Core Additions to the Print Output of Corel Draw

â–  Fonts:

1 Some font library description methods are different. After the overlap of the strokes, the output will be stacked. 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 too young font, it is best not to use more than 3 colors 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 the background color, or print a single color (usually black K).

â–  Gradual issues

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)
Other situations are 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 hybrid mode is RGB, the screen mix color with printing CMYK too different. 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 usually used instead of overprinting, resulting in problems, the same, the use of pure light black but also Be careful

â–  a lot of picture problems

1 About the psd file, one thing to note is that after you import it, do not do any "destructive operations", such as: rotation,
Mirroring, tilting, etc. Due to its transparent mask, a broken image is 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 color reproduction, to be professional, 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 bitmaps, otherwise they cannot be output.
(There are very few people playing monochromatic bitmaps, but playing well is a realm, and it is interesting to discuss it.)

â–  Output accessories

That is, the angular color standard output and other subsidiary things, and now it seems that the output company services are full of good, do not worry too much, really improve the quality of service!

â–  Prepress inspection

Prepress? Oh? Yeah, how do you check?
Look carefully at the following:
Use PDF files for prepress inspection!
Instead of printing a pdf directly with coredraw! wrong.
The order is this: .cdr → Output is "Encapsulated EPS, ie .EPS"
EPS generated by Acrobat Distiller.pdf
The PDF files thus produced can be directly printed by some printing manufacturers, and the file size can be easily transmitted by E-mail:)
If you have a mistake in your file, you can see it at a glance in the PDF preview! (Note that Distiller 4's version does not fully reflect some of the edging effects.)
