CorelDRAW is a powerful comprehensive software package with graphics, image processing, web page creation, typography, cartoon animation and more.
One of the most widely used applications of CorelDRAW in China is the pre-work of print typography for publications, commonly known as prepress work. Although this is only a part of CorelDRAW's functions, but because we are dealing with other work, we will habitually call other software, such as processing images, we will use Photoshop immediately, we will use Dreamweaver for web pages, and we will use Flash for animation. Etc; so here, I will take a small card as an example, from the layout of the graphics to the drawing of the die model for a brief introduction.
Imposition work:
Before making a print layout, we need to do some analysis on the work object, such as what paper to use, what press to prepare, what process to use, whether to do art processing or special crafts. To save space, I will save it.
1. Open CorelDRAW software and the system will automatically create a “Graph 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 system specified paper, the size is not limited. Then change its size to 125 x 185mm on the property toolbar (the finished size will be 120 x 175mm after folding)
3. Use the pick tool to select the rectangle you just drew. Hold down the Ctrl key and drag the rectangle to the left with the mouse. When a rectangular box with the same original rectangle appears on the screen, the left button does not press the right button, which is to the left of the original rectangle. There is another rectangle like this.
4. Put a picture that has been processed in the box on the right, and add the company information text to the lower part of the box on the left. Form a card style.
5. Select all objects on the card and press Ctrl+G or the Group item under the Arrange menu. Group each object to make it an object. For the convenience of subsequent engineering operations.
6. Select the selection tool and draw a rectangle in a blank space, and adjust the size to 546 x 787mm (positive folio size to represent the paper).
7. Draw a rectangle in the box of the split paper, the size is 526 x 777mm (there is a 5mm bleeding position on the upper and lower sides, 15mm bite on the left side, and 5mm bleeding position on the right side, which means this is the printing version. The core is the effective printing area). Select both rectangles and select Align and Distribute in the Arrange menu. In the pop-up dialog box, select “Right†for the horizontal item and “Medium†for the vertical item to align the two rectangles.
8. Because the right side of the two rectangles are close together after the previous step, we are asking for a distance of 5mm, so we need to adjust. If you adjust it manually, its position is not accurate enough. Select the "Select" tool. When you are not selecting any object, adjust the fine adjustment distance on the property toolbar to 5mm, then select the rectangle of 526 x 777mm and click the left arrow. This rectangle is The other rectangular frame is separated by 5mm so that there is also a 5mm bleeding position on the right side of the paper.
9. Because the finished product 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 we are going to put the cards on the paper. Select the grouped card, then select the inner frame on the paper, select "Align and Distribute" in the "Arrange" menu, select "Left" in the horizontal item, and "Up" in the vertical item to place the card and the inner box. Align the top left corner; select the card, copy and paste, 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 adjustment distance to 250mm, paste the card after selection, press the right direction The arrow, the two cards become the pattern of the arrangement of the pattern, this method is called "head to head" imposition.
Because printing often causes deformation of the paper due to temperature and humidity, in order to minimize the occurrence of plate inaccuracy for this reason, we should try to close the pattern or color complex parts close to the mouth. Bit.排 After the first line above is arranged, then call the “Transform†option in the “Arrange†menu. In the pop-up dialog box, set the vertical distance to the height of the card to 185mm, because we want to shift it down. So set it to -185mm, then select two cards and press "Apply to Remanufacture". Each press will copy a pair of cards down and the position is very accurate. After three consecutive presses, four pairs of eight cards appeared on the layout, and the paper was no longer available.
At this point, the imposition is complete. The specification is spelling eight-mode/positive folio. Although there is some waste of paper, this situation is inevitable. If you want to reduce paper waste, we can use pen and paper to budget before imposition, such as this example. In the version, the size of the printed surface of the card is 500 x 740mm, while the offset of the positive paper is 546 x 787mm, and the facing of the large paper is 597 x 889mm. The size of the special paper is 444 x 634mm, obviously the waste of other paper seems to be even bigger, so it is still appropriate to use positive paper.
Drawing of the die diagram
The completion of the imposition does not mean that the typography work is over. We have another very important job - the drawing of the die diagram.
After each printing process is completed, it has to be divided into individual finished products. For example, the above-mentioned imposition example has to be divided into eight finished cards after printing. It is impossible to cut with scissors when splitting, we have to make another version - the knife template. Of course, in the general printing factory, you don't have to do the knife mold yourself. You only need to draw the knife mold line, then send it to the knife mold factory. The knife mold factory will make the knife version, and then take it back to the beer machine to go to the beer. Press, then remove the paper edge and arrange it neatly to hand over to the customer.
The drawing of the die line is done on the basis of the printing plate. In fact, it is to draw the line of the actual finished product on a plate containing the bleeding position (without filling the color). Let's start the die line. Drawing:
1. The size of the finished card we set above is 120 x 175mm after folding, and it is 250 x 185mm (including bleeding) after unfolding.
2. Use a 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 at The center of the card. Adjust the value of the fine adjustment distance to 0.5mm, select the rectangle you just drew, and press the right arrow to move it to the right by 0.5mm (because the rectangle has been reduced, so if you do not move 0.5mm to the right, two sides will appear. Each was 5.5mm bleeding, but our goal was to have 5mm bleeding on the right and 6mm bleeding on the left). Select the Bezier tool, draw a line with a vertical height of 175mm, and align it vertically to the right of the rectangle. Adjust the trimming value to 120mm. Select the vertical line and click the left arrow. The vertical line divides the rectangle into the right side. 120mm, 119mm on the left. Here, the front is divided into 120mm, and the back is set to 119mm, because it is afraid that the back of the beer will be over the front due to the inaccurate printing of the beer. After the reduction of 1-2mm, it will not worry about the finished product. There is a defect in the open back (that is, the paper on the back side as seen from the front of the card face).
