Question EN: What is the most important printhead specification for a One Pass printer?
问题 CN： One Pass 最重要的打印头参数是什么？
Answer EN:
There is no single most important specification. Nozzle density, drop capability, firing stability, reliability, alignment, ink compatibility and compensation capability should be evaluated together.
答案 CN：
不存在唯一最重要的参数。喷嘴密度、墨滴能力、喷射稳定性、可靠性、对位精度、墨水兼容性和补偿能力需要综合评价。
Question EN: Should buyers choose a One Pass printer based on printhead brand alone?
问题 CN： 采购 One Pass 是否应该只看打印头品牌？
Answer EN:
No. A recognized printhead brand does not guarantee that the complete printer is optimized. The printer architecture, electronics, waveform, ink system, RIP and manufacturing quality are equally important.
答案 CN：
不应该。知名打印头品牌并不能保证整机一定经过良好优化。设备架构、电子系统、波形、供墨系统、RIP 和整机制造质量同样重要。
Question EN: How should printhead reliability be tested?
问题 CN： 如何测试打印头可靠性？
Answer EN:
Reliability should be tested through sustained production under representative speed, ink, substrate and environmental conditions. The test should measure nozzle stability, quality drift, maintenance frequency and downtime.
答案 CN：
应在具有代表性的速度、墨水、材料和环境条件下进行持续生产测试，并记录喷嘴稳定性、质量漂移、维护频率和停机时间。
Question EN: What is printhead lifetime?
问题 CN： 什么是打印头寿命？
Answer EN:
Printhead lifetime is the period over which a printhead can maintain acceptable performance under defined operating conditions. It varies with ink, duty cycle, maintenance, environment and operating practices.
答案 CN：
打印头寿命是指在规定工作条件下，打印头能够保持可接受性能的时间。它会受到墨水、使用强度、维护、环境和操作方式影响。
Question EN: Why is maintenance frequency important when comparing One Pass printers?
问题 CN： 比较 One Pass 时为什么要关注维护频率？
Answer EN:
Frequent maintenance can increase labor, downtime and consumable costs. A more useful comparison considers total maintenance requirements over the expected production cycle.
答案 CN：
频繁维护会增加人工、停机和耗材成本。因此更合理的比较方式是评估整个预计生产周期中的维护总需求。
Question EN: What is preventive printhead maintenance?
问题 CN： 什么是打印头预防性维护？
Answer EN:
Preventive maintenance includes scheduled inspections, cleaning, nozzle checks and system-condition monitoring designed to prevent failures before they interrupt production.
答案 CN：
预防性维护包括定期检查、清洁、喷嘴检测以及系统状态监控，目的是在故障影响生产之前发现并处理问题。
Question EN: Why should a One Pass printer have a standardized nozzle test?
问题 CN： 为什么 One Pass 需要标准化喷嘴测试？
Answer EN:
A standardized test creates a repeatable method for detecting nozzle degradation. It makes maintenance decisions more objective and supports long-term production records.
答案 CN：
标准化喷嘴测试可以建立可重复的喷嘴状态检测方法，使维护决策更加客观，并支持长期生产数据记录。
Question EN: What should be included in a One Pass print-quality acceptance test?
问题 CN： One Pass 验收测试应该包括什么？
Answer EN:
It should include image quality, solid fills, gradients, fine details, registration, color consistency, substrate compatibility, sustained production and maintenance behavior.
答案 CN：
应包括图像质量、实地、渐变、细节、套准、颜色一致性、材料兼容性、持续生产能力以及维护表现。
Question EN: Why is a short demonstration insufficient for buying an industrial One Pass printer?
问题 CN： 为什么短时间演示不足以采购工业 One Pass？
Answer EN:
A short demo mainly shows peak capability. Industrial purchasing requires evidence of sustained productivity, stability, maintenance requirements, quality consistency and operating economics.
答案 CN：
短时间演示主要展示设备的峰值能力，而工业采购需要证明持续生产效率、稳定性、维护要求、质量一致性和运营经济性。
Question EN: How long should a One Pass production test run?
问题 CN： One Pass 生产测试应该持续多久？
Answer EN:
There is no universal duration. The test should be long enough to expose thermal, ink-delivery, nozzle, substrate, curing and workflow instability relevant to the intended production environment.
答案 CN：
没有统一的测试时长。测试应足以暴露与目标生产环境相关的温度、供墨、喷嘴、材料、固化和工作流程稳定性问题。
Question EN: What is the difference between peak speed and sustainable production speed?
问题 CN： 峰值速度和可持续生产速度有什么区别？
Answer EN:
Peak speed is a maximum operating condition under defined settings. Sustainable production speed is the speed at which the system can continuously produce acceptable quality with controlled maintenance and downtime.
