Plate burner
Encyclopedia
A plate burner is part of the CTF
print workflow. In a CTF workflow, a sheet of light sensitive film is imaged directly from a RIP
. The film must then be developed immediately after wards. This film is then placed onto a printing plate, on the plate burner. Registration of the plate and film is controlled by a pin grid. After securing the plate and film to the grid, a glass cover is lowered upon the plate and film. The film and plate are placed into a vacuum on the plate burner to remove any pockets of air and ensure the film is in close contact with the surface of the printing plate. Once the vacuum is established, a high power (5 kW) UV lamp (also associated with the burner) is turned on, which "burns" an image through the film and onto the plate. The plate is then processed, and put onto the offset printing
press.
Computer to film
Computer to Film is a print workflow involving the printing from a computer, straight to film. This film is then burned onto a lithographic plate, using a plate burner. The plate is then put on an offset printing press to make a product...

Raster image processor
A raster image processor is a component used in a printing system which produces a raster image also known as a bitmap. The bitmap is then sent to a printing device for output. The input may be a page description in a high-level page description language such as PostScript, Portable Document...
