How design ideas are better realized by printing
Prepress work refers to the preliminary work of the printing process, including typesetting, color separation and scanning. Its work mainly lies in the proficiency in the software used by the computer in the prepress operation, the basic workflow of the printing process, and the good graphics and image processing capabilities. When we get prints, we are often disappointed, because we often find that our own design concepts are not well reflected, or some colors are not printed properly, which leads to some deviations in our design. How to make our design ideas better realized by printing? This is the issue to be discussed below. I think that for printing to be a design service, the following points must be fulfilled: first, designers should have certain prepress knowledge; second, prepress preparation; and third, close cooperation and communication. Only in this way can the design go wild, and the development of computer technology also supports the realization on the computer screen. However, due to certain limitations in equipment, process technology, communication and understanding, and the lack of printing knowledge by designers, design and printing do not match well, resulting in unsatisfactory printed works. When the work is finally released, the design company will be required to provide corresponding cooperation. The designer's understanding of printing knowledge can ensure that the design idea is unimpeded and better realized. 1. Prepress knowledge that designers should have ①If the designer's printed product adopts a cross-page design, it means that the text or image on one page will span to the next signature. At this time, it is best to make sure that the paper guide and the gripper are printed on you. The location in the factory, and then place the material as close as possible to that area; in addition, try not to split a text on two signatures to print, so it is easy to make mistakes. ②Always guarantee your bleeding position (generally 3mm, but with the development of technology, some printing plants have been <3mm, so in order to save money, the designer and the printing plant need to communicate closely). Any image that exceeds the cutting line must leave a certain margin outside the cutting line, so that people are not allowed to correct the small amount of registration when trimming and cutting. This margin is called bleeding. Therefore, when cutting a stack of pages, appropriately increasing the amount of bleeding can improve the cutting quality of the entire job. ③For the printed documents sent to be die-cut, the die-cut line should be stored in a separate layer or contacted by phone for instructions to ensure that the printed part is separated from the die-cut line. ④The choice of paper. There are various types and specifications of paper, which must be selected to suit the work. For example: some papers may be too thick to be folded multiple times; some papers may not be suitable for UV coating, and some papers may take many days to dry completely , And some papers can only be coated with water, otherwise they will be damaged by the binding equipment. Designers should consider these factors. ⑤When you are still in the idea stage, you should get in touch with the binding factory to let them know what you are thinking. Not only can they help you achieve your goals, but they can also provide you with many cost-saving suggestions. [next] ⑥ When the file is determined as the final draft, the unnecessary paths created in Photoshop must be deleted. RIP is very troublesome because it keeps some unnecessary paths in the image. ⑦The designer occasionally uses Macromedia Fontographer software to modify the font. Although they sent new and modified fonts, ATM often could not recognize it as a valid font file. At this time, font replacement is required, and sometimes it can only be replaced with another font. For designers, most of the modified fonts are title words, so to set the title words in the illustration software, it is best to convert the font to a path after finalizing the design, and then put the words into the spring and autumn typesetting software. The font becomes a vector file, the font file is no longer needed, and errors are reduced. ⑧ After finalizing the design, the designer should pay attention to whether to include pictures in the file. The designer placed the linked picture in the typesetting software, but when sending it to the output center, he forgot to send the picture placed in the file to the output center, so when outputting, either the picture is wrong, or a low resolution is obtained Rate pictures. Or the designer did not link the pictures at all, such as the files produced by the financial company. The pictures in these files are often copied and cut into the file from Microsoft PowerPoint or Excel. At this time, the typesetting file contains only a WMF file. When the picture is being processed, either the line width is wrong or the color is cast. Therefore, re-create the illustration in Adobe Illustrator or some other suitable illustration software. Do not insert it into Illustrator by grabbing or cutting. The best way is to first trim the border, and then output it as an EPS file. Into Illustrator. ⑨The effect of the designer's resolution in Photoshop on the image. Small resolution will inevitably affect the quality of printing. Too large a resolution will affect the operating speed of the computer operation. The image resolution should be twice the number of printing screen lines, lower than 2 times can not meet the print quality requirements, higher than 2 times is a waste. For example, if the printed product uses 175 lines, the image resolution should be 175 × 2 = 350dpi. The image zoom ratio should not exceed 20%. If there is spot color printing, we should establish a spot color channel, and pay close attention to the overprinting method. Just use the appropriate resolution and use the smallest memory to ensure the best print quality. Why not do it! ⑩RGB images must be converted to CMYK to avoid inaccurate colors or even multi-color to gray. RGB is generally used in design or color inkjet, and CMYK is used in printed products. So you should also pay attention to the process of making printed products, because the color will become darker during the conversion process from