Traditional analog printing must have five elements: manuscripts, plates, inks, substrates, and printing machinery to produce printed products.
First, the manuscript
The manuscript is the basis for plate making and printing, and the quality of the original manuscript directly affects the quality of the printed product. Therefore, it is necessary to select and design an original suitable for printing, and the original text should be maintained as much as possible during the entire copying process. The original has reflective originals, transmissive originals, and electronic originals. Each type of manuscript is photographed, drawn, lined, and continuously adjusted according to the production method and image characteristics. The definition and examples of each manuscript are as follows.
Table 2-1 Manuscripts and Features
Name Definition (or Description) Instance Reflection Original Document with an opaque material as the original document Reflection Lines Originals are made of opaque material and consist of black and white or color lines to compose images of originals, line drawings, and text originals. Photographic Line Originals Lined originals with opaque photosensitive material as their carrier. Photographs, Etc. Rendering Reflected Lines Originals are made of opaque paintable materials, and are hand-made or mechanically (printed) lines. Manuscripts, pattern drawings, drawings, prints, prints, etc. Reflective continuous originals are based on an opaque material and the tone value is a continuously-graded manuscript. Photos, drawings, etc. The photographic reflection continuously adjusts a manuscript into a continuous original with an opaque photosensitive material as a carrier. Photos and so on. Drawing Continuity Concluded originals are made of opaque paintable material and are made from continuous or manuscript-printed continuous originals. Drawings, prints, paintings, drafts, etc. In the real original copying technique, the physical person as the copying object is the total me. Drawings, fabrics, objects, etc. Original document with transparent material as graphic information carrier. Translucent line originals are made of transparent materials and are composed of black-and-white or color lines to compose the manuscripts. Photographic film and so on. Photographic transmission line negative originals are made of transparent photosensitive material as a carrier, and copy line artwork whose part is transparent or complemented. Black and white or color negative film, copy film and so on. Photographic transmission lines are originals with transparent photographic material as the carrier, non-graphically transparent line originals. Black and white or color reversal film, copy film and so on. Draw a transparent lined original with transparent material as the carrier, and hand or mechanically (printed) lined manuscripts. Film artwork, etc. Transparency continuous originals are made of transparent material as the carrier, and the tone value is a continuously-graded manuscript. Photographic film and so on. The photographic transmission continuous negative film manuscript is made of a transparent photosensitive material as a carrier, and a continuous tone original document that is partially transparent or complementary thereto is reproduced. Color, black and white photographic negatives and so on. The photographic transmission continuous adjustment film original is made of a transparent photosensitive material as a carrier, and a non-graphically transparent or continuous color-adjusted original is complemented. Color, black and white photographic reversal film and so on. Draw a continuous, continuous-tone original with transparent material as the carrier. Continually tune the original by hand or mechanically (printed). Film artwork, etc. Electronic manuscripts use electronic media as manuscripts for textual information carriers. CD library and so on.
