Manuscript Copy Printing Q&A II

10. What is a secondary manuscript?

A: The use of color photographic film, black and white photographic film (film), an imaging color photo paper, etc. as the image information carrier, the use of cameras and other cameras for the remake method, the Chinese painting, oil painting, watercolor painting, gouache, sketch, woodcut, sketch, color Photographs, black-and-white photos, drawings, patterns, lace, manuscripts, prints, etc., were converted into color reversal films, color pages, black-and-white pages, etc., and used for reproduction. These are called second manuscripts, or remakes. Originals.

11. What is a warm-colored manuscript?

A: In the spectrum, the colors are arranged in three bands: red, orange, yellow, green, cyan, blue, and violet. In the field of art, the colors of red, orange, and yellow long waves are called warm colors. Among the various types of manuscripts for copying, manuscripts whose main colors are red, orange, and yellow, and whose colors are truly and naturally presented on the screen are called warm-colored manuscripts.

12. What is the middle-tone original?

A: In the field of art, the green color between the warm and cold colors is called the middle tone. Among the various types of manuscripts that are copied, the originals that have green as the main tone and whose color tone is truly and naturally presented on the screen are called midtone originals.

13. What is cold tone manuscript?

A: In the field of art, the colors of blue, blue, and purple short-wave light are called cold colors. Among the various types of manuscripts for reproduction, manuscripts in which cyan, blue, and purple are the main colors, and whose colors are true and are naturally presented on the screen, are called cold-colored manuscripts.

14. What is an electronic manuscript?

A: Disc galleries, digital imaging, photocopies, and prints that use electronic media as an image information carrier are called electronic manuscripts.

15. What source of media manuscripts?

A: Media manuscripts come from CDs, magnetic media, music signals (MIDI), television signals (TV, VTR), camera signals, and CAPTAINS.

16. What source of software-originated manuscripts?

A: Software-based manuscripts can be either data or medical images obtained from measurements such as remote sensing, mapping, scientific measurements, etc., or they can be derived from computer workstations such as communication networks, CAD, CAM, design, transaction forms, animation, and Electronic typography and so on.

17. What are the characteristics of color photos that are not conducive to printing plates?

A: The color photo is amplified through a negative film. The tone curve has a shorter effective line, less tonal latitude, brighter tone, darker and easier convergence, coarser grain, and poorer resolution.

18. What are the disadvantages of printed manuscripts?

A: The disadvantages of printed manuscripts are as follows: 1 The image is textured and easily reproduced; 2 The particles are rough, and the ink, paper, and other particles and the printed marks and scratches are easily scanned out; Overprinting is inaccurate, edges are dewy, etc., making the image impractical.

19. What features of printed manuscripts are conducive to reproduction?

A: 1 The density of printed manuscript manuscripts is generally between 0.1 and 1.8, which is in accordance with the density range of the replica. Therefore, the scanning calibration can better reproduce the bright, medium and dark tone levels of the manuscript; 2 The brightness value of printed manuscripts and reprints can be the same, both of which can achieve a unified visual contrast; 3 Print manuscripts and reprints are made by overlapping dots, and their color saturation and ink thickness are basically the same. Easy to restore color.
