First, the font problem
① The description method of some font libraries is different, and the overlapped part of the stroke output will be superimposed, be careful!
Paragraph text containing special Chinese and English characters is prone to problems, such as "■, @, ★, ○" and so on.
③ Use the new standard GBK character library to solve the problem of remote word loss.
④ the stroke is too thin font, it is best not to use more than 3 colors of aliasing, such as (C10M30 Y80), etc., similarly, it is not suitable for dark background against white words. In unavoidable cases, it is necessary to edge the anti-white characters, apply the background color of an approximate color or a printing monochrome (usually black K).
Second, the problem of gradual change
① The common problem is this: such as magenta → black gradient, setting errors: (M100→K100) in the middle will be very ugly!
The correct setting should be like this: (M100→M100K100) A careful analysis will understand, and other cases will be similar.
(2) Transparent gradient, is suitable for network graphics method, the finished output can not be, because its spatial mixing mode is RGB, the screen mixing color is too different from printed CMYK, X3 version start effect mixing mode has been CMYK, using 9 to 12 versions of the key attention.
③ The gradient of the black part 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, similarly, the use of pure light black should also be careful.
3. Picture problem
① About the psd file, there is a point to note that you do not do any "destructive operations" after importing it, such as: rotation, mirroring, tilt, etc., because of its transparent mask, the output will produce a broken map.
Or mask, use in coreldraw should also be careful, if necessary, it is better to take the "picture frame accurate clipping" method is safer.
③ Color mode, don't blame me for wordy, this is the old hand also has the wrong hand. All images must be cmyk or grayscale and monochrome bitmap images, otherwise they cannot be output.
4. Output accessories
That is, corner lines, cross lines, color markers and other output accessories, and now the output company services are very good, don't worry about it.