RGB to CMYK. Pay attention to the Mac (MAC) archiving process, and note that the PC and Mac (MAC) compatible formats. The designer should also make corresponding cooperation for the post-printing. When the designer understands the basic printing knowledge, if he understands some printing processes: such as UV, hot stamping, hot silver, laser and other effects, that will be for your work It's the finishing touch! [next] 2. Preparation before printing ①The density of all films should be above 3.8, the bleeding position ≥ 3mm, the finished size is correct; and the film must not have scratches, creases, and keep clean; all hot stamping content such as pressed on the base map or background color, the corresponding content cannot Make the highlighting on the base map or background color to avoid inaccurate set; there should be a clear color code on the film to avoid misspelling; the film surface of the film is correct to avoid the serious loss of the printing dots; if it is cross-image, glue Book cover 2 and the first page of the text connected to it, cover 3 and the text of the last page connected to each have 3mm overlapping connection positions, and other texts have 0.5-1mm overlapping connection positions to avoid cross-picture connection ; The text at the binding place must be more than 8mm away from the spine of the front and back 8P and back 8P of the bound book cover, to avoid being unclear after spreading the book; the text of the saddle stitched book should have a certain distance from the incision, in general Next, the distance between the first post's text and the incision is preferably ≥ 3mm, and then each post is added by 1mm, that is, the distance between each post's text and the incision is preferably ≥ 4mm, and so on. The color draft provided should be the final proof. If the text has been revised and the film has been reproduced but not re-proofed, it must be clearly marked in the corresponding position of the proof to avoid misunderstanding. If the color is changed, you must reprint the paper to avoid printing and color problems. ②If it is from an electronic file, please pay attention to the design software used by the printing house. The software is preferably: PDF, Acrobat Professional. QXD, Quark Xpreess. AI, Illustrator. INDD, InDesign. PM, PageMaker. FH, Freehand. And clearly tell the software type and version number used, such as Chinese version InDesign CS2, etc., file format, the file format is preferably: PDF: Fonts and high-resolution images must be embedded. PS: Including fonts and high-precision pictures. ③Paper pattern: Provide the final pattern of the electronic document. If the paper pattern is different from the electronic file, it must be clearly marked on the paper pattern and the file format should be explained. ④Size: The finished size of the document must be informed, and any scaling and adjustment must be clearly marked. The composition of the file should be divided into three folders, such as fonts, images, and typesetting, and be stored in a standardized manner. [next] 3. Close cooperation and communication ①Communication in the design process: In order to ensure that the design ideas can be better realized by printing, if there are special designs or designs involving new processes, it is best to determine whether the design ideas can be finally realized before determining the design plan. It is better to realize and whether there are other better design methods and other (aspect) issues. Consult the printing company. It is better to allow the printing company to participate in the process design plan to avoid subsequent problems. In addition to providing sufficient professional technical support, the printing company should also actively share with customers the successful experience of other product process design cases. ②Communication in the pre-press production process: Although the development of computer technology allows computer makers to independently create fairyland scenes, it is impossible to make their works perfectly displayed in the world because of the certain process limitations in the subsequent printing and binding process. Therefore, communication is more important in the pre-press production process. The printing company should provide sufficient professional technical support to the designer, and the designer must produce and process electronic documents according to the printing company's actual tooling and process level according to the printing company's requirements. ③ For communication during the entire printing process, the two parties should maintain close contact and promptly discover and quickly deal with various problems that may be found in the entire printing process and that may not meet the design requirements. When a printing company finds a problem, if equipment, process and technical problems should be solved by itself first, if it still cannot be solved, it must be promptly submitted to the customer, and if necessary, it should provide sufficient professional advice for the customer to make reference when making a decision. Customers should also promptly and promptly resolve relevant issues after learning about the relevant issues, to avoid greater losses and delays. If it can be handled on site, it is the best way to communicate and resolve. ④Communication after delivery, after the product is delivered, if both parties can maintain corresponding communication, sum up experience, master the customer's demand orientation, which is conducive to long-term friendly cooperation. Especially for the printing of magazines, the relevant staff of both parties can make summaries and communicate together, which can help shorten the period of cooperation and increase understanding, and make the follow-up cooperation more enjoyable. A good work and a successful project are the result of the joint efforts of the design company and the printing company, and are produced through the recognition of the majority of readers. So the creator's creativity must also be soluble in nature, soluble in readers, beyond nature, beyond readers ... In summary, the designer should have certain pre-press knowledge; accurate and accurate pre-press work and humanistic communication and coordination work can fully reflect the design idea through printing, and no longer stay at the moment when the printed product is born Sorry!
