Printing errors are an unavoidable reality in the industry, especially for professionals who have spent years in the field. Customers, on the other hand, often find themselves confused or dissatisfied with the final product, not fully understanding the technical limitations involved. This leads to communication breakdowns and disputes, with customers perceiving the printing factory as uncooperative or unreasonable, while the factory sees the customer as overly demanding or difficult to work with.
To bridge this gap, it's essential to understand the objective errors that occur during the printing process. These are not due to negligence or poor management but are inherent to the technology and materials used. Here’s a closer look at some of the most common issues:
1. **Typesetting Errors**
Typesetting is a critical step where text layout is determined using design software. While the printing house usually asks customers to confirm the layout before proceeding, sometimes time constraints or trust lead customers to delegate this responsibility. If mistakes occur—like typos or formatting issues—it can cause confusion. To prevent this, we recommend signing off on proofs before production. Some companies even add disclaimers like “This information is for reference only†to reduce liability.
2. **Film and Proofing Errors**
The accuracy of film output can vary due to differences in film batches or laser image setters. When films are replaced, overprint issues may arise. Proper proofing requires controlling equipment, materials, and standards—such as ink consistency, paper type, and density values. Even with careful control, slight variations between proofs and actual prints are normal.
3. **Color Discrepancies**
Color errors can be divided into three types: mismatch between printed material and proof, inconsistency between front and back of the same batch, and deviation from the actual color. These are influenced by ink, paper, and the dynamic nature of the printing process. To minimize disputes, it’s important to set clear expectations and include disclaimers on color accuracy.
4. **Paper Variations**
Paper from different manufacturers can differ in brightness, texture, and thickness. Even within the same brand, slight variations may occur between batches. Printing houses should provide samples for confirmation before starting a job to avoid misunderstandings.
5. **Machine Limitations**
Overprint accuracy and ink distribution are affected by machine precision. While modern presses meet strict standards, visible misregistration is still possible under magnification. Ink compensation systems also introduce minor color shifts.
6. **Cutting Size Tolerances**
Cutting machines have inherent tolerances, and size deviations are expected. For example, currency and security documents have specific limits, while general print jobs allow for up to 2 mm variation.
7. **Psychological Expectations**
This isn’t a technical error, but it’s a common source of conflict. Some customers expect perfection, which is unrealistic for mass-produced items. Clear communication and education about what’s achievable can help manage these expectations.
In summary, while many printing errors are unavoidable, understanding them can reduce conflicts and improve collaboration between customers and printers. Open dialogue, proper documentation, and realistic expectations are key to successful outcomes.
