Inktek LB Base — Plastisol Mixing Base for PC Pigment Concentrate Color Mixing System

Open your Pantone® Solid Coated formula guide. Enter the target Pantone code in your formula software. The software returns exact gram weights of each PCPC concentrate per 1 lb of LB Base.

Tare your gram scale with a clean mixing container. Weigh out the specified LB Base amount. Add each pigment concentrate at the formula-specified grams directly on top. Mix with a drill mixer for 60-90 seconds until fully combined and uniform in color.

The mixed ink is ready to print immediately. Cure at 320F (160C) — verify with a donut probe. Log your formula, batch weight, LB Base lot, and production date so you can reproduce the same color exactly when the client reorders.

The primary use case. Use LB Base as the carrier for your PCPC pigment concentrate formulas. Open your Pantone Solid Coated guide, enter the PMS code, weigh the formula, mix — and you have a documented, repeatable color for every future reorder.

LB Base mixed inks maintain consistent viscosity across long press runs on automatic equipment. Wet-on-wet capability allows multi-color printing on high-speed automatics without excessive flashing.

Optimized for 100% cotton and cotton/poly blend garments. For 100% polyester or high-poly blends, print a low-bleed white underbase first to prevent dye migration into your mixed colors.

Excellent crock resistance and non-phthalate compliance make LB Base ideal for team and licensed apparel programs where color accuracy, wash performance, and compliance documentation are required.

Any shop building a Pantone color mixing capability from scratch should start with LB Base and the 15 PCPC pigment concentrates. The system produces hundreds of colors from a small, manageable inventory.

LB Base is equally suited for manual press operations. Consistent viscosity prints well through all standard mesh counts at manual press speeds without requiring additives or viscosity modification.

LB Base and all PCPC concentrates must be measured by grams on a calibrated gram scale. Visual estimation or volume measurement causes color drift between batches. A $40 gram scale pays for itself on the first reorder.

LB Base may thicken during storage, especially in cold environments. Before adding concentrates, use a spatula or low-speed mixer to modulate the base back to a smooth, creamy consistency. Adding concentrates to thick base produces uneven mixing.

Write down your Pantone target, gram weights of each concentrate, total batch weight, and production date for every color you mix. When the client reorders in 6 months, you reproduce the color in minutes — not by guessing from memory.

LB Base mixed inks cure at 320F (160C). Always verify with a donut probe on the ink surface — not just the dryer tunnel temperature. Run a wash test on every new garment or substrate before committing to production.

For dark or colored garments, print a bright white underbase first, flash to gel, then print your LB Base mixed colors on top. This dramatically improves color vibrancy and ensures your Pantone formulas reproduce accurately on dark fabric.

Store LB Base at 65-90F (18-32C). Never store on cold floors or in unheated spaces — temperatures below 32F can cause the plastisol to separate. Use within one year of manufacture for best results.
