STARTING STRONG WITH A THICK, STABLE STENCIL
The foundation of a faux high-density print lies in creating a strong, thick stencil. Instead of traditional capillary film, which would normally be used to achieve the necessary depth, a high solids emulsion provides that extra thickness. High solids emulsion allows multiple coatings to build up depth, forming a stencil that can hold heavier layers of ink and maintain clean, dimensional lines.
In this setup, a 156 mesh screen serves as the underbase, while screens at around 200 and 250 microns handle the primary layers for adding texture. With a few coats applied and carefully exposed using an LED exposure system, this setup allows the stencil to hold ink in sharp, thick layers, providing the perfect starting point for a dimensional effect without specialized film.
THICKENING THE INK WITH FUMED SILICA AND PUFF ADDITIVE
For a high-density look, the ink mix needs to be thicker than usual. Instead of a standard consistency, which might spread too thinly or lose shape, adding fumed silica to the ink mix creates a denser, paste-like quality. This small amount of fumed silica (about 0.75% to 0.8% of the ink weight) stabilizes the ink and allows it to hold shape on the stencil.
To add even more depth, a puff additive goes into the mix, allowing the ink to slightly expand as it sets. Together, the fumed silica and puff additive create a consistency that mimics high-density ink without the need for specialized products, transforming standard ink into a thick, structured layer that won’t flatten out during the print.

LAYERING UP FOR TEXTURE AND HEIGHT
The process of layering the ink is where the high-density effect really starts to shine. Each pass of ink builds on the last, creating a dimensional design that stands out from the fabric. To avoid pressing the ink down too much, each pass is applied with just enough pressure to let it sit on top of the fabric rather than pressing into it.
An off-contact adjustment, achieved by placing a small spacer (like a coin) under the screen, helps the ink stay raised without smearing or losing shape. Between each layer, a quick flash cure sets the ink in place, creating a sturdy base for the next layer. This “print-flash-print” technique keeps the layers separated and prevents the ink from blending, preserving that raised effect.
ADDING CREATIVITY WITH COLOR AND LAYERS
Faux high-density printing opens up creative possibilities with color and layering combinations. A tone-on-tone effect, inspired by an Adidas hat with subtle color layering, shows how adding different tones can bring out the depth and details of a design. For a similar effect, a black underbase layer provides stability, with light blue ink layered on top and choked slightly to allow for expansion.
This approach allows for subtle or bold combinations, making each design dynamic depending on light and angle. High-density layering creates eye-catching contrasts and shadows, making even simple designs look and feel dimensional.

TAKEAWAYS FOR SUCCESS
Here are a few key tips for anyone interested in exploring faux high-density screen printing:
- Build a Thick Stencil: A thicker stencil layer, around 300 microns, adds sharper edges and more pronounced texture.
- Control Off-Contact: Using small spacers to adjust the off-contact distance keeps the ink raised and prevents smudging.
- Experiment with Color: Tone-on-tone or contrasting layers add an extra level of interest, letting the design stand out under different lighting.
By adjusting the emulsion, ink mix, and printing technique, faux high-density printing opens up a world of creative possibilities. This deep dive demonstrates how a few small tweaks to a standard setup can produce that professional, dimensional effect—without the need for expensive materials or equipment.
