Ulano Screen Making Products

Indirect Stencil Film

Indirect films offer superior fine detail reproduction; sharp printing edges; uniform stencil thickness; predictable standardized exposures; close control of stencil thickness, hence ink deposit; fast and simple stencil production; and easy stencil removal for efficient mesh recovery. All Ulano gelatin-based Indirect Films are totally solvent resistant. The topcoat on Ulano Indirect Films prevents tackiness underconditions of heat and high humidity.

Ulano Gelatin Indirect System Photographic Films provide the ultimate in stencil resolution and definition. The film is exposed, developed in A + B solution to harden the exposed aread, (except Ulanolux UP3 and Pulsar), washed out and adhered to the mesh of a screen. After drying and blocking out, the transparent backing is removed.

All Indirect System Photographic Films consist of a light-sensitive emulsion coated on a transparent base or backing sheet, with special adhesives.

Indirect Films, (sometimes referred to as transfer films), are ideal for applications involving shorter (2,000 - 4,000 impressions) printing runs, fine details, and excellent definition; and for easy, reproducible, clean stencil production.

EXPOSURE TIPS
Underexposed: Stencil will be thin (and look thin) resulting in poor press endurance. Underexposing for resolution much finer than the job you will print sacrifices durability.

Overexposed: Stencil will be thick (and look thick) resulting in poor adhesion due to overhardening.

    Benefits
  • Press-ready stencils in as little as 30 minutes
  • Stencil thickness, hence ink deposit, can be adjusted by exposure
  • Superior solvent resistance
  • Dimensional stability of backing material promotes excellent registration
  • Humidity-protective topcoat layer guards against tackiness under humid conditions
  • Completely phthalate free
  • Simple handling requirements
  • No messy chemicals, no liquid emulsions
  • No darkroom or soft-blanket vacuum frame required
  • Presensitized
  • Stencil can be examined before transfer to screen
  • Excellent storage properties
  • Fast, easy stencil removal
  • Optical flatness of support layer promotes excellent definition for line and halftone work.

Synthetic Polymer-based Photographic Films

Pulsar -develops with tap water

Product Fact Sheet Technical Data Sheet MSDS More Pulsar Info

Pulsar on GlassAn innovative stencil system offering the industry’s most rapid method of making photographic stencils. Pulsar features exceptional imaging fidelity, control of EOM (emulsion over mesh thickness), and wide processing latitude. It has excellent solvent resistance and develops with tap water.

Non-gelatin diazo-sensitized coating on a 3-mil (75µ) optically clear polyester backing that develops with tap water.

  • Can be exposed, washed out (in room temperature or cooler water)
  • Fast exposing
  • Excellent adhesion to polyester and all other mesh
  • Wide exposure latitude
  • Not recommended for use with aggressive solvent inks
  • Non-gelatin film so only use conventional stencil remover like Ulano No. 4 Stencil Remover Liquid or Ulano No. 5 Stencil Remover Paste to reclaim the stencil

Hi-Fi Green® Ideal for general printing applications on a vinyl backing

A thick, green gelatin coating on 5-mil matte vinyl backing. The vinyl backing helps hide dust, tape marks and positive edges very well, reducing the need for touchups. There is a slightly textured surface to the stencil bottom, allowing easy lift off when printing on smooth surfaces under humid conditions. The thick backing facilitates the handling of large format stencils and coarse mesh and is excellent for heavier ink deposits
Resolution: 125 - 150 microns (5 - 6 mils).
