Standard plastisol in a flat color is where most custom screen printing jobs start and end, and for good reason. It's consistent, it's durable, and it works on everything. But there's an entire catalog of specialty inks that most people ordering custom shirts don't know exist. These aren't gimmicks. They're real ink systems that change the texture, reflectivity, or behavior of a print in ways that flat color can't. Some of them are worth the upcharge on the right project. Some of them aren't. Here's how each one works, what it looks like on a finished garment, and what you give up to get it.

Puff Ink

Puff ink contains a chemical foaming agent that expands when it hits curing temperature. The ink literally rises off the fabric during the dryer pass, turning a flat print into something with physical height. The finished texture is soft and rounded, almost foam-like. It works best on bold type and simple shapes because fine detail gets lost when the ink expands. Thin lines and small text will bloat and blur together.

The height you get depends on the mesh count, the ink deposit, and how hot the dryer runs. A lower mesh like a 60 or 86 puts down a thicker layer, which means more dramatic puff. Higher mesh gives a subtler raise. Most puff prints end up around 1 to 2 millimeters above the fabric surface. It's a classic look that's been around for decades, popular in '80s and '90s sportswear, and it's made a big comeback in streetwear and custom brand merch over the last few years. It's also one of the cheaper specialty effects since the ink itself isn't expensive and it doesn't require extra passes or secondary processes. You can see some puff ink work in our project gallery.

High Density Printing

High density printing builds ink up vertically to create a raised, rigid print with sharp edges. Where puff is soft and rounded, high density is flat on top with steep sidewalls. Think of the rubber badge on the chest of a Nike Dri-FIT shirt. That molded, structured look is what high density is going for.

Getting there takes work. It requires special thick-deposit screens, usually with a heavy emulsion buildup or capillary film to create a deeper stencil well. The ink gets laid down in multiple passes and flashes to stack layers. A good high density print might be 1 to 3 millimeters tall with crisp 90-degree edges. It adds real weight and dimension to a logo and feels premium when you touch it. The cost is production speed. Each piece takes longer on press because of the multiple print-flash cycles, and the design has to be relatively simple. Thin lines and tight registration between colors aren't realistic at that ink thickness. Stick to single-color logos, wordmarks, and bold graphic elements. If you're building custom branded merchandise for a retail line or a business that wants a premium look, high density is one of the strongest options available.

Suede Ink

Suede ink is one of the less talked about specialty effects and it's one of the most interesting to actually touch. It cures to a soft, velvety matte finish that feels like brushed fabric instead of ink. Run your fingers across it and the texture is genuinely different from any other print method. It's not raised like puff or rigid like high density. It sits close to the garment surface but changes the feel of the printed area completely.

It works well for larger print areas where texture matters more than detail. A big chest logo or a full-back graphic in suede ink turns the printed area into something people want to touch. It reads as upscale because the finish is unusual and clearly not a standard print. On dark garments, suede white has a chalky, matte look that's become popular in premium streetwear. The ink is more expensive per gallon than standard plastisol and it requires some dial-in on press to get the texture right, but it's a single-pass print with no secondary process, which keeps the overall job cost reasonable.

Metallic Ink

Metallic inks contain fine aluminum or polyester flake suspended in a plastisol base. When the ink cures, those particles settle flat and reflect light, creating a brushed-metal sheen. Gold, silver, and copper are the most common, but you can mix metallic base into other colors for a more subtle shimmer effect. A navy blue with metallic additive, for example, catches light without being overtly flashy.

The finish depends on the particle size and the amount of additive in the mix. A heavy metallic base produces a strong reflective effect. A lighter mix gives a softer sheen that only shows at certain angles. Metallics print well through standard mesh counts and don't require any secondary process, so they're one of the easier specialty inks to run in production. They're not as reflective as foil, but they're far more durable in the wash because the reflective particles are embedded in the ink film rather than bonded to the surface. After 50 washes, metallic ink still has its sheen. Foil won't. Metallic gold on a black Comfort Colors 1717 is one of the best-looking combinations we print.

Glitter Ink

Glitter ink works on the same principle as metallic but with larger flake. The particles are big enough to see individually, and they refract light instead of just reflecting it. The result is an obvious sparkle effect that's visible from across a room. It's a clear or tinted gel base loaded with flake, and it requires a lower mesh count screen to let the particles pass through without clogging. A 40 or 60 mesh is typical, which means the ink deposit is heavy and the finished print has real texture to it.

