Printing quality issues are a common challenge that companies face during the production process. Ensuring consistent and high-quality output is essential, which makes the evaluation and audit of print quality a critical step for every business. But do you understand the four key stages involved in this evaluation? This article will walk you through the complete printing quality assessment process from four different perspectives.
Throughout the entire printing workflow, evaluating the final printed product typically involves several stages:
1. **Customer Evaluation of the Submitted Sample**
When customers receive the initial samples, they take the lead in the evaluation process. They compare the sample to the original artwork or design to determine if it meets their expectations. This stage often involves multiple revisions until the customer is satisfied. Once approved, the signed sample becomes the official reference for the final print. The evaluation covers aspects such as color accuracy, tone reproduction, overprint precision, and image clarity.
2. **On-Site Evaluation and Process Control During Printing**
This stage focuses on real-time monitoring and control within the printing facility. It’s considered the most crucial part of ensuring high-quality output. The process can be broken down into two main steps:
- **Pre-production confirmation**: Before starting the actual print run, operators and quality control personnel check the initial batch of prints. These are compared against the approved customer samples. Some clients even visit the site to sign off on the samples directly, which saves time and reduces back-and-forth communication.
- **Ongoing inspection**: Throughout the printing process, each printed sheet is checked against the standard sample. Any deviations are quickly corrected. To maintain consistency, a certain percentage of the printed sheets must be inspected at regular intervals.
3. **Final Inspection Before Shipment**
Before the finished products leave the factory, a thorough quality check is conducted by the inspection team. They identify and remove any defective or substandard items. Depending on the volume and quality requirements, a full inspection or a statistical sampling approach may be used. Using statistical methods ensures that the evaluation is both efficient and reliable.
4. **External Quality Assessments**
In addition to internal evaluations, the industry frequently conducts external quality assessments. These may involve independent experts who evaluate the printed materials based on industry standards, customer specifications, or other accepted criteria. These assessments help classify the quality of the printed work and ensure compliance with recognized benchmarks.
By following these four stages, companies can maintain consistent quality throughout the entire printing process. Whether it's the customer’s approval, on-site adjustments, final checks, or external audits, each step plays a vital role in delivering a high-quality end product.
