Printing Processes

Identifying the printing method for deltiology is important for collectors of postcards.

Chromolithography

Chromolithography was a process that involved printing images using multiple layers of color to achieve a high level of detail and vibrancy. This method was particularly popular in Germany at the time and was known for its ability to produce colorful and intricate images.
The process was quite labor-intensive and required skilled lithographers and pressmen, as it involved numerous color runs and a longer production time. Despite the complexity, this method allowed for the creation of high-quality, artistic postcards that were sought after by collectors and the general public alike.

Heliocolor

It was the name of an 'Autochrome' printing process introduced by Emil Pinkau & Co, Leipzig, c. early 1901. 'Heliocolor' process printed cards from the early years are usually of high quality. Later cards are of standard quality

Letterpress

This process involved printing from a raised surface, and it was commonly used for monochrome or two-color printing, which fits the description of a black and cream postcard1. The letterpress technique was known for its ability to produce crisp, clean lines and was widely used for various types of printed materials, including postcards
