Plastisol Ink

Professional Plastisol Ink for Manual and Automatic Screen Printing

Plastisol ink remains a dependable choice for garment screen printing because it combines strong opacity, vibrant color and production-friendly press performance. Kolormatrix carries professional plastisol ink for spot-color printing, polyester garments, low-temperature curing, simulated process, four-color process, specialty effects and custom color mixing.

Choosing the right ink involves more than finding the correct color. The garment fabric, dye stability, artwork, mesh count, press type, flash sequence and dryer performance all affect which plastisol system will produce the best result.

Choose Plastisol Ink by Garment and Production Need

High-Opacity White Plastisol Ink

White ink is one of the hardest-working products in a screen-printing shop. It may be used as a stand-alone print, an underbase beneath other colors or part of a detailed simulated-process image.

A good production white must balance several characteristics:

• Opacity on dark garments
• Printability through the selected mesh
• Mat-down performance over garment fibers
• Flash speed
• Wet-on-wet performance
• Build-up resistance during longer runs
• Complete curing at the manufacturer’s specified temperature

The thickest or most opaque white is not automatically the best choice for every shop. Manual printers may prefer an ink that clears the screen with less effort, while automatic shops may prioritize fast flashing, wet-on-wet performance and reduced buildup during long production runs.

Standard and High-Opacity Plastisol Colors

Ready-to-use plastisol colors are practical for spot-color artwork, school and team printing, branded apparel, promotional garments and everyday production.

Standard production colors may work well on light garments or over a white underbase. Super-opaque colors can provide additional coverage where the color is printed directly onto dark fabric or where greater opacity is required.

Opacity is influenced by more than the ink formula. Mesh count, stencil thickness, squeegee profile, pressure, print speed and garment texture all affect the final ink deposit.

Low-Cure and Low-Bleed Plastisol Ink

Polyester, sublimated fabrics and performance garments can release dye when exposed to heat. That dye may migrate through the printed ink and change the finished color—especially white or light-colored prints.

Low-cure and low-bleed inks are designed to help reduce this risk, but the terms do not mean exactly the same thing:

• Low-cure ink is formulated to reach a complete cure at a lower temperature than a conventional system.
• Low-bleed ink contains chemistry intended to resist dye migration from the garment.
• Low-cure, low-bleed ink combines both approaches for greater protection on many polyester garments.

No ink can guarantee that every polyester garment will remain stable. Test the actual garment before production because dye migration can vary by manufacturer, color, fabric construction and dye lot.

Barrier Gray for Difficult Polyester and Sublimated Garments

When a high-value or heavily sublimated garment presents an elevated bleed risk, a barrier-gray underbase can provide another layer of protection between the fabric dye and the printed colors.

A barrier underbase may be used beneath a compatible polyester white, followed by the top colors. This creates multiple layers of bleed resistance, but each layer adds ink deposit, flashing and production time. Test the complete print sequence for adhesion, cure, stretch, hand feel and dye migration before printing the order.

Black Plastisol Ink

Black plastisol is used for outlines, spot-color graphics, halftones, simulated-process shadows and artwork printed on light garments. Depending on the application, a shop may prefer a creamy production black, a matte black or a formulation optimized for fine detail and process work.

A black ink printed on a light garment may require less deposit than an opaque color printed on dark fabric. Use the mesh and stencil that provide the necessary coverage without adding unnecessary thickness.

Plastisol Ink for Advanced Printing

Simulated-Process Plastisol Ink

Simulated-process printing uses a carefully separated set of spot colors, halftones and controlled ink deposits to reproduce photographic or highly detailed artwork—often on dark garments.

Professional simulated-process results depend on the entire production system:

• Accurate color separations
• Dense, properly registered film positives
• Consistent screens and stencil thickness
• Correct mesh selection
• A controlled white underbase
• Compatible ink colors
• Stable press registration
• Managed flash temperatures
• Consistent squeegee pressure and speed

Ink alone cannot correct weak separations, inaccurate films or inconsistent screens. Great simulated-process printing begins before the job reaches the press.

Four-Color Process Plastisol Ink

Four-color process printing uses transparent cyan, magenta, yellow and black inks to reproduce a range of colors through halftone overlap. These inks are intentionally more transparent than standard spot colors.

Four-color process is normally printed on white garments or over a controlled white base using process-specific separations, screen angles, mesh counts and production settings. Standard opaque spot-color inks should not be substituted for a true process set.

Fluorescent, Metallic, Puff and Specialty Ink

Specialty plastisol inks can add brightness, texture, dimension or reflective effects to apparel. Available options may include:

• Fluorescent and neon colors
• Metallic ink
• Puff effects
• Specialty bases and additives
• Hot-split transfer products

Specialty inks often require specific mesh counts, stencil thicknesses, cure conditions or print techniques. Review the individual product instructions and test the effect before committing to production.

Plastisol Color-Mixing Systems

A professional mixing system allows a shop to create custom colors from a controlled group of components. This can reduce excess inventory and make approved colors easier to reproduce.

For better repeatability:

• Use an accurate gram scale
• Follow the formula by weight
• Use clean containers and mixing tools
• Record every adjustment
• Mix enough ink for the order and expected spoilage
• Print the approval sample using the intended mesh, underbase and garment
• Evaluate color under controlled lighting
• Save the final formula with the customer and job information

The appearance of a mixed color can change with the garment, underbase, mesh, ink deposit and curing conditions. A formula is only one part of producing a repeatable press match.

