Prepress software problems and output problems, tips II

Second, the common trap in the output

Because there are too many traps in the output, we have to be very careful and fall into the trap of the computer with little care. Here are the traps I often encounter in my work:

RGB graph not converted to CMYK

Consequences: Most software (such as FreeHand, PageMaker, etc.) will not separate RGB images. If you mistakenly use an RGB image, the resulting color separation film will either have a map on the black plate only, and the rest of the color plate image will be partially blank, or have equivalent grayscales on the four color plates. Solution: Don't forget to convert RGB to CMYK before outputting. Tip: It is difficult to see whether it is RGB or CMYK from the file name or file icon. It is too much trouble to open them one by one. For TIFF images, it can be seen clearly by linking the information. As for the EPS image, it can only be checked one by one.

FreeHand fonts use Heavy (heavier), PageMaker fonts use Bold (bold)
Consequences: If the Chinese fonts used in FreeHand use Heavy, most cases will be ambiguous; while in Chinese in PageMaker Bold, it will certainly be overlapping words with teeth. Again, other font effects in PageMaker will cause problems. Solution: Try to avoid using the above effect. If the font needs to be bold, the corresponding bold Chinese characters should be used, such as selecting the bold typeface or bold typeface. If there is no corresponding bold text, you can use Fill and Stroke in FreeHand.

FreeHand using Fill and Stroke

Consequences: Use Fill and Stroke to make fonts bolder, or to make words with different colors. However, improper use can result in stencils, or the edges are too thick, and the colors of the characters themselves are crushed. Solution: 3% principle (original font size multiplied by 3%). If the font itself is bold, the proportion should be smaller.

Misuse of JPEG compression format
Consequences: There is an image on the screen and the output is missing. Solution: In the PhotoShop software, save it back to TIFF or EPS format and go back to vagemaker to reconnect.

The big picture is reduced to a small circle
Consequences: The time that affects the output. Solution: In the typesetting software, it is convenient to zoom the graph, but the cost is multiple or several times the output time, so be sure to set the size and resolution in image processing software (such as Photoshop), and then reset the layout software.

Section head empty, table with spaces
Consequences: Qualified text or forms on the screen are missing. Solution: If you use PageMaker or QuarkXPress, the software itself has a very good indentation positioning function, you can make a very professional and very neat form. As for the paragraph head, it should be set in the row.

Borrow DCS format
Consequences: Different situations have different consequences. 1. The black-and-white print has a picture, but there is no picture on the output film; 2. A black-and-white drawing when printed in color; 3. Although color printing is a color image, it is rough. Solution: The reason for l is that only the main file is exported but no color separation file. The reason for this is that the main file contains only the grayscale image of the low resolution image. The reason is that the main file contains the low-resolution color image. . Tip: Do not use the DCS format unless you have a particularly good reason or have a good understanding of DCS.

Misuse of "Pattern" Fill in FreeHand
Consequences: FreeHand has a pattern fill that fills a regular pattern with a regular pattern. This type of pattern is latticed, and the Level 1 RIP image-setter provided earlier does not support such a padding output, and the Levell 11 imagesetter can output. But one thing to note is that you can't set colors outside the field for it. If you try to set a light color of C10%Y10%, although it is displayed on the screen, the output must be 100% dark green for CY! Solution: Unless not used.

Jumping words - There are two main reasons why jumping occurs in the output: one is the position of the word after the replacement of the font, and the other is the space between the word and the word. The only way for the former case is to re-adjust the position of the word after the font is changed, and there are two ways to solve the latter: first, divide the word into two parts and place it in its original position; The solution is to use the True Type font. After the position of the word and figure is determined, the word will be Outlined, but it should be noted that the space between the words must be English space, otherwise after the Outline, the empty position will appear. mouth".

Bottom black and white figure
Storing graphs in Grayscale as TIFF images in Photoshop and placing them into Freehand is problematic - if a grayscale graph is selected under a black overprint, then the white part of the Grayscale graph becomes a color patch or if it is underneath. The corresponding part of the basemap, the reason for this problem is that the Freescale is placed in Photoshop's Grayscale map default fill color is K100, in the choice of black overprint, the white part is considered to be CMYK are zero, which naturally reveals its color The version of the color, for this case, there are two ways to solve: First, in Photoshop, the Grayscle into CMYK, in the Channel dialog CMYK total Channel selec all, copied to the Channel Black, and then delete the C, M, Y three Channel in the image; Another approach is in Freehand, the Grayscale map fill to Y1, K100, so that when the choice of black overprint will not be a problem.

Output low accuracy map
Pagenaker puts in a graph and asks if you include this graph or not. In the case of a disassembled EPS image, it contains only the header. Its interpretation is very low, and its megabyte is less than PageMaker's threshold. PageMaker automatically includes this file header and no longer links the remaining DCSs. In the case of a color file, the output will become a low-accuracy map. Similarly, the diagrams contained in the PageMaker file are modified in other software, and PageMaker does not relink, and the old ones that have not been modified are still coming out.
