PDF Render
 |
PDF Render accepts only PDF data and allows you to perform color management before outputting the re-screened raster data to an imagesetter, platesetter or proofer.
PDF Render performs trapping, separation, rendering and screening of the data. Each of these processes have their individual settings. You can view these settings either when creating Parameter Sets, or from the Settings pane in the Plan tab of the Job Manager and the Ticket Editor.
•In the Trapping process, overlaps between adjacent colors are created to account for press misregistration, paper stretch or other variables.
•In the Separation process, a composite job is separated into different colors. On a press, each separated color has its own printing plate, each one printed in a different angle, producing the final printed color image. In traditional prepress, color images are separated into four layers corresponding to the four process colors (CMYK) used in process printing: cyan, magenta, yellow and black. For more information on these settings, see “PDF Render - Separation Settings”.
•In the Rendering process, you can specify your settings for Color Management and Overprint.
•In the Screening process, continuous tone files are converted into halftone dots. This means that the image is converted into a number of dots in the predefined separation colors. You can enhance the quality of the image by adjusting the dpi (dots per inch) and the lpi (lines per inch), also called ‘line frequency’. Every line consists of a number of dots. For more information on these settings, see “PDF Render - Screen Settings”.
