Print-on-demand affiliate programs are an unusually good fit for content sites, because the audience is actively looking for a supplier and the decision has a long consideration window. They are also frequently misreported — rates quoted on roundup sites are often years out of date. What follows is taken from each company’s own published terms, with the gaps flagged rather than filled in with guesses.

The programs at a glance

Printful

Printful’s published affiliate policy is specific on mechanics and silent on the headline rate. It confirms a 30-day cookie, an affiliate period of 12 months from the referred customer’s first order, commissions on eligible products and on Growth plan subscriptions (the latter as a one-time payment), and exclusion of tax and shipping from the commission calculation. Payouts are via PayPal in USD, within one to three business days of a withdrawal request, with a $25 minimum.

Third-party directories widely list the rate at around 10%, but since Printful does not state it in the public document, treat that as indicative and confirm it in your own dashboard before building revenue projections on it.

The 12-month affiliate period is the valuable part. Print-on-demand sellers who stick around generate recurring product volume, so a referral that works is worth considerably more than a single-order bounty. Printful’s program details are here.

Printify

Printify is the clearer of the two: 5% of what your referrals spend, for 12 consecutive months, with a 90-day cookie. Payouts go monthly to PayPal. The program runs through PartnerStack, applications take a couple of minutes and are reviewed within about two working days.

The 90-day cookie is three times Printful’s and matters more than it sounds. Someone researching print-on-demand suppliers in January frequently does not open an account until March. Printify’s program is here.

Shopify

Shopify’s program pays per qualifying merchant signup rather than as a share of ongoing spend, with the amount varying by region and the plan the merchant takes. It runs through Impact and has a 30-day cookie. It is the highest per-conversion payout of the three and the least durable, since there is no trailing revenue once the bounty is paid.

For a print-on-demand audience it works well as a secondary offer — the person setting up a store needs both a storefront and a supplier, so the two referrals sit naturally in the same article. Shopify’s affiliate program is here.

Tool and research programs

Research and design tools convert at lower volume but often at better rates, and they attract buyers who are already committed enough to pay for software. Merch Informer and Merch Titans both operate affiliate programs on their subscription products. Because these are recurring SaaS subscriptions rather than one-off purchases, a small number of conversions can produce steadier monthly income than a larger number of supplier referrals.

Which to prioritise

Frequently asked questions

Most “best AI tools for print on demand” lists are rankings of image generators. That misses the point. A print-ready design passes through four or five distinct stages, and the stage that kills most AI-generated designs is not generation — it is everything after it. A beautiful 1024-pixel image with a white box behind it is not a product.

The non-negotiable technical requirements

Stage 1: Image generation

The current generation of image models all produce commercially usable artwork; they differ in style and control rather than raw quality.

Midjourney remains the strongest for stylised illustration and the kind of bold graphic work that sells on apparel. Its weakness is precise control — getting a specific composition out of it takes iteration.

Adobe Firefly is the pragmatic choice for anyone nervous about training-data provenance, since Adobe trains on licensed and public-domain material and offers commercial indemnification to eligible customers. For a business selling physical goods, that is a real risk reduction rather than a marketing line.

Ideogram is the notable exception on text. Most image models mangle lettering; Ideogram handles it far better than the field. It still does not beat setting type properly yourself, but it is the one worth trying for text-led concepts.

DALL·E, via ChatGPT is the most convenient for conversational iteration and the weakest for stylistic control. Useful for concepting, less so for final artwork.

A practical workflow that beats arguing about which is best: generate the illustration in whichever model suits the style, generate it without text, and add the typography yourself.

Stage 2: Upscaling

This stage is skipped more often than any other and causes more rejected or refunded orders than any other. Generators typically output at around 1024–2048 pixels. You need 3600×4800 for a standard front print.

Topaz Gigapixel is the quality benchmark and a one-off purchase rather than a subscription. Upscayl is free, open source and runs locally — genuinely good enough for most apparel work and the right starting point if you are watching costs. Midjourney’s own upscale is adequate but generally not sufficient on its own for large prints.

Whatever you use, open the result at 100% zoom and look at the edges before you upload. Upscaling invents detail; sometimes it invents the wrong detail.

Stage 3: Background removal

remove.bg and Adobe Express both handle clean subjects well. Photoshop’s subject selection is better on complex edges — hair, fur, fine linework — where automated tools leave halos.

The failure mode to watch for: a result that looks transparent in a preview with a white page behind it but still carries a fringe of near-white pixels. View it against a dark background before accepting it. That fringe is exactly what shows up as a grey halo on a black shirt.

