1. the first printing press produced work by
-relief printing
-recycling old paper
-scanning text into a machine
-using colored ink and screens
The correct answer is relief printing. To arrive at this answer, you can eliminate the other options by understanding the history and mechanics of the first printing press.
1. Recycling old paper: While paper recycling is an important practice, it does not pertain directly to the first printing press. In fact, the first printing press did not focus on the recycling of old paper. This option can be eliminated.
2. Scanning text into a machine: Scanning technology did not exist during the time of the first printing press. The first printing press was invented by Johannes Gutenberg in the 15th century, well before the advent of modern scanning equipment. This option can also be eliminated.
3. Using colored ink and screens: The first printing press did not incorporate the use of colored ink and screens. Initially, the printing press used oil-based ink, which was mainly black. The technology for colored ink and screens came much later. This option can also be eliminated.
4. Relief printing: Relief printing is the correct answer. Johannes Gutenberg's printing press used relief printing, which involved setting movable type in a frame, inking it, and pressing it against paper to leave an impression. This process allowed for the efficient production of printed materials.
By eliminating the other options based on historical knowledge and understanding of the printing press's mechanics, we can determine that the first printing press produced work through relief printing.
