Color management is not just about joining the digital drafting system, there are many links. Simply put, color management can be achieved in addition to Soft Proofing and Digital Proofing...

Printing processes with different color gamuts (such as different papers) or printers with Reproduction are as close as possible to make the separation better. Since the color gamut of different printing or printing processes is also different, we should use the color gamut of the process as much as possible to achieve the best results. So the advantage of using Spectral Data (usually LAB data) to select colors in desktop publishing is to maintain a Device Independent color gamut. As long as our printing process or the color gamut of the printer covers the color of this Lab Data, the color can be reproduced accurately.

Photoshop is an important software published on the table, and almost all the images of the printed matter have been modified by photoshop. As a member of ICC, Adobe has added ICC support since Photoshop 5. Now Photoshop 5 has been upgraded to 6, and the color management function has been greatly improved. Compared with the lack of Photoshop5.X, it is really a lot of progress. Let us now. To understanding.

First, basic settings

Now about 80% of Photoshop6's color management settings are set in the Color Settings in the Edit menu. In this Color Settings window, you will notice that there is a setting in the top position first. If you are opening Photoshop 6 for the first time, you will find that Settings is Web Graphics Default. Like Photoshop 5's presets, Adobe presets Photoshop 6 as an online image. Simply put RGB Working Space as sRGB. It should be noted that the gamut of sRGB is small, which is smaller than the color that can be printed by the general CMYK four-color printing process. It is not enough for the printing user to affect the color separation effect in Photoshop. So after installing Photoshop 6, you must change this setting.

When you press Menu next to Settings, you will find that there are ten choices for Custom, which one is what we should use? In fact, each user should have different settings. These ten presets are just a starting point for reference. For example, users in Europe may choose to use Europe Prepress Default as a blueprint.

Then I am in Hong Kong and want to use ICC for color management. How should I set it up?

First, you should select U.S. Prepress Default as the blueprint and make changes. At the same time, the box next to Advance Mode should be selected, otherwise Photoshop6 will not allow us to choose our own ICC profile.

Second, the setting of each Working Space

First of all, RGB Working Space should choose Adobe RGB (1998) as the working color gamut of RGB images. The advantage of Adobe RGB (1998) is that the color gamut is moderately sized, larger than the color gamut of general CMYK printing, and can be used as much as possible in the printing gamut, so it has been widely accepted as a standard before printing.

CMYK Working Space should choose the ICC Profile that we print or draft. This sets the working color gamut of the CMYK image and affects the effect of our Soft Proofing in the display. Therefore, we should select the corresponding glossy paper or newspaper ICC Profile according to the printing process of each image (such as glossy paper, newspaper). If you want to reuse the CMYK settings of Photoshop4 or Photoshop5, you can select Custom CMYK to use The Dot Gain setting of the ink, of course, the color displayed on the display is not as accurate as using the ICC Profile!
