If you have set a media colour, you have three options for how you would like the media colourto be handled. The term “Knockout” means to remove from the selection. If you’ve set a mediacolour, chances are you want some portion of the design to be removed to use the media colour.These are the option you have to choose from:• No Knockout - If you’ve set a media colour to help you visualize your output, choose thisoption. This will print the image and spot data with no knockout.• Spot Knockout - If you choose this option, RIP-Queue removes the spot data anywhere theimage data matches the media colour that you set. Use this option when you want to knockoutthe spot data but still print the image data that matches the media colour.• Full Knockout - If you choose this option, RIP-Queue removes the spot data and the image dataanywhere the image data matches the media colour that you set. Use this option when youwant to knockout the spot data and the image data, allowing the media to fully show through.Spot ChannelThe Arizona 1360 and 1380 printers have two spot channels available. The names that appearshere should be the ones you used to create the media in Media Manager. The recommended spotchannel names are: "Spot 1" and "Spot 2".NOTEONYX software treats Spot 1 and Spot1 as equivalent. The space between "t" and "1" is notimportant but the case is, so the "S" must always be capitalized.Flood FillThis option generates a flood fill for the entire image by combining the underlay and mask fillstogether. When you check this option, the underlay and mask fill sliders lock together and are setat 100%. You can change the opacity for the flood fill by moving either of the sliders.Underlay Fill OpacityThis option generates a fill in the selected spot channel where image data exists. The fill will begenerated anywhere image data does not match the mask.Mask Fill OpacityThis option generates a fill in the selected spot channel where mask data exists. The fill will begenerated anywhere the image data matches the mask colour.Choke and SpreadChoke reduces the outer edge of the underlay. Use choke when you want to eliminate white frompeeking out of the edge of your image. Spread increases the outer edge of the underlay fill. Usespread when you want a deliberate halo around the edge of your image. Choke and Spread workin tandem. Each mark on the slider represents 1 pixel width of choke or spread up to 10 pixels(+-) .The actual preview in Preflight is exaggerated from what is printed. This exaggerated displaymakes it easier for you to see the results from moving the slider. When you use the Spot LayerTool for masks, we recommend a choke value of 3 ticks.Diffuse EdgeUse this option when you want a gradual transition from the underlay to the mask to create a softedge for the fill. We do not recommend use of this option.FilterOnce you’ve defined your settings, save them by exporting a Filter to use on similar jobs. Filtersare a global colour correction that can be applied to Quick Sets to automate the printing processfor multiple jobs that use the same settings.Create Spot Data with the Spot Layer Tool138 Chapter 9 - Manage a White Ink Workflow
