CT/LW filter

The CT/LW filter converts multiple CT, LW, and header files (LH, PG, or ASSG) into a single combined PostScript or PDF file.

CT/LW files contain information about photographic imagery, line art images, or text and lines from drawings. Together, CT (Continuous Tone) and LW (Vector Line Work) determine the appearance of the final output.

The CT/LW filter is a feature of Fiery Graphic Arts Package, Premium Edition, and Fiery Productivity Package. To apply this filter, the Fiery Server must have one of these enabled.

The CT/LW filter accepts multiple CT and LW files and, when present, a header file. The filter determines the dimensions of the combined file based on the FP, LW, and CT files, in that order. Spot colors are converted to process CMYK using conversion values specified in the CT/LW files. The combined file is a single RLE compressed CMYK image, and you can specify the resolution.

When you drag and drop your CT, LW, or FP files, your output is a single PostScript file.

You can drop or download page folders containing the CT, LW, and header files one page at a time, which is the recommended way to submit CT/LW files to a Hot Folder (because it ensures that hidden files are also transmitted to the Fiery Server).

Note: Some CT/LW files may include a "." (period) at the beginning of the file name, which indicates that the files are hidden. When processing CT/LW files, you can turn on Show Hidden Files in your folder settings to show invisible files. To copy all files, including hidden files, drop the entire CT/LW page folder that contains all the necessary files onto the Hot Folder.
