How Sublimation iPhone Cases Are Made

Sublimation is a printing process used to transfer a design onto a compatible coated surface using heat and pressure. For phone cases, the process begins with a case or insert designed to accept sublimation ink.

Design preparation

The artwork is sized for the selected case model and prepared so important details stay within the printable area. Camera openings, edges and the shape of the case affect placement, which is why customers should select the exact iPhone model before ordering.

Printing and transfer

The design is printed with sublimation ink onto transfer paper. The printed transfer is aligned with the compatible case surface, then heat and pressure are applied using the settings appropriate for the blank material. During the process, the ink bonds with the coated surface.

Cooling and inspection

After transfer, the piece is allowed to cool and is checked for placement and visible printing issues. Small differences can occur between a screen preview and the finished item because displays, materials and production conditions vary.

Ordering the right model

Model selection matters because standard, Pro and other iPhone versions can have different dimensions and camera openings. Check your device in Settings or verify the model number before choosing a variant.
