Printing Terminology

- Apr 09, 2019-

1. Bleeding:

Any image that exceeds the cut line or enters the book slot. Bleeding must indeed exceed the pre-high line so that a small amount of misalignment is allowed during trimming or stapling.

2. Total bleeding:

(full bleed) The portion of the printed image that is beyond the four sides of the paper. Since almost no press can print on the edge of the paper, all four sides must be cut.

3. CIElab:

A device-independent color space, usually described in three variables (L, A, B).


Cyan, magenta, yellow, black - four printing colors. YMCK and KCMY are synonymous with CMYK. YMCK may be a spelling method formed by people's habits, and KCMY may be a radio station of Nebrasks. In printing, the order of the letters may also imply the printing sequence of the four-color printing. Therefore, KCMY often indicates that the ink is printed in black, cyan, magenta, and yellow.

5. Client/Server: (client/server)

A central control computer called a "server" is a computing mode associated with a decentralized computer called a "client." Clients can take advantage of the software on the server to do a specific job.

6. Color gamut: (color gamut)

All colors that can be processed by a color printer.

7. Color separation: (color separation)

A method of converting an original into a structural form compatible with the color printing process.

8. Color space: (color space)

A three-dimensional or four-dimensional positioning coordinate system, each representing a color defined by three (RGB) or four (CMYK) variables.

9. Cutting line: (crop marks)

A line printed on the periphery of the paper to indicate the cut.

10. Density: (density)

Reflectance density refers to the ability of a surface to block light; transmission density refers to the ability of a filter to block light.

11. Direct plate-making: (direct-to-plate)

The typed digital page file is directly output from the host computer to the laser platesetter, eliminating the need for negative film production, also known as CTP (computer-to-plate).

12. Download: (download)

Transfer data from one computer to another or to a device such as a printer.

13. Phototypesetting machine: (filmsetter)

Another name for laser imagesetters is mainly used to make image color separations.

14. Four-color printing: (four-color printing)

Use the subtractive color three primary colors (yellow, magenta, cyan) and black for printing. If the effect of orange and maroon is printed in brownish yellow ink, it should not be called "four-color printing" but should be called "special color printing". "Or "color printing."

15. Gray balance: (gray balance)

An important feature of the color reproduction process. Blending of cyan, magenta, yellow inks or color formers can produce achromatic neutral ash in the color space.

16. Printing printing:

A process technique that uses a plate or other means to transfer graphic information on an original to a substrate.

17. lithographic planographic printing:

A printing method that uses a lithographic print.

18. Offset ink offset lithography:

The graphic on the printing plate is printed on the intermediate carrier (rubber cylinder) and then transferred to the substrate.

19. Offset printing press:

According to the principle of indirect printing, a printing plate is printed by a blanket transfer roller to transfer a graphic onto a substrate for printing.

20. Printing process printing technology:

Implement various specifications, procedures, and methods of operation for printing

21.DTP (Desktop Publishing System)

Color desktop publishing system: input images and texts into a computer, use computer to process and process images, draw graphics, and then combine graphics, images and text into a whole page layout, and use laser imagesetter to make this electronic The layout output becomes the original version of the printing plate.

22.CTP (Computer To Plate) computer direct plate making:

The further development of printing technology can not only directly make a manuscript, but also realize the direct interface between the computer publishing system and the printing machine, from the original to the printing.

23. Indirect printing:

The ink on the graphic part of the printing plate is transferred to the surface of the substrate by the transfer of the intermediate carrier.

24. Original original

The graphic information on the physical object or carrier on which the plate making is based.

- Plate printing plate:

A printed graphic carrier for transferring ink to a substrate. Usually divided into four types of relief, gravure, lithography and stencil.

- Printing board printing stock:

A variety of substances that can accept ink or adsorb color and present graphics.

- Plate making:

The process of copying into a plate according to the original.

- Image plate making image reproduction:

Copy the general name of the image manuscript by hand, lighting, electronic, etc.

- Nettone, halftone, screen tone:

The tone of the picture represented by the dot size.

- Positive image:

In black and white and color reproduction, the hue and gray tone are the same as the image being copied.

- negative image negative image:

In black and white and color reproduction, the hue and gray tone are the opposite of the object being copied.

- color separation color separation:

The process of decomposing a color original into individual monochrome versions.

- Computer phototypesetting system computerized phototypesetting system:

A set of typesetting equipment consisting of a character and typesetting instruction input device, a calibration device, a proof output device, a control device, and a photo-distribution host.

- Text layout text composition:

A process in which a text original is formed into a prescribed layout according to design requirements.

- Imposition make-up:

Put text, graphics, etc. into a version according to design requirements.

- Printing plate printing down:

The process of transferring the information of a negative or positive film to a printing plate or other photosensitive material by contact exposure.

- proofing proofing:

Copy the proof from the graphic information of the puzzle.

- Pre-coated lithographic plate presensitized plate:

A lithographic plate that can be applied at any time by applying a photosensitive layer in advance, referred to as the "PS" version.

- Post-press finishing:

A manufacturing process that produces a desired shape and performance of the print, such as binding.

- Double-sided printing

With two different plates, both front and back printing are done simultaneously on the same substrate.

- Original version of the block copy:

Graphic film for printing.
