The best artwork file for a custom shirt is usually the cleanest original version of the design—not a screenshot, social-media download, or image copied from a website. A vector file such as SVG is useful for logos and simple graphics because it can be resized without losing sharpness. A high-resolution PNG with a transparent background can also work well, especially for detailed or full-colour artwork.
If you do not have an ideal file, do not abandon the project. Send the best version you have and explain where it came from. The RAD Studio reviews artwork before payment and production, so you can find out whether the file is usable, needs a cleaner export, or should be rebuilt before it is printed.
Vector artwork versus raster images
Vector files build a design from shapes and paths rather than a fixed grid of pixels. That allows a logo or illustration to be enlarged without becoming blurry. SVG is a common vector format that can also be uploaded to The RAD Studio's online clothing designer. Original design files may also exist as AI, EPS, or some PDFs, although a PDF is not automatically vector just because of its file extension.
Vector artwork is particularly useful for logos, lettering, line art, and graphics with clean colour areas. It makes it easier to adjust print dimensions, preserve edges, and separate design elements when production preparation requires it.
Raster images—including PNG, JPG, and WEBP—are made from pixels. They can print well when they contain enough real image detail at the intended print size. The problem appears when a small raster image is stretched far beyond its original dimensions. The software can enlarge the pixels, but it cannot recreate detail that was never present.
When a transparent PNG works well
A transparent PNG is often a practical choice for custom shirt artwork. Transparency removes the rectangular background around the design so that only the intended artwork appears on the garment. This is especially important when a logo was originally placed on a white page or exported with a solid background that was never meant to print.
The image should still be large enough for the intended print. A PNG that looks sharp as a small phone icon may not contain enough detail for a large full-front or full-back design. View the image at approximately the size it will be printed. If the edges already look jagged, soft, or blocky, enlarging it will not make them cleaner.
Transparency should also be intentional. If the design includes white lettering or white details, those elements may be difficult to see when the file is previewed against a white screen. That does not necessarily mean they are missing. Tell the studio what garment colour you plan to use so the artwork can be reviewed in context.
Why screenshots and downloaded images can cause problems
Screenshots are built for screens, not production. They may include unwanted backgrounds, interface elements, compression, or very limited dimensions. Images saved from Facebook, Instagram, messaging apps, and websites may have been reduced or recompressed even when the original artwork was much better.
Changing the number in a DPI field does not restore missing detail. If a small image is labelled as higher resolution without adding genuine image information, it remains the same small image internally. The most useful fix is to locate the original file from the designer, logo creator, sign company, previous printer, Canva project, or organization records.
If the screenshot is truly the only version available, submit it as a reference. It can still show what the design should look like, even if a cleaner production file must be found or prepared.
Preparing Canva and text-based designs
For Canva artwork, keep the original editable project and export the cleanest version available. Avoid taking a screenshot of the Canva canvas. If the design uses transparency, confirm that the exported file actually preserves it. Keep important text and graphics away from the very edge of the artwork, and check that all spelling, dates, names, and phone numbers are final.
Text-heavy designs deserve extra attention. Very thin lettering, tiny type, distressed textures, and fine outlines may not reproduce the way they appear on a large monitor. The physical print size matters: text that is readable across a computer screen may be much smaller when placed on a left chest or sleeve.
If names, numbers, or departments change from garment to garment, provide one checked roster. Do not embed every variation into one confusing image. The project should clearly connect each name or number with its correct garment and size.
Artwork for dark and light garments
The garment colour changes how artwork is perceived. Dark designs can disappear on black or navy clothing, while white or pale artwork may be invisible against a white preview background even though it is intended for a dark shirt. Full-colour artwork may also need enough contrast to remain readable from a normal viewing distance.
Use the online clothing designer to preview the general relationship between the garment colour and artwork. The mockup helps communicate your intention, but it is not a colour-matching guarantee. Screens, garment dyes, source artwork, and print production all affect colour, so the studio confirms the production details during approval.
What to upload to the online clothing designer
The RAD Studio clothing designer currently accepts PNG, JPG, WEBP, and SVG artwork for the garment preview. Choose a real garment, select its colour, add the size breakdown, and build each available print location separately. You can move, resize, and rotate the design to communicate the placement you want.
The original uploaded artwork is submitted with the generated mockups. That matters because the studio needs the source file for quality review, not only a screenshot of the preview. If you have a separate original design file that the preview does not accept, keep it available for the project conversation rather than replacing it with a lower-quality copy.
The designer does not take payment automatically. The RAD Studio checks the garment, stock, artwork, physical print dimensions, placement, quantity, sizes, timing, pickup or Canadian shipping, and final price before sending an approval and payment step.
Artwork submission checklist
Before submitting, check the following:
- Use the original file whenever possible.
- Prefer vector artwork for clean logos and lettering.
- Use a sufficiently detailed PNG when vector artwork is unavailable.
- Remove an accidental background or explain if the background is intentional.
- Confirm spelling, dates, names, and numbers.
- Choose the garment colour before judging design contrast.
- Build every required print location separately.
- Include the complete size and quantity breakdown.
- Keep any original AI, EPS, PDF, or editable design file available.
- Explain anything the mockup cannot show accurately.
The purpose is not to make customers become print technicians. It is to give the studio enough reliable information to prepare the order correctly.
Frequently asked questions
Is a PNG good enough for custom shirt printing?
A transparent PNG can work well when it contains enough real image detail for the intended print size. A very small PNG will not become sharp simply because it is enlarged.
Does my artwork need a transparent background?
Use transparency when the background is not intended to print. If the rectangle or background colour is part of the design, keep it and explain the intended result.
Can you print a screenshot or image from my phone?
A screenshot can be reviewed as a reference, but it may not contain enough detail for production. Send the original file if it can be located, along with the screenshot if it helps explain the design.
Do I need a vector file?
Not for every project. Vector artwork is preferred for many logos and simple graphics because it resizes cleanly, while a sufficiently detailed transparent PNG may work well for other designs.
Can I submit artwork made in Canva?
Yes. Keep the editable Canva project and export a clean file rather than taking a screenshot. Check transparency, spelling, dimensions, and design contrast before submitting.
What if my logo file is too small?
Send the best available version and explain what you have. The studio can review whether it is usable and identify what should be corrected before approval. Do not assume that changing the DPI label repairs a low-detail image.
