ouve made a great design for a client and now they need it printed on T-shirtsand they

have asked you for separations. Although talking to a T-shirt screen-printing company for

advice is always a good idea, here are the basics of making spot-color separations.

1 THE BASICS OF SEPARATIONS

Before we go into a detailed description of creating separations in hotoshop, heres a!uick primer. A two-color logo, in this e"ample green and gold, re!uires two separations#

one for each color. $hen you look at the separated artwork, whatever is being printed at%&&' appears black while anything using less ink (to create a lighter color) appears in

shades of gray. *otice that some of the design is missing on the gold color artwork where

the green te"t will print.

2 WORKING WITH EXISITING ARTWORK

$hen youre working with e"isting artwork in hotoshop and you dont have layers, you

have to manually create the separations by selecting each main color and creating spotcolor channels. +our ob will be easier if you either have an image with a limited number

of colors, or you alter some colors to limit the total number of colors. To get started, open

hotoshop and go to $indowApplication rame to set up your canvas (youll need this

for the ne"t step). Then, go to ile/pen to open your e"isting artwork.

3 CREATE A SECOND DOCUMENT

/ne of the simplest ways to create a spot color version of a document is to create a

second document the same si0e as the first. To do this, go to ile*ew and in the *ewdialog, click the reset drop-down menu and choose your e"isting artwork document.1lick /2. This will create a new document the same si0e as your original. To make

things easier, go to $indowArrangeTile to create a split screen of your two

documents.

4 SELECT THE FIRST COLOR

3n your original document, choose 4elect1olor 5ange to select your first color. (1hoosea main color at %&&' opacity, not a color thats at a reduced opacity.) 6ake sure the

3mage radio button is active, and use the 7yedropper tool in the dialog to select an area of

your first color (we chose the dark red color) in the dialogs preview section. After

youve made your selection, activate the 4election radio button to see your selection as amask, with the white areas representing your selection and the black areas indicating

what isnt selected. 8sing this option will help make your selection precise.

5 FUZZINESS AND PREVIEW OPTIONS

9ery often youll need to move the u00iness slider to include all the selected areas, butif you do, be careful not to go too far, or similar colors will be selected. /ne way to help

with this is to change the 4election review from *one to $hite 6atte. This will show a

preview on your document with your selection in color and everything else in white. 3nour e"ample, the selection we made showed that some of the lighter red color was being

selected, so we pulled back the u00iness slider slightly (well add the lighter colors

later).

6 ADD A SPOT CHANNEL

1lick /2 to accept the color range settings and press the 6 key to select the 5ectangle

6ar!uee tool (or any mar!uee tool, it doesnt matter which one). lace your cursor on aportion of your selection and your mouse will turn into a white arrow with a small

selection bo" underneath. $hen this happens, click-and-drag your selection into the

second document, and then hold down the 4hift key to center it on the document. Then,in the 1hannels panel ($indow1hannels), click the flyout menu and choose *ew 4pot

1hannel.

7 CHOOSE THE SPOT COLOR AND FILL

3n the *ew 4pot 1hannel dialog, name the channel and make sure that the color swatch

holds the color you want to use. 1lick /2. :epending on the advice you get from thescreen printing company, you can either choose a antone color or ;any< color that yourscreen printer will replace with the actual colorthe important thing here is separating

the colors. 4ince you have a selection, the spot channel will automatically appear in color

in your document, and black on white in the 1hannels panel.

! SELECT THE LIGHTER VERSION

*ow go back to the main document and select the lighter, reduced opacity version of the

first color (in this e"ample, the lighter red color). Again, use any mar!uee tool to drag-

and-drop the selection into the second document, and press-and-hold the 4hift key to

place the selection in the center of the document.

1" FILL THE FIRST SPOT CHANNEL

6ake sure the appropriate spot channel (for our e"ample, the red spot channel) is activein the 1hannels panel, and then go to 7ditill. Because we want this to print as a lighter

version of our color, select @&' ray from the 8se drop-down menu and click /2. /n

the document image, youll now see some lighter red areas while on the spot channel inthe 1hannels panel youll see %&&' black and @&' black.

11 FILL#DELETE OTHER SPOT CHANNELS

5epeat this operation for each of the lighter colors, clicking the appropriate spot channel

before filling. /nce youre done filling the spot channels, you can delete the other default

channels (5B, 5ed, reen, and Blue) by selecting them in the 1hannels panel andclicking on the :elete 1urrent 1hannel icon (trash can) at the bottom of the panel

leaving you with ust the spot channels that you created.


11/14

12 VIEW EACH SPOT CHANNEL

ust to make sure that everything worked the way you intended, take a look at each spot

channel, remembering that %&&' black represents %&&' of your color and the gray areasshow where the color will print lighter. To do this, click the 7ye icons on and off before

each spot channel in the 1hannels panel. To view your first spot channel, turn off theother channels 7ye icons, leaving the first channels icon on. 5epeat for each channel.

13 DO A TEST PRINT

+ou can also do a test print to make sure that each color prints as a separation the way

that you e"pect. 1hoose ilerint and in the rint dialog, make sure 1olor 6anagement

is selected at the top right. 4et 1olor Candling to 4eparations. 3n our e"ample, we chose

Dandscape for orientation and enabled the 4cale to it 6edia checkbo". $e also wentback up to the 1olor 6anagement menu and selected /utput. 3n the rinting 6arks

section, we enabled the 1alibration Bars and 5egistration 6arks checkbo"es. *ow whenyou print, you should get a separate piece of paper for each of your spot channels.

re!uire# they may be happy to get your hotoshop document saved as a standard 4:, or
