$Matsui Soft Tex Overprint 680$

Matsui Soft-Tex Overprint 680 (WS0546) is a specialty top-coating binder that transforms any water-based screen print into a silicone-like printing surface with an exceptionally soft, smooth hand feel. Applied as the FINAL print station over your cured or flashed color layers, Overprint 680 encapsulates the print beneath it and converts the surface texture to a premium silicone-like tactile quality — regardless of what base or white was used underneath. Prints through 135 mesh/inch. Works over any Matsui acrylic or polyurethane ink system — including all Matsui bases, whites, and colors. The fastest way to add a silicone-like finish to prints that were not made with a silicone-finish base. Free from formalin, organotin, and other endocrine-disrupting substances. Can be dry cleaned and ironed. Enhance open time with Thickener B (0.25-1%) if needed. Requires zero viscosity modifications. Cures at 320°F (160°C) for 3 minutes. PVC-free. Environmentally safe.

Description

Matsui Soft-Tex Overprint 680 — Add Silicone Feel to Any Print

Custom color work gets the client in the door. Hand feel closes the job. Shops can build the right color, print clean detail, and cure the garment perfectly—but if the customer wants that smooth silicone-like finish and the print was built with a base that does not naturally produce it, the job still feels incomplete.

That is where Soft-Tex Overprint 680 fits.

Overprint 680 is not a mixing base and it is not a pigment carrier. It is a clear top-coating binder printed as the final station over your already-printed and flashed color layers. Its job is to encapsulate the surface of the print and transform the final tactile feel into a smooth, soft, silicone-like finish.

This gives shops a way to add silicone feel to an existing Matsui print without reformulating the entire ink system. Printed with 301C Clear plus Neo Pigments on cotton and the client now wants a silicone-like finish? Print Overprint 680 on top. Printed with Stretch Mat on Dri-Fit and want a more premium surface? Print Overprint 680 on top. Printed with Soft-Tex White 350 and want to enhance the silicone surface even further? Print Overprint 680 on top.

The application is simple: print your design, flash as needed, then print Overprint 680 through a 135 mesh screen as the last station. Cure at 320°F (160°C) for 3 minutes. The result is a smooth silicone-like surface over your existing print.

Think of it as a finish upgrade. Bases like Stretch Clear and Acrylicon Clear have silicone-like properties built into the base itself. Overprint 680 lets you add that style of finish to prints made with bases that do not have it built in—or intensify the finish of prints that already do.

How Soft-Tex Overprint 680 Works with Matsui Prints

Overprint 680 works differently from the Matsui bases and extenders you mix pigments into. It is a final-surface product. The workflow is simple:

Print your design first. Use your chosen Matsui base such as 301C Clear, 301M Matte, Stretch Clear, EasyPrint Clear, Simple Clear, Soft-Tex Clear 350, or another Matsui print system underneath.

Flash between color layers as needed. Build the design exactly as you normally would during production.

Print Overprint 680 last. Set up a dedicated screen and print Overprint 680 through 135 mesh over the full printed area as the final station.

Cure completely. Cure at 320°F (160°C) for 3 minutes so the overprint layer forms a smooth silicone-like finish across the print surface.

That is the core advantage of Overprint 680: one extra screen, one extra station, and the full print surface gets upgraded to a premium hand feel.

How Soft-Tex Overprint 680 Fits with Matsui Bases, Clears, and Extenders

Matsui makes multiple base systems for different substrates, mesh ranges, opacity needs, and finish targets. In most cases, the base determines the substrate behavior and hand feel, the pigments determine the color, and the additives optimize the process. Overprint 680 sits above that system as a finish layer.

That makes it unique.

301C Clear, 301M Matte, EasyPrint Clear, EasyPrint Mat, Stretch Clear, Stretch Mat, Soft Stretch Clear, Acrylicon Clear, Simple Clear, and Extender Base are all part of the print build itself. Overprint 680 is the final tactile conversion layer that sits on top of the print. :contentReference[oaicite:1]{index=1}

That means shops can keep using the base that makes sense for the substrate and mesh, then use Overprint 680 when they want to standardize or upgrade the final surface feel.

