A blurred logo, a missing background, or a tiny image stretched across the back of a hoodie can turn a great idea into a disappointing print. If you are asking what file formats print best, the short answer is PDF for logos and graphics, and high-resolution PNG for most image-based designs. The right choice still depends on the artwork, garment and print method.
For a one-off birthday T-shirt, a run of branded workwear or event merchandise needed at short notice, sending usable artwork from the start saves time and keeps the result looking sharp. Here is what to supply, what to avoid, and when a file that looks fine on screen is not ready for print.
What file formats print best for garments?
A print-ready PDF is usually the strongest all-round option for logos, text, illustrations and clean graphic designs. It can retain vector artwork, meaning the design can be resized without becoming blurry. This is particularly useful for chest logos, large back prints, sleeve branding and repeat orders where the same artwork may be used in different sizes.
A PNG is often the best choice for artwork containing photographs, detailed textures or soft edges, especially where a transparent background is required. Supply it at high resolution and at, or larger than, the size you want printed.
There is no single format that wins every job. Screen printing and vinyl work favour vector files. DTF and DTG can produce excellent results from well-prepared PNGs and PDFs. Sublimation needs high-resolution image artwork, while embroidery requires a separate digitised stitch file created from your supplied logo.
Vector files: best for logos, lettering and bold graphics
Vector artwork is made from lines, curves and shapes rather than a fixed number of pixels. That means it stays crisp whether it is printed as a small left-chest logo or enlarged for the back of a jacket.
PDF, AI and EPS are common vector formats. Of these, PDF is generally the easiest and most practical file to send because it is widely used and can preserve vector information. If you have an original Adobe Illustrator file, send it too where possible, but do not worry if you only have a properly exported PDF.
Vector is the preferred route for clean company logos, names, numbers, single-colour graphics, signage-style lettering and designs intended for vinyl or screen printing. It also makes colour separation simpler when a design uses specific spot colours.
Before exporting a PDF, convert fonts to outlines if you can. This prevents a font being substituted if it is not installed on the production system. Keep the artwork at its intended dimensions, remove hidden layers and avoid placing a low-resolution JPG inside a PDF. A PDF is only as good as the artwork within it.
PNG files: best for detailed artwork with transparency
PNG is ideal when your design includes a photo, complex illustration, faded edges, gradients or a transparent background. It is widely suitable for DTF printing, DTG printing and other digital garment-printing workflows.
The key is resolution. Aim for 300 dpi at the final print size. For example, if you want a 30 cm-wide front print, the supplied image should be approximately 3,543 pixels wide. A 1,000-pixel image may look perfectly acceptable on a phone but will not have enough detail for a large garment print.
Transparency matters too. A PNG with a transparent background allows the print to follow the shape of the artwork. A white box behind a logo is not removed automatically simply because the logo itself has a white background on screen. Check the file on a coloured background before sending it. If the box is still visible, it is part of the image.
Formats that can work, but need care
JPEG files are fine for high-quality photographs where no transparent background is needed. They are common, compact and easy to send. The drawback is compression: every time a JPEG is saved repeatedly, some image information can be lost. For a photo printed as a rectangle or full design area, a high-resolution JPEG can be perfectly suitable. For a logo that needs a transparent background, choose PNG instead.
TIFF files can hold excellent-quality image data and are sometimes used by designers or photographers. They are usually much larger than necessary for a straightforward garment order, so they can be slower to upload and share. Send one if it is your best original image, but a correctly sized PNG or PDF is normally more convenient.
SVG files are vector-based and can be excellent for simple graphics. However, not every production workflow handles every SVG feature consistently, particularly unusual fonts, effects or masks. Exporting the design as a print-ready PDF is usually the safer option.
PSD files can be helpful when the artwork needs adjustment, but they should be supplied with all necessary layers and fonts included where relevant. If you have a PSD, it is sensible to also export a flattened high-resolution PNG or PDF so there is a clear reference for how the finished design should look.
