talking about the problems that should be paid attention to in design and production from the perspective of printing. With the continuous intensification of market competition, many enterprises began to set up internal design and production personnel instead of professional advertising companies to complete the design and production work, which can reduce costs to a certain extent and facilitate enterprises to control the design and production process, but at the same time, Because the internal design and production personnel may not be as familiar with prepress requirements as professional institutions, there will be some common sense mistakes. After the completion of design and production, many enterprises will require the printing factory to directly produce films and print, which will transfer the problem to the printing factory

this internal newsletter introduces some basic common sense related to prepress production according to the common problems we have accumulated. These common sense are applicable to end users with internal designers, as well as to start-up advertising companies that are not familiar with printing requirements

1. Design and production is an essential link before printing. The completion of finished printing products must go through four links: design and production, film proofing, machine printing and post-processing, and none of them is indispensable

2. Design and production is the process of using software to mix graphics and text, and it is the previous link of film proofing. Therefore, the requirements of film proofing must be considered in design and production. However, it is not enough to consider only from the perspective of film proofing, because its ultimate goal is to print finished products, so we must also consider design and production from the perspective of printing. Otherwise, some design and production methods are not a problem for proofing, but they will cause considerable problems for printing

the tensile test of the specimen is completed by the action of each unit manipulated by the central console. 3 Design and production can be completed with different software. There is no big difference between the advantages and disadvantages of the software, but only based on the preference and familiarity of the design and production personnel. But generally speaking, in four-color (color) printing, Microsoft Office typesetting cannot be used, because Microsoft Word and excel are word processing software, not professional typesetting software, and cannot be used to output four-color films (red, yellow, blue, black) used in color printing. In color printing, Photoshop, PageMaker, illustrator, freehand, CorelDRAW and other professional typesetting software should be used for typesetting. Quark is another professional typesetting software that has become increasingly popular abroad recently. In black-and-white printing, such as black-and-white books and magazines, word and excel can be used as typesetting software to output monochrome films for printing

4. No matter what software is used, the image file resolution used in typesetting must be more than 300 dpi. The pictures used on the station look very clear, but their resolution is generally only 72 DPI or 100 DPI, which cannot be put into printing. DPI refers to the number of points per inch. The higher the number of points, the clearer the picture. If the image resolution used in typesetting is not 300 dpi, it should be forcibly changed to 300 dpi and changed to the original size to determine whether it is clear and usable

5. The mode of color image must be changed to CMYK mode instead of RGB mode. CMYK is a special mode for printing, and RGB is a special mode for displaying images on the display. If RGB is used to output film, color confusion will appear on the film

6. Confirm that there are all necessary files in the document, and the document already contains image files. Sometimes the image appears to be displayed in the typesetting file, but in fact, the image is missing or the resolution is low. Therefore, it is necessary to confirm that the necessary image has been included and ensure that the image has sufficient resolution. In addition, the necessary fonts should be copied in. If some special fonts are replaced, their effect may be affected, and there may be garbled code

7. In the process of document making, the black characters are all monochromatic black, without chromatic black or four-color black. Therefore, the metal parts of the impact broaching machine should have a certain economic and reasonable surface roughness requirements before plating. This is because if four-color black characters are used, it is very easy to cause inaccurate overprint, which will show other colors in the black characters

8. Conventional size: the size of 16 opening is 210mm x 285mm, and the size of 8 opening is 420mm x 285mm, which is the domestic standard size of 16 opening and 8 opening. In addition, there is an international standard 16 opening size (called A4) of 210mm x 297mm, and the international standard 8 opening size (called A3) of 420mm x 297mm. What we use most is the domestic standard size

9. When output is required after typesetting, 3mm bleeding needs to be set up up up, down, left and right. This is to make allowance for the cutting of printed products. In addition, bleeding should also be set when making up. After making up, you should check whether there are words or drawings with cutting lines, and whether there is enough bleeding left

