Features

Niche-Tuned Designs

Every design starts with a niche brief — buyer persona, exact search phrases they use, and visual codes that convert in their world. Never generic, never templated.

Print-Ready, Every Platform

PNG at 300 DPI in the exact dimensions for Etsy, Amazon Merch, Shopify, Redbubble, and Shine On. Source files (PSD/AI) included. Upload-ready day one.

2 Revisions Included

Two revision rounds per design baked in. We iterate until you sign off. Rush 24-hour turnaround available at +50% for projects that cannot wait.

Designs Built for Every POD Platform You Sell On

Each platform has its own rules — image dimensions, color profile, content policies, and most critically, what actually sells there. Etsy buyers want handmade-feel typography and emotional gifting hooks. Amazon Merch needs thumbnail-readable designs and trademark-safe phrasing. Redbubble allows imagery Merch bans. Shopify DTC audiences want premium brand aesthetics.

We deliver platform-correct files for all of them. Tell us where you’re selling and we build to that platform’s exact specs and buyer expectations. One design, optimised for the channel you actually sell on.

Why Choose Us

Why Choose Prinil for Custom T-shirt Designs

Prinil is a POD-only design studio — we work exclusively with print-on-demand sellers across Etsy, Amazon Merch, Shopify, Shine On, and Redbubble. No generalist agency work, no template recolours, no AI shortcuts. Our team is small by design: you talk to the designer doing your work, not an account manager handing it off to a junior. Most clients hit their first $1K month within 12 weeks of launching designs we shipped them.

Every t-shirt design starts with a 30-minute niche brief — we map the buyer's identity, the exact search phrases they use, the visual codes they recognise, and the competitor designs already winning in that space. Then we design.

What this means for you: your designs feel made-for-them, rank for the words buyers actually type, and convert without paid ads.

PNG (4500×5400, 300 DPI, transparent), JPG, AI/SVG source files, PDF for print. Direct compatibility with Printify, Printful, Gelato, Gooten, Customily, Pillow Profits, and every major POD generator. Upload-ready the moment you receive them — no resizing, no format conversion, no reshooting.

Two revision rounds on every t-shirt design as standard. We iterate until you sign off — typography tweaks, colour adjustments, layout refinements, copy changes. Additional rounds are $15 each, or included free in bulk packages of 25+ designs. Rush 24-hour turnaround available at +50% for time-critical drops.

Every phrase and visual element checked against the live USPTO trademark database before delivery. No NFL team names, no Disney references, no song lyrics, no celebrity references. We will not put your shop at risk — and we will flag risky phrasing in your brief before we start, not after.

Track record: zero trademark takedowns across 500+ designs shipped for 200+ POD brands.

Frequently asked questions

What file formats will I receive?
You receive print-ready PNG at 300 DPI in the exact dimensions for your platform (Amazon Merch 15×18, Etsy 12×16.5, etc.), plus the editable source file (PSD or AI) so you can repurpose later.
How many revisions are included?
Every design includes 2 rounds of revisions. Additional rounds are billed at $15 each or included in bulk packages.
Are designs exclusive to me?
Yes — once final payment clears, full IP rights transfer to you. We can also display the work in our portfolio unless you request confidentiality (NDA available).
Do you check for trademark conflicts?
Yes. We run every phrase through the USPTO trademark database and avoid known infringing phrases. We will not knowingly produce work that puts your store at risk.
How fast is a single design?
Standard turnaround is 48–72 hours from brief approval. Rush 24-hour delivery is available for +50%.
Can you match an existing brand style?
Yes. Share your brand guidelines (or a Pinterest board of references) and we will deliver designs that fit your existing collection.
What if I'm not happy with the result?
You get 2 revision rounds to bring the design to spec. If the design fundamentally misses the brief, we will redo it. Refund policy in our Terms.
Do you do AI-generated designs?
No. AI gets flagged by Etsy and Amazon Merch in 2026 and we will not put your store at risk. We use AI for brainstorming, never for production output.
