Varnish Workflow OverviewIntroductionArizona printers with the Varnish Option can overprint varnish on top of a printed image inselected areas in a print job or as a flood coat. The printing of varnish applies only to flatbedprinting and is not available with the RMO.NOTEThe Varnish option is not available for print jobs that use the High Definition print mode. Varnishcan be used with all other print modes.Printing varnish creates a high value-added special effect. However, since this is an additionalprocess after printing image data, it also decreases productivity. Due to the low productivity ofprinting large areas of varnish, it is best to concentrate the use of this feature on spot decoration.Fortunately, the Arizona printer "blank space" skipping feature skips over areas in the print that donot contain varnish, and greatly improves the net productivity of spot applications.Varnish is printed as a second process after the CMYK(W) image is printed. Immediately afterprinting a CMYK(W) image. The gantry moves to the start of image position and prints a varnishspot or printer generated flood data using three additional passes.NOTEVarnish is actually "clear ink" and is for decorative purposes only. It does not provide additionalprotection to the printed image.Spot Versus Printer Flood FillVarnish data can be applied to a print job in two ways: Printer Flood Fill or Spot Data.• A Printer Flood Fill is like an auto-fill that is done by the printer, where varnish data fills theentire bounding box (the rectangular area that defines the total perimeter) of the image.• Varnish Spot data can be defined in image editing applications such as Adobe Illustrator® orwith the Spot Layer tool in the ONYX workflow.The Spot Data can be defined as either Spot 1 or Spot 2. The same spot data can be used to printeither varnish or white ink, or both.Varnish Workflow Data PreparationVarnish print job output can be accomplished in a variety of ways depending on the desiredresults and preferred working process. There are three primary methods. The workflow optionsare:• Printer flood fill configuration,• ONYX software Spot Layer Tool, and• Varnish spot data image preparation.Printer Flood Fill Configuration in the ONYX workflow does not require any pre-rip filepreparation and is the easiest method of achieving varnish output. All that is required is toconfigure ONYX to use a Varnish Flood. The printer flood encompasses the bounding box (theouter border of the image) of the file being processed.ONYX Software Spot Layer Tool offers many options to process an image, and thus allowsvarious possible configuration choices. You can save these configurations as Filters and placethem in a Quick Set and this makes it possible to re-create with minimal effort settings that areoften used. All work with the Spot Layer tool requires an ONYX media profile with at least onespot colour.Varnish Workflow Overview130 Chapter 9 - Manage a White Ink Workflow
