Decide on the printing method:
Different printing methods produce different effects, and the cost of printing is also different.
Generally speaking, the screen printing is within two colors, and the pressing factory does not add printing costs; the printing costs of two or more colors or four colors are charged separately. Therefore, when all the work has not started, you may wish to consider the cost first, and then decide the design style.
design production:
CD printing technology may not be as good as traditional paper printing.
Due to the limitation of the network cable, the precision of the picture is slightly lost.
However, to overcome technical problems, we can see a variety of ingenious and lovely CD designs.
Many designers know how to use the metal texture of the CD itself, and express the special texture of the CD in the design, giving people a very different feeling. Always refer to the finished CDs produced by different printing methods, not only a good way to increase the printing experience in this area, but also make your design more flexible and creative.
At present, most of the printed CDs are completed on the computer. The following points please note:
The color of the picture and text adopts the printing color, if there is a picture, it is also presented in the CMYK color mode.
Screen printing can be marked with a color code for printing.
The correct CD size and accurate crosshair marks are all very important places.
Output mesh:
After finishing the manuscript, the file will be handed over to the output center to output the 175-line mesh negative film under the film. The printing house will use the mesh film to print and proof. Please do not fold when delivering.
Proof printing:
The net negative film output during color separation cannot be proofed. Please output another set of net positive film under the film for proofing.
Print proofing is an important step for designers to check the graphic content and color deviation.
If the inspection is correct, you can print.
