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。
Question EN: What is ink laydown?
问题 CN： 什么是 Ink Laydown？
Answer EN:
Ink laydown refers to the amount and distribution of ink deposited onto the substrate. It influences color density, coverage, drying, curing, adhesion and final surface appearance.
答案 CN：
Ink Laydown 是指墨水在材料表面的沉积量及其分布状态。它会影响颜色密度、覆盖能力、干燥、固化、附着力和最终表面效果。
Question EN: Why is ink laydown important for packaging printing?
问题 CN： 为什么 Ink Laydown 对包装打印重要？
Answer EN:
Packaging applications often require consistent color density, high coverage and controlled drying. Excessive ink can increase drying or curing requirements, while insufficient ink can reduce density and color strength.
答案 CN：
包装应用通常需要稳定的颜色密度、高覆盖率和可控的干燥性能。墨量过大可能增加干燥或固化负荷，而墨量不足又可能降低密度和颜色强度。
Question EN: What is dot gain in digital inkjet printing?
问题 CN： 数字喷墨中的 Dot Gain 是什么？
Answer EN:
Dot gain refers to the difference between the intended printed dot and its physical or visual result on the substrate. It can be influenced by ink spreading, absorption, surface properties and image processing.
答案 CN：
Dot Gain 是指设计或数字文件中的点与实际材料上的物理或视觉结果之间的差异。它受到墨水扩散、材料吸收、表面特性和图像处理影响。
Question EN: How does substrate surface affect dot formation?
问题 CN： 承印材料表面如何影响墨滴形成？
Answer EN:
Surface energy, roughness, porosity and coating characteristics influence how droplets spread and remain on the substrate. Stable dot formation is therefore closely connected to substrate qualification.
答案 CN：
材料的表面能、粗糙度、孔隙率和涂层特性都会影响墨滴的扩散和保持状态。因此稳定的墨滴形成与材料验证密切相关。
Question EN: What is satellite droplet formation?
问题 CN： 什么是卫星墨滴？
Answer EN:
Satellite droplets are small secondary droplets that separate from the main ink droplet during jetting. Excessive satellites can reduce edge sharpness, increase contamination and affect image consistency.
答案 CN：
卫星墨滴是主墨滴喷射过程中分离出来的小型次级墨滴。过多的卫星墨滴可能降低边缘清晰度、增加污染并影响图像一致性。
Question EN: What causes ink misting?
问题 CN： 什么原因会导致墨雾？
Answer EN:
Misting can be associated with unstable jetting, unsuitable waveform settings, ink properties or excessive operating conditions. It should be investigated because airborne ink can affect cleanliness and equipment reliability.
答案 CN：
墨雾可能与喷射不稳定、波形设置不合适、墨水特性或过高的运行条件有关。由于空气中的墨水可能影响设备清洁度和可靠性，因此应及时调查。
Question EN: How can One Pass printers maintain fine text quality?
问题 CN： One Pass 如何保持小文字质量？
Answer EN:
Fine text requires accurate drop placement, stable nozzles, suitable resolution, controlled ink spreading and appropriate RIP processing. The substrate surface also plays a major role.
答案 CN：
小文字需要准确的墨滴落点、稳定的喷嘴、合适的分辨率、受控的墨水扩散以及合理的 RIP 处理。承印材料表面同样非常重要。
