Hot (Foil) Stamping

What is it?

Fast and economical, “hot” or “foil” stamping is a dry process whereby a roll of pigment or metallic foil is transferred to a surface using heat, pressure, and a die.  It can be a cost-effective method to decorate parts.  The process works well for Polypropylene, Polyethylene, Delrin (non-medical), and other hard to print plastic materials.


Liberty Clark will hot stamp most surfaces.  Medical Grade film images or text information can be applied on a special order basis.

Screen Printing

Flat Screen Printers – Cylindrical Screen Printing – High Volume Screen Printing.  When an “image” to decorate a part is too large for one of the pad printers, Liberty Clark has the option of using a screen printer. We have screen printers capable of printing both flat and round articles.  Silk screening is another method used to add graphically detailed images to your finished parts. Using artwork provided by your art department, or developed by our staff, we can apply multiple colors to your product.  Automated and hand screening methods are available based on the volume requirements of your project, and are applied by highly experienced operators.  In general, silk screening is used on larger printable surfaces that are flat, although some minor part curvature can be accommodated.  To print parts such as signs, displays, mail totes, books, or 3-ring binders, we would use our flat screen printers.  Screen art or screen images should not have type below 12pt. (san serif) or 16pt. (serif). All rule lines should be one point or greater.  LARGE REVERSE images should be avoided regardless of the products.  Heavy ink consistency processes offer high-opacity and brilliant color possibilities.

The process is ideal for Acrylic glass ice scrapers, banners, posters and most any other surface you can think of.  Enamel, epoxy, and baked acrylic inks offer durable, solvent resistant decoration to your housings, enclosures, and device front panels.  A proven technology, silk-screening enables us to reproduce your logo in great detail on flat surfaces.  If desired, multiple colors can be printed from your E-mail sent artwork.  Information traditionally affixed to your enclosure by the label can often be economically silk-screened for a much more professional look.  We also do silk-screening and pad printing in high volumes using vinyl, acrylic, and epoxy inks on plastic enclosures and thermoformed parts – call or send a drawing for a free estimate.

Cylindrical Screen Printing

Our “cylinder” screen printers may be adjusted to screen print parts with slight tapers.  With these machines, we have successfully screen printed syringes, small plastic tubing, and many consumer products.

Heat Transfer

Heat transfer may be suitable and economical for multi-color decorating needs. The process involves graphic images transferred to a surface material using heat and pressure. 


Images are created to “chemically” bond to the target surface.  Our heat transfer images have been successfully applied to the following substrates:

  • ABS
  • Acrylic (cast and molded)
  • Polyphenylene (PPO)
  • Cellulose Butyrate (CAB)
  • Polyphenylene Sulfide
  • Polypropylene
  • Polyethylene
  • HDPE
  • LDPE
  • PVC
  • Leather
  • Wood
  • Polysulfone
  • SAN
  • Styrene (GP & high impact)
  • Polyamides (nylon)
  • Textiles
  • Polycarbonate
