Table 2.

The plate-making process of the three major plate-making methods.

Category		Plate-making process
Manual imaging plate making	Hand-painted legal version	In the clean screen, the use of Arabic gum is directly painted, dry after the full plate coated with shellac, and then the printing plate immersed in the temperature of 50-60°C in water, after the Arabic gum melted, the graphic part is exposed, blank part of the mesh is shellac-blocked
	Plate making by cutting	On the paper or transparent plastic evenly coated shellac thickness in 3-5 mm, dry in the film to depict the manuscript, and then through overheating, transfer the manuscript to the net cloth
	Sealing method version	Draw the drawing ray wants to print on the stretched mesh, andthen use the pen to fill in the blanks
Photosensitive imaging plate making	Engraving film and plate making	A hollow-out mold is carved on the film, and then the mold is pasted on the screen to form a printing plate
	Direct plate-making method	In the stretched net cloth coated with photographic glue, and then paste on the film, exposure, development, drying, and other processes, the final formation of a printing plate
	Indirect plate making method	Using positive negative for exposure and development, and then transferred to the mesh, plug hole, sheet base stripping, and forming of a printing plate
Digital imaging plate making	Straight plate making	In the dry mesh on the photosensitive film, and then coated with photosensitive adhesive, film base stripping, combined with positive negative exposure and image production plate
