The delivered package should identify the stitch file supplied by the vendor, the production sheet, and a visual preview. Machine-file extensions vary by equipment and shop workflow, so state the required format in the instructions when the receiving decorator has given one. A preview is useful for checking color order and general appearance, but it cannot prove how thread will interact with a particular garment.
A production sheet can document finished dimensions, stitch count, color sequence, trims, and other details supplied by the digitizer. Review those facts against the order before releasing the file. A design that was requested at left-chest size should not arrive at an unexplained dimension, and a required color should not disappear without a documented simplification decision.
The best physical verification is a sew-out on material that behaves like the final garment. Check small lettering, registration, puckering, gaps, outlines, thread coverage, density, and the way the design sits after the hoop is removed. A screen proof cannot reproduce needle tension, backing, thread, pile, stretch, or machine setup.
Use the 48-hour change window carefully
If the returned file does not match the approved instructions, request the change from the order page and describe the issue precisely. Include the affected lettering, color, size, sequence, or placement rather than a general “make it better” note.
Keep machine files separate from the logo master
The embroidery output belongs to its size, placement, and material assumptions. Preserve the vector logo master separately so later print, sign, web, or apparel work starts from clean brand artwork rather than a machine-specific stitch plan.
Approve the named revision
When a customer or shop stakeholder must sign off, use a current proof with explicit version history. Do not let an older screenshot or emailed preview become the accidental authority for production.
