Knowledge summary of prepress assignment layout tutorial
CorelDRAW is a powerful and comprehensive software package with various functions such as graphics drawing, image processing, web page production, printing and typesetting, cartoon animation and so on.
One of the most widely used areas of CorelDRAW in China is the preliminary work applied to the printing and typesetting of publications, commonly known as prepress work. Although this is only a part of CorelDRAW's functions, because we are dealing with other tasks, we will also habitually call other software, such as processing images, we will immediately use Photoshop, Web pages will use Dreamweaver, animation will use Flash, etc. Wait; so here, I will take a small card as an example to briefly introduce from the typesetting of the graphics to the drawing of the die pattern.
Imposition work:
Before printing and typesetting, we must first analyze some of the work objects, such as what paper to use, what printing machine to prepare, what process to use, whether to carry out any art processing or any special process, etc. In order to save space, I will save it.
1. Open the CorelDRAW software, the system will automatically create a "graphic 1" file.
2. Select the fifth place from the toolbox on the left-the rectangle tool, draw a rectangle in the blank space next to the paper specified by the system, and the size is unlimited. Then change its size to 125 x 185mm on the property toolbar (the finished size will be 120 x 175mm after being folded in half)
3. Use the selection tool to select the rectangle you just drawn, hold down the Ctrl key and drag the rectangle to the left with the mouse. When a rectangular frame that is the same as the original rectangle appears on the screen, hold down the left button and press the right button. A rectangle similar to it appears.
4. Put a processed picture in the right frame, and add the company information text in the lower half of the left frame. Form a card style.
5. Select all the objects on the card and press Ctrl + G or the "Group" item under the "Arrangement" menu. Group each object to make it an object. In order to facilitate the operation of subsequent projects.
6. Select the selection tool, draw a rectangle in a blank space, and adjust the size to 546 x 787mm (positive folio size, which means paper).
7. Draw another rectangle in the box on the folio, with a size of 526 x 777mm (5mm hemorrhage is left on the upper and lower sides, 15mm bite is left on the left, and 5mm is left on the right, which means this is a printed version The core is the effective printing area). Select both rectangles, select "Align and Distribute" in the "Arrangement" menu, check "Right" for the horizontal items and "Middle" for the vertical items to align the two rectangles.
8. After the previous step, the right sides of the two rectangles are close together, but we require a distance of 5mm, so we need to adjust. If it is adjusted manually, its position is not accurate enough. Select the "Select" tool, when Baozheng does not select any object, adjust the fine-tuning distance on the property toolbar to 5mm, and then select the rectangular frame of 526 x 777mm, click the left arrow, this rectangular frame is The other rectangular frame is separated by 5mm, so that there is also a bleeding position of 5mm on the right side of the paper.
9. Because the finished size of the card is 120 x 175mm after folding, plus the bleeding position, the full size of the design draft is 250 x 185mm. Now our next step is to put the card on the paper. Select the grouped cards, then select the inner frame on the paper, select "Alignment and Distribution" in the "Arrangement" menu, check "Left" for the horizontal items, and "Up" for the vertical items. Align in the upper left corner; select the card, copy and paste, and then adjust the rotation value to 180 in the property bar to flip it, so that the pattern parts of the two cards are opposite; adjust the fine-tuning distance to 250mm, paste the card after selection, click the right direction Arrows, two cards become pattern to pattern arrangement, this method is called "head-to-head" imposition.
Because printing will often cause expansion and contraction of the paper due to the relationship between temperature and humidity, in order to minimize the occurrence of inaccurate registration due to this reason, we should try to place the parts with complicated patterns or colors close to the bite. Bit. Once the first line above is lined up, then call the "Transform" option in the "Arrange" menu, in the pop-up dialog box, set the vertical distance to the card's height value of 185mm, because we want to move it down, So set it to -185mm, then select two cards and press "Apply to Reworked Objects". Each press will copy down a pair of cards, and the position is very accurate. After three presses, four pairs of eight cards appeared on the page, and the paper could no longer be arranged.
