Problems with 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 library to solve the problem of uncommon word loss.

4 too thin font, it is best not to use more than three colors of aliasing, such as (C10M30Y80) 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).

Problems with gradients

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) Under the careful analysis, we will understand, and other situations will be analogized.

2 transparent gradient is suitable for network graphics, grayscale image can also be, but the final draft output can not be used, because the space blending mode is RGB, the screen mixed color is too different from the printing CMYK. 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, use pure light black also have to be careful .

Picture issue

1 About the psd file, there is one point to note: that is, after you import it, do not do any "destructive *", such as: rotation, mirroring, tilt, etc., due to its transparent mask relationship, the output will produce a broken map.

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 bitmap, otherwise they cannot be output. (There are few people playing monochromatic bitmaps, but playing well is a realm.)

Output attachment

That is, the angular color standard and other outputs are affiliated. Now, it seems that the output of the company's services is full, and it does not take too much.

Prepress

Use PDF files for prepress inspection! Pay attention not to print a pdf directly using coredraw! this is not right.

The order is this: *.cdr → output is "encapsulated EPS, ie *.EPS"

EPS generated by Acrobat Distiller*.pdf

The resulting PDF file can be directly printed by some printing manufacturers, and the file size can be E-mailed.
