Inktek Solar White Plastisol Ink — Low Cure, Soft Hand, High Opacity Screen Printing Ink for Cotton & Poly Blends (3-Gallon Pail)

The 3-gallon format is 60% of the weight of a 5-gallon pail — easier to lift off a shelf, carry across the shop, and tip without spillage. It also ships at a lower freight cost per reorder than a 5-gallon, which adds up on a high-use production white. If you’re going through gallons regularly, the 3-gallon pail keeps costs tighter without requiring a full 5-gallon commitment.

Solar White delivers a clean, vivid white that pops on both light and dark garments. The high-opacity formula covers the substrate fully in a single pass on most fabrics, with consistent brightness from the first shirt to the last in a production run — no color shift, no thinning out mid-job.

The most commonly printed substrate in the market is a cotton/poly blend — and it’s also the most likely to show dye bleed under a standard white. Solar White’s low-bleed formulation is specifically validated for 50/50 blends and tricky blend fabrics, holding clean at the 280°F cure temp without the bleed risk that standard whites carry on those substrates.

The smooth laydown and excellent fiber matte-down produce a clean, retail-quality print surface — no raised edges, no texture variation, no fuzzy fiber ends standing through the ink film. The soft hand feel stays soft through washing, making it suitable for fashion and retail apparel jobs where the feel of the print is part of the product.

Solar White works well across mesh counts and squeegee types without needing adjustment. Run it at 86–110 for heavy underbase deposit, 160–230 for tighter graphic detail, or up to 305 for fine halftone and simulated process work. The consistent press-ready viscosity means no thinning in most cases — open and print.

First-down on dark cotton and cotton/poly blend shirts. Gel at 155–165°F flash temp to dry-to-touch, then print top colors wet-on-flash. High opacity blocks the substrate for accurate, vibrant color results on top.

Last-down highlight white in simulated process and multi-color prints. The bright, high-opacity formula adds clean white accents that pop against any background color without a second pass.

Solo spot white on any garment. Consistent opacity, reliable bleed resistance, and a clean finish make Solar White a dependable single-color option across the full substrate range.

Solar White holds well on 50/50 blends and many poly-blend fabrics, but dye chemistry varies by garment manufacturer and colorway. Highly reactive polyester dyes — especially in dark reds, royal blues, and bright athletic fabrics — may bleed at any temperature. Always pre-test the specific garment and colorway before committing to a production run. If you’re seeing bleed on test prints, switch to a dedicated dye blocker underbase.

155–165°F is the flash gel point — when the ink is solid enough for the next screen to print on top. Full cure requires 280°F through the entire ink film for at least 90 seconds. A print that passes a quick touch test after the flash unit has not been fully cured. Always verify full cure with a donut probe and wash test before shipping.
