All Indirect System Photographic Films consist of a light-sensitive emulsion affixed to a transparent base or backing sheet, with special adhesives. Indirect Films are exposed, developed (except synthetic polymer films), washed out and then adhered to a screen.

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. The topcoat on Ulano Indirect Films prevents tackiness underconditions of heat and high humidity.

Pulsar - Control your EOM with exposure and no chemical development

Product Fact Sheet Technical Data Sheet MSDS

Pulsar is an innovative stencil system offering the industry's easiest, fastest method of making photographic stencils for solvent inks and mesh counts above 230/inch (90/cm.).

Reclaims easily with modern stencil removers like Ulano No. 4 Stencil Remover Liquid or Ulano No. 5 Stencil Remover Paste.

• Resolution: 80 -100 microns (3 -4 mils) - Exceptional imaging fidelity
• Control of emulsion over mesh thickness (EOM), with exposure
• Wide processing latitude
• Excellent solvent resistance
• Completely processed with un-heated tap water

Fewest processing steps
• User friendly - No A+B chemical development step after exposure
• No image distortion from swelling
• No temperature-controlled washout require
• No developer required - Wash out with tap water
• No mesh influence during exposure - Less costly white mesh can be used
• Easy to reclaim
• Can be used with a wide variety of mesh counts 156 and finer
• Precise, reproducible control of EOM (emulsion over mesh) thickness with exposure - Control of ink deposit and ink costs
• Indirect stencils can be inspected off-mesh - Eliminates time-consuming makeovers
• Fastest press-ready system -Less labor and production time -High volume stencil throughput
• No emulsion haze or pigment stains to post-treat
• Special layering system allowing for wide exposure gradient

Pulsar (Synthetic) Indirect Film Processing Instructions

ADHERE PULSAR TO THE MESH
Place the washed out stencil, emulsion side up, on a hard, raised, flat surface.


Lower the screen, wet from the preparation rinse, onto the Pulsar.


Place a sheet of newsprint (unprinted newspaper stock) on the squeegee side of the screen and, with a roller, apply very firm pressure to blot the film into the mesh.


Remove the sheet of wet newsprint, replace it with a dry sheet, and blot again.


Repeat this several times, or until the newsprint begins to stick to the stencil. Firm blotting assures good adhesion. (For those accustomed to gelatin-based indirect films, note that Pulsar is blotted with a single sheet of newsprint rather than a pad; blotting should be done with firm, not gentle, pressure.)