Files to avoid for print artwork
A screenshot, image copied from a website, social media download or photo of a previous printed garment rarely gives a clean result. These files are typically low resolution, compressed and not designed for enlargement. A website logo may be only 300 pixels wide even though it appears sharp in a browser.
Word, PowerPoint and Canva exports can work for simple jobs, but they are not automatically print-ready. If you create artwork in Canva, export it as PDF Print for text and vector-style designs, or as a high-resolution PNG with a transparent background where needed. Check that the design is at the correct physical size before downloading it.
Avoid sending artwork through apps that reduce quality. Messaging services and social platforms often compress images. Use the original file from your device or cloud storage rather than a screenshot of it. If you are ordering a rush job, this small step can prevent a delay while replacement artwork is requested.
Match the file to the print method
The best file format changes with the production method, not just the garment.
For DTF printing, high-resolution PNG files with transparency are excellent, while PDF vector artwork is also ideal for logos and solid graphics. DTF handles full colour, fine detail and small runs well, making it a practical option for personalised names, event T-shirts and promotional clothing.
For DTG printing, use a high-resolution PNG or TIFF for detailed art and photographs. A transparent background is useful for designs that should sit directly on the fabric. Very faint elements can behave differently on dark garments because a white underbase may be needed, so strong contrast often gives the most reliable result.
For screen printing, vector PDF, AI or EPS files are preferred. Clean, separate colours produce the strongest outcome and help keep setup straightforward. Screen printing is particularly effective for bulk orders with bold designs, but photographic artwork may need specialist preparation or a different method.
For vinyl printing, vector PDFs are the clear favourite. The cutter follows the artwork’s paths, so clean shapes and lettering matter. Fine detail, distressed textures and very small text may not be suitable for cut vinyl, even if the file itself is technically vector.
For sublimation, provide high-resolution PNG, JPEG or TIFF artwork at final size. The process works best on suitable light-coloured polyester items, and image quality is especially visible across large print areas.
For embroidery, do not worry about supplying a DST or other machine stitch file unless you already have the correct version. Send the best logo you have, ideally a vector PDF, AI or EPS. It can then be digitised to suit the fabric, placement and finished size. A logo that prints brilliantly may need simplification for embroidery, particularly if it contains tiny text or intricate shading.
Colour: do not let the file setting cause confusion
Customers often assume every print file must be converted to CMYK. That is not always true. Many digital garment printing workflows use RGB artwork and colour-managed RIP software, while screen printing may use spot colours or Pantone references for accurate brand matching.
The practical approach is simple: send the original high-quality file and state any non-negotiable brand colours. If your business uses a Pantone reference, include it. If colour matters for uniforms, franchise branding or sponsor logos, say so before production rather than relying only on how a colour appears on your screen.
Screens vary, fabric colours affect the final appearance, and a print on black cotton will not look exactly the same as one on white polyester. The aim is controlled, consistent production, not a guess based on a mobile display.
A quick artwork check before you place the order
Open the file at 100% size where possible. Check spelling, phone numbers, dates and social handles carefully. Make sure the intended background is transparent, and confirm that thin lines and small text are still readable at the actual print size.
For a chest logo, small detail may be manageable. For a large back print, low resolution becomes obvious quickly. Tell the printer the required placement and approximate size, especially if the same design is needed across adult, children’s and different garment sizes. A design that works at 28 cm wide on an adult hoodie may need resizing or adapting for a child’s T-shirt.
If all you have is a low-quality logo, send it before placing a large order. It may be possible to redraw it as vector artwork, simplify it for vinyl or embroidery, or recommend a print size that still looks professional. Honest artwork advice is better than printing a weak file and hoping for the best.
The fastest route to a sharp result is to send the highest-quality original you can find, explain where it is going, and ask if anything needs adjusting. East London Printers can then match the artwork to the right production method, whether you need one personalised tee today or branded workwear for the whole team.