Glitter prints are rough to the touch and they're not subtle. That's the point. They work for event merch, spirit wear, dance and cheer apparel, anything where the goal is to be seen. The limitation is detail. You're printing through a very open mesh, so fine lines and small text won't hold. Keep the design simple and let the flake do the work. Durability is decent but not bulletproof. Some flake will shed over time with washing, though the print itself stays intact. If longevity is critical, metallic is the more practical choice. If impact is the priority, glitter wins.

Foil Printing

Foil printing is a two-step process. First, the design gets printed on the garment using a heat-activated adhesive. Then a sheet of foil, usually metallic gold, silver, or holographic, gets laid over the adhesive area and pressed with heat. The foil bonds to the adhesive and peels away clean everywhere else, leaving a mirror-finish version of the design on the fabric.

The result is the most reflective effect available in screen printing. A gold foil print catches light like actual metal, which is something no liquid ink can replicate. It looks incredible on black and dark-colored garments. The downside is durability. Foil is a surface bond, not an ink-in-fabric bond, and it will micro-fracture over repeated washing and wearing. The adhesive layer underneath matters a lot here. If the adhesive is printed in a color that matches the foil, small areas where foil lifts will show the tinted adhesive instead of bare fabric, which keeps the design readable longer. Foil is best used on pieces that won't be washed constantly, like retail display merch, limited runs, or event pieces where the visual impact matters more than a 200-wash lifespan.

Glow-in-the-Dark Ink

Glow ink contains phosphorescent pigment that absorbs light and re-emits it in the dark. The standard glow color is a pale green that looks almost white or slightly yellow-green in normal light, then glows bright green once the lights go out. Blue glow pigments exist too, though they tend to be dimmer and more expensive.

The glow effect depends on the ink deposit. Thicker layers absorb more light and glow brighter. A print through an 86 mesh will significantly outperform the same design through a 160 mesh. This means glow ink is at its strongest on bold graphics with solid fill areas. Fine detail prints thin, charges less, and barely glows. The ink itself is thick and gritty because of the phosphorescent particles, so it has a noticeable texture on the garment even in daylight. After a full charge from direct light, most glow prints stay visible for 15 to 30 minutes in complete darkness, then gradually fade. It's a natural fit for concert merch, nightlife brands, Halloween events, and anything tied to an after-dark setting.

Reflective Ink

Reflective ink is loaded with glass microspheres that bounce light directly back to its source. In normal lighting it looks like a slightly textured gray or silver print, nothing special. Hit it with direct light, like a camera flash or car headlights, and the entire printed area lights up bright white. It's the same retroreflective technology used in road signs and safety vests.

This one has real functional applications beyond just looking cool. Running clubs, cycling teams, and fitness brands use it for visibility on early morning or evening gear. Construction and roofing crews use it on custom workwear for job site visibility without wearing a full safety vest. It also works well as an accent effect. A small reflective logo on a dark hoodie sleeve is subtle during the day and shows up hard in flash photography, which makes it popular for brands that want their merch to perform in nightlife and event settings where people are taking photos. The ink requires a lower mesh count to get enough glass bead into the deposit, and the reflective performance is directly tied to how thick the print is. Like glow, keep the design simple and give the ink room to work.

Choosing the Right Effect for Your Project

Every specialty ink has a tradeoff. Puff and high density sacrifice fine detail for dimension. Glitter and glow sacrifice smooth texture for visual impact. Foil sacrifices wash durability for reflectivity. The question isn't which effect is the coolest. It's which effect serves the project. A brewery releasing a limited-edition shirt might go foil because the short-run nature means wash durability matters less than shelf appeal. A gym printing staff shirts might go reflective because their trainers work early mornings outdoors. A streetwear brand building a premium line might use suede or high density because the tactile quality justifies a higher retail price.

Most of these effects add cost because they require specialty ink, modified screen setups, or secondary processes. But on the right project, they're what turns a custom shirt from something people shove in a drawer into something they show their friends. We print all of these effects in-house for businesses, brands, and organizations across Richmond and Hampton Roads.
