PREPRESS Vanish that varnish
The situation: a job calls for varnish at final output, but the customer doesn’t want the varnish to be visible in the proof. The output workflow management features of Prinect Printready System offer several solutions:
• Set the varnish to “ignore” in the properties of the signature when making a proof, and reset it to “output” for final output.
• Change the CMYK equivalents of the color “varnish” in the job settings to CMYK 0%, “type,” “opaque and ignore” and “overprint.” In “prepare,” enable “output all colors.” When the PDF is proofed, the varnish won’t be seen as it has 0% CMYK representation. However, it will be output as a solid tint on the plate as indicated in the output preview feature of separation control in Adobe Acrobat.
With Prinect Printready System, it’s possible to work with user-defined color tables if every varnish is named “varnish.” Create a new color table in Administration/Resources/color table and put it on top of the list. (The tables are checked from top to bottom.) Create a new color named “varnish” with the settings 0/0/0/0, “opaque and ignore,” and “overprint.” In job settings, enable “take color definitions for new colors from color tables.” In “prepare,” select “output all spots” at spot color treatment. Remember not to convert the varnish into process color as this will result in overprinting 0% CMYK.
