JPEG (JPG)

Import the approved image into the method-specific software, set output dimensions explicitly, check crop and orientation, and confirm color management and any mirroring or underbase behavior required by that workflow.

Fit the image in the actual application without unapproved stretching. The RIP or driver may interpret resolution metadata, crop-to-fill, or rotate based on Exif; override those behaviors deliberately. Confirm the print preview matches the finished physical orientation and all important image content is within the safe zone.

Select settings from the machine, RIP, ink or transfer, and material documentation. This guide does not prescribe universal temperature, time, pressure, speed, power, or color values.

Separate image settings from machine settings. JPEG export quality, profile handling, and source pixel dimensions are file-side decisions. Ink limits, white underbase, transfer conditions, raster power, pass count, and similar parameters are process-side decisions governed by the shop's validated setup.

When documenting a job, keep the export settings and production settings in separate fields. The creator can report JPEG quality, pixel dimensions, and profile; the maker records placement, RIP interpretation, machine preset, ink or transfer system, and material. This separation makes it possible to repeat an accepted result and identify which side of the handoff changed.

Run a controlled proof when quality or compatibility is uncertain. Compare it with the approved target, record the settings, then produce only after acceptance.

For a new design or material, make a proof on the actual process whenever feasible. Record file checksum or exact version, machine, software, preset, material lot, and result. If the proof fails, change one relevant variable and test again. Do not silently substitute a lower-quality listing image.

Finish the item using the material and method instructions. Check that crop, trimming, curing, transfer, or coating did not change the approved appearance.

An output can be acceptable at the machine and fail after finishing. Recheck colors, sharpness, edges, and registration after trimming, curing, pressing, coating, or assembly. Use the material manufacturer's handling limits and cool-down or cure instructions.

Finishing is a separate quality gate. A print may be sharp before trimming but lose important detail at the edge; a transfer may shift after pressing; an engraving may need cleanup that alters perceived contrast. Inspect only after the applicable curing or cool-down period, and use the method's current handling instructions rather than guessing from the image file.

Inspect color under consistent lighting, image sharpness, dimensions, registration, finish, and surface defects. Compare against an approved proof rather than a random screen display.

The final test is the goodie, not the file viewer. Compare the product with an agreed reference under repeatable lighting and at a realistic viewing distance.
