Screen dot precision and uniformity: The colors and patterns in printed materials are formed by the overlapping of tiny CMYK four-color dots. Screen dot precision directly affects the fineness of the image. High-quality printing features clear dots without blurring or "smudged" dot adhesion; when magnified, a regular dot pattern is visible. Poor-quality printing may exhibit dot deformation or missing dots, resulting in a blurry image.
Kev txheeb xyuas txoj hau kev: Siv lub khob tsom iav kom pom qhov chaw "Gradient" ntawm cov qauv "ntawm cov qauv, xws li kev hloov los ntawm lub teeb liab mus tsaus liab. Kev ua yeeb yam zoo nkauj zoo nkauj gradients uas tsis muaj cuab yeej thaiv xim thaiv kev tsis ua haujlwm. Saib "cov ntawv me lossis cov kab zoo," xws li cov ntawv hauv qab loj loj 6 lossis kab hauv qab 1pt. Yog tias cov npoo yog du nrog tsis muaj jagged npoo, nws qhia tau muaj zog dot tswj lub peev xwm.

Cov Luam Ntawv Zoo Yuav Tsum Muaj Cov Ntawv Sau Npe<0.05mm, with no ghosting visible to the naked eye. Troubleshooting common issues If samples show missing strokes in text or blurred pattern edges, this may be due to worn printing plates or clogged printheads, indicating inadequate equipment maintenance, which poses a high quality risk during bulk printing. Through sample and case verification, assess whether the channel can consistently produce high-quality output. Technical specifications are theoretical standards, but in actual printing, stability is more important than the quality of a single sample. Some channels can produce high-quality samples, but the quality fluctuates greatly during bulk printing. To assess stability, focus on sample consistency and past cases. Review the channel's similar cases. High-quality printing channels will retain samples from past cases. For example, channels that have printed art catalogs will showcase their color reproduction cases. Channels that have printed textbooks will showcase their case studies on the durability of perfect binding. Check whether the case studies are consistent with your printing category. For example, if you want to print packaging boxes, check whether they have case studies on packaging boxes. Check the quality of the details of the sample case studies, such as the color, clarity, and post-processing mentioned above. Professional channels have clear quality control processes, such as file review and size/color mode checks → proofing confirmation → first-piece inspection for bulk printing → full inspection → pre-packaging re-inspection. If a channel cannot explain its quality control process or states "direct printing without inspection," proceed with caution. Consider the characteristics of different channel types, their quality advantages, and potential pitfalls. Different printing channels have varying equipment and positioning, resulting in differing quality characteristics. Understanding their inherent advantages and common issues enables more targeted evaluations. For example, when evaluating online printing platforms, pay extra attention to whether they support high-definition sample mailing and provide color difference reprint guarantees. When evaluating offline printing factories, it is recommended to inspect the equipment on-site, such as offset printing machine models and whether automatic quality inspection equipment is available. Do not overlook the impact of implicit quality services and after-sales support on the final outcome. Printing quality is not only about the physical product quality but also includes service quality. Professional services can help avoid quality issues in advance, while poor services may result in even high-quality equipment producing subpar products. File Preprocessing Files provided by non-professional users often have issues such as incorrect dimensions or insufficient resolution. High-quality channels offer file review services, proactively identifying issues and assisting with modifications such as adjusting dimensions or improving resolution. If a channel prints directly from an incorrect file, even with top-notch equipment, quality issues will arise. After-sales warranty policies: Even with thorough pre-assessment, quality issues may still arise (e.g., damage during transportation, batch color differences). It is essential to clarify whether the channel supports "free reprinting" if quality issues occur (e.g., significant differences from samples); whether the reprinting timeline is reasonable; and whether there is a designated after-sales contact person.
