6. Color management issues
Color management is the key and difficult point of CTP technology. The ICC characteristic curve that can accurately reflect the characteristics of the device determines the effect of color management. Therefore, creating the ICC characteristic curve becomes the most important task in color management. In the production practice, the author summarizes the following points that need attention:
1. Keep the printing as steady as possible. Enterprises must establish a set of effective printing standards, especially in controlling the printing density and the increase of network points, and require the operator to resolutely execute the printing process, and control each index within the error range.
2. Make sure the digital proofing device is in normal condition. Such as Agfa's Sharpa series, can use QMS (Qualiy Management System) software to detect and adjust the machine, so that the digital proofing device is always in a normal state, and to ensure consistent print results.
3. The IT8 for measurement must have a clean, oil-free surface, and no creases. This has an important effect on whether the ICC characteristic curve accurately reflects the characteristics of the equipment.
4. In theory, different printing conditions correspond to different ICC characteristic curves. However, for the common impressions of the common prints and human eyes, three ICC characteristic curves reflecting the printing characteristics can be set for the three commonly used papers: coated paper, matte copper and offset paper.
5. With the continuous development of technology, color management software should also be continuously upgraded. From the information fed back by the client, the ColorTune used with the Agfa CTP system has been upgraded to version 4.2, which not only accurately simulates the printing effect, but also is very stable. The effect of color management has been a qualitative leap.

The mouse pad refers to a small pad placed under the mouse. It is mainly designed to prevent the reflection and refraction of the surface of glass and other special materials from affecting the positioning of the mouse sensor. It provides a plane for the mouse sensor system to calculate the movement vector and facilitates people's work. It can be divided into soft cushion and hard cushion according to different materials.
Smoothness
The smoothness is divided into two concepts. Shun: It is mainly used to measure the flatness of the mouse pad surface and whether it can ensure the steady and uniform movement of the mouse. Sliding: generally refers to the smooth feeling of the mouse when it moves on the surface of the mouse pad. The higher the sliding degree, the smoother the mouse movement. In quantitative terms, the mouse is pushed in the same direction and with the same force. The farther it moves, the more slippery it is. The factors that affect the smoothness are the smoothness of the material itself, the shape of the surface texture and the arrangement. This indicator is also the most important factor affecting the performance of the following indicators. Micro operation: Micro operation in FPS games refers to the subtle movement of the mouse in a small range. An important factor that determines the quality of micro operation is the amount of friction when the mouse starts rapidly, which is also called "jerk". The smaller the friction, the lower the difficulty of micromanipulation, and the higher the reverse is. The micro operation of RTS games mostly refers to the number of effective operations that players can complete in unit time. The more times, the lower the error rate, and the stronger the micro operation ability.Positioning ability
Generally speaking, positioning refers to the accuracy of the collimator in FPS games from moving to stopping and completing the aiming process. That is, as the saying goes, "fight where you point.".
Resistance under stress
For example, if you suddenly encounter an enemy at a corner of C, and your first reaction is to quickly move the crosshair to aim and shoot, then the force exerted by your wrist will increase involuntarily due to the tension caused by an emergency, and the range is definitely much greater than when you normally move the mouse, so the pressure on the mouse pad will naturally increase, In this case, the resistance of the cushion itself is the resistance under the stress reaction.
