundry.
The quantity, sizes, and the date you need them.

If you want proof that a decorated garment kept its certification, ask the supplier. The BSIF guidance advises buyers to request evidence that logos were retested on the garment or fabric, and to check the user information, declarations, conformity marks, and certificates. It also notes that logos of 10 square centimeters or larger need testing to be included in the certification. That is the UK framework, but the underlying question carries over: who tested the garment with this logo on it?

If you can supply that document from the garment maker, it protects you. We do not issue FR certifications and we do not claim a decorated garment is certified. We apply the decoration the maker allows and we do it cleanly.

Perspective: Why We Slow FR Orders Down

We run fast turnarounds on most jobs, and our customers like that. FR is the one category where we deliberately slow the first step. A short call about the garment and the standard saves more time than any press speed. We do not sell FR certification, and we do not tell crews that a print makes a garment safe. What we do is keep your logo small, keep it off the labels, use the method the maker allows, and tell you honestly when the answer is a plain garment with no decoration. In our experience, the crews that ask the garment question first rarely have a reorder problem.

For safety vests and reflective marks, which are a different category with different rules, see our page on printing on safety vests and the guide to reflective heat transfer that survives industrial washes.

FAQ

Can you print a company logo on flame resistant clothing?

Yes, in many cases, as long as the process does not compromise the garment’s flame-resistant properties. Keep the logo small, follow the garment maker’s instructions, and ask about decoration before you buy the garments. Some garments should not be decorated at all.

Is embroidery or screen printing better on FR shirts?

Neither is better in every case. Some makers consider embroidery riskier because of needle holes, while others allow small, simple stitched logos. Screen printing works for small one- or two-color marks where the maker permits ink. The garment’s instructions decide it.

How big can a logo be on an FR garment?

That depends on the garment maker and the standard. PIP’s guidance, for example, says non-FR emblems should be no larger than a credit card if they are used at all. Check the user information guide for your exact garment, and keep marks away from certification and care labels.

Does washing remove or weaken an FR logo?

Industrial laundering is an accepted way to clean FR clothing, but you must follow the care label. Prints can crack or fade with many washes, and OSHA notes that FR properties can diminish after many washings or improper laundering. Inspect decorated garments regularly and replace damaged ones.

Do you certify decorated FR garments?

No. We apply the decoration the garment maker allows. If your safety manager or insurer needs documentation that a decorated garment kept its rating, ask the garment maker or supplier for retest evidence and certificates.
