DTG printing, short for direct-to-garment printing, is one of the most straightforward ways to get a sharp, full-color design onto a shirt without the setup costs and minimums that traditional screen printing often requires. At R.J. Marx Custom Graphics, we use DTG as part of a broader range of printing and graphics services we’ve been proud to offer since 1967. If you’ve ever wondered exactly how a logo file becomes a finished, wearable shirt, here’s an honest walk-through of the process from start to finish.
It Starts with Your Artwork
The whole process lives or dies on the quality of the file you bring us. A high-resolution vector file or a high-quality PNG with a transparent background gives our graphic designers the cleanest starting point. Logos pulled from a website or a blurry photo from a phone will almost always need to be reworked before printing, and that takes extra time.
When customers in Appleton, Oshkosh, Neenah, and surrounding areas come to us with a new project, we walk through the artwork first. If your file needs cleanup, color adjustments, or a full rebuild, our team handles that before anything touches the printer. Getting the file right upfront is what separates a clean, professional result from something that looks washed out or soft once it’s on fabric.
Preparing the Garment
Once the artwork is approved, the shirt itself needs to be prepped. For DTG printing on dark or colored garments, this means applying a pretreatment solution to the fabric. The pretreatment helps the ink bond to the fibers properly so the colors stay vibrant after washing. The garment is then heat-pressed briefly to cure the pretreatment before it goes anywhere near the printer.
Fabric type matters here too. A 100% cotton shirt tends to hold DTG ink better than a heavy polyester blend. We’re straightforward with customers about what garments will give them the best results, whether they’re ordering a run of shirts for a Fond du Lac business, a community event in Green Bay, or a team in Neenah.
The Print Itself
The shirt is loaded flat onto the printer’s platen, which holds it perfectly still during the print. The DTG printer moves across the surface in passes, laying down water-based ink directly onto the fabric much like a high-precision inkjet printer would on paper. The colors are applied in layers, and the printer follows the artwork file exactly, reproducing gradients, fine lines, and photographic detail that would be nearly impossible to replicate with traditional screen printing at small quantities.
For light-colored garments, the process is fairly quick. Dark garments require an additional white ink underbase layer first, which the printer lays down before the color passes. This is what makes colors pop on a black or navy shirt rather than looking faded or muddy.
Curing and Finishing
After printing, the shirt goes through a commercial heat cure, usually in a conveyor dryer or a heat press. This step locks the ink into the fibers permanently. Skip it or rush it, and the print will crack or wash out quickly. Done properly, a DTG-printed design holds up well through regular washing, especially on quality cotton garments.
We inspect every shirt before it leaves our facility in Appleton. If something looks off, whether it’s a faint line, an uneven edge, or a spot where the ink didn’t bond correctly, we catch it here rather than letting it get to you.
When DTG Makes the Most Sense
DTG is a strong option for short runs, orders with lots of colors, or designs that include photo-realistic detail. It’s also great for one-off custom pieces. If you need a hundred identical shirts with a two-color logo, screen printing might actually be more cost-effective. We’re happy to talk through what makes sense for your specific project so you’re not paying more than you need to.
Customers across Appleton, Oshkosh, Green Bay, Fond du Lac, and surrounding areas trust us with everything from simple shirt orders to complex emergency vehicle graphics, and we bring the same attention to detail to every job regardless of size. That’s something we’ve carried forward through more than five decades in this business, and it’s not something we take lightly.
If you have a project in mind or just want to ask a few questions before committing, give us a call or drop us an email. We’re glad to help you figure out the best path from your logo file to a finished shirt you’ll actually be proud to wear.
