AR The E-Proof Was Approved.Then the Customer Had to Payfor New Printing Plates.
Jul 31, 2026
Everything looked ready – until the trial film arrived
The pouch design was finished. We prepared the final e-proof and sent it to the customer for approval. The customer reviewed the file, approved it, and gave us permission to move forward. Based on that approval, the printing plates were made.
The next step was a trial print. We printed a sample of the actual film and sent it to the customer so they could see how the approved artwork looked on the packaging material.
That was when the problems appeared. Looking at the printed roll film, the customer noticed several details they wanted to change. Some parts ofthe artwork needed adjustment, and the customer no longer wanted to continue with the version they had approved.
The requested changes themselves were not unusual. The problem was the timing. Before plate production, changing a word, moving an element, or adjusting the layout is simply an artwork update. After the plates have been made, the same change can mean remaking one or more physical printing plates.
On screen, it still looked like a small artwork change. In production, it had already become a new plate cost.
The customer now faced an extra charge and a delay. They were understandably disappointed. From their point of view, they had only just received a physical sample. From the production point of view, however, the artwork approval stage had already ended.
That difference in expectations is the real lesson in this case. The e-proof was treated as a quick formality, while the trial film was treated as the final chance to review the design. In fact, their jobs are different.
An e-proof isnot just a file to sign
An e-proof is the last low-cost checkpoint before the artwork is turned into printing tools. It shows the version the supplier will use to make the plates or cylinders. When the customer approves it, the normal meaning is simple: this exact version is ready for plate making.
The trial film comes later and has a different purpose. It helps both sides see how the approved artwork prints on the real material. It can reveal print-quality issues, such as poor registration, missing print, or a result that does not match the approved file. It is not meant to become a second full artwork review after the production tools have already been made.
Why are details often missed?
Usually, nobody is being careless on purpose. People tend to look at the design as a whole: the colors, logo, images, and overall appearance. They do not always read every word, compare every number, or check the position of each item against the pouch structure.
The review may also happen on a phone screen, under time pressure, or after several rounds of changes. Sometimes everyone assumes somebody else has checked the product name, net weight, barcode, contact details, claims, or translations. A file can therefore look ‘right’ at first glance while still containing details the customer would not want printed on thousands of bags.

A fair way to separate responsibility
A customer should not pay for a supplier’s printing mistake. If the trial film does not match the approved e-proof, the bag packaging manufacturer should investigate. If the film matches the proof but the customer asks to change approved text or layout, new plate costs may apply under the terms agreed before production. Clear approval wording protects both sides.
Take one slow finallookbeforeclicking Approve
A careful e-proof review does not need to be complicated. It simply needs to be deliberate. Instead of looking at the whole design once, review it in three short passes.
First, read the content. Check the product name, flavor or variety, net weight, ingredients, contact information, warnings, claims, translations, dates, and every important number. Compare them with your original source information. Do not rely on memory.
Second, check the layout. Look at the front and back panels, top and bottom direction, barcode position, QR code, seal areas, zipper, tear notch, window, and any place where printing could be cut, folded, or hidden. Ask whether the pack will still make sense when it becomes a real bag.
Third, confirm the version. View the proof at full size, scan any working codes, and ask a second person to review it. Make sure everybody is looking at the same final file. Then save the approved version with the approval date.
Before you approve, ask these five questions
- Have I read every word instead of only looking at the design?
- Are names, numbers, claims, legal details, barcodes, and QR codes correct?
- Does the layout fit the zipper, tear notch, seals, and pouch direction?
- Has another person checked the same final version?
- Am I happy for thousands of packs to look exactly like this?
Ten careful minutes at the e-proof stage can prevent days of delay and the cost of making new plates.
The trial film should confirm how the approved design prints – not become the first time the design is truly reviewed.
Note: In flexible packaging, ‘plates’ may also refer to printing cylinders, depending on the printing process. Charges and responsibility should always follow the approved proof, the actual printed result, and the terms agreed before production. For more information or to request a bag quotation.
