KIMOLEC PF-90S   It is a specially coated, polyester film with excellent thermal stability for use in laser printers. The direct imaging of this film does not require a darkroom. The quality of the text and image reproduction is determined by the laser printer in use. Therefore, the laser printer should have a resolution of 600 dpi or higher.   Features : Direct imaging by laser printers Daylight processing High density Direct copy on to the printing plate Time and cost savings Chemical free Optional density increase through the use of KIMODENS spray   Kimodens spray The optical density of KIMOLEC PF-90S laser film depends on the laser printer's toner technology. If a higher density is required, the simplest and cheapest method for occasional after treatment is Kimoto's KIMODENS PF-DENS SPRAY. It contains a special agent that refines and homogenises the grain size of the toner. This increases the density value up to 3.5. Spray evenly on the exposed side of the Kimolec PF-90S film from a distance of 30-40cm.   The film is ready to be exposed after few minutes drying time.
