•
Allow for bleeds if you're sending an image for professional printing: If
any color runs to the edge of the image, extend the canvas by 1/4 inch on
all sides to ensure that the color is properly printed even if the trim line is
not exact. Your service provider can help you determine whether you have
bleeds and how to prepare your file to ensure it prints correctly.
•
Unless you're printing to an inkjet printer, convert the file to CMYK.
Note: Some high-quality printers are inkjets; ask your service provider
what color space your image should be saved in.
•
Flatten the file to reduce its size for faster transfer and printing speeds.
Make sure you keep an unflattened copy of the original so you can make
changes or reuse the content later, if necessary. Photoshop prompts you to
merge layers when you convert to CMYK.
•
Soft-proof the image to ensure the colors will print as you expect them to.
Getting started
You'll prepare an 11''x17'' travel poster for professional printing. The Photoshop
file is quite large, because it contains several layers and has a resolution of 300
dpi, which is necessary for quality printing.
First, start Photoshop and restore its default preferences.
1.
Start Photoshop, and then immediately hold down Ctrl+Alt+Shift (Win-
dows) or Command+Option+Shift (Mac OS) to restore the default prefer-
ences. (See “
Restoring default preferences
” on page

.
)
2.
When prompted, click Yes to delete the Adobe Photoshop Settings file.
3.
Choose File > Open, navigate to the Lesson14 folder, and double-click the
14Start.psd file. Because the file is large, it may open slowly, depending
on your system.
4.
Choose File > Save As, navigate to the Lesson14 folder, and save the file
as
14Working.psd
.
