JPEG (JPG)

There are no materials inherently compatible with JPEG. Compatibility is determined by the selected print or engraving process and its ink, transfer, coating, stock, or blank.

Match a JPEG-based image to the production process rather than the raw substrate. A photo can be printed on suitable paper, transfer media, or a coated blank only if the device, ink, media, and finishing system are validated together. Material compatibility cannot be read from image metadata.

Use the exact material approved for the product and documented workflow. Verify surface, coating, color, and printable area with the maker before final export.

Use a known-good material for the chosen process when evaluating a new JPEG handoff; otherwise it is hard to distinguish an image problem from a substrate problem. Record the exact stock and coating, not just a broad label such as 'paper' or 'polyester.'

There is no material universally recommended for JPEG. Recommend a material only within a named process and product: for example, a particular coated print stock approved by a print shop. State the supplier SKU or technical specification, the machine and color setup, and the accepted proof. A generic label such as 'paper' or 'polyester' does not establish repeatability.

A material cannot be declared incompatible with JPEG in isolation; an image file is not applied directly to stock. Reject combinations the specific equipment or material manufacturer disallows.

If the material supplier or machine manual forbids a process combination, a better JPEG export does not make it safe or workable. Stop and select a different validated material or method.

There is no table of 'JPEG-incompatible materials' that stands on its own. Instead, ask whether the selected machine, ink or transfer, coating, and stock form an approved combination. If a material is not supported, replacing the image format does not automatically solve the physical problem. Seek an alternate material or production method and make a new proof.