At this point, the imposition is complete. The specification is to spell eight-mode / positive folio. Although there is some wasted paper, this situation is inevitable. If we want to reduce the waste of paper, we can use pen and paper budget before imposition, such as this example The size of the printed surface of the card after the eight-piece format is 500 x 740mm, while the facing size of positive paper is 546 x 787mm, the facing size of large paper is 597 x 889mm, and the facing size of special paper is 444 x 634mm, obviously the waste of using other paper seems to be greater, so it is appropriate to use positive paper.
Drawing of the die pattern
The completion of the imposition does not mean the end of the typesetting work, we have another very important work-the drawing of the knife pattern.
After the printing process is completed, each print must be divided into finished products. For example, the imposition example above, after finishing the printing, it must be divided into eight finished cards. It is impossible to use scissors to cut when dividing, we have to produce another version-knife template. Of course, in general printing factories, you don't need to make the knife mold yourself. You only need to draw the knife mold line, and then send it to the knife mold factory. The knife mold factory will make the knife plate, and then take it back to the beer machine to beer Press it, and then remove the paper edge and put it neatly to deliver it to the customer.
The drawing of the die line is done on the basis of the printed version, in fact, the actual size of the finished product is drawn on a layout containing a bleeding site (no color is required), let's start the die line The drawing:
1. The finished card size we set above is 120 x 175mm after being folded in half, and 250 x 185mm after being unfolded (including bleeding).
2. Use the rectangle tool to draw a rectangle with a size of 239 x 175mm. Select the rectangle and then select the card in the upper left corner of the printing plate, press the "C" key to align vertically, press the "E" key to align horizontally, the rectangle is in The center of the card. Adjust the fine-tuning distance value to 0.5mm, select the rectangle just drawn, and click the right arrow to move it to the right by 0.5mm (because the rectangle has done a reduction action, so if you do not move 0.5mm to the right, both sides will appear Each is 5.5mm bleeding, but our goal is to have 5mm bleeding on the right and 6mm bleeding on the left). Select the Bezier curve tool, draw a line with a vertical height of 175mm, and align it vertically to the right of the rectangle, adjust the fine-tuning value to 120mm, select the vertical line, click the left arrow, the vertical line will divide the rectangle into the right 120mm, 119mm on the left. Here, the front is set to 120mm, and the back is set to 119mm, because the back is beyond the front due to inaccurate registration after the beer press on the beer machine. After 1-2mm reduction, it will not worry about the finished product. There is a defect of open back (that is, the paper on the back can be seen from the front of the card surface).
3. Select the rectangle (the border is set to a solid line, indicating that it needs to be cut) and the vertical line (the border is set to a broken line, which means that only the indentation is not cut) and the group is an object, and the "deformation" dialog box in the "arrangement" is called , Set the vertical value to -185mm and the horizontal value to 0 in the "Position" item, and then click "Apply to Remanufactured Objects" three times, the card die line on the left is basically completed; select the four newly created rectangles , Set the horizontal value of 249mm in the "Transformation" dialog box, and set the vertical item to 0, and then click "Apply to Reworked Objects" to copy another four die lines; combine the eight card patterns with the previous settings The positioning rectangular frame of the bite and bleeding position was removed, and as a result there were only eight rectangular frames left on the paper.
At this point, the printing plate and the knife template are completed. The follow-up work is to produce a film. Normally, four color films of cyan, magenta, yellow, and black are printed and an additional knife die is added. Need another movie. Because film production and plate making belong to the work of the printing room, the prepress work ends here. (The bleeding set here is 5mm on the upper and lower sides, which is a total of 10mm of bleeding. This is because the printing of large sheets of paper should take care of the paper. The paper may be deformed or deformed due to the relationship between temperature and humidity. The position of the set is not accurate. The bleeding of 3mm is only when there is no way. The 5mm is generally better. Generally, we usually use the bleeding of 3mm for design, but if the paper is thick or packaging, I suggest Use 5mm bleeding, but it is best to make the bleeding cutting line yourself, because the output company is used to help you add a 3mm cutting line. This imposition is to try not to waste paper, printing on the paper in the open, we provide such a film For others, if you do n’t make an imposition, you need to output a few copies of the film and let the printing house make the imposition.)
