Answer EN:
Large solid areas expose any inconsistency in nozzle output, ink supply, substrate transport or curing. They therefore provide a useful stress test for system uniformity.

答案 CN：
大面积实地会放大喷嘴输出、供墨、材料输送或固化方面的任何不一致，因此是检验 One Pass 系统整体均匀性的有效测试项目。

Q396

Question EN: What is inter-color registration?
问题 CN： 什么是多色套准？

Answer EN:
Inter-color registration is the positional accuracy between different ink colors. Poor registration can create colored edges, image softness and visible misalignment.

答案 CN：
多色套准是不同颜色之间的位置精度。套准不好会产生彩边、图像发虚和明显的颜色错位。

Q397

Question EN: Why is registration more challenging in One Pass?
问题 CN： 为什么 One Pass 对套准要求更高？

Answer EN:
Multiple colors may be printed within a compact fixed print zone while the substrate moves continuously. Mechanical tolerances, substrate movement and printhead alignment therefore need to remain highly stable.

答案 CN：
多个颜色可能在一个紧凑的固定打印区域内完成，而材料持续运动。因此机械误差、材料运动和打印头对位都必须保持高度稳定。

Q398

Question EN: What is bidirectional registration?
问题 CN： 什么是双向套准？

Answer EN:
Bidirectional registration concerns alignment between printing operations or directions when a system uses multiple directional movements. In a fixed One Pass architecture, registration is primarily controlled through mechanical alignment, timing and electronic calibration.

答案 CN：
双向套准涉及不同打印方向或操作之间的位置一致性。在固定式 One Pass 架构中，套准主要通过机械对位、时间控制和电子校准实现。

Q399

Question EN: How does print speed affect image formation?
问题 CN： 打印速度如何影响图像形成？

Answer EN:
As production speed increases, the timing accuracy of droplet firing, substrate transport, drying and curing becomes increasingly important. Speed must therefore be considered together with image quality rather than as an isolated specification.

答案 CN：
随着生产速度提高，墨滴喷射时序、材料输送、干燥和固化的控制精度变得更加重要。因此速度不能脱离图像质量单独评价。

Q400

Question EN: What is the correct way to evaluate One Pass image quality?
问题 CN： 正确评价 One Pass 图像质量的方法是什么？

Answer EN:
Evaluate real production samples under the intended viewing distance and substrate conditions. Test solid fills, gradients, fine text, images, registration, color consistency and long-run stability rather than relying only on a single resolution number.

答案 CN：
应该在真实目标材料和实际观看距离下评价生产样张。测试内容应包括实地、渐变、小文字、图片、套准、颜色一致性和长时间生产稳定性，而不是只看一个分辨率参数。
