The procession of platemaking here is Computer to plate (CTP) ,CTP is an imaging technology used in modern printing processes. In this technology,one generation (transfer of film image to the printing plate) is removed from the printing process, increasing sharpness and detail.Plates are produced in less time, are more consistent. CTP can also improve registration and image-to-edge repeatability over traditional methods (wet proof).
CTP, the media is registered (held in precise position) in the platesetter during imaging, and does not rely on a separately-aligned pin grid, as is the case with film. Defects due to dust, scratches or other artifacts are minimized.
CTP increases dot gain slightly by eliminating the decrease in halftone dot size which can occur in the film-to-plate exposure process when positive film is used.
Therefore CTP systems is our vital key to improve print quality and productivity, We benefit it a lot. |
