CorelDraw printed rubber output points analysis

Learn more about some of the CorelDraw printouts' notes and can easily avoid many hassles...

First, the font problem

1 Some font library description methods are different. Overlapped parts of the strokes will appear out of the stack. Be careful!

2 Paragraph texts containing special characters in Chinese and English are prone to problems such as "■, @, ★, ○", etc.

3 Use the new standard GBK font to solve the problem of remote word loss.

4 strokes too thin font, it is best not to use more than 3 colors of aliasing, such as (C10 M30 Y80) and so on, the same reason, it does not apply to dark-colored anti-white characters. Under conditions that cannot be avoided, it is necessary to mark the reversed white character, apply a similar color to the background, or print a single color (usually black K).


Second, the problem of gradual change

1 The common problem is this: If the red → black gradient, set the wrong: (M100 → K100) will be hard to see in the middle! The correct setting should be like this: (M100 → M100 K100) After careful analysis, you will understand, and other situations will be analogized.


2 transparent gradient, is suitable for network graphics methods, grayscale can also be, but the final draft output can not be, because of its spatial mixing mode is RGB, screen mixing color with printing CMYK too much difference, pay attention.


3 The black part of the gradient should not be too low, such as 5% black, because the output has a black overprint option, less than 10% of the black is usually used instead of overprinting, resulting in problems, the same, the use of pure light black also Be careful.

Third, the picture problem

1 With regard to the psd file, one thing to note is that you should not do any "destructive operations" after importing it, such as: rotation, mirroring, tilting, etc. Due to its transparent mask, a broken image will be produced after output.

2 is still a mask, use it in Coreldraw should be careful, if necessary, it is better to adopt the "placed container" method more insurance.

3 resolution and re-sampling Do not do this in corel, "conversion to bitmap" is indeed convenient, but the loss is the color reproduction, to professional point, in the ps to get it.

4 color mode, don't blame me, this is the veteran also has the wrong hand.
All pictures must be cmyk or grayscale and monochrome bitmap, otherwise they cannot be output.

Fourth, output accessories


That is, the output of the corners, color scales, and other things attached to it, and now it seems that the output company services are very good, do not worry too much.


Fifth, prepress inspection

Use PDF files for prepress inspection! Note that it is not directly to print a pdf out of Coreldraw! wrong.


The order is this:
*.cdr → The output is "Encapsulated EPS, which is *.EPS", and Acrobat Distiller will generate EPS for *.pdf.

The PDF files thus produced can be directly printed by some printing manufacturers, and the documents are relatively small, and can be transmitted by E-mail. It is very convenient.

If you have a mistake in your file, you can see it at a glance in the PDF preview! (Note: Distiller 4's response to some edging effects is incomplete and needs attention.)
