When the finished crop differs from a pre-print guide, identify the last approved version and measure lost or shifted image content before assigning a cause or remedy. The approved guide may show the flat front-facing image, a digital representation of wrapped edges, or a preview created before the final size was chosen. The first task is to establish exactly what was approved. Then measure the finished object and identify which visible details changed, using the same orientation and a consistent reference.
Establish a single approved reference version
Retrieve the signed-off proof file, its timestamp, the agreed outer size, the declared front-facing image area and any edge-wrap treatment. Confirm that the document is the last approved revision, not a convenient earlier email attachment. Record the order identifier, final design filename and any notes from the person who approved it. If the guide was presented as approximate rather than production-accurate, that limitation must be acknowledged before attributing a discrepancy to a printing mistake.
Check whether the actual print was rotated, enlarged, re-centered, or assigned a different proportion after approval. A portrait photograph may have been moved to preserve a person's face, leaving less background on another side; that can be intentional only if the variation was approved. Do not treat a maker's presumed margin or stretcher depth as a fact without the job specification. Keep the original file and approved guide unchanged while creating separate annotated comparison copies.
In a family portrait, a child's hand sits near the lower-right edge in the approved guide but disappears around the finished side. Compare the signed front-facing proof, the documented finished size and a square-on photograph of the delivered canvas. Measure from the same recognizable feature to the visible front edge in both versions, and note whether the guide included the side-wrap region. The studio may discover an approved but misunderstood edge allocation or a genuine change after sign-off. Avoid stretching the object as a quick correction to this image-placement dispute.
Measure the visible difference, not just the overall impression
Photograph the finished canvas front-on with perspective distortion minimized, then take controlled detail views of affected edges. Measure outer width and height and, where visible, the boundary between front-facing image and wrapped side. Compare a stable feature such as the distance from a face or text line to the left edge in the approved layout and in the delivered object. Use a units-based table rather than estimating that one side 'looks a bit tighter'.
Pay attention to image loss, not only geometric drift. A small shift that trims empty sky may be less consequential than a smaller numerical shift that cuts off a hand, caption or signature. Record exactly which meaningful features were lost, cropped differently, or moved toward an edge. If the finished canvas is photographed at an angle, correct that perspective for visual analysis or use physical measurements; a smartphone photo alone should not be presented as a precision measurement.
Separate production causes from remedies
Possible explanations include a changed canvas dimension, a different scaling or centering instruction, a proof that omitted edge-wrap allowances, or a print finishing variation. They are hypotheses until the studio checks production logs and the actual job file. Ask for the file version, crop coordinates and assembly instructions used. An agreed tolerance, if one exists, should be consulted in its original wording; do not invent a numerical 'industry standard' to dismiss the discrepancy.
Summarize the evidence in a neutral report containing the approved guide, finished photographs, measurements, significant visual differences and the requested review. The appropriate outcome might be acceptance, a documented adjustment, or reprinting, depending on the contract and what the producer can safely change. Do not trim or re-stretch an already finished work in an attempt to match the guide without qualified advice and explicit authorization.
The strongest comparison is traceable: one final approved guide, one measured finished canvas and a clear list of affected image features. That allows the studio and customer to discuss a real crop variance without confusing preview conventions, perspective in photographs and unsupported claims about tolerances.
