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.
2, output attachment
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.
3, 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 *.pdf.
The PDF files produced in this way can be directly printed by some printing manufacturers. Shanghai printing companies have relatively small documents and can be sent 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: Distiller4's version does not fully reflect some of the hemming effects and needs attention.)
4, font problems
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.
5, the problem of gradient
1 The common problem is this: If the red → black gradient, set the wrong: (M100 → K100) will be difficult to see the middle!
The correct setting should be like this: (M100→M100K100) 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.
