27. The absolute chroma color conversion method will cause the color to have a greater loss in lightness and saturation.
28. Using the relative chroma color conversion method may cause the two different colors on the original image to obtain the same color after conversion, thereby causing the colors to lose their original contrast relationship.
29. Metamerism can only be established for specific standard observers and specific illuminants.
30. The photosensitive CTP plate refers to the plate with a photosensitive coating, which is exposed with high-power ultraviolet light or visible laser. The photosensitive layer on the plate surface absorbs light quanta to produce a photosensitive image.
31. The CTP plate-making machine applying violet laser technology uses a laser with a wavelength of 400 nm as the exposure light source.
32. The thermal type plate is imaged using the absolute thermal energy of infrared laser. In the thermal technology, the critical value is the key to forming an image: below the critical temperature, the printing plate will not generate an image; the critical temperature or above the critical temperature, Lucky Second Glue, the printing plate generates an image, the size and shape of the generated dot Not affected by temperature.
33. CTcP direct plate-making machine uses laser as the exposure light source.
34. One of the cores of color management is the color conversion module (CMM). CMM is used to create device signature files.
35. Acrobat is a software platform based on PDF format, it can convert other format software into PDF format file input, and can convert PDF format into PS language output.
36. The purpose of the CIP3 alliance is to develop and advance the vertical integration of pre-press, printing and post-press processing.
37. The "Printing Industry Management Regulations" are promulgated by the Press and Publication Administration. It is applicable to the printing business activities of publications, packaging and decoration printed materials and other printed materials.
38. "Printing Industry Management Regulations" stipulates: printing business license shall not be sold, rented, lent or transferred in other forms.
39. Production and management personnel, production technology and equipment, and operation management are the three major elements of an enterprise, of which "operation management" is the first element.
40. To keep the scanning quality stable, the scanner should be warmed up for at least 30 minutes.
41. Color correction should be performed on the basis of ensuring gray balance.
42. PDF / X-1 is mainly used in commercial and packaging and printing industries.
43. The same RGB value displayed on different devices will produce the same color effect.
44. When the aperture of a digital camera is fixed, the amount of light acting on the imaging plane depends on the shutter speed and lens diameter.
45. No quotation marks, brackets, or titles are allowed at the end of the line.
46. ​​Thread binding is a binding style in which the middle seam is folded in half and several papers and face and back covers are superimposed on the drupa, and the thread is threaded at an appropriate width on the left side.

51. Use WORD to automatically convert DOC files into book sample files.
52. Using book version software can automatically convert DOC files into book version sample files, and support the conversion of mathematical formulas.
53. When printing blood charts with variable data printing, you should know the finished size of the book, generally it is better to exceed the incision 13mm.
54. The basic functions of proofreading are twofold: similarities and differences, proofreading. Correction of similarities and differences refers to comparing proofs with the manuscript word by word, and finding and correcting errors in recording and arranging by finding the similarities and differences between the two.
55. The basic functions of proofreading are twofold: similarities and differences, proofreading. Proofreading refers to finding and correcting possible errors and omissions in the original by judging the inherent contradictions of the original.

61. UCR process can reduce the ink overprint rate of the image part.
62. Both digital cameras and scanners use RGB three-color filters for color decomposition.
63. The maximum scanning resolution of the scanner represents the physical optical resolution of the scanner.
When purchasing floor mats, we should first make clear our own needs. Generally speaking, for indoor floor mats, the main material can be acrylic, cotton and microfiber. If you choose a floor mat for the bathroom, the main reason is that it absorbs water. Therefore, cotton or microfiber floor mats should be selected, especially microfiber materials. People step on it directly after taking a bath, which not only absorbs water quickly, but also feels very comfortable.
Our floor mat product back adhesive selection of natural latex coating, non-toxic, odorless, no deformation, no sticky, no mildew.
