Prepress technology is really very important, if we didn't deal with the problem before printing, also can't go to theprinting of high quality printing products, Longyin Group in this article summarizes ten before printing for you to pay attention to the problem.
The 1, copywriting and effective content arrangement should be laid tangent distance more than 3 mm, in order to avoid cutting words were cut to.
2, design good file fragments of text should be converted into curve, to avoid loss due to can't find the font when output plate making text or garbled words.
Three words, text input, please do not use the system, can cause strokes alternating with white node.Change the fonts into curves after magnification, if there is a white node in writing strokes crisscross place words illustrate this font is used to print, system or need to switch to other fonts.
4, avoid words in PHOTOSHOP software and bitmap type after printing, bitmap text will appear different degree of fuzzy printing.
5, all the input, or to draw the line color piece of graph, the setting of the wire frame thickness not less than 0.1 mm, printing the finished product will have a break or won't be able to present.
6, any gradient objects do not set "edge width", published by CTP system interpretation is different, can cause insufficient gradually layer edge coloring.
7, the picture did not deal with or image format error will cause the lost figure, RGB images or other non CMYK32 bit below pictures of 300 dpi will cause discoloration, fuzzy.When using pictures to accurately cut frame, please check if there is a lock to accurately cut figure box, such as unlocked.All objects will be lost in drawing frame accurately cut.
In 8, Coreldraw, when applied to the gradient in the puzzle and rotate easily leads to the gradient layer direction is wrong.
These are the problems of prepress design should take note, ready at eight o 'clock this we would have had a smooth printing a lot, also the chance of error is less.
