How to Create White Spot Data in Photoshop
• If you intend to use this file in a vector-based program such as Illustrator, save it as a
.PSD file in order for all channel information to be carried over. The white spot color
is printed in the order it appears in the Channels palette, with the spot channel
printing underneath CMYK data. However, when exported as a .PSD to Illustrator,
this data will appear above the image data. This is the correct format protocol for Il-
lustrator.
• Save as TIFF and ensure that the spot colors option is enabled if you plan to bring
this image directly into ProductionHouse.
• It is also possible and sometimes preferable to print directly from PhotoShop to Rip-
Queue. For instructions on how to do this, see document provided on the Onyx web
site "Printing From a Mac", which also contains information on printing from Win-
dows-based systems.
