Conclusion

After 1950, many of the processes, styles, and/or techniques discussed in this exhibit declined in popularity, especially with the continued evolution of printing technology and color theory. The rise of the Photochrome postcard in the 1940s and 1950s negated much of the need for linen postcards and white borders, both of which also declined in economical necessity with the end of the Great Depression and World War II. The CMYK process and hafltone principles continue to be used to this day in printing, including with the production of Photochrome postcards, capturing a broader and more accurate range of colors. However, these methods and principles are applied with technologies and techniques that are much improved from almost 100 years ago.