3, select the rectangle (the border is set to a solid line, indicating that you need to cut) and the vertical line (the border is set to a dotted line, indicating that only the indentation is not cut) and grouped into an object, call the "deformation" dialog box in "Arrange" In the "Position" item, set the vertical value to -185mm, the horizontal value to 0, and then click "Apply to Remanufactured Object" three times. The left card die line is basically completed; select four newly created rectangles. In the "Deformation" dialog box, set the horizontal value of 249mm, the vertical item to 0, and then click "Apply to Remanufactured Object" to copy the other four die lines; set the eight card patterns and previous settings. The positioning rectangle of the bite and the bleeding position is removed, and as a result, only eight rectangular frames remain on the paper.
At this point, the printing plate and the die version have been completed, and the follow-up work is to produce the film. Normally, the four color plates of cyan, magenta, yellow and black are printed together with a knife die. If you want to print other processes, you can Need to release another film. Because the filming and plate making belong to the work of the printing room, the prepress work ends here. (The bleeding set here is 5mm for each of the upper and lower sides, and the total amount of bleeding is 10mm. This is because the large sheet of paper is printed to take care of the paper. The plate may be deformed due to the relationship between temperature and humidity. The set position is not allowed. 3mm bleeding is only in the absence of a solution, the general use of 5mm is better. Generally we usually use 3mm bleeding, but if the paper is thicker or packaging, I suggest Use 5mm bleeding, but it is best to do the bleeding cutting line yourself, because the output company is used to help you add 3mm cutting line. This imposition is to try not to waste paper, just open the paper printing, we will provide such a film For others, if you don't make a spell, you have to output a few copies of the film and let the printing house make the imposition.)
Imposition page order
Let's introduce some common layouts: the size is 16 degrees (210╳285mm), and the size after the imposition is 4 degrees. Due to limited time, the corners and cutting lines are not indicated here, only the imposition page mode is provided.
First from the simplest leaflet single-sided introduction: the single page of the 16th opening is usually 216mmx291mm (including bleeding), after the imposition of the four open size is 432x582mm (including bleeding)
Large 16 open single-sided double-sided version: size 216mmx291mm (including bleeding), imposition size 432x582mm (including bleeding)
Four pages, the order is cover, seal two, seal three, back cover. The size is: 213mmx291mm (including bleeding), the size of the imposition is: 426mmx582mm (including bleeding)
Eight pages, the order is cover, seal two, 1, 2, 3, 4, seal three, back cover. The size is: 213mmx291mm (including bleeding), the size of the imposition is: 426mmx582mm (including bleeding), and the binding method is: riding nail.
Twelve pages, the order is cover, seal two, 1, ... 8, seal three, back cover. The size is: 213mmx291mm (including bleeding). The size of the imposition is: 426mmx582mm (including bleeding), and the binding method is: saddle stitch.
On the sixteenth page, the order is cover, seal two, 1, ... 12, seal three, back cover. The size is: 213mmx291mm (including bleeding), the size of the imposition is: 426mmx582mm (including bleeding), the binding method is: riding nails,
Twenty pages, the order is cover, seal two, 1, ... 16, seal three, back cover. The size is: 213mmx291mm (including bleeding). The imposition size is: 426mmx582mm (including bleeding). Binding method is: riding nails.
Twenty-four pages, the order is cover, seal two, 1, ... 20, seal three, back cover. The size is: 213mmx291mm (including bleeding). The imposition size is: 426mmx582mm (including bleeding). Binding method is: riding nails.
Twenty-eight pages, the order is cover, seal two, 1, ... 24, seal three, back cover. The size is: 213mmx291mm (including bleeding). The imposition size is: 426mmx582mm (including bleeding). Binding method is: riding nails.
Thirty-two pages, the order is cover, seal two, 1, ... 28, seal three, back cover. The cover imposition corresponds to the spine. The inner page imposition size is: 426mmx582mm (including bleeding). Binding method is: shrink line binding.
Thirty-six pages, the order is cover, seal two, 1, ... 32, seal three, back cover. The cover imposition corresponds to the spine. The inner page imposition size is: 426mmx582mm (including bleeding). Binding method is: shrink line binding.
Forty pages, the order is cover, seal two, 1, ... 36, seal three, back cover. The cover imposition adds a spine. The inner page imposition size is: 426mmx582mm (including bleeding). Binding method is: shrink line binding.
Forty pages are off, forty pages, the order is cover, seal two, 1, ... 36, seal three, back cover. The cover imposition corresponds to the spine. The imposition size is: 852mmx582mm.
Forty pages are off, the first four are folded, and the last one is small. In addition to the different sizes, the layout of the positive 16 is exactly the same as the 16th opening.
Folding method: Folding page needs 8P one sticker or 16P one sticker. Generally speaking, 8P one sticker is often used in wireless ordering mode, and 16P one sticker is often locked in cable binding (large album). The P number of albums and books is generally a multiple of 4, so when we do the folding, we often have to do one (mainly) to two (special stickers). I have seen a wide company making a book of more than 100 P, using a lot of A4 paper, it is wasteful to fold all the page numbers, no need. In the normal fold, remember that no matter how you fold, the bottom right corner is the first page.
Binding. Generally, it is divided into saddle stitching, flat binding, lock binding, and wireless binding. Our common magazines all use saddle stitching; wire-bound books and wire-loaded items are flat; lock-line binding is often used for large-scale albums, but the binding speed is slow; wireless binding is often used for high-end small albums and thick books. Easy to degumming after repeated folding.
