If you need to make a personalized poster, Photoshop is the most versatile choice there is. This tutorial will show you how to create a simple poster in Photoshop, from setting up the document to combining graphics and text.
I will be using a red curtain texture and a silhouette of a dancing couple to create a simple event or business poster
Launch Photoshop and start a new document (File>New). Some of the
standard poster sizes are 8.5” x 11," 11” x 17," 18” x 24," 24” x 36,”
and 27” x 40." For this tutorial, I will pick the small 8.5” x 11."
Before confirming, set the color mode to CMYK with a 300 pixels/inch
resolution.
Enable Photoshop’s rulers (View>Rulers). Right click on the rulers
and set the unit to inches. I will create a margin of 0.125” for each
border to ensure nothing will be cut off after printing.
Click on the vertical ruler and drag to set the first guide to 0.125”
and the second to 8.375." Repeat for the horizontal ruler, setting a
guide to 0.125” and the other to 10.875." No element of your design
should extend over these margins.
Open the background image — in this case, the curtain texture. Right
click on the background’s layer and choose Duplicate. From the menu,
select the poster’s document as a destination. Use the transform tool
(Edit>Transform) to adjust the background’s size to the poster’s area
and confirm when you are done.
