Well it's pretty easy, just follow these steps to make a poster in the style of a Soviet Propaganda Lithograph.
First maybe you should look at some real examples: Soviet Propaganda Research
Step 1: Create a New Document
Open Photoshop and create a new document with the settings 8x10 inches @ 72dpi.
Step 2: Wrinkled Paper
I changed the color and brightness of this image a couple of times over the following steps until I got something which went with my color scheme; I added a 'color mask' with which I set to Multiply at 55% transparency and I adjusted the images hue and saturation a bit.
Step 3: Imagery
Step 4: Desaturate
If you want to keep some of the original colors go to Image > Adjustments > Hue/Saturation and reduce the saturation to a desired level.
Step 5: A Poster Aesthetic...
I used Poster Edges for my first image.
Step 6: The Time Is Now
Double click on the layers for your image and wrinkled paper and do the following steps:
select color overlay - choose the color you wish
change the Blend Mode to Multiply
then change the Opacity to about between 50 and 75%.
Step 7: For Text.
Step 8: Color Dodge
Now with your text there are a few things you can play with:
I used the Rectangle Tool behind some of my text and put a Drop Shadow on the boxes
You can also add a Stroke around your text if you need some contrast between it and the background by double clicking on your text layer and selecting Stroke and changing the color and size of your stroke. If you wanted some depth you could repeat this last option but instead of selecting Stroke you could choose Drop Shadow.
Step 10: More Imagery (optional)
- Get an image from your computer or off the internet
- Remove the background
- Desaturate it!
Step 11: Step '5'...I Mean '11'
Use one of the following filters: Poster Edges, Cutout, or Sumi-e
