Technical Tuesday-Don’t Fear the Re-Up: Why Switching Emulsions is Way Easier Than You Think


The Why: Break Out of Your Emulsion Comfort Zone

If you’ve ever stayed loyal to a hard-to-find or overpriced emulsion just because "it’s what we’ve always used," you aren’t alone. Many print shops fall into a comfort trap, terrified that switching emulsion will derail production with hours of exposure testing, screen breakdown, or endless pinholes.

Here’s the reality check: Most modern emulsions are built on very similar chemical foundations. Whether you are running a photopolymer, a dual-cure, or a diazo-based formula, today's products are engineered to be forgiving and consistent. There’s no “premium” emulsion. Holding onto a expensive brand out of fear is simply leaving money on the table. Switching to a cost-effective, readily available emulsion is a low-risk move that can save your shop real dollars annually without sacrificing print quality.

The How: The 3 Core Variables to Match

When looking for a new, budget-friendly emulsion, you don't need to reinvent the wheel. You just need to focus on matching or adjusting three basic variables:

  1. Solids Percentage: This dictates how much emulsion remains on the screen after drying. Higher solids (40–50%) mean a thicker stencil profile (EOM) with fewer coats, perfect for laying down heavy deposits like white ink on dark fleece. Lower solids (30–40%) yield thinner coatings ideal for fine detail and high mesh counts. Match the solids percentage to your daily shop needs.
  2. Exposure Time: Exposure speed is primarily determined by the sensitizer technology (pure photopolymers expose in a fraction of the time compared to dual-cure or diazo formulas). Switching between types isn't hard, it just requires dialing in a new baseline using a 21-step grayscale or exposure calculator.
  3. Reclaimability: A great emulsion should hold up on press against your ink system (plastisol, water-based, or discharge) while breaking down smoothly in the reclaim booth. You want a stencil that resists press friction but doesn’t require an act of congress to wash out with standard chemical reclaimers.

Dialing It In: Dialed in 2 to 3 Screens Max

The biggest excuse for not switching is the fear of wasted time spent testing. But getting a new emulsion running perfectly doesn't take days or even hours—it takes 2 to 3 screens max.

With an expert in your corner, we can run a quick step-exposure test, evaluate your coating technique, check the moisture content, and lock in your exact exposure times in less than an hour.

The Result: Lower Costs, Zero Downtime

When you make the switch with proper setup support:

  • Cost Savings: Transition immediately from an expensive, supply-chain-plagued product to an affordable, readily stocked alternative.

  • Consistent Quality: Maintain sharp line definition, optimal stencil thickness, and painless reclaim cycles.

  • Peace of Mind: Gain complete confidence in your pre-press workflow knowing your exposure times are scientifically locked in.

Stop letting fear dictate your shop's profit margins. Don’t allow employees unnecessary resistance to change hold back saving money in this time when we all need to. Ready to drop your screen-making costs without losing a minute of production? Reach out today for a consultation, I’ll come in, get your new emulsion set up on 2 to 3 screens, and have your shop fully transitioned in under an hour!
