Great DTF transfers start with great artwork.

At Armor Ink, we see all kinds of files come through every day. Some are ready to print right away. Others are screenshots, shirt mockups, logos pulled from Facebook, or small images that have been stretched much bigger than they were ever meant to be.

We can print some incredibly detailed, vibrant transfers, but we cannot create detail that was not there to begin with.

The good news is you do not have to be a graphic designer to get a great result. A few quick checks before you upload can save you from blurry artwork, unwanted white boxes, fuzzy outlines, or a transfer that does not look like you expected.

Start With the Size You Actually Want Printed

This is probably the biggest thing we see.

If you want a large back print, start with artwork made for a large back print. If you want a small left-chest logo, start with artwork sized for a left chest.

We recommend 300 DPI for clean, sharp transfers, but you do not have to get too caught up in the technical side of it. The simple rule is this:

Do not take a small image and stretch it into a large print.

A 3-inch logo may look fine on your phone or computer screen. Stretch that same file into a 12-inch back print, though, and it can start looking blurry, jagged, or fuzzy.

Making an image bigger does not add detail to it. It just makes the existing pixels less sharp as information is lost.

Before you upload, look closely at your artwork. If it already looks rough, blurry, or pixelated on your screen, it will probably print that way too.

Use the Original Artwork File Whenever Possible

The original artwork file is always better than a screenshot, website image, or social-media post.

For most designs, a high-quality PNG with a transparent background is a great option. If you have a clean logo file in vector formats like, SVG, PDF, or AI, those files can be even better because they stay sharp at different sizes.

Here is the simple breakdown:

PNG: Great for most shirt designs and artwork with transparent backgrounds.
SVG, PDF, or AI: Great for logos, lettering, mascots, and clean graphic artwork.
JPG: Not always bad, but usually not our first choice. JPG files do not support true transparency and will require background removal which can lead to issues.

Avoid sending us:

Screenshots
Shirt mockups
Facebook or Instagram images
Images copied from a website
Photos of another printed shirt
Tiny logos stretched way larger than the original

Those are the files that most often cause us to reach out needing you to upload a corrected version.

Make Sure Your Background Is Actually Transparent

A transparent background simply means only your design prints.

This sounds simple, but it is one of the most common issues we run into. Sometimes a design looks transparent on a white screen, but it actually has a white box around it that you can't see with your phone. In the world of Chatgpt and AI we often see generated images that have a checkerboard background behind the design that the AI mistook for a transparent background but was not.

If that background is in the file, it will print.

Before uploading, make sure:

There is not a white or color behind the design.
The checkerboard pattern is not actually part of the image itself and disappears when viewed in photo editing software.
You are uploading the actual artwork file, not a screenshot of it.
The edges are clean and do not have leftover background pixels around them if you used background removal software.

Background-removal tools can be helpful, but they are not perfect. They can leave faint edges around lettering, hair, small details, or irregular shapes. They can also miss some parts entirely, or remove parts of your design that you wanted to keep.

Watch for White Halos and Fuzzy Edges

DTF transfers use white ink behind the color so the design stays bright on dark shirts. That is a big part of why DTF looks so good.

But it also means messy artwork edges can show up more than people expect.

Soft edge pixels, glow effects, faded shadows, partially removed backgrounds, and blurry artwork can all create a faint white or gray halo around the design.

The easiest way to catch this is to place your artwork on a dark background in a photoshop type software before exporting. A design can look perfectly clean on a zoomed out screen while still hiding a fuzzy edge that becomes obvious when zoomed in.

This is where our side of the process matters too.

While our software is some of the best in the industry, it cannot fix everything, though. If a file already has blurry edges, leftover background pixels, or semi-transparent haze built into it, we can only do so much once it reaches print.

For a deeper explanation, read our guide to white outlines in DTF transfers.

Keep Your Artwork in RGB or CMYK

Do not convert your artwork before uploading.

We only use expanded color gamut CMYK+RGBO printers. That means you can leave your file in RGB or CMYK and upload it as-is,.

Expanded color gamut helps us keep colors richer and more vibrant for those RGB files without asking you to guess at CMYK conversions or print settings.

Your screen will not always match a printed shirt perfectly because screens use light and shirts use ink, and to top it off most screens aren't properly delta calibrated. But for most artwork, leaving your file as it was designed will result in a near perfect match when printed.