10. After using illustrator to complete typesetting, you should turn the curve, because all the words after turning the curve will become graphics, and there will be no running words or garbled codes. When using PageMaker to arrange the disk for file copying, it is best to choose the save as command, and press the following link to copy all the files to the disk. Generally, it is not recommended to use Photoshop for mixed arrangement of pictures and texts, but only for image processing, because the words in Photoshop will appear jagged and become blurred during printing

in addition, the following points should be paid attention to after the design

(I) text: 1. The artistic text must be converted into a curve, and it must be checked whether the converted text is shifted, otherwise the word will fall out and the wrong file will be printed; 2. It is forbidden to use gb-2312 fonts, which will appear obvious hollowing out at the intersection of strokes after converting the curve, and this will also happen when founder meihei does not turn the curve; 3. Paragraph text must pay attention to whether all the text in the text box is displayed; 4. The text with text chain and envelope must be converted into curve; 5. For outline words, you must select all fonts and separate the outline together, turn the text to a curve, and delete the outline line; 6. Three dimensional characters must be separated together, and the text must be turned into a curve, and the three-dimensional diagram must be turned into a dot matrix diagram; 7. Words with shadows must be selected together. After separation, the text is converted into a curve, and the shadow is converted into a bitmap; 8. Transparent words must be converted into curves and then re effect; 9. For office software, if the bad font is not reported, you must check it by replacing the font within the compatibility through the option under the tool menu to confirm whether it is bad font. Note: the text in the precise clipping box cannot be found with the search tool

(II). Pictures: 1. The rotated and trimmed pictures must be converted into dot matrix, otherwise the picture will be broken; 2. Pictures with shadows must be converted into bitmap together with shadows; 3. Pictures with filters must be converted to bitmap (pay attention to whether the change of the original image is too large after conversion). Note: the rotated or cut pictures in the precise clipping box cannot be directly converted to bitmap

(III) graphics: 1. Graphics with special effects must be converted to bitmap; 2. The gradient color block must be converted into a dot matrix; 3. When printing with HP 3000, the overprint of graphics must be cancelled

(IV). Bleeding: 1. The printing that needs to be cut must be bleeding and cutting line; 2. The finished products with the size of business cards must have 2mm bleeding, and the front and back cutting lines must be made for those printed on both sides; 3. Finished products larger than the size of business cards must have 3mm bleeding; 4. For machine cutting, 2mm~3mm bleeding must be done (new note: if the background color is the same, it can also be cut across the board); 5. For manual cutting, one size fits all must be done. Note: the finished product cannot be cut normally if it is less than 25mm

(V). Make up 1. The page number sequence must be correct and must be in the middle or outside of the finished product; 2. For documents printed on one side, the layout must be split, nailed and assembled; 3. For documents printed on both sides, the layout must be spelled out; 4. If the books are singular, they must spell the layout of horse riding; 5. If the number of books is even, you must spell the format of 1122; 6. The guest pressure testing machine has a horizontal horizontal pull structure. If there is no page number in the household document, the page number must be added at the position outside the finished product, and if it is not printed, the page number must be handwritten

(VI). Cover 1. The adhesive bound book must be made white at the back of cover 2 and cover 3 and 5mm to the left and right of the back, and 3mm bleeding must be done. 2. Bleeding must not be done at the center line of horse riding; 3. The front cover and back cover of iron ring and rubber strip must be made with 3mm bleeding around. 4. Text hardbound: the width must be added with 3mm on the basis of the finished size of the inner core, the height must not be changed on the basis of the finished size of the inner core, the spine must be added with 5mm on the basis of the thickness of the inner core, the soft back must be made with 10mm, and the bleeding must be made with 10mm~20mm. 5. Iron ring inner hardbound: the width must be added with 6mm on the basis of the finished size of the inner core, The height is unchanged on the basis of the finished size of the inner core, and the spine depends on the thickness of the inner core (consult the post press Security Service Department). The soft back must be 6mm, and the bleeding must be 10mm~20mm; 6. The iron ring is finely assembled on the outside: the width must be added 6mm on the basis of the finished size of the inner core, the height must not be changed on the basis of the finished size of the inner core, and the bleeding must be 10mm~20mm
