Screen clean spray KIWO

Q: Is Pregan 235s safe for photoemulsions?

Yes. Pregan 235s is formulated with a balanced pH to have minimal attack on photoemulsions. It dissolves dried ink in the mesh without damaging the stencil layer.

Q: Can I use Pregan 235s with water-based or plastisol inks?

No. Pregan 235s is for solvent-based inks only. Use a water-based screen cleaner for water-based inks and a plastisol ink wash for plastisol.

Q: Does Pregan 235s replace emulsion remover?

No. Pregan 235s clears ink from the mesh during production while keeping emulsion intact. Emulsion remover (Autostrip) removes the entire stencil to reclaim the screen. Both are needed for a complete screen maintenance workflow.

Q: How far should I spray Pregan 235s from the mesh?

Spray from 20–30 cm distance for even, controlled application. Too close over-saturates; too far reduces effectiveness.

When and How to Use Pregan 235s

Use Pregan 235s during production when mesh begins to clog or after any printing pause that risks ink drying in the mesh. It is not a screen reclaiming product — it's a production maintenance tool that keeps your screens printing cleanly without stopping the run.

Shake the can well before use
Spray from 20–30 cm distance onto the clogged area
Allow to act for 30–60 seconds
Wipe clean with a lint-free cloth or continue printing

Ideal Applications

Professional screen printing shops with solvent-based ink production
Daily screen cleaning and maintenance during production
UV and solvent ink removal during printing pauses
Preventive maintenance between print jobs
Quick spot-cleaning of clogged mesh areas without full reclaiming

Important: Pregan 235s is for solvent-based inks only. For water-based or plastisol ink removal, use appropriate water-based screen cleaners. Use in ventilated areas. Avoid skin contact. Keep away from heat sources.

Frequently asked questions — KIWO Pregan 235s Screen Opener Spray

What is a screen opener spray and when do I need it?

A screen opener spray dissolves dried ink residues that clog mesh during printing — without requiring you to remove and reclaim the screen. You need it when fine details stop printing cleanly, during production pauses, or when solvent-based ink starts drying in the mesh. It keeps production running without interruption.

Is Pregan 235s safe for photoemulsions?

Yes. Pregan 235s is specifically formulated with a balanced pH to have minimal attack on photoemulsions. Unlike general solvents, it dissolves dried ink residues in the mesh without stripping or damaging the stencil layer — which is why it's designed for use during printing, not just for final cleanup.

Can I use Pregan 235s with water-based or plastisol inks?

No. Pregan 235s is formulated specifically for solvent-based inks. For water-based inks use a water-based screen cleaner; for plastisol inks use a plastisol-specific ink wash. Using the wrong cleaner will not be effective and may damage the stencil.

Does Pregan 235s replace emulsion remover (screen stripper)?

No. These are two different products with different purposes. Pregan 235s clears ink from the mesh during production while keeping the emulsion intact. Emulsion remover (like Autostrip) removes the entire emulsion to reclaim and re-coat the screen with a new stencil. Use both — Pregan 235s during the print run, emulsion remover when you're ready to change designs.

How far should I spray Pregan 235s from the mesh?

Spray from 20–30 cm distance. Spraying too close concentrates the solvent in one area and may over-saturate the mesh; too far reduces effectiveness. The aerosol is designed to deliver an even, controlled mist at this distance.