If you are printing a brand color, team color, or something that needs to be as accurate as possible, our DTF Color Chart is the best way to see actual pressed colors before committing to a larger run.

Keep Small Text and Thin Details Strong

DTF can print a lot of detail, but there are still practical limits.

Tiny text, super-thin lines, little distressed gaps, and small isolated dots can become hard to read or may not hold the way you expect once they are printed and pressed.

Before uploading, look at your design at the size you want it printed and ask yourself:

Can I still read the small text?
Are the thin lines strong enough?
Does the distressed texture still look intentional?
Are there tiny details that may disappear?

When in doubt, make the text a little bigger, thicken the line, simplify the detail, or just add an outline.

A small adjustment before printing is a lot better than getting a shirt back and realizing the little details got lost.

Be Careful With Fades, Glows, and Soft Effects

Gradients & detailed artwork can look amazing in DTF and we have the honor of printing it for our customers every day.

The thing that can cause problems with customers is soft transparency.

Glow effects, faded shadows, watercolor edges, and low-opacity details can look good on a screen but may act differently once white ink is printed behind them. Sometimes they can create a pale edge or hazy look that was not obvious in the original artwork. Our unique software helps with fading it as naturally as possible, but due to the nature of DTF it will never as good as other methods.

That does not mean you cannot use those effects. It just means they need to be built intentionally.

If your design depends heavily on soft fades, transparent edges, or glow effects, it is worth taking a closer look before ordering. Many times we end up recommending customers halftone the design to give the best results.

Gang Sheets Do Not Fix Bad Artwork

Gang sheets are one of the best ways to save money and keep your favorite designs ready to press, but our gang sheet file enhancer or background remover cannot improve the quality of a file as well as by doing it manually.

When building your gang sheet it is always best to:

Upload the best version of each design you have.
Set every design to the size you actually want it printed.
Remove any blank space around the design
Leave enough room between designs to cut them apart.
Do not make a small file huge.
Double-check your final counts before adding it to your cart.

Our Gang Sheet Builder lets you upload your designs, choose your sizes, and arrange everything in one place.

If you need help using it, our Gang Sheet Builder Tutorial walks you through the process.

AI Artwork, Canva Designs, and Mockups

AI artwork and Canva designs can be great starting points. We see plenty of good files made with both.

You just need to give them a quick look-over and edit before uploading.

Make sure you are sending the flat artwork file—not a mockup of the design on a shirt, a fake transparency checkerboard, or a low-resolution preview image.

With AI artwork, watch for:

Misspelled or warped text
Strange extra shapes
Fuzzy or unfinished edges
Missing details
Random artifacts in the design
Low-resolution exports
Backgrounds that were not fully removed

With Canva, make sure you export the final design at the size you need and choose a transparent background when your design does not need a box behind it.

Also, make sure you have the rights to use the artwork you upload. We cannot print trademarked or copyrighted designs without permission, including professional sports logos, Disney characters, fashion brands, or watermarked artwork.

Quick Checklist Before You Upload

Before you place your order, take a minute to make sure:

Your design is the size you want it printed.
Your artwork still looks sharp when you zoom in.
Your background is truly transparent.
There is no white, gray, or fuzzy fringe around the edges.
Small text is readable.
Thin lines are thick enough to hold.
You are uploading the original artwork file—not a screenshot or mockup..
Your gang-sheet designs are sized correctly and spaced for cutting.

What We Can Help With—and What We Cannot Fix

We can often help with things like background cleanup, basic resizing, vector redraws for simple logos, and cleaning up artwork that is close but not quite ready. If that is something you're needing assistance with please reach out to us at support@armorink.com before ordering.

But there are a few things no printer can magically fix:

A tiny screenshot stretched into a large back print
Artwork that is already blurry or heavily compressed
Text that is too small to read at the finished print size
Fine details that are too thin or delicate to hold up
A mockup photo instead of the actual design file

We would always rather catch that before we print than have you spend money on a transfer that does not turn out how you pictured it.

Need Help With Your Artwork?

We know not everyone is a graphic designer. That is completely okay.

We would rather help you catch an issue before we print than send you a transfer that does not turn out the way you hoped.

If you are unsure about a file, reach out before ordering. We can help point you in the right direction. If a design needs real cleanup, resizing, vector redraw work, or more involved editing, our artwork editing service is available to help get it ready for print.

A clean file from you and careful printing from us is how you get the best possible DTF transfer.
