Glow-in-the-Dark Powder when mixed into Excalibur clear bases produces a dramatic special effect where the print made with this ink will glow yellow-green in darkness or low-light situations. Light will penetrate through the clear base activating the pigment creating a bright, and long lasting glow effects when the printed garment is worn in a dark environment. Simply add 10-23% by weight and stir thoroughly. Also if mixed ink has been stored always stir ink prior to printing as pigment can settle to bottom of container. While this effect can be created in any Excalibur base, it produces the best results when using larger amounts of powder combined with a clear base and coarse meshes.


  • Can be mixed with any Excalibur mixing base to produce a variety of effects on many substrates.
  • When mixed with Excalibur clear bases light easily penetrates to activate pigment and  produce a bright and long-lasting glow effect.
  • Completely phthalate-free and lead-free formulation complies with all standards of Consumer Product Safety Improvement Act (CPSIA) banning phthalates and heavy metals in textile-printing inks.


Mixing Ratio: Add 10-25% by weight and stir thoroughly.  If mixed ink is stored pigment may settle and should be thoroughly stirred prior to printing.

Gel Temperature: Ink will gel on surface at 240° F (116° C).

Curing: Prints will fully cure when the entire ink film reaches 320°F (160°C) for at least 15 seconds.

Substrate: For best results the Glow-in-the-Dark ink should be printed directly upon a white 100% cotton t-shirt or on top of a white underbase.

Mesh: Mesh counts between 110–160/inch (43T-64Tcm) may be used and choice of mesh will be dependent upon detail in design and opacity level required.. Coarser meshes will reduce detail in design but will produce a brighter and longer-lasting glow effect.

Stencil: Any emulsion compatible with plastisol inks.

Modification: Not recommended if mixed with any Excalibur clear base.  If absolutely necessary and only after ink has been thoroughly stirred in the container  Excalibur 501PF may be utilized in small amounts (5-10% by weight)  to reduce viscosity.

Squeegee: 70 durometer or 90/70/90 triple durometer blades are recommended.

Clean-up: Use Enviro Series 2000 Green or Enviro Series TR Blend.


For best results mix Glow-in-the-Dark Powders into the following clear bases where light can easily penetrate through the print thus quickly charging the pigment and creating a long-lasting glow effect.  Clear bases available are: 554PF, 700PF, 701PF, 833PF, 838PF, 900PF, 905OF, 908PF, JP2000PF.


Glow-in-the-Dark Powders can be mixed into the following standard Excalibur mixing bases.  Please note that the glow effect will not be as dramatic because these bases contain components that enhance opacity.  The bases available are: 400PF, 504PF, 550PF, 551PF, 750PF, 820PF, 825PF,835PF, 837PF, 904PF,914PF, 950PF, 951PF,960PF, 961PF,1504PF,1550PF, 1551PF,3504PF, 3550PF, 3551PF.


Always test finished prints for curing, adhesion, bleed-resistance, ink film thickness and desired look prior to beginning full production runs. Lancer Group International cannot guarantee the results or back claims that standard colours or mixed inks will test phthalate-free if any additive other than an additive manufactured by Lancer Group International is used to modify this ink. Test results by a third-party laboratory verifying all components used to produce this ink are phthalate-free and lead-free are available upon request.