If mixing custom colors is consuming too much production time, Kolormatrix also offers professional ink color-matching services.

Bases, Reducers and Additives

Reducers, stretch additives, puff additives, mixing bases and other modifiers can change the way an ink prints or performs. They should be measured carefully and used according to the ink manufacturer’s recommendations.

Adding too much reducer or an incompatible modifier may affect:

• Opacity
• Bleed resistance
• Flash characteristics
• Cure requirements
• Stretch and durability
• Finished color
• Ink-film strength

Do not add reducer simply because an ink feels thick in the container. Plastisol is shear-thinning and often becomes easier to print after it has been properly mixed and worked on the press.

Flash Only as Much as Necessary

Flash curing should normally gel the surface of the ink enough to support the next color—not completely cure every layer before the garment reaches the dryer.

Excessive flash temperature or dwell time can contribute to:

• Rough or textured underbases
• Poor intercoat adhesion
• Distorted top colors
• Ink sticking to the back of screens
• Garment shrinkage
• Dye migration
• Reduced production speed

Allow the garment to cool before printing over the flashed underbase. Manual presses use multiple pallets partly to provide cooldown time. Automatic shops may use open stations, cooling fans or controlled press speed to manage platen and garment temperature.

Complete Cure Is Essential

Plastisol does not dry through air exposure. The complete ink film must reach the cure conditions specified by its manufacturer.

A print may feel dry on the surface while the lower portion of the ink deposit remains undercured. This can lead to cracking, poor stretch, ink loss and premature wash failure.

For reliable production:

• Measure the temperature of the ink film—not only the dryer display.
• Check different locations across the belt.
• Test the thickest ink deposit in the design.
• Verify performance after equipment or belt-speed changes.
• Perform stretch and wash testing as part of quality control.
• Document the successful belt speed and temperature settings.

Follow the cure instructions for the specific ink being printed. Do not assume every plastisol product uses the same temperature or dwell time.

Manual and Automatic Press Considerations

Manual Printing

Manual printers often benefit from ink that clears the screen with reasonable effort, maintains a workable open time and supports frequent job changes. Squeegee technique and screen tension have a major effect on the amount of force required.

Automatic Printing

Automatic shops may prioritize wet-on-wet performance, fast flashing, low buildup and repeatability across longer runs. Adjustable flood speed, print speed, squeegee angle, pressure and off-contact provide greater control, but they also make it important to establish documented settings.

The best production ink is the one that fits the press, garment, artwork and output requirements—not simply the most expensive or most opaque formula.

Store and Handle Plastisol Ink Properly

• Keep containers sealed when not in use.
• Prevent contamination between colors and ink systems.
• Use clean ink tools and mixing containers.
• Store ink away from excessive heat.
• Follow the manufacturer’s storage recommendations.
• Label custom mixes with the formula, date and job information.
• Return unused ink only to an appropriate, clearly identified container.

Plastisol Ink FAQ

What is plastisol ink used for?

Plastisol ink is commonly used to screen print T-shirts, hoodies, uniforms, team apparel, promotional garments and retail merchandise. Different formulas are available for cotton, blends, polyester and specialty applications.

Does plastisol ink dry in the screen?

Plastisol does not air-dry like water-based ink, so it generally remains workable in the screen during normal production. Excessive heat from a flash unit or hot pallets can begin gelling the ink and cause buildup or screen problems.

How do I know whether plastisol ink is fully cured?

The complete ink deposit must reach the cure conditions specified by the manufacturer. Measure the ink-film temperature and confirm the process with stretch and wash testing. Surface temperature or a dryer display alone does not prove complete cure.

Can plastisol ink be printed on polyester?

Yes, but polyester can present dye-migration and heat-sensitivity risks. Use an appropriate low-cure, low-bleed or polyester ink system and test the actual garment. Difficult sublimated fabrics may require a barrier-gray underbase.

What is the difference between high-opacity and low-bleed ink?

High-opacity ink is designed to cover the garment or underbase effectively. Low-bleed ink is formulated to resist dye migration from polyester. An ink can provide both characteristics, but opacity alone does not guarantee bleed resistance.

Can I mix different plastisol ink systems together?

Do not assume different ink systems are compatible. Use components from a documented mixing system or obtain confirmation from the manufacturer before combining products. Unapproved mixing may affect color, cure, bleed resistance and durability.

Should I add reducer when plastisol feels thick?

Not automatically. Mix the ink thoroughly and confirm the room and ink temperature first. If a reducer is needed, use a compatible product within the manufacturer’s recommended percentage. Too much reducer can weaken opacity and other performance characteristics.

Can Kolormatrix match a specific Pantone color?

Kolormatrix offers professional color-matching services for several ink systems. The final printed appearance can be affected by the garment, underbase, mesh and ink deposit, so provide complete production information when requesting a match.

Can plastisol be used for simulated-process printing?

Yes. Simulated-process plastisol ink systems are commonly used for detailed multicolor graphics on dark garments. Accurate separations, screens, registration, underbase control and press technique are essential.
