Graphic and sign shops run UV-cured and solvent-based inks, not plastisol, and that changes what your screen room actually needs. Standard garment screen cleaning chemistry is built around plastisol and water-based inks, so it often falls short on rigid-substrate work. Here is what to look for instead, and why it matters.

WHY GRAPHIC AND SIGN PRINTING CHEMISTRY ISN'T THE SAME AS TEXTILE CHEMISTRY
Most screen cleaning chemistry on the market is built with garment printers in mind, and that is a problem if your shop runs a different kind of job entirely.
- Ink systems: UV-cured and solvent-based inks behave nothing like plastisol or water-based textile inks.
- Cure behavior: UV inks cure instantly under light rather than heat, which means they stay "wet" on the screen longer than a garment printer would expect.
- Substrate differences: signage, acrylic, and coroplast are rigid substrates, not fabric, and that changes how ink sits on the mesh and how it needs to come off.
WHAT MAKES UV AND SOLVENT INKS HARDER TO CLEAN
On the production floor, this shows up as reburns, color-change contamination, and ghosting on reused screens.
- UV ink does not dry the way plastisol does, so a rushed color change can carry contamination into the next run.
- Solvent ink residue can affect adhesion on the next job if a screen is not fully clean before it goes back into rotation.
- Incomplete cleaning does not always show up to the naked eye. It often only becomes obvious under UV light inspection, after the job is already running.
SIGNS YOUR CURRENT CHEMISTRY ISN'T BUILT FOR GRAPHIC PRINTING
- Reburns happening on more than 1 in 20 screens
- Screens ghosting or showing image bleed-through after reclaiming
- Your current supplier cannot answer straightforward questions about UV or solvent ink compatibility
WHAT TO LOOK FOR IN SCREEN CLEANING CHEMISTRY FOR SIGN & GRAPHIC SHOPS
If you are sourcing sign shop supplies and screen printing chemicals for the first time, or reconsidering what you have always used, a few things matter more than brand name:
- Proven compatibility with UV and solvent ink systems, not just plastisol
- Mesh-safe formulas that will not degrade fine mesh over repeated reclaims
- Consistent results regardless of which employee is running the screen room
- Low-VOC formulation, since compliance requirements keep tightening
HOW EASIWAY'S CHEMISTRY FITS GRAPHIC AND SIGN SHOP WORKFLOWS
Easiway works across ink systems, not just one. That means a single supplier instead of piecing together products from multiple vendors, dip tank compatibility for shops that want it, and a sample matched to your actual ink setup before you commit to switching.
KEY TAKEAWAYS
- Graphic and sign shops run different ink systems than garment shops, so screen cleaning chemistry needs differ too.
- UV and solvent inks create contamination and reburn risks that garment-focused chemistry is not built to solve.
- The right chemistry should be proven on UV and solvent inks, mesh-safe, and consistent across your whole team.
FREQUENTLY ASKED QUESTIONS
Can I use the same screen cleaning chemicals for garment and sign printing?
Not reliably. UV and solvent inks behave differently on screen than plastisol, and using garment-formulated chemistry can leave residue or damage mesh.
What ink types need special reclaiming chemistry?
UV-cured, solvent-based, and specialty coatings used on rigid substrates all require chemistry built for those specific ink systems.
How do I know if my chemistry is damaging my screens?
Watch for shortened screen life, ghosting after reclaiming, or mesh that feels thinner or weaker over time.
NEXT STEPS
If your screen room is still running garment-first chemistry on UV or solvent ink jobs, it may be costing you more reburns and rework than you realize. Shop Easiway chemicals and request a sample matched to your actual ink system before you switch anything.