Soft-Tex Overprint 680 vs. Acrylicon Clear vs. Stretch Clear

Spec	Soft-Tex Overprint 680	Acrylicon Clear	Stretch Clear
Role in Print	Top coat / final station	Mixing base	Mixing base
Used With Pigments?	No	Yes	Yes
Main Benefit	Adds silicone feel after printing	Matte, zero-tack silicone-like finish built in	Stretch-rated clear with silicone-like finish
Best Substrates	Any already-printed Matsui design	Performance and high-stretch synthetics	Performance fabrics and Dri-Fit
When to Choose	When the print is already built and you want to upgrade the surface	When you want premium matte silicone-like custom colors from the start	When you want stretch-friendly custom colors from the start

The bottom line: Acrylicon Clear and Stretch Clear are base-selection decisions made at the beginning of the job. Overprint 680 is the finish decision you make at the end.

How Matsui Additives Fit into Production with Overprint 680

Overprint 680 is ready to print from the container and usually does not need modification. The only common direct adjustment is Thickener B at 0.25-1% if you need more body for a specific screen setup or application style.

The more important additive conversation is usually about the print layers underneath.

The problem: water-based colors underneath are drying in the screen during long runs or production pauses. The additive solution: Retarder MG helps extend open time.

The problem: the print build underneath needs better wash durability. The additive solution: Fixer WF-N improves wash fastness on acrylic Matsui systems. On 350 polyurethane systems, use the chemistry intended for that family instead. The 301C comparison section specifically notes that the polyurethane 350 Series uses Fixer V instead of Fixer WF-N. :contentReference[oaicite:2]{index=2}

The problem: the print needs better penetration and softer bonding into the garment. The additive solution: Softener MG.

The problem: you want a simplified all-in-one approach for the color system underneath. The additive solution: Quick Additive.

Why Screen Printers Choose Soft-Tex Overprint 680

“My client wants silicone feel on a cotton print that was built with 301C.” This is the core Overprint 680 use case. The color is right. The print is already working. You just need the surface to feel more premium. Overprint 680 gives you that upgrade without rebuilding the ink system.

“I print with multiple Matsui bases and want one product that can standardize the final feel.” Overprint 680 works over acrylic and polyurethane Matsui systems, making it useful across cotton work, performance work, and mixed builds.

“I want to push the finish even further on already premium prints.” Even if the base underneath already has silicone-like characteristics, Overprint 680 can intensify the smoothness and unify the tactile finish across the full print area.

“I need to eliminate slight tack and leave a cleaner cured surface.” Overprint 680 is designed to leave a smoother, more premium top finish.

Soft-Tex Overprint 680 is a clear top-coating binder printed as the final station over your existing water-based print to create a smooth silicone-like surface and softer hand feel.

Is Overprint 680 a mixing base?

No. It is not a mixing base and should not be mixed with pigments. It is printed over finished color layers as a top coat.

Can I print it over Matsui acrylic and polyurethane systems?

Yes. It works over Matsui acrylic bases, polyurethane 350 Series products, Matsui whites, and prints made with Matsui pigment systems underneath.

What mesh should I use for Overprint 680?

The recommended mesh is 135/inch.

How do I cure Soft-Tex Overprint 680?

Cure at 320°F (160°C) for 3 minutes.

Can I use it on cotton prints?

Yes. One of its best use cases is adding silicone-like feel to cotton prints made with bases like 301C Clear or 301M Matte that do not have that finish built in.

Will it change the color of the print?

No. It is a clear overprint intended to change the surface feel, not the color underneath.

Can it help reduce residual tack on the print surface?

Yes. It is designed to leave a smoother, more premium cured surface with a silicone-like feel.

What additive can I use if I need to thicken it?

Thickener B at 0.25-1% can be used if you need more viscosity.
