The drawing would then be outlined in Indian ink on tracing paper or tracing cloth. Then, coated paper and tracing will be laden into the frame that was then brought out to sunlight. It will then be exposed to sunlight with varied time from less than a minute to about an hour under a cloudy sky. The operator will see the blue image appear through the tracing. The frame will be brought indoors when ready. The material will then be washed in running water to remove the unexposed coating, and then it will be dried. A clearly legible copy of the drawing will emerge with a white line and dark blue background. This copy possessed unrestricted resistance to light and to water that is as good as the substrate.

Today, conventional blueprints have been replaced by more contemporary, cheaper printing methods and computerized products. These days, designs are created using Computer aided design techniques that may be transferred as a digital file directly to a computer printer; in some applications paper is shun altogether and work and analysis is done directly from digital displays.
