What does proofreader mean

Question 1: What is a proofreader? According to the drawings, data and models to make the actual thing, do this work is the proofing staff p>

Question 2: proofing staff do what the main proofing is based on customer requirements, make a product out for customer review, if there is no problem, the customer confirms that OK, you can do the samples, generally in large quantities before the production, will want to confirm that OK samples, p do not know how to answer this can let you quickly! Understand?

1. Why sample?

The made plate, mounted on the proofing machine for test printing work, called proofing. Proofing to correctly reproduce the original tone levels and colors. Proofing is an important process.

The role of proofing is: ① check the quality of each process of plate making. The use of proofing to test the effect of color separation, etc., feedback to the previous process, in order to change. ② To provide customers with the basis for proofreading. Proof sheets can be printed after the customer's signature. ③ for the official printing ink color, specifications and other basis and reference data.

2. What are the types of proofs?

① Mechanical proofing (analog proofing):

Mechanical proofing is the use of proofing machines, and printing conditions are basically the same conditions, the printing plate on the graphic ink transfer to the substrate, printing a small batch of samples of the method. This proofing method completely simulates the printing method, is the principle of pressure to achieve the transfer of graphic ink, can more accurately reflect the performance characteristics of the printing plate and printing process, sample and print more consistent.

② photochemical proofing: photochemical proofing is a kind of plate, in the plate before the sun through the soft plate, the use of the exposure imaging principle of the system sample method. This proofing method is the use of certain light-sensitive materials in the light conditions, adhesion or solubility changes, leaving the corresponding dichroic color on the base of the dot image. Photochemical proofing currently have diazo sheet proofing method, color powder proofing method.

Diazo sheet proofing method is a use of diazo photographic material and the original plate superimposed exposure, by the development of other processing to produce a sample of the method. Diazo film exposure imaging principle and color principle is: light-sensitive layer of diazonium salt decomposition reaction occurs, the diazo base disappears, the color fades; not see the light of the diazonium salt in the alkaline conditions, and coupling agent coupling reaction occurs, the formation of azo image. Different coupling agents get different color images.

Chromalin proofing method, also known as Cromalin (Chromalin) proofing method, the photographic film by the base, photographic layer and protective film, etc., the photographic layer is a photopolymerization type, the use of its photoconductive viscous changes in the selective adsorption of chromogenic color powder, the formation of proofing images. The photographic layer also has the property of being softened by heat, using this feature in the proofing of peeling and bonding.

③ soft proofing (screen proofing)

Soft proofing samples, is to show the effect of the image on the display to predict the printing, the color and content of the image. Display screen display color gamut and printing process is very different, so this form of proofing is an imprecise color communication tool. One of the main reasons is that the computer display screen using RGB color light phase mixing to show the effect of the image, in line with the color light plus color theory; and printing samples using yellow, magenta, cyan ink on paper for overprinting, in line with the theory of color material minus color.

④ Position proofing

Position proofing samples, which are obtained from the color separation softcopy or digital files, are basically used to detect the group of live pieces of the plate. These samples are used to test the content, registration, color mutation and spot color position. Position samples include continuous tone samples for photographic effects, blue samples, and color register samples. Digital proofing systems that are used only to display color and do not have to have the ability to accurately predict press results can also be used for positional proofing. These systems generally offer speed and cost advantages.

⑤ Digital proofing

Digital contract proofing is by electronic files, through the output of the digital printer output sample, does not produce any soft film. The quality of digital proofing equipment has been improved to the extent that many kinds of equipment can be used to produce the same sheet. When the printing industry is increasingly close to the workflow of the support of Yimer, some manufacturers are producing digital proofing equipment, these proofing equipment can match the analog system, fully simulate the effect of halftone dots. Digital systems have a number of known benefits, including savings in time, materials, and effort, and the use of equally accurate digital information in the design, proofing, and platemaking steps of the process.

Question 3: Proofing What does it mean Proofing [dǎ yàng]

1. To draw a design before building a house or manufacturing machinery or apparatus.

2. After typesetting a book or newspaper, etc., a proof is first printed for proofreading.

Question 4: What is the meaning of proofing in printing Proofing

The purpose of proofing is to produce samples to meet the quality requirements for the school reviewers and plate making, printing process to provide the basis and standards. Sample is a printed ink color rules sample, with a visual reflection of the image reproduction reproduction characteristics and predict the function of testing the quality of printing, is used to test the quality of pre-press and sign the sample of the basic elements and the basis for the pre-press company and the customer, pre-press and printing process to exchange views between the confirmation of the quality standards of the media and the basis. As a sample must meet the two basic requirements: one is high quality; the second is to use the existing printing conditions can be produced out of the enterprise.

Proofing is to test the quality of pre-press production, pre-press process to provide characteristics of the parameters. Through proofing, the sample to check the graphics version of the enamel specifications, graphic content, positioning overprints, etc. is correct, test layout color, level, gray balance, uniformity to meet the quality requirements; at the same time for the pre-press production process to provide the color value, gray balance value, dot expansion value and other characteristics of the parameter.

Proofing is to simulate printing and provide proofs for customers and editors. Customers and editors proofreaders through the sample to review and predict the quality of the print effect, to confirm the quality standards of the official printing, and acceptance and sign the sample to print.

Proofing is a trial production, the printing process to provide standard samples. Printing process based on the sample material and machine adjustment. To sample as a standard for printing production and inspection of print quality.

Question 5: What is the meaning of the gift company said proofing? Proofing is in accordance with your requirements first to do a physical out to you to confirm!

Question six: electronic factory inside a term called ---- proofing, this proofing means what? Yes, electronic factories are doing electronic products or circuit boards, anyway, proofing means that the new product or have changed the old product before the production of the first batch of trial production, it is just that the amount is not much, the purpose is just to try to be feasible;

Question 7: proofing what it means to "proofing", the Northeast dialect.

It is the first to do a look, others act accordingly.

For example, if a few friends are drinking, and one of them says, "I'm going to make a sample," and dries it up, then the others will have to finish their glasses with the others.

Question 8: What does PCB proofing mean? The drawings will be sent to the circuit board factory processing into a prototype, and verify the function is called PCB proofing. I have done in Guangzhou Penghao Electronics Co., Ltd. batch, I heard that they have a department that specializes in sampling, 3, 4 sampling small single will also receive.

Question 9: Seek! Wuxi people say "proofing" what is the meaning of the same Shanghai dialect, is ready to buy a thing first casually look, probably an impression, do not consume.

Question nine: What do they mean by "playing the sample"?
