Like four-color process separations, simulated-process color separations are done in Photoshop. They tend to be more vivid than four-color process prints and can be printed on darker materials, unlike four-color process separations. The difference is that simulated process color separations utilize a range of ink colors. Like traditional four-color process separations, simulated-process color separations make use of halftone dots to create highly detailed or photorealistic images. These types of separations are usually done in Photoshop, and creating a process color separation and printing four-color process correctly can be tricky.
The four-color process uses halftone dots of CMYK - cyan, magenta, yellow and black - to create detailed, photorealistic images. Spot color separations are usually created in CorelDRAW or Illustrator. While they are typically solid, spot color separations can include some halftone dots to create a shading effect. Spot color separations are done for vector images. The most common type of color separations used in screen printing is spot color separation. Common screen printing color separations include:
Understanding the different types of separations, and the challenges they present, can help you execute successful separations on a routine basis. There are a handful of separation processes that screen printers use. Color separations are vital to the screen printing process, but they can be tricky! Here are the basics to get you started.