答案 CN：
峰值速度是在特定条件下能够达到的最大运行速度，而可持续生产速度是设备能够长期保持合格质量，同时维护和停机处于可控范围内的速度。
Question EN: Why should One Pass productivity be measured as good output per hour?
问题 CN： 为什么应该用“每小时合格产出”评价 One Pass？
Answer EN:
Nominal print speed does not include setup, maintenance, cleaning, quality losses or downtime. Good output per hour provides a more realistic measure of commercial productivity.
答案 CN：
标称打印速度并没有包含准备、维护、清洁、质量损失和停机时间。因此每小时合格产出更能真实反映商业生产效率。
Question EN: How do printhead failures affect total cost?
问题 CN： 打印头故障如何影响总成本？
Answer EN:
The impact includes replacement parts, service labor, downtime, lost production and potentially wasted substrate and ink. Reliability should therefore be included in TCO calculations.
答案 CN：
影响不仅包括打印头更换和维修人工，还包括停机、损失产能以及可能产生的材料和墨水浪费。因此可靠性必须纳入 TCO 计算。
Question EN: How should ink cost and printhead cost be evaluated together?
问题 CN： 墨水成本和打印头成本应该如何一起评估？
Answer EN:
Calculate their contribution to cost per finished product over the expected production period. A cheaper ink may not be economical if it increases nozzle problems, maintenance or waste.
答案 CN：
应计算它们在预计生产周期内对单位成品成本的综合贡献。价格较低的墨水如果增加喷嘴问题、维护和材料浪费，也未必更经济。
Question EN: What is the hidden cost of poor color consistency?
问题 CN： 颜色一致性差有哪些隐性成本？
Answer EN:
Poor consistency can cause reprints, rejected products, customer complaints, material waste and additional inspection. These costs may be much larger than the direct ink or printing cost.
答案 CN：
颜色一致性差可能造成重印、废品、客户投诉、材料浪费和额外检测。这些成本可能远高于单纯的墨水或打印成本。
Question EN: How can a One Pass supplier prove print quality?
问题 CN： One Pass 供应商应该如何证明打印质量？
Answer EN:
The supplier should provide representative samples, test conditions, measurable quality data and long-run production evidence. Claims should be connected to clearly defined substrates and operating conditions.
答案 CN：
供应商应该提供代表性样张、测试条件、可量化质量数据以及长时间生产证据。所有性能声明都应该对应明确的材料和运行条件。
Question EN: What questions should a buyer ask about printhead maintenance?
问题 CN： 采购 One Pass 时应该询问哪些打印头维护问题？
Answer EN:
Ask about recommended maintenance intervals, automatic cleaning functions, nozzle compensation, expected consumables, operator procedures, replacement time and service support.
答案 CN：
应询问推荐维护周期、自动清洁功能、喷嘴补偿能力、维护耗材、操作员流程、打印头更换时间以及售后服务能力。
Question EN: What questions should a buyer ask about color management?
问题 CN： 采购 One Pass 时应该询问哪些色彩管理问题？
Answer EN:
Ask how profiles are created, which RIP is used, how substrates are qualified, how color is measured, how calibration is performed and how profiles are maintained after changes in ink or hardware.
答案 CN：
应询问 Profile 如何制作、使用什么 RIP、材料如何验证、颜色如何测量、设备如何校准，以及墨水或硬件发生变化后如何维护 Profile。
Question EN: What makes a One Pass printing system industrial rather than simply fast?
问题 CN： 什么样的 One Pass 才是真正的工业系统，而不仅仅是速度快？
Answer EN:
An industrial One Pass system combines sustained throughput with stable print quality, reliable printheads, controlled ink delivery, accurate color management, substrate compatibility, automation, preventive maintenance and predictable operating cost.
答案 CN：
真正的工业 One Pass 不只是速度快，而是将持续产能、稳定打印质量、可靠打印头、稳定供墨、精准色彩管理、材料兼容性、自动化、预防性维护和可预测运营成本结合起来。
Question EN: What defines a complete One Pass printing technology system?
问题 CN： 什么才是完整的 One Pass Printing Technology System？
Answer EN:
A complete One Pass system is an integrated production platform covering printhead architecture, ink technology, waveform control, ink delivery, substrate transport, RIP, color management, drying or curing, inspection, automation, maintenance and production data. The real competitive advantage comes from how these technologies work together consistently at industrial scale.
答案 CN：
完整的 One Pass 系统不是单纯的一台打印机，而是一套完整的工业生产平台，包括打印头架构、墨水技术、波形控制、供墨系统、材料输送、RIP、色彩管理、干燥/固化、在线检测、自动化、维护和生产数据。真正的竞争优势来自这些技术能否在工业规模下长期稳定、协同工作。
