As shown below, the Halftone Treatment can be used to create large-scale images in brand colors of high quality that are inspired by traditional printing techniques. The Halftone Treatment can change the limits of photo resolution into vector-like shapes that can work at any size.
Pretreated Images
A collection of pretreated images using the Halftone Treatment are available for download. These images may be used across print and web applications.
To Create This Effect in Photoshop
1 and 2) Open the image in Photoshop and go to Image > Mode > Grayscale to change the image to black and white.
3) Change the image again to Bitmap with Image > Mode > Bitmap... and then enter the resolution you want your image to be. (Ex. 300 Pixels/Inch) Under the Method: Use drop menu, select "Halftone Screen ..." then click Okay.
4) When the Halftone Screen menu pops up, enter the Frequency of Lines/Inch. (Ex. For a 300 ppi, use around 10 lpi.) The lower the number, the less dots will be used to make up your image. Experiment to make sure the image is still visibly distinguishable and clearly treated in halftone. (See "Incorrect Use" below.)
5 and 6) Once you have achieved the look you want, you may choose to cut out the image from its background.
You can also clean up the edges of your image by zooming in and removing stray dots.
7) Follow the instructions for the Gradient Map effect on your image. Always use Jefferson Blue as the darker color.
8) Once the image is flattened (Layer > Flatten Image), the image can be converted to CMYK for four-color printing or RGB for web. Your image is now ready for design and layout.
Incorrect Use: Halftone Lines Per Inch
Do not set the Halftone Screen at too small a number of Lines/Inch. The image still needs to be distinguishable. In this image, the lines per inch is much too small to tell it’s an image of the Homer statue.
Do not set the Halftone Screen at too large a number of Lines/Inch. The image still needs to have the appearance of a treated image, not just a black and white image. In this image, the lines per inch is much too large and the effect is wasted.