Stage 4: Vectorising

Needed for embroidery, and worth doing for any bold graphic design because a vector scales to any product size without regenerating.

Adobe Illustrator’s Image Trace is the most controllable. Vectorizer.AI handles AI-generated artwork notably well and is the better option if you do not already have Illustrator. Expect to clean up the result by hand either way — automatic tracing of a detailed illustration produces a mess of paths that needs pruning.

Stage 5: Research and listing copy

This is where language models earn their keep, and it is the least glamorous part of the stack.

Use a model such as Claude or ChatGPT to turn validated keyword research into listing titles, bullet points and descriptions that respect each marketplace’s character limits. The critical discipline is to supply the keywords rather than let the model invent them — a model asked to guess what buyers search for will produce confident, plausible, wrong answers.

For the research itself, pair the model with real data. A dedicated tool such as Merch Informer gives you marketplace demand and competition figures; the model turns those figures into listings. Using the model for both halves is how people end up with 200 well-written listings for products nobody searches for.

Stage 6: Mockups

Both major suppliers include this at no cost. Printful‘s Design Maker and Mockup Generator are available on the free plan, as is the equivalent on Printify. Placeit is worth paying for only if you want lifestyle photography with models in settings, which converts better on an own-brand store than a supplier mockup on a plain background does.

A minimum viable stack

Frequently asked questions

Printful and Printify are the two suppliers most print-on-demand businesses end up choosing between, and the comparison is genuinely close. They are, however, structurally different companies, and that difference — not the feature lists — is what should decide it for you.

The structural difference that matters

Printful owns and operates its own fulfilment centres. When you place an order, Printful prints it. That gives it direct control over print quality, colour consistency and turnaround, and it means a shirt ordered in March looks like a shirt ordered in September.

Printify is a marketplace of independent print providers. When you place an order, Printify routes it to one of many third-party printers. That gives it a far larger provider network, lower base costs through competition, and better geographic coverage — but quality varies by provider, and two orders of the same product can be fulfilled by two different factories.

Everything else follows from that.

Printful vs Printify at a glance

Pricing

Printful’s “free when you reach $12,000 a year in sales” term on the Growth plan is the more generous structure for a business that is actually working. Printify’s annual billing is the cheaper entry point if you want the discounts immediately. On base product cost, Printify is usually the cheaper of the two, and at volume that difference compounds faster than any subscription saving.

Print quality

This is where the ownership model shows. Printful is the more consistent of the two, and if you are building a brand where a customer might order twice, consistency is worth paying for. Printify’s ceiling is high — its best providers are excellent — but the floor is lower, and you will only know which you have been allocated by ordering samples from the specific provider you intend to use.

Printify does let you choose your print provider rather than accepting the default, and experienced Printify sellers treat provider selection as a core skill rather than a setting. If you are not prepared to do that work, Printful removes the problem for you at a higher unit cost.

Product range

Printful lists around 579 customisable products on its current catalogue — broad, well-photographed and tightly specified. Printify’s catalogue is larger in raw count because it aggregates many providers, which means more variety but also duplicate products at different prices and quality levels. More choice, more decisions.

Printful also offers in-house embroidery, cut-and-sew and branding extras such as inside labels and packing inserts, which are harder to coordinate across a distributed network.

Integrations

Both connect to the platforms that matter: Shopify, Etsy, WooCommerce, eBay, Wix, Squarespace, BigCommerce and Amazon, plus APIs for custom builds. Printful supports a slightly wider set of niche platforms and offers Quick Stores for sellers without a storefront of their own. For the overwhelming majority of sellers, integration availability will not be the deciding factor.

Shipping

Printify’s distributed network gives it an advantage on international orders, because it can often route to a printer in or near the destination country rather than shipping across a border. Printful operates facilities across multiple regions too, but the network effect favours Printify on breadth. If a large share of your orders will land outside your home market, price a realistic basket on both before deciding.

Pros and cons

The verdict

Frequently asked questions

Print on demand in 2026 is a different business to the one people wrote guides about in 2020. The supplier side has consolidated, the marketplaces are saturated with generic designs, and the single biggest change is that design generation — once the bottleneck — now costs minutes instead of days. That shifts where the money is made. It is no longer made by whoever can produce a design; it is made by whoever can find a niche worth designing for and get listings in front of buyers.

This guide walks through the build in the order it actually makes sense to do it.

What print on demand actually is

You upload a design. A supplier holds the blank garments, prints your design when an order comes in, and ships it to the customer under your branding. You never buy stock, never hold inventory, and never touch a parcel. In exchange, your per-unit cost is far higher than bulk printing, so margins are thin and volume matters.

