How to Create Spot Data in Photoshop

Introduction

This  section explains how to  prepare images that include spot data with  raster-based image
editing applications such  as  Adobe Photoshop®. In order to  print with  white ink or varnish, you
must have an ONYX profile (media  model)  properly  configured  for the  use of  spot data.

To  add spot color data to  your image in  PhotoShop, you  need to  create a  layer within the image
as a  new spot channel. It is  possible to  have more than one spot element in an  image, but each
element must be on the  same spot channel, and therefore have the same opacity level, or  else
ProductionHouse will  treat the saved document as a  separation file.  Since the Arizona printers
with white ink or varnish support  two spot channels, you can  create one spot channel for  Spot 1
data and another for  Spot 2 data. CMYK is  the   preferred image mode  as  the actions required for
spot data creation are simpler than  those  for  RGB.

NOTE

You can use raster-based image editing applications other than Photoshop as long as it has the
ability to create spot channels.

Purpose

When you have a  raster-based image and need to  have select areas of  that image show up  as
white when the media is  non-white or  clear or  translucent, you can prepare a  spot channel for  the
white data  in  Photoshop.

When to do

The first step in the  white ink or varnish workflow is to prepare your source image to  use a  spot
ink channel.  The  spot data must be  designed entirely on a separate channel (either as a  spot
channel layer or a custom spot color) to be recognized by  the  Onyx  RIP. The  name you  assign to
this  spot channel layer or  custom spot color must be  Spot 1 or  Spot 2 and is the  most important
part of  preparing the file.  This  named channel allows RIP-Queue to  determine that the data in  the
source image needs to be output to the  spot channel. In preparing your file,  only  you  can  define
what you want to  print with "white ink" or "varnish" as  part  of  your design and  assign the color as
described in this  document. Using your graphic application program, the spot data can  be  simple
or  complex and  can range from vector shapes  and text  to  halftone bitmap images.

New Spot Channel Layer

Use the following steps to create a new spot channel layer:

Procedure

Open the desired file in PhotoShop (if the file is in RGB mode, then convert it to CMYK mode).

Use the desired selection tool (e.g. the Magic Wand) to select the area of the image you wish to
print with white ink.

NOTE

The image file used in this example is for illustration purposes only. For best results when
working with text, we recommend that you use a vector-based program such as Adobe
Illustrator.

In PhotoShop, ensure that the Channels tab is visible (under the Window menu click Channels to
view the panel).

Click the arrow on the Channels tab to display the Channels menu.
