What is vector color separation?
The method in which separation of colors into two or more different components is known as vector color separation. And the separations are those films which created separate plates. Full color photograph divided into four different colors. The reason of this is to separate four primary colors in an image. I-e cyan, magneta, and yellow. The method of color separation can be achieved photographically, electronically, or at the desktop.
If, a separate plate is designed for specific point color. When inked with a suitable shade and printed in the registry with one another, certain colors link to represent the new artwork.
Preparations of artwork for color separation:
- Fixed up color control, and calibrate your screen and choosing an Illustrator Color Background
- Light evidence of how the shade will look on the designated output method. Select Window > Separations Preview and notice carefully how color separation looks
- If the following document is in the form of RGB, Select File > Mode of the color of the document > CMYK Color to change it to CMYK Mode.
- If there are combinations of colors in your artwork, Correct them as much as you can so that they print evenly
- If your artwork needs confining, fixed up proper overprinting, and catching
- If your artwork includes sections of natural, extending colors, show which regions will be touched by crushing and see which crushing choices you need to practice
Modes of color separations:
There are two basic methods of creating color separations in Illustrator. The most significant variation among both the methods is, in which mode color separators are created.
In the popular host-based, workflows which are separated previously and then Illustrator create the postscript data file. Every separation needs new documents. And afterward, send this information to the output device.
In the more modern RIP supported workflow, the current production of PostScript RIPs makes color separations, crushing, and also color control on the RIP. This method uses more limited time for Illustrator to create the file and reduces the number of data forwarded for each assigned copy job.
Exposure of image and emulsion:
Emulsion applies to the photosensitive film on a piece of paper. This means that nature in the image is clear i-e, “best version. When the photosensitive film is down it indicates that type is not clear when the photosensitive film is backing apart from you. While printing usually the result of printing is right reading means the print is clear, whereas images printed on film are usually printed Down (Right Reading).
To determine whether you are staring at the emulsion surface or the no emulsion surface further related to as the center; consider the last layer below fluorescent light. One surface seems more polished than the opposite side. The dark surface is the emulsion side; the bright side is the bottom and support.
Image exposure leads to whether artwork copies as a positive or negative image. Print shops need negative transparency in the United States and positive transparency in Europe and Japan. If you are uncertain of which image representation to practice, ask your print shop.
