How Metal Lunchboxes Were Manufactured
- Factories took large, flat rolls of steel and cut them down to the appropriate size.
- The sheets were then run under print rollers in a process known as lithography using CMYK
(Cyan, Magenta, Yellow, and Black) which is the standard four-color printing process that is used
today. In the 60s a process called embossing was applied to some of the boxes to give them
a three-dimensional look.
- Once the inks dried, the steel sheets were then formed or stamped into the lid and box shape thus
beginning to take shape as the lunchboxes The type of box would determine how the sheets were bent. ex. Regular flat rectangle, dome, or carry-all.
- The final process was to add the remaining parts such as: hinges, clasps, and handles.
