Why Your Artwork Fails at Print Size (And How to Fix It)
The most common reason artwork breaks when scaled up for screen printing — and what to do when you only have a low-resolution file.
It happens constantly: a client sends a logo file that looks fine on screen, the artwork gets placed into the RIP at print size, and suddenly it's a blurry mess. The print can't go ahead. The deadline is tomorrow. The original designer is unreachable.
This is the most common situation we fix at SepArt Studio. Here's what's actually happening — and what the options are when you're stuck with a file that won't scale.
The Root Problem: Pixels Don't Stretch
Most artwork that "looks fine" on screen is a raster file — a JPEG, PNG, or embedded image made up of a fixed grid of pixels. At screen size (72–96 DPI), 400 pixels across a logo looks sharp enough. But print for garments typically requires 300 DPI or higher at the printed size.
If the logo is going on a shirt at 30 cm wide and you need 300 DPI to print cleanly, you need 3,543 pixels of image data. If the file you have is 400 pixels wide, it will be stretched to 9x its original size. Every pixel becomes a blurry block.
The printer can't manufacture detail that isn't in the file. They can only work with what's there.
Why Vector Files Don't Have This Problem
Vector artwork is defined by mathematics, not pixels. A logo stored as curves and shapes in an AI or EPS file can be scaled to any size — a business card or a billboard — and every edge stays perfectly sharp. There are no pixels to stretch.
The problem is that most clients don't have the original vector. The logo was built years ago, the designer is gone, or it was only ever supplied as a JPEG from an email thread. This is where artwork rebuild becomes necessary.
What Artwork Rebuild Actually Involves
When we rebuild low-resolution artwork, we're not "upsizing" the file — we're redrawing it. We trace and reconstruct every element as clean vector paths and shapes, working from the raster reference as a visual guide.
The rebuilt file is a brand-new vector — not a processed version of the original. Edges are clean, colours are correctly defined, and the file can be placed at any size without quality loss.
Depending on the complexity of the artwork, a rebuild can take 1–4 hours. Simple text logos with a couple of shapes are at the faster end. Complex illustrations with multiple elements and fine detail take longer.
When Rebuilding Isn't Possible — Or Isn't Necessary
There are situations where a full vector rebuild isn't the right solution:
When the artwork is photographic or complex raster. If you're printing a photograph of a person or a detailed illustration that was created as pixel art, vectorising it isn't the right approach — you'd be converting a raster image into a flat, illustrated style. Simulated process separation working from the raster is the correct path.
When the raster resolution is actually sufficient. 300 DPI at print size isn't always required. For certain DTF and DTG processes with lower halftone frequencies, artwork at 150–200 DPI can still produce acceptable output. We'll tell you if your file is workable as-is.
When you can get the original source file. If the original designer is contactable, ask for the native Illustrator or EPS file. A few hours of effort tracking it down is cheaper than a rebuild.
Common File Situations We Handle
"I only have the logo from the website." Website logos are commonly 72–150 DPI and 200–500 pixels wide. Almost always needs a rebuild for garment print.
"The EPS won't open / prints blank." Corrupt EPS files are more common than you'd think — especially older files created in legacy software. We can often recover and reconstruct these.
"I have a PDF but it's flattened." PDFs can contain vector data (good) or flattened raster (bad). We'll open it and tell you which yours is. If it's vector, it may be usable. If it's raster, it needs a rebuild.
"The artwork is a scan of a printed garment." Photographs of printed shirts come with distortion, colour contamination from the fabric, and loss of registration between layers. These need a full rebuild — but it's doable. A flat-laid scan under even white lighting gives the best result.
What to Send Us
When you're not sure whether your file will work for print, just send it over through the quote form with a note about the print size and process. We review every file before quoting and will tell you exactly what it needs and what it will cost. No commitment required to get that answer.
Most file problems are solvable. The cost of fixing them before you burn screens is always less than fixing them after.