On the order of imposition pages
First introduce some commonly used layouts: the size is based on a large degree of sixteen (210? 285mm) as an example, and the size after imposition is a large degree of four. Due to limited time, corner lines and cutting lines are not specified here, only the page layout method is provided.
Let's start with the simplest one-page single-page introduction: the single-page 16-degree size is usually 216mmx291mm (including bleeding), and the four-size size after imposition is 432x582mm (including bleeding)
Dadu 16 open single page double-sided layout: size 216mmx291mm (including bleeding), imposition size 432x582mm (including bleeding)
Four pages, the order is front cover, cover two, cover three, back cover. Size: 213mmx291mm (including bleeding), imposition size: 426mmx582mm (including bleeding)
Eight pages, the order is front cover, cover two, 1, 2, 3, 4, cover three, back cover. The size is: 213mmx291mm (including bleeding), the imposition size is: 426mmx582mm (including bleeding), and the binding method is: riding nails.
Twelve pages, in the order of front cover, cover two, 1, ... 8, cover three, back cover. The size is: 213mmx291mm (including bleeding). The imposition size is 426mmx582mm (including bleeding), and the binding method is: riding nail.
Sixteen pages, in the order of front cover, cover two, one, one, two, one cover three, back cover. The size is: 213mmx291mm (including bleeding), the imposition size is: 426mmx582mm (including bleeding), the binding method is: riding nail,
Twenty pages, in the order of front cover, cover two, one, sixteen, cover three, back cover. The size is: 213mmx291mm (including bleeding). The imposition size is: 426mmx582mm (including bleeding). The binding method is: saddle stitch.
Twenty-four pages, the order is front cover, cover two, 1, ... 20, cover three, back cover. The size is: 213mmx291mm (including bleeding). The imposition size is: 426mmx582mm (including bleeding). The binding method is: saddle stitch.
Twenty-eight pages, the order is front cover, cover two, 1, ... 24, cover three, back cover. The size is: 213mmx291mm (including bleeding). The imposition size is: 426mmx582mm (including bleeding). The binding method is: saddle stitch.
Thirty-two pages, the order is front cover, cover two, 1, ... 28, cover three, back cover. The cover imposition will add the spine accordingly. The inner page imposition size is: 426mmx582mm (including bleeding). The binding method is: shrink line binding.
Thirty-six pages, in the order of front cover, cover two, 1, ... 32, cover three, back cover. The cover imposition will add the spine accordingly. The inner page imposition size is: 426mmx582mm (including bleeding). The binding method is: shrink line binding.
Forty pages, in the order of front cover, cover two, 1, ... 36, cover three, back cover. The cover imposition will add the spine accordingly. The inner page imposition size is: 426mmx582mm (including bleeding). The binding method is: shrink line binding.
Forty pages apart, forty pages, the order is front cover, cover two, 1, ... 36, cover three, back cover. The cover imposition will add the spine accordingly. The imposition size is: 852mmx582mm.
Forty pages apart, the first four folded hands are major flips, and the last one is a minor flip. Except for the difference in size, the layout of the positive degree 16 is the same as that of the large degree 16.
Folding method: Folding depends on whether 8P one sticker or 16P one sticker is required. Generally speaking, 8P one sticker is often ordered by wireless, and 16P one sticker is often locked by wire (large picture album). The P number of picture books and books is generally a multiple of 4. Therefore, when we make folding samples, we usually only need to make one type (main stickers) to two types (special stickers). I once saw a wide company make a picture book of more than 100 P, used a lot of A4 paper, and it was a waste to fold out all the page numbers. It is unnecessary. When folding normally, remember that no matter how you fold, the lower right corner is the first page.
Binding. It is generally divided into saddle stitching, flat stitching, thread binding and wireless binding. Our common magazines all use saddle stitching; wire binding and wire binding are flat binding; wire binding is often used for large picture books, which are firm, but the binding speed is slow; wireless binding is often used for high-end small picture books and thick books It can be easily degummed after being folded many times.
