Simulated Process Separation
routine will separate an Image that
can be printed onto any color of shirt.
To do this the background of the image (i.e. the areas that will be the shirt color) must be transparent. This is important to remember when creating your designs.
If your design is only being printed onto black or white shirts you can simply use those individual separation routines that just require a black or white background.
After separation, this design will be ready to print on to any colored shirt, black, white, green, yellow, whatever you like.
If you want to separate an image that has a black background and it is going onto a black shirt you can just use the "Separate for Black shirts" routine which does not require you to remove the background.
In Photoshop® navigate your way to the Tutorials folder on the EasyArt® CD and double
click the image file "Classic Car.psd" to open it.
to the layers list (Window > Show Layers) you can see this image
has been created on four different layers. The background layer, car layer,
logo layer and the 21st Century type layer.
Before separating this image you must first delete the blue background layer. ( if not deleted this will also separate as part of the image).
To do this select the blue background layer and drag it down to the bin icon at the bottom of the layers list.
EasyArt® can only
separate one layer so the remaining three layers must be merged into
Save this image to your hard drive as a Photoshop
file (.psd) to preserve the transparency, give it the name "classic car flat".
The image is now ready for some adjustment, to improve the overall color and sharpness, to produce the best possible separations.
Step 1 Preparation
Go to the Actions list (Window > Show Actions) and scroll down
and click on the yellow EasyArt® button "Improve
Image RGB". This will automatically intensify and sharpen the image.
Step 2 Separation
To separate scroll down to the blue EasyArt®
button "Separate for
colored shirts" and click.
|The speed of
the routine will depend on the speed of your computer, a message "Routine
Complete" will appear when it has finished. Click continue.
With the separation routine complete the separated image appears on a gray background, this is the default shirt color for this routine.
Before inspecting the separations, change the default shirt color back to the blue the original image was on, so it will give a better visual representation.
To do this, scroll down
to the blue EasyArt® action button "Change shirt color" and click.
To inspect the
separations go to the channels list, you can see EasyArt® has created 11 spot color
channels including a white base and a highlight white.
Step 3 Adjustment
To produce this image as an 8 color print, go to the channels list and turn off the Magenta, Green, and Grey channels this will leave us with the 8 channels we need.
To produce this design as a 6 color print go back to the Actions list and click the
green button "combine brown channel" this will automatically create a simulated brown using the
Red, Yellow and Light blue channels.
Go back to the channels list and turn off the Magenta, Green, Dark Brown, Grey and highlight white channels, leaving you with a 6 color print.
What you are trying to do is eliminate having to print the brown channel, but instead of just leaving it out (then gaps may appear) you are making a simulated version of the brown, so that you get the same or similar effect without having to print a dedicated color.
Printing out separations
Printing instructions only apply to those printers that are able to print out Halftone dots
Before printing out the separations turn off the top 5 channels in the channels list, RGB,
Red, Green, Blue and shirt color. (you don't need to print these) The printer will only print
out channels that are turned on. (the eye showing).
In the Half tone screens window that appears click the "Load" button,
Double click the file "halftone-screens" to load.
Back in the "Print” window click the "Registration Marks" Box and the "Labels" box. Orientation should be Portrait for this design. Press “Print”.
This will print out all of the channels that you have turned on.
