New Excalibur® Solution from Lancer Enables Foiling Effects with Plastisol Printing Print E-mail
801 Foil Proof from LancerLancer Group International has launched 801 Foil Proof : a clear coat plastisol that repels foil.  Previously, foiling effects were only possible in designs printed with water-based, not plastisol inks.  Lancer now has the solution: simply screen-print Foil Proof over top of the plastisol where foil is not required to stick.  When you heat seal the foil onto the image, the foil will only stick to the parts of the design that are not clear coated. 
Lancer recommend the following materials and technique:

Recommended Mesh:
80-110 t/in. (32t to 43t/cm) for image areas requiring foil.
160-200 t/in. (48t to 80t/cm), on image areas that don’t require foil.

Adhesive systems:
Use 845 Printable Adhesive for areas to be foiled or tint 845 PA with ink colour similar to foil.

801 Foil Proof Enables Foil Effects within Plastisol Printed DesignsPrinting Procedure and Tips:
• For best results use 80-110 t/in. (32t to 43t/cm) mesh counts with a print/flash/print routine to “build up” the areas to be foiled.
• On non-foil areas, use a finer mesh. The goal is to achieve a thinner ink film than the area(s) to be foiled. A print/flash/print routine with 801 Foil Proof is also suggested for maximum foil resistance.
• The addition of 820 Puff Base to 845 Printable Adhesive creates a low loft, which results in a higher surface area for the foil to adhere to. As a starting point, we recommend adding 25% of 820 Puff base, by weight, to the 845 adhesive.
• Adding small amounts (3% by weight or less), of 801 Foil Proof to the ink will also aid in resisting foil. Be aware that adding more than 3% will affect viscosity and opacity.
• Gelling, instead of fully curing the print initially, will result in a much better foil transfer. Heat pressing the foil at 375° (191°C) will contribute to proper cure. You may also consider putting the foiled garment through the dryer again at normal curing temperatures.

Foil Application:
Set heat press to 375°F (191°C) - apply with very light pressure for 4-6 seconds. Peel foil slowly while still warm.

As always, testing is strongly recommended prior to any production.

In wide-format digital print, innovation means everything to me in my work as a consultant where I deal with manufacturers, suppliers and end users. These are the people who will shape the future of our industry but end customers need to be made more aware of the potential which is available to them and their applications.
