If you want custom T-shirts from a printer that stands behind its work, look past the word "guarantee" and read what it promises: a reprint, a refund, or only a fix for printing defects. Your realistic options are a local screen printer, a promotional products distributor, an online design-and-print service, or a print-on-demand storefront. Compare them on the written return or reprint policy, whether you see a proof before printing, how sizes and colors are handled, and the delivery date you can count on. For a small run you design yourself, online shirt printing is a quick way to go from artwork to a finished order. For large runs or specialty inks, a local shop will usually do better.

Your options for custom shirts, compared

• Local screen printer. Best for 48 or more shirts, specialty inks, and the ability to approve a printed sample in person. When something goes wrong, you can walk the shirt back into the shop. The San Luis Obispo Chamber of Commerce member services page links to its business directory, where you can look for printers and apparel decorators.

• Promotional products distributor. Useful when you want shirts plus other branded items from one supplier, and someone to source specific blank brands or fabrics.

• Online design-and-print service. Good for short runs and quick reorders. Consider Adobe Express. Its T-shirt page lets you design the full shirt or a pocket, sleeve or back area, pick a color, upload a photo or logo, and order in various sizes. It lists free shipping and returns, ships in 100% recyclable packaging, and prints and ships only in the US, UK, Australia and Canada. The page doesn't describe fabric, so ask before you order for a team.

• Print-on-demand storefront. Lets customers or fans buy one shirt at a time, with printing and shipping handled per order. Good for merch with unpredictable demand, not for outfitting a booth crew by a deadline.

When an online service isn't the right fit: if you need 300 shirts for a race, want water-based inks on a specific organic blank, or need to try on sizes before committing, a local screen printer is the stronger choice.

What does a T-shirt printing guarantee actually cover?

Printers use the word in very different ways. Some will reprint any shirt with a defect. Some refund the order if you're unhappy for any reason. Some cover only misprints, not sizing mistakes you made on the order form.

The FTC's guides on advertising warranties and guarantees set a useful baseline. They say "Satisfaction Guarantee" or "Money Back Guarantee" should be used only if the seller refunds the full purchase price at the buyer's request, and that any material limits or conditions should be disclosed clearly. If a printer's guarantee comes with conditions, they should be easy to find.

Before you order, ask four questions:

1. Does the policy cover custom-printed items, or only blanks?

2. Is the remedy a reprint, a refund or a credit?

3. How long do you have to report a problem after delivery?

4. Do you need to return the shirts, or just send photos?

How do I compare satisfaction guarantees on custom apparel?

Put two or three printers' policies side by side and compare remedies, not adjectives. "Satisfaction guaranteed" with a 30-day refund window means more than "quality you can trust" with no written policy at all.

A few habits protect you whichever printer you pick:

• Approve a proof. Check spelling, colors and the placement of the logo relative to the collar.

• Order one sample if the shirt will be worn by a team for a full season.

• Photograph the order on arrival, before anything is washed, so a claim is easy to document.

• Confirm sizes in writing. A guarantee rarely covers an order form that listed the wrong sizes.

If you plan to sell shirts, not just give them away, the FTC's textile labeling guide explains that most clothing sold to consumers needs labels showing fiber content, country of origin and the manufacturer or dealer. Ask your supplier whether the blanks already carry compliant labels.

Worked numbers: shirts for a conference booth

Say you run a startup and you're exhibiting at a trade show with four staff on the booth. A sensible order looks like this:

• Staff shirts: two per person for a two-day show, so 8 shirts. Add a third for anyone working setup or teardown.

• Giveaway shirts: if you expect around 150 meaningful conversations, 40 to 60 shirts for people who sit through a demo or join your list is plenty. Skew the size mix toward medium and large.

• Spares: two or three in the most common sizes.

Then count backward from the show:

• Six weeks out: final artwork and size list.

• Five weeks out: proof and one sample shirt.

• Four weeks out: approve and place the full order.

• Two weeks out: shirts arrive. Check every box against the order before you pack for the show.

If the event has an exhibitor agreement, read it before you pay the booth fee, especially cancellation terms and what the organizer provides. Adobe's guide on how to read a business contract before you sign it is a handy prompt for that review.

Shirts and totes around San Luis Obispo

The San Luis Obispo Chamber of Commerce dates to 1904 and has nearly 1,400 members. Its late-spring EXPO at the Expo is billed as the largest business trade show on the Central Coast, with more than 100 local exhibitors and about 2,000 attendees. Setup opens at 10 a.m. and booths must be finished by 2:30 p.m., so staff shirts should arrive in hand well before the day. The page also notes that the first 1,000 attendees receive a free tote, so a booth budget may go further on shirts or samples than on bags.

Totes still have a place elsewhere. A startup putting together new-hire kits, or a shop that sells at the Thursday night Downtown SLO Farmers' Market, which runs on Higuera Street between Osos and Nipomo with more than 100 vendors, can use personalized tote bags to carry purchases and its name down the street. Match the tote artwork to the shirt so the brand reads the same.

Shirts also work at the chamber's monthly Membership Mixers, held on the third Wednesday at a host member's business. A host can put staff in matching shirts so guests know who to ask.

For startups weighing merchandise as a product line, the Small Business Development Center at Cal Poly, housed in the CIE HotHouse downtown, offers free and confidential advising for San Luis Obispo County businesses.

Frequently asked questions

Do custom T-shirt guarantees cover sizing mistakes?

Usually not, if the wrong size came from your order form. Most cover print defects or damage. Read the written policy before you order.

What should I check before approving a shirt proof?

Spelling, colors, logo size and placement, and the shirt color. Ask for a sample if the order is large or the shirts will be worn often.

How many shirts should a startup bring to a trade show?

Two per staff member for a two-day show, plus 40 to 60 giveaways for serious conversations, is a practical starting point.

Do shirts I sell need fiber and origin labels?

The FTC says most clothing sold to consumers needs fiber content, country of origin and dealer labels. Check that your blanks carry them.
