Sources & Verification 6 of 8
Claims Verified
The format claims below are supported by the cited standards and documentation; production claims remain conditional.
Verified: ordinary JPEG is a fixed-pixel image; .jpg and .jpeg are common extensions; common photographic encoding is lossy; ordinary JPEG lacks transparency and multiple editable layers. Conditional: any specific print, transfer, or engraving acceptance. Not established: universal PPI, universal quality slider value, or a machine setting that works across suppliers and makers.
| Claim | Status and boundary |
|---|---|
| .jpg and .jpeg | Same JPEG format family; extension alone does not identify internal details. |
| Lossy photographic JPEG | Common and well documented; do not generalize to every coding mode in the JPEG family. |
| Ordinary JPEG transparency | No standard alpha channel; use another accepted format for true transparency. |
| Print resolution | Pixels divided by final inches is calculable; no universal 300-PPI rule verified. |
| Specific machine/material compatibility | Not verified; requires exact model documentation and proof. |
| Goodiee acceptance or live product support | Must be confirmed against current platform rules, not inferred from this research package. |
