What type of paper can diazo printers NOT copy drawings on?

Diazo printers, which are commonly used for producing blueprints and similar documents, operate by utilizing a chemical process that is sensitive to the type of paper used. These printers typically require paper that has specific absorption characteristics to effectively capture the diazo compounds involved in the printing process.

Bond paper, specifically designed for various types of printing and drawing, possesses properties that allow it to absorb the diazo chemicals effectively. In contrast, glossy paper is coated and treated to have a shiny, smooth surface that resists ink absorption. This surface prevents the diazo chemicals from adequately transferring to the glossy paper, resulting in poor quality prints or no print at all. Therefore, glossy paper is the type that diazo printers cannot effectively copy drawings on.

Understanding the materials and their properties is crucial for ensuring compatible printing results, especially in specialized printing applications like those involving diazo technology.
