Why This Screen

Saati Standard-T Mesh

Saatilene Hi-Tex standard-thread polyester — durable, tear-resistant, and holds high tension cycle after cycle.

230 Mesh — Fine Detail

A light ink deposit tuned for this count. Halftones, 4-color process, water-based.

Yellow anti-halation mesh

Dyed mesh absorbs stray UV during exposure to stop undercutting — sharper stencils and better detail hold.

Welded Aluminum Frame

Lightweight, warp- and corrosion-resistant, precision-welded to stay dimensionally stable on press.

Pre-Stretched & Ready

Professionally tensioned for consistent tension edge to edge — verify it with a tension meter.

Reusable

Reclaim and re-mesh at end of life — or use our remesh exchange program to keep good frames in service.

What You Get & What You Need

One 20″ x 24″ pre-stretched aluminum screen with 230 yellow Saati Standard-T mesh.

Degrease it, then coat with screen emulsion using a 16″ scoop coater.

Burn the stencil on an exposure unit (dyed mesh gives sharper, cleaner detail).

Set exposure with an exposure calculator — every light source, emulsion, and coating is different — and keep our emulsion troubleshooting guide handy for washout issues.

Check your tension with a tension meter — it’s how you confirm the screen is at proper, consistent tension (Newtons) before you coat and print.

Reclaim with screen chemicals, and pair with a squeegee up to 16″ from our squeegee lineup.

Why 230 Mesh?

Its fine, uniform openings reproduce halftone dots and thin lines cleanly with a light ink film — exactly what process and high-detail printing require. It’s the workhorse fine-detail count.

Getting Your Exposure Dialed In

There’s no universal exposure time. Your light source, emulsion, coating technique, and stencil thickness all change how long a screen needs — so the only reliable way to nail it is to shoot an exposure test with a calculator or step wedge. Run it once for your setup and you’ll have repeatable times for every screen after.

Chromaline Exposure CalculatorShoot one test to find the correct exposure time for your exact light source, emulsion, and coating.

Chromaline 10-Step Exposure GuideA 10-step wedge that brackets your exposure across a range — read the crispest step to set your time.

Screens not exposing or washing out right? Our Emulsion Troubleshooting Guide walks through underexposure, stencil breakdown, pinholes, and washout problems step by step.

Good To Know Before You Buy

Order two or more. Single frames can be damaged in transit and can’t be replaced. Order 2+ of the same size so we pack them securely mesh-to-mesh.

Dial in exposure. No universal time — light source, emulsion, coating, and thickness all change it, and dyed mesh can need a bit longer than white. Shoot an exposure calculator for your exact setup.

Set & check your tension. Use a tension meter to verify the screen is at proper, consistent tension before burning and printing — low or uneven tension causes registration and print-quality problems.

Degrease before first use. Even new mesh needs a degreaser before your first emulsion coat for proper stencil adhesion.

FREQUENTLY ASKED QUESTIONS

20″ x 24″ · 230 Yellow Mesh — Frequently Asked Questions

What is 230 mesh best for?

Its fine, uniform openings reproduce halftone dots and thin lines cleanly with a light ink film — exactly what process and high-detail printing require. It’s the workhorse fine-detail count. In short: halftones, 4-color process, water-based.

What is Saati Standard-T thread mesh?

Mesh is woven in three thread diameters: S (thin), T (standard/medium), and HD (heavy). This screen uses Saati’s Standard-T thread (Saatilene Hi-Tex) — the durable, high-tension workhorse for the vast majority of shop jobs. Thicker threads resist tearing and hold tension longer than thin S mesh.

Why is the mesh yellow?

Yellow dye absorbs stray UV during exposure to prevent undercutting — sharper stencils and better fine-detail hold. Because the dye also absorbs some UV, dyed mesh can need a somewhat longer exposure than white; the exact difference depends on your light source (often minor with a tuned LED unit), so run an exposure test.

How do I check my screen tension?

Use a tension meter. Rest it on the mesh and it reads the tension in Newtons (N/cm). It’s how you confirm a screen is at proper, consistent tension before coating and printing — correct, even tension gives better registration, cleaner ink release, and sharper prints, and helps you re-tension retensionable frames to spec.

What size scoop coater should I use?

A 16″ scoop coater is ideal for a 20″ x 24″ frame (roughly 4–5″ shorter than the frame’s short side so it clears the rails).

What emulsion should I use?

Any quality screen emulsion — dual-cure, photopolymer, or diazo. Degrease the mesh first, coat both sides, and dry flat in a dark cabinet before exposing on an exposure unit.

How do I find the correct exposure time?

There’s no one-size time — every light source, emulsion, coating technique, and stencil thickness exposes differently. Shoot an exposure calculator or 10-step exposure guide once for your setup and you’ll have repeatable times. If screens break down, wash out poorly, or won’t hold detail, see our emulsion troubleshooting guide.

Can I reuse the screen?

Yes. Reclaim the stencil with screen chemicals and re-coat. When the mesh wears out, re-mesh the frame or use our remesh exchange program.

Will 20″ x 24″ fit my equipment?

20″ x 24″ is a standard size that fits most manual and automatic presses, washout booths, and exposure units. Printable area is under 14″ x 18″.

Why do you recommend ordering two?

Single frames can be damaged during shipping and can’t be replaced. Ordering two or more of the same size lets us pack them securely mesh-to-mesh in transit.

What inks can I print with it?

Plastisol, water-based, and discharge inks all run on this screen — higher counts like this one favor fine detail, halftones, and thinner deposits.

Setting up your screen room?

We’ll help you match mesh, emulsion, scoop coater, exposure unit, and tension meter to your artwork and ink — message us on Tidio, email, or call.
