Question EN: What is drop size in inkjet printing?
问题 CN： 喷墨打印中的 Drop Size 是什么？
Answer EN:
Drop size is the volume of an individual ink droplet ejected by a nozzle. It influences density, detail, smoothness and the amount of ink deposited on the substrate.
答案 CN：
Drop Size 是喷嘴喷出的单个墨滴体积。它会影响图像密度、细节表现、平滑度以及材料表面的墨水沉积量。
Question EN: How does drop size affect One Pass image quality?
问题 CN： 墨滴大小如何影响 One Pass 图像质量？
Answer EN:
Smaller droplets can support fine details and smoother transitions, while larger droplets can provide stronger coverage and density. Industrial systems often balance different drop sizes according to the application.
答案 CN：
较小墨滴有利于细节和渐变表现，而较大墨滴可以提供更强的覆盖和密度。工业系统通常根据应用需求平衡不同墨滴大小。
Question EN: What is grayscale inkjet printing?
问题 CN： 什么是灰度喷墨？
Answer EN:
Grayscale inkjet printing uses different droplet volumes to represent different tonal levels. This can improve smoothness, density control and image quality without requiring every pixel to be printed with the same drop volume.
答案 CN：
灰度喷墨通过不同墨滴体积表达不同的色调级别，可以提高图像平滑度和密度控制能力，而不是让每一个像素都使用完全相同的墨滴体积。
Question EN: Why is grayscale useful for industrial One Pass printing?
问题 CN： 灰度技术为什么适合工业 One Pass？
Answer EN:
Grayscale control allows the system to balance fine detail and ink coverage. This is particularly useful when a production system must combine high throughput with acceptable photographic or graphic quality.
答案 CN：
灰度控制能够在精细细节和墨量覆盖之间进行平衡。这对于需要同时兼顾高生产效率和图像质量的工业 One Pass 系统尤其有价值。
Question EN: Can higher DPI automatically produce better print quality?
问题 CN： 更高 DPI 是否一定意味着更好的打印质量？
Answer EN:
No. DPI is only one component of image quality. Drop placement accuracy, ink behavior, substrate surface, color management, mechanical stability and viewing distance can be equally important.
答案 CN：
不一定。DPI 只是图像质量的一个因素。墨滴落点精度、墨水表现、材料表面、色彩管理、机械稳定性和观看距离同样重要。
Question EN: What causes banding in One Pass printing?
问题 CN： One Pass 中什么原因会导致 Banding？
Answer EN:
Banding can result from nozzle inconsistency, printhead alignment, transport instability, incorrect calibration, ink delivery variation, drying behavior or image-processing errors. Diagnosis should consider the entire print system.
答案 CN：
Banding 可能由喷嘴不一致、打印头对位、材料输送不稳定、校准错误、供墨变化、干燥特性或图像处理问题造成。排查时需要检查整个打印系统。
Question EN: What causes density variation across the print width?
问题 CN： 为什么 One Pass 横向会出现密度不一致？
Answer EN:
Possible causes include printhead stitching, nozzle variation, ink pressure differences, substrate variation, calibration errors and uneven curing or drying. A controlled diagnostic pattern can help identify the source.
答案 CN：
可能原因包括打印头拼接、喷嘴差异、供墨压力变化、材料差异、校准误差以及固化或干燥不均匀。通过标准化测试图可以帮助定位问题来源。