Two models sit underneath that:

• Marketplace selling — you list on Amazon Merch on Demand, Etsy or Redbubble. They bring the traffic; you compete on design and keywords, and you accept their fees and their rules.
• Own-store selling — you run a Shopify or WooCommerce store connected to a supplier. You keep more margin and own the customer, but you must generate every visitor yourself.

Most people who reach meaningful income do both: marketplaces for discovery and cash flow, an own store for margin and brand equity.

Step 1: Pick a niche before you generate a single design

This is the step AI has made more important, not less. When design production was slow, a mediocre niche with decent designs could still work because few people bothered. Now that anyone can produce 200 designs in an afternoon, the generic niches — “funny cat shirt”, “fishing dad” — are flooded within weeks of becoming viable.

What still works is specificity. Not “nurses”, but “paediatric oncology nurses”. Not “running”, but “ultramarathon pacers”. The audience is smaller, but the buyer recognises themselves in the design, and almost nobody is competing for the exact phrase.

Use AI for the ideation sweep, then validate with real data. Ask a model to produce 50 sub-communities inside a broad interest, with the in-group vocabulary each uses. Then check actual demand in a research tool such as Merch Informer or by searching the marketplaces directly and looking at best-seller rank, review counts and listing age. AI is excellent at generating candidates and unreliable at telling you whether people buy — it will confidently invent demand that does not exist.

Step 2: Choose your supplier

For most people starting now, the choice is between two suppliers.

Printful runs its own facilities, which means more consistent print quality and tighter control over fulfilment, at a higher base cost per item. Its free tier gives access to the full catalogue, unlimited stores and the design and mockup tools; the paid Growth plan at $24.99/month adds product discounts of up to 33% and is free once you pass $12,000 a year in sales.

Printify is a network rather than a factory — it routes your order to one of many third-party print providers. That gives you lower base costs and broader geographic coverage, at the cost of variable quality between providers. Its free plan covers five stores with unlimited designs; Premium runs from $39/month, or from $24.99/month billed annually, and brings up to 33% off products.

The practical approach: start on both free tiers, order samples of your top three products from each, and let the physical items decide. Print quality on a dark heather garment will tell you more than any review, including this one. The full Printful vs Printify comparison is here.

Step 3: Use AI for design, but understand the trap

Image models will produce attractive artwork quickly. Three things will sink you if you ignore them.

Resolution and print format. Most models output at a size that looks fine on screen and prints badly. You need roughly 300 DPI at final print dimensions — for a 12×16 inch front print, that is 3600×4800 pixels — with a genuinely transparent background. Upscaling a 1024px image to that size does not add detail; it adds blur. Generate large or upscale with a dedicated tool, then check the file at 100% zoom before uploading.

Text. Image models still mangle lettering. Generate the artwork without text, then set the type yourself in a vector editor. This is also where most of the differentiation lives — the phrase matters more than the illustration in the majority of selling shirts.

Rights. You cannot sell a design built on someone’s trademark, and “the AI made it” is not a defence. Check the mark before you list, not after you get the takedown. The same applies to recognisable characters, logos and band names, however much the model is willing to draw them.

The full AI tool stack, stage by stage, is here.

Step 4: Listings are where AI pays for itself

Writing 200 distinct listings with varied, keyword-aware titles, bullet points and descriptions is the single most tedious job in this business, and it is one language models do genuinely well. Feed the model your keyword research and your design concept, and have it produce variations that stay inside each marketplace’s character limits and prohibited-word rules.

The discipline is to give it the keywords rather than let it guess them. A model asked to “write an SEO title for a nurse shirt” produces generic filler. The same model, given the eight phrases your research says buyers actually type, produces listings that rank.

Step 5: Price for the margin you need

Work backwards. Take the supplier base cost, add shipping if you are absorbing it, add the marketplace or payment fee, and then set your price so the remainder is a number worth having. On a typical t-shirt in 2026 that usually means a retail price in the $22–30 range to keep anything like a healthy margin, and competing below that on a print-on-demand cost base is a route to working for nothing.

If you are running your own store, remember the customer acquisition cost sits on top of all of that. A store with no organic traffic and paid ads at current rates frequently loses money on the first order and only makes sense if you have a plan for the second.

What a realistic first 90 days looks like

That last step is the one most people skip. Print on demand rewards iteration on proven sellers far more than it rewards volume of new ideas, and the sellers who compound are the ones who notice what worked and make twenty more of it.
